Kobalt air compressors are the house brand of the Lowes of big box store fame.
Made for Lowes, the Kobalt line of air compressors is powered by electric motors and come in portable and fixed styles. The range of motors is from 1.5 HP up to 5 HP.
These motors power a range of Kobalt compressors, small 3 gallon tanked units with a 1.5 HP motor up to the 5 HP vertical fixed style with an 80 gallon tank.
We would categorize the Kobalt line of air compressors as mid-use. By this we mean that we would have no problem acquiring a Kobalt compressor for our home workshop or garage. We might even purchase a Kobalt compressor for our work, assuming that our use of compressed air was incremental, and not used continuously. If we were looking for a compressor to do work for us 8 hours a day, five days a week, we probably would not buy the Kobalt air compressors range.
Here’s why. After sales service.
Who Makes Kobalt Air Compressors ?
Like all department stores or big box stores, the stores do not make their own house brand products. They outsource, and that source will change from time to time.
At any point you might buy a Kobalt air compressor made by YY Company, and it may be possible to get the same model air compressor made by ZZ Company. Where do you get parts? Who do you talk to about service?
Your air compressor will eventually break down. When, not if, it does, who looks after you?
That’s why we would tend to steer clear of any big box store house brand air compressor if we needed one for production purposes. We would always go to an industrial compressor distributor, one that has the expertise and the parts to get us back up and running when the need occurred.
Having said all that, for light use, no worries. Buy the cheapest Kobalt air compressor that does the job – that means has the air flow you need for your air tools – and when it breaks, by and large you’ll toss it out and buy another.
Do you have a Kobalt air compressor? Care to share your thoughts on them? If so, please provide the model number too so that others can read how you feel about your Kobalt.
Need a wiring diagram for a kobalt 8 gal compressor.
Brent, I’ve uploaded an image of what I believe to be your air compressor. Is this the one you have? If so, the wiring is pretty straightforward I think. Here’s how I would do it if this were my air compressor. Two wires come ion from the power cord as shown in the photo. One of those power wires goes first to the ON/OFF switch and then on to the pressure switch. That same wire… Read more »
I have Kobalt Model# 3332643. Air is leaking from around my air pressure regulator knob. I have had it since about December… I mostly use it to fill tires / to dust my PC. Planned on eventually getting some air tools.. but haven’t yet. I usually have the tool pressure at about 90 psi. Any advice on where I can get get parts to rebuild that valve / dial section of the regulator? I attached… Read more »
Odd that air would leak where you have indicated. You have put a wrench on the flats and tried to tighten down the innards, have you? Try that if you haven’t. In the drive to make compressors cheaper off-shore manufacturers use cast manifolds for the discharge components, and few companies sell them. Lowes certainly doesn’t, and parts for the low cost regulators are almost impossible to find too. If tightening the innards doesn’t resolve the… Read more »
I haven’t tried it yet, but certainly will. I just figured out where it was leaking last night. Hopefully we’ve kept the receipt.
Thanks for your quick reply.
You are most welcome. Let us know how it turns out, won’t you?
Hi, I have an Kobalt 20 gal oil free compressor model #0332041…very lightly used but a couple of weeks ago when I went to start it up, it ran and pumped up pressure…when the pressure was used and or bled off the compressor would not come back on and build any more pressure. I did not have it plugged in with an extension cord and I had the pressure set to 75 or 80 pounds…..I… Read more »
Get the cover off, and see where the wire from the ON/OFF switch goes. If it goes to a pressure switch that has an unloader valve, then that unloader valve may not be functioning. Other than that, have a look at this page, read the pages that apply, and then add a comment with what you found when you checked, please.
