Kobalt Air Compressors

I’m trying to find a Kobalt Air Compressor model# 0332041, replacement regulator.
Kobalt part#- WCFATY.04.05.
The nomenclature on the compressor is 20 gal, 1.8 HP, 150 max psi.
The attachment is the exploded view of the parts page and the part is #30.
I’ve contacted Kobalt, Sears, Lowes, and 3 online parts links with no success.
Thank you in advance for your assistance.

I have had my compressor 215902 for more then ten years and have had no problems until about 6 months ago. It runs and holds air but when I try to air something up it doesn’t work it will not let any air out and I have tried everything I could think of

I had a piston and the fan break on the pump for my Kobalt 0300841. Is there anywhere I can order parts for this model?

i have an older 60 stand up Kobalt compressor. I bought it used worked good for a couple of years now air is leaking out of what appears to be an oil breather. What is my problem? Any idea.

Kobalt air compressor 20 gallon model number 0332041 replacement part tool pressure regulator, 3 year old, need to find a replacement tool pressure regulator WCFATY.04.05, have searched google and web, no luck, any help greatly appreciated..
Tucson AZ

I have a Kobalt 0300841 8-Gallon Portable Electric Horizontal Air Compressor.
The machine does not shut off when it reaches pressure so I assume t needs to have the pressure pressure switch replaced.
When I removed the two screws holding the cover, the top only comes up an inch or so.
I don’t want to force it and make my problem worse.

Am I missing another screw or something?

Where can I get an exploded view of the unit so I can see how to proceed?

Great! The parts description and numbers weren’t part of the jpg. The pressure switch that I was referring to is mounted under the motor and looks like mounted to the tank.

Can anyone please help, i was draining our 80 gallon compressor and the piece that screws on the screw came off and now i cannot find it. Where would i get another one like this to replace it?

Yes two wires that come out of bottom of motor on a 26gallon quiet tech compressor ones power cord and other don’t know

Both tires are bad on my air compressor. How do I change them?

I just bought a Kobalt QUIET TECH 26-Gallon Single Stage Portable Electric Vertical Air Compressor. Got it home, turned it on, nice and quiet, built up to the max 150psi in about 5 minutes. Then using air tools pressure dropped well below the 120psi kick in pressure, but the motor never came on again. Went back to Lowes, got another one, and it did exactly the same thing. The manager at Lowes asked me if I laid it down to transport, which I did, But I don’t see how that would have an effect with a non-oiled compressor which is brand new with no water in the tank.

It may have attempted to start once, but that was it. Maybe pointing to the bad unloader valve symptoms I’ve seen discussed?

Any ideas????

Update:

I just observed the unloader valve while the motor would not run and tank pressure at about 75psi. The pin was all the way up, and pushing on it did nothing. Released all air from tank, turned switch on, and it’s running once again. While building pressure the unloader pin is now down (extended) and it I push on it air is released.

I have a Kobalt 60 gallon, model #vt636200aj(agm10) that has plenty of pressure for the first 10 seconds, then drops to very low pressure. What am I needing to replace here? Thanks

I have an older Kobalt 10 gal 1.5 HP “KLA1581009”. It gets used on and off. A few years ago the pc board crapped out. I still use it though. I bought a mini regulator for it, but have not installed it.

Is it worth trying to get a newer pump/regulator assembly to replace the digital regulator? Is that even possible seeing that my ac is so much older.

Closest looking regulator/manifold/pump assembly is the LK20175 version.

I need the regulator housing and knob for my Kobalt 20 gal model 0332041. The housing that the knob screws on to is stripped and won’t allow it to regulate when screwing it either way. Attached is a picture. I tried tapping the thread but it’s already too far gone. I can do a jerry rig fix if I have to but would rather fix it properly. Thank you.

I have a Kobalt mode:LK20175/53294. This is a good compressor other than how LOUD it is. This thing will drive you out of the garage! Does Kobalt make a silencer or after market muffler for this beast?

I have an 8-gallon, 1.8 hp, 150 max psi kobalt compressor that is just over 5-years old. It gets light to moderate use. Recently, when filling on start the motor runs normally, but when it fills to 75 psi, it stalls and makes a buzzing sound. I am thinking that it is the run capacitor is going bad? What is the problem?

What would cause my reset button to keep tripping before air builds up??? Bought compressor during black friday 2019 so it fairly new its a 60 gallon kobalt 2 stage compressor

Bought a kobalt 26 gal quiet run compressor in April of 2018. On Dec 31,2019, I went into the garage and found it running continuously. Heard air blowing and thought a line split. Found that a cheap brass fitting had blown the top off. It fits on a 4 way fitting that has the line from cylinders on the left ( as you look at front), the bleed off copper tube on the front, and the line to the tank on the bottom. The cheap peice is located on the right side of the fitting. All you see is the golden wrench acceptable cap.
This cap has a small, thin copper tube that fits into the 4 way fitting. It has fine, external threads. Inside the tube is a spring and small plastic plug that blocks the bleed off tube when the motor is off.
Of course, theres no picture or part # for this cheap copper piece. I jjust spent 35 minutes on the phone with Lowes warranty center. All they could do is send an email to the manufacturer and explain my problem and ask them to get ahold of me. I can’t return it till I hear from the manufacturer. They have the call on if it’ll be eligible for replacement under warranty. I’m told they’ll call or email me in 2-3days but with it being Thursday, it could be next Wednesday before I hear from them.
Next time I’ll go back to Sanborn like my last one. It lasted over 25 years.

I have a Kobalt 30 gallon, model #LLA1683066, and I need the oil level sight glass. The one on there now is cracked and leaks oil. I’ve looked the part number up and it always says the item is obsolete. Any suggestions?

Does kobalt warranty their 3 gallon compressor ?

Need a 60 gal replacement tank for kobalt k7060hfv….exact replacement would be great,having trouble finding one,

I just want to unload! 😉

Hi, love your site I have learned a ton about compressors trying to solve my problem below. Thanks for all your time and effort!

I have a circa 2008 Kobalt 26 gallon, 1.5 hp single stage compressor that my dad gifted me. In the several months I have had it, if I am using it for any high-volume application it will not restart on low tank pressure, rather it makes an angry buzzing/humming noise. Using your web site and diving into the compressor, I have figured out that the cylinder is taking a long time (3-10 minutes or more) to unload. I know this is the case because I cannot manually turn the flywheel when it is loaded but I can when it is unloaded. If I crack a fitting on the tubing between the pump and the tank the cylinder immediately unloads.

I replaced the tank check valve, which eliminated the super long unload times, but it still won’t unload for at least 3 minutes. Also, I cannot detect that it is unloading: there is no hissing, groaning, whooshing or popping. Sometimes the piston will get incrementally easier to move as time goes on, sometimes I can’t move it at all and then 30 seconds later it’s easy to move.

I can find no unloading mechanism. There is no airline into the pressure switch. There is no airline coming off the compressor-to-tank run. There is no pin hole in the NPT-to-tubing brass adapter at the head. I cannot find any “bolt head” with a hole in it like Brandon found in his December 6 comment. I took apart the pump and checked the head, the valve plate, and cylinder for some pin hole or way to unload and found