Hi i have older 26 gl with 1 and 1/2 hp my problem is that when it gets uo to 65 70 lb the moder slows down and the reset button pops out. Is this worth fixing? It was free
Free is a good price. The troubleshooting page on this site with links to issues about why compressors bog down will provide lots of info. I believe the button pops as the compressor motor is overheating. There could be a number of reasons, most covered on the pages already on this site. Have a look. As to whether it’s worth fixing, depends on how much you want to spend, whether you use the compressor a… Read more »
I have kobolt model number 0320541 and the first time using it the bolt in the compression cylinder sheared off were can i get another bolt
Howdy. I believe this compressor was first introduced by Lowes in 2014 or thereabouts. Wondering how you have a compressor of this vintage that’s only been fired up once? Anyway, Lowes does not have parts as you already know. Best I can suggest is if you can get one of the bolts then visit an industrial hardware outfit and ask them to identify the thread and supply another like it, though maybe take it up… Read more »
I havea kobalt 20 gal 1.8 hp and the fan on the mortor broke can i get a replacement for it part #isj1950320168
I have a 20 gal 1.8 horsepower Kobalt compressor. The issue I’m having is while using the compressor without warning air starts rushing up around the regulator knob. I have taken the knob off and replaced the o’ring on the bottom of the knob assembly. This works for a while, but it does it again, and each time I replace the o’ring it fixes it for a while, but it blows another. I’m hoping somebody… Read more »
What pressure are you running the air tool at, and what pressure is in the tank?
I only run it at 75lb I never run it any higher than that for what I use it for.
If the tank pressure is higher than the 75 PSI you’ve got the regulator set for, and air is blowing up around the regulator, presumably from the regulator body and not a leak at the fittings or pipe, then I would surmise your regulator needs a new diaphragm.
I have a Kobalt 8 gal compressor (model # 0300841) that was leaking from the check valve, I ordered a new one but received the wrong part. While I was messing with that, I noticed the compressor didn’t shut off at 150 psi like it should so I replaced the pressure switch. Now I have a new pressure switch that still doesn’t seem to work properly and the old check valve that still leaks a… Read more »
“Not shutting off correctly”? What’s happening? How high does the pressure get to?
I continues until the PRV goes off
OK, if you pull the wire off the pressure switch with the tank full of air, past the normal cut out by 10 PSI, and the compressor stops and when you connect the wire again the compressor starts even with a full charge of air in the tank, then it’s pretty much got to be a bum switch.
I have a Kobalt 8gal, 1.8Hp Running compressor oil less unit. I can fill the tank with air just fine but when I attach the hose to the unit it will knock and not fill when more air is needed. I have tired it plugged into the wall and also with an extension cord. I have also emptied the air out of the tank several times with the same results. I would appreciate any ideas… Read more »
So, empty tank and the compressor starts and runs, air in the tank, and the compressor will not start, is that right? Oh, and avoid the extension cord. They’ll cause a motor overheat unless the cord is of sufficient gauge for the distance.
What do you mean the “unit will knock”? Please clarify.
We have a 20 gallon, 1.8 hp, 150 max psi, 4.0CFM@90psi. We need to replace the air pressure regulator knob and the internal parts of the air pressure regulator. Where can I fin d these parts? Thank you
Please remove the plastic cover from the whole assembly, and then add a photo showing the complete piping of the array. It may be that this is a proprietary manifold, and you may not be able to replace just the regulator, but until we can see what’s under the cover, we cannot be sure.
Did you happen to find a fix? I’m in need of the same thing
I have a 20 gallon standing Kobalt air compressor, it vwill run for about three to four minutes getting to about 60 lbs of pressure overheats and quits running. It is supposed to pump up to 150 lbs but does not make it. Ran fine last summer but now has started this.
Tom, any change in the power supply? Not using an extension cord? If no to both, please read the pages found here for some tips: https://fix-my-compressor.com/air-compressor-problems-and-fixes/
I have the same problem with a Kobalt 20 gal compressor. There is a thermal cut-off switch that is attached to the coils of the motor, as seen from the back. It is about 3/4″ long and wrapped in clear shrink tube. The problem is that this device is crimped on and the crimp is a poor job, if you look at the connections they are black from burning and overheating. The problem is that… Read more »
How do inget power cord out of black box
Joseph, what black box are you referring to? Is it the black box on the compressor that the power cord runs to? If so, unplug the power cord, and look at the top of or around the bottom of that box for screws that are holding the cover on. Remove them and the cover, and you’ll see where the power cord wires are attached. Does that help?
Will never purchase Kobalt air compressor again…….There is no repair available the 20 gallon and higher …..Stay with Husky for sure , made by Campbell Hausfeld…From Home Depot
I have a 20 gallon, 1.5 HP, oil free Kobalt air compressor (model # 233885). When I turn it on, it runs but I begin to smell something burning within seconds. So, I shut it down. Any suggestions?
Boy, hard to be specific without knowing what’s heating up, Tom. This is recent, and ran before with no issue? I don’t believe this one has oil-added by user, so I’m guessing its not out of oil. Lot of hard long use? Any change in the power supply… extension cord being used, power bar, like that?
Can you provide any more details?
It has always been light duty use and has always been in my garage. It has basically been used to inflate tires. I have probably had it for 15+ years though. It is plugged directly into the outlet with no extension cords. Maybe I can look closer to see if I can pinpoint the burning smell later this week. I apologize for the lack of details in my first post. Thanks for the help!
I have a Kobalt 8 gal compressor. When I turn it on and pressure starts building, I hear the unloader valve start venting to the atmosphere. When it finally fills and cuts off the valve still vents until the compressor tries to start to refill but it cannot restart (just hums and blows the circut) Ive read the unloader valve page on this site and am still unsure if its the unloader valve or something… Read more »
Brian, if air is leaking from the unloader valve after the compressor stops, where is it coming from? The compressor tank. Dump all the air, remove, clean and reinstall or replace the tank check valve, and then post another comment about the symptoms the compressor is showing after you have done that, if any. See the pages on compressor tank check valve for more info on that part if you would.
Mine is doing the same thing!!! Air bleeds out through the bolt with the pin hole in the center. Took it out, cleaned it and reinstalled with thread tape and it still leaks! Any fixes?!?
Please check and make sure the tank check valve is not leaking, will you? Let us know please.
Pulled the tank check valve and the spring that holds the diaphragm in place is in pieces. Currently looking for a new valve but it’s hard to know what to get as I don’t know NTP pipe measurements! I ordered one hopefully it’s the right one!
Here are some pics. Parts number is wcfadx.02.03
I have a Kobalt 5 gal air compressor. Recently it started overheating. I need to unplug it several times and wait before it will fill the reserve tank. Then when full and I’m using a tool it will kick back on, fill a little, then I repeat the process. Where should I look first?
Tony, are you using an extension cord to power the compressor? What air tool are you using, and any idea what CFM that tool requires to run properly? What is the motor HP of your Kobalt please?
I need help. My husband is trying to figure out if he can order a replacement part for this air compressor. It’s model # 0300841. He’s looking for a pressure/tool regulator. Do you know if he can order one?
Given that Lowes is still selling this model, it’s a logical question to ask the store where it was acquired. Is the unit still under warranty? Get them to replace the regulator or the whole compressor. If not, pull the plastic cover off the assembly and add a photo as a comment here of the existing regulator and we’ll see if we can help you find a new one.
He needs the silver piece in the picture
Thanks for the photo. By the “silver piece” do you mean the “silver” metal tee into which the air line is connected at the top, the PRV on the left, the discharge coupler on the right and nothing that I can see at the bottom? Is this where the regulator goes? Is it the “silver” piece you want or the regulator that would be attached at the bottom of the tee?
He needs both pieces
Hi Kim. I’ve uploaded a photo of what I believe your compressor looks like with the cover on. Is it correct? If it is, then I can see where the image matches with the manifold photo you uploaded… mostly. Am I correct in understanding that the regulator fits in the “silver” piece at the bottom of your image, and the regulator gauge is not attached to the regulator but added to the cover, and plumbed… Read more »
I have a kolbalt model number 153-0142 and the pressure regulator leaks air. After I took it apart and j b welded the leak , another one popped up. It continues to leak and can I get a new regulator ? I can’t seem to find the the right part.
Please reply with a couple of photos of your compressor and a closeup of the regulator. I cannot find this model anywhere, and don’t know how to offer advice since I cannot see the area where the problem is occurring.
I have an air compressor model # 0300841. The manifold broke where I hook up an air hose to. I can’t find a part # for it.
No part available.. then you’ll have to cannibalize a broken one, or make your own. See if there are any on the market that might be close to what you need. If not, get the fittings to make your own. They are available, and may actually save money over buying a new one, if you could find it.
I need a manifold part # E101627…..all sites say discontinued. Is there a replacement part #?
No longer available for sure, Glenn. If you Google “build a compressor regulator manifold” you’ll find a bunch for sale on ebay. If none of those can be modified to suit, you may have to make your own. That’s not as difficult as it may sound though the results may not look particularly cool, they will work. Visit a good plumbing store and you’ll find lots of brass fittings that you can assemble into any… Read more »
Where do I get this part!!
So, what I think I’m seeing is a manifold from the compressor, on which is the two gauges and the regulator, yes? What compressor model is it, please? Without that information it’s pretty difficult to help.
It’s an older machine cannot find book or anywhere on machine with model number it is manifold with guages a few if helps if not I keep looking thanks!!
Allen, thanks for the photos, though I couldn’t see on any of them the actual location of where the original assembly was located? In the first photo, the part that extends towards the viewer is placed where on the compressor, please? If you Google “kobalt compressor manifolds” and then just “compressor manifolds” you will find many. If any can be adapted to fit into your Kobalt, all you need to be sure about is that… Read more »
the model # for that 8 gallon horizontal compressor is 0300841 I also am looking for the manifold and so far have had no luck.
Yeah, I see that. Even their catalogue parts list doesn’t show the manifold as a part. So, what’s with your manifold? What’s needed to fix it?
On the same compressor as in this picture the kobalt 8 gal i need to add a manifold i found one on Amazon but it also comes with a on and off switch. Do i need to wire the aftermarket switch in or can i use the original one. Also does anybody know if the pressure on of switch is on tbe unit or on tbe regulator manifold?
If your compressor is the Kobalt 0300841 too, then the upper tank pressure will be 150 PSI. From the pictures I have found, I suspect the pressure switch is what I call a “mini-switch” and installs right into the tank. You’ll have to pull the cover to check. I doubt it will be part of the manifold.
If the new manifold comes with a switch, disable and remove the old one, and use the new one.
Sounds good thank you. One more Q the new switch looks to have a inlet for a pressure tube, do i just disregard that since the “mini switch” is already inline in the tank. i assume that will stop the motor once its at max psi right? Thanks again
Miguel, remove the covers and make sure that the pressure switch is installed in the tank first. If it is, then do not use the new switch. Sorry, I thought you meant ON/OFF switch in your earlier post, not the pressure switch. What you want to do now is remove the covers and take a photo of all sides of the compressor without the covers, and add these in a new comment, along with a… Read more »
I have a 1.8 hp 8gal kobalt. The check value started leaking constantly with every pressure up. Is there a way to fix the problem or do I have to replace the part?
Jim, my answer will depend on what you mean by the check valve. How do you know the check valve is leaking? It’s in a fitting stuck in a tank, is it not? Please advise what you mean by a check valve, and even, maybe, upload a photo? While that is difficult in the thread, you can start a new post on the same page and upload a bunch of photos there. I’ll have a… Read more »
Where do you find parts..I have a 8 gallon and the hose from the tank to the regulators just crumbled and where you plug air line in just crumbled just by tightening it up wth
Hi Scott. Sure want to help but I’m a bit confused by your questions. When you say the “hose from the tank to the regulator” do you mean the cast pipe? Just a different word for what you mean, I guess, but until I know that, I’m not quite sure what part you are talking about. And where you plug the air line into, that’s the coupler on the same pipe, yes? Any change you… Read more »
I have a 1.8 HP 20 gal Kobalt A/C Model 0332041 that I just bought recently without giving much thought to where I would put it in my garage shop. It is a replacement for an old horizontal compressor that I had below my workbench. I didn’t do due diligence and measure where I would place the new compressor. The vertical Kobalt won’t fit below the workbench and i don’t really have anywhere else to… Read more »
If this were my compressor, I wouldn’t try to run it on it’s side. Even though it’s user-added lube oil free, that doesn’t mean there is no lube inside. Also, if on it’s side, the tank drain will be in the wrong place. Sorry, but I don’t advise running it horizontally.
(You could) dig a hole under your work table to fit the compressor……make sure plenty of airflow (open space) around the compressor.
good luck
I have a Kobalt Direct Drive Model 103798. When turning it on all you hear and get is a loud fast clicking noise. Was told it was the regulator. I changed that but no change. The electronic circuit board seems to work fine, all that is displayed is an upside down “U” on the display and the normal pictures. Thoughts?
I’m not seeing too many air compressors (actually cannot find any) any more with digital regulators and controls. Reason being, in my opinion, they are prone to failure and very expensive to replace if you can find parts. This page may help: //fix-my-compressor.com/clicking-air-compressor/ .
This one may too. Good luck.
I have a Kobalt 0332041, 3 yrs old, the tool pressure adjustment blew apart. I found the top of the adjustment knob and a spring on the garage floor, but nothing else. Personally, I have never heard of a regulator blowing apart, (it would seem that this could be an extreme hazard, with the pressure flinging parts about at a pretty good velocity.) So what is a replacement part for this? Is there a place… Read more »
RFM, that part should be available at Lowes where this brand of compressor is sold. Failing that, Google air compressor regulators and you’ll find many. Pick the one that is the same as the one you removed. You will not likely find parts for it, though the whole regulator is priced in the $15-$20 range typically. Odd that a regulator blew apart, as the OEM regulator pressure rating is typically well above the maximum pressure… Read more »
Hi my name is Tony and I have a portable 8 gallon 1.8 horsepower 150 Max Pressure Cobalt air tank my problem is lightning struck the power pole outside my house and then when we tried to turn on air pump it wouldn’t come on when I unplugged it I noticed that the grounding pin for the plug was burnt and had a hole in it now the compressor won’t run is it worth trying… Read more »
Well, a plug is cheap. Change the plug, and then use a multi-meter to follow the power to the compressor. With the tank empty, power should be crossing the pressure switch and flowing to the motor. If it’s not, where does the power stop?
I bought a 20 gallon kobalt compressor at lowes. I needed an upgrade as I wanted to do spray painting. I have not done any painting yet just finish nailing in my shop. I have had this compressor about 18 months then it started cutting of at 70-80 lbs. it is rated for 150 psi. long story short. the thermal fuse inline was failing. I called the help line and they told me there was… Read more »
Calvin, I am happy to approve your post, however, must inform you that my website is not Kobalt, nor do I have any official affiliation with them. If you wish to critique Kobalt at the source, you will want to contact Lowes head office, as Kobalt is their house brand air compressor… among many other items. Good luck.
I have a Kobalt 60 gallon compressor. It had been wired up and working fine for a couple of years. Then I moved. When I reworded it in the new shop it only runs for a while then the reset button on the motor trips. What can be causing this?
The reset trips because the motor is getting too hot. That could be because the motor or a motor capacitor has failed, or it could be simply that you aren’t feeding the compressor enough power to ensure the motor runs optimally. What HP, what breaker amperage for the compressor circuit, what length of wire run… please provide details about how you are getting power to the compressor. If it’s a 120 VAC, and you are… Read more »
3.7 HP. 208-240 volt. I have it hooked to a 30 amp breaker. It’s about a 4′ run. Same exact setup from when I moved from the old shop. I brought it with me and tied into the new service panel.
OK then, it’s not the power supply from the panel, Melvin. I still believe it to be because the motor is getting too hot and to me the next thing on the check list is the start capacitor. Please check yours, there’s a page about how on this site. That it may have failed when you moved the compressor may only be coincidence.
Yes I read that about the capacitor. I’ll let you know the outcome. Thanks.
I have a kobalt 8 gallon electric air compressor and after the tank filled up with air then as i was using it and the pressure went down the compressor kept sounding like the motor was gonna die and i maybe have only used this compressor around 5 times. Why would it sound like it’s gonna die on me while trying to fill back up with air?
Chad, please have a look at: //fix-my-compressor.com/compressor-wont-re-start-when-air-is-used/
Have kobolt 8 gallon air compressor air leaks out of check valve like it should but does not stop. When it’s starts to recycle new air motor does not kick in or sounds like it wants to try but goes out. The wrong check valve was sent to me so will send back. Just thought I’d get your thoughts . Thanks
I looked at some pictures of what I believe to be your compressor, but could not see where the check valve was. Is it one with a small hole in the top? You say air leaks out of this OK, and the leaking air should happen while the compressor is running and for a short time after the compressor stops. If there is air bleeding out this hole all the time and while the compressor… Read more »
I have a Kobalt 26 gal VLK 1582609. A friend of mine borrowed it and when he returned it…after midnight… the motor was missing, long story he tried to repair it and was not too successful. !,5 hp. Where do I find one. Thanks
Very odd that, considering that it is necessary to purchase both the motor and pump as a single assembly. Current cost is $200+. If I was in this situation, I’d be buying a new compressor, one comparable one is around $170, quite a bit less than just the pump and motor. Good luck!
I am searching for a check valve for a Kobalt air compressor(20 gal. 1.8hp) model #0332041.
Pull the existing tank check valve, if you have not already done so. With it nearby, Google compressor tank check valves, and acquire one that looks the same as yours. As long as the new one fits in the tank thread, and the pump head line connects, and the line to the unloader connects if this model has one, you’re good to go.
My compressor check valve failed, I did order new check value after install it run ok but when the air pump between 90psi to 120 psi the pump made a weird noise, but the old check valve back no noise but air was leaked agian. Does anyone know what happened. My compressor model # KLA 1883054. Thank you
A weird noise might mean a gasket in the pump is letting go. When you say it’s still leaking, where is it leaking from?
Hi Willyr, it’s still leaking when I put the old check valve back( air leaked under compressor switch,) the new check valve is good but have a weird noise. I ordered this check valve # CTRD 3812-PLUS.
Thank you
When you mean gasket which one( head gasket or gasket cylinder) and is that easy to do it? Thank you.
If air is leaking from the bottom of the pressure switch, that’s an indication that the tank check valve is leaking.
Yes, but I ordered the new check valve after installed the pump made a weird noise, but when I put the old tank check valve back pump run good no weird noise but air leaking. Thsnks
I suspect that the weird noise is being generated by a gasket leak, and that’s occurring because the new check valve works, and is generating some back pressure (normal amount) as a result. That no noise occurs with the old tank valve is likely because the flapper or ball check isn’t generating back pressure, as it doesn’t work. When the tank is full, the compressor stops, air leaks back up from the tank through the… Read more »
Depends on how handy you are. I cannot tell you if it’s easy or not for you. If you’ve taken things apart and put them back together successfully, and are creative in terms of making gaskets when you may not be able to find an OEM version, then away you go.
Thank you very much Willyr , so do I need to buy both head and cylinder gasket or which one . Thanks again
It is my experience that pulling a compressor pump apart can damage the pump gaskets. Therefore, I recommend that you replace them all, ensuring that when the pump has been reassembled, that the process did not damage an older pump gasket.
Thank you very much for all your help.
You are welcome. Good luck with the fix.
Hi Wiilyr, I need your recommendations. my compressor is about 12 years old and since it got a problem and I did ordered pressure switch, tank check valve, 90 degree elbow brass, felt filter, hose, now should I order gaskets kit to fix it ? I’m just afraid when I open it up some more stuff get problem like crankshaft,bearing,piston …ect. Should I buy new compressor or fix it? And between Kobalt 30 gal and… Read more »
I cannot advise you as to whether it’s better to fix or replace. Your skills and your wallet will tell you that. As to which is better, Husky or Kobalt, thought I don’t know for sure, I wouldn’t be surprised to learn they were made by the same factory. Best air capacity, best warranty, best potential for spare parts, best price… all criteria I use when I need to buy a compressor.
I have a kobalt 1.5hp 20gallon air compressor model number 03342041 i am looking for a regulator part number WCFATY.04.05, do you have any suggestions?
Sorry, without a model number of the compressor, I cannot make any recommendation, as neither of the numbers you provided result in any information on line. Perhaps you might add a comment here with a photo of the regulator you want to acquire?
I have a 60 gal Kobalt air compressor that is spitting a fine mist of oil out of the breather. I changed the oil and still appears to be happening.
If by the breather you mean the air intake, that suggests that the intake valve on this Kobalt compressor has failed. A pump repair kit with valve plate and gaskets is in order.
Help. I need some parts for a Kobalt 0200382 compressor…but can’t find a parts list ANYWHERE online. It’s a 3gal, 1.5 HP 150 Max PSI 2.6cfm 90psi one-tank compressor I bought at Lowe’s
Hey Ted i have the same compressor and i had the pressure regulator break on me too. I needed a fast fix so i headed over to the Home Depot and bought an inexpensive pressure regulator and a pressure gauge plus a fitting to get them all together. Works great, i was able to get my project done and for under $30 fix
I have a Kobalt 20 gal digital air compressor 1.3 Hp Model # 215908. It recently started making this loud squealing noise and shutting down when trying to re-fill the tank with pressure still in it. Like when I use so much air it comes on making a loud squeal and shuts right down. Turned it off, unplugged electricity, re-plugged it, turn it on, same thing. If I let all the air out of it… Read more »
My first thought was that a belt was misaligned, but this is, I believe, a direct drive compressor. Since I cannot see under the cover, and have not been able to find a photo showing me detail, I wonder about the unloader. Can you pull the cover to check does this model have a small hole in the fitting between the pump and the tank? If so, that hole is supposed to bleed air all… Read more »
Oh no I don’t remember seeing an notification email about your reply I am sorry. That does make sense. I need to get a set of star bit hand drivers, I have star bits or Torx, but they are for my impact and an apex will not go down the hole to take the cover off. Yes it is direct drive piston, no belt if I am not mistaken. I plan on getting a set… Read more »
Ok I took the cover off and it is belt driven. It is the belt making the squealing noise, it has a flat spot on the ribbed belt. As far as why it was shutting down I don’t know, maybe getting too hot? Anyway, I need a replacement belt.
If the belt was squealing, that would suggest that something was stopping the belt, while the pulley turned. Just a guess, but I think you’ll need more than a belt. I’d be looking at the cylinder / piston too just to see what’s what inside.
I agree, I haven’t taken it apart but I did spray wd-40 and it does seem to run smoother. I already ordered a new belt because the one on it does have the ribs wore down in one spot. If it is on that spot it will not turn the piston. The air intake tube to the piston was fallen off and there is no air filter, maybe that is what caused it to wear… Read more »
I have a 60 gal. 220 v compressor. Been great for years. Suddenly l turn it on, and it sounds great until about 70# and then sounds bogged down, making other weird noises. I then noticed a burning smell so I shut down. Have not read about this type problem so I don’t know where to look
Don’t know the model number so don’t know if this is belt driven. Is the smell a burning belt, or is it coming off the motor? What weird noises, please?
My Kobalt air compressor VPK0880803 recently stopped building up pressure. It maxes out at 40 psi and the engine stays on trying to build it up. I pulled apart the unit today and noticed that the piston ring is cracked and warped out of shape. That would explain it. Called Lowes but they don’t have a parts program or a way to order parts. Called the number on the back of my compressor and it… Read more »
No parts means no parts, Brian. I can’t find any either. I do see a host of compressors that are 1HP and some 1.5HP in the $100 range. If you even find the part for your compressor, I’ll be it would equal a big chunk of the $100 for the part, gaskets, etc. So, in this case, painful as it is, if you cannot find the same compressor (Sanborn you say, yet I’ve found the… Read more »
I just googled 047-0101 and found several websites that have the part. It looks like it is connecting rod/piston assembly so you get everything. The sites I looked at were in the $28-$30 range (before shipping.)
Brand: Kobalt
Model: LLA4508065, 221580
I have Kobalt 80 gallon unit and its work great for about 5 years now ,but now I have to turn the switch on and off a dozen times to get it to turn on , I am worried it may not turn on at all dont know whats going here any one know ???
I have a 3 year old Kobalt 26 Gal 125 PSI oil less compressor that has never worked from the day I purchased it. Model #37296 serial # DDD9184. I took it back to store and was told the tool pressure was not set correctly. When turned on it builds to 60 Lbs and shuts off. Hit reset button and it builds to 90 and shuts off. Reset button will not turn the compressor back… Read more »
Sorry that you’ve had such a terrible time with your Kobalt compressor Ron. I’m sure I cannot agree to the “tool pressure being not set correctly” as being the cause. If you dial the regulator up to 100 PSI, then that’s what should be going down the line to the air tool. If the compressor cannot, however, build pressure up to 100 PSI, then no matter where you set the regulator, the air tool will… Read more »
Hello Clint. If you have not done so, you will need to pull the cover from the control panel. Examine the regulator and how it is plumbed into the manifold. We suspect you will find that this is a typical general purpose regulator, unless yours is digital, then it’s more complex. Have a look at the regulator page on this site for more guidance. We suspect that replacing your regulator with a non-OEM shouldn’t be… Read more »
I have a kobalt 20 gal compressor model 0332041. Had it for over a year and it worked great until I had to turn down the pressure and my regulator stopped working. Now I I have a full tank with no way to get pursue to my fills and I can’t seem to find the right part. It shows in the book that the part number is wcfaty.04.05 but i can’t find it on any… Read more »
you can order it from 1-888-3KOBALT, it was 18.75 for part, tax and shipping
I have a Kobalt Model 37296 Air compessor and I need the start capacitor. But when I look around I only find them for 250 volt. the bad one I have is only 125 volt. Was this a special item for this compressor only?
Not to our knowledge is it special, but possible. Regardless, check the range of voltage for the capacitors you have found. Many (most) are rated 120-240 Volt, and if that’s the case with the one you found, and it has the same range for MFD.

I am going nuts trying to find an unloader valve for a Kobalt 30 gallon air compressor with the model numbers 215921 (KLA1683066) on it. Campbell Hausfeld sent me a check valve instead and I can’t find what I need…. I am in Panama City Fl area, does anyone know where I can get help?
Mitzi, we have been able to determine that the part number for the switch may be: 034-0184, though we cannot be sure as we cannot find an image of your compressor clear enough to identify the switch. We mention the switch because the unloader valve is a part of the switch. Please Google “pressure switch 034-0184” and when you see an image of that switch, make sure it looks like yours. Or, start a new… Read more »
@mitziHarless… have you looked here?
Portable single Stage Electric Air Compressor
I have a 30 gallon digitech plus air compressor that blew out 4 30a fuses. On the front it says made in USA but I found the compressor saying made in Mexico
I bought it 8 years ago for the past 5 and a half years I have been wanting to fix it but haven’t been able to till now.
Why is it doing this?
We moved this post to the Kobalt pages as Kobalt makes the Digitech air compressor. This compressor has a smaller HP electric motor, and as such, blowing 30 amp fuses suggests a serious electrical problem. While it is possible that a failed capacitor may be the cause, we surmise that there is more likely a fault to ground somewhere in the electrical circuit, possibly in the motor windings, and that’s where you want to focus… Read more »
The metal around the piston fractured. How can I get a replacement? Model 37296. 26 gallon 159hp. It’s a 2008 model. It’s been sitting for 5yrs. Now I need one and can’t buy a new one. It is missing pieces of the metal shroud so welding is not an option. Thanks for any help.
You aren’t alone. We did a search and found this article: http://www.about-air-compressors.com/kobalt-compressor-37296-casting-fracture.html. They appear to have been a high price for a compressor with such a poor track record. You can acquire a whole new compressor of the same size for $100-$200 should you wish. A search on resale websites will most likely turn up some of these compressors should you wish to replace the fractured parts by cannibalizing another compressor. We know of no… Read more »
I have a Kobalt 60 gal model number 221565 with the condor switch and unloader valve. The unloader is plastic with a type of push-in ferrule compression fitting on the line. When the compressor reaches about 60 psi, it blows the line off the unloader. I pulled the check valve and cleaned all the crud out of it and made sure the spring still works, and it does. When I cut off the motor, the… Read more »
When you say the unloader is plastic, we take that to mean that the unloader line is plastic, yes? If so, over time, the plastic air line loses some of its elasticity. If that has happened with yours, then that may account for the line blowing off the instant fitting inside the pressure switch. If there is enough slack in the line, try cutting off 1/2″ or so of the line, and reinserting it. That… Read more »
I have a kobalt 30 gallon oil less compressor. its been a great compressor until lately i had noticed an air leak.. i finally took it apart and found that the compression fittings from the pump to the tank have a small air leak… i took it off thinking this should be an easy parts to find. 3 weeks later i haven’t found anything.. i;m about to reuse the same line and do some type… Read more »
Going nuts here. Bought a Kobalt VT6389 30gal compressor in August. It suited my needs perfectly and I hit a good price and sale. Honestly, it sat in the shop for a while until I got around to plumbing air lines. I did fire it up a couple of times, but never drained the tank until the motor kicked back in. Here is my issue. The tank fills to 150psi with no problem. Once it… Read more »
James, please, don’t go nuts. Your air compressor isn’t worth it! We suspect your humming compressor has a power related issue. We assume it’s 14/2 wire that feeds the socket into which you plug your compressor. No extension cords, right? How far is the socket into which you plug your compressor from the power panel. If it’s a long way, amperage drop over the long run may just put your motor out of the sufficient… Read more »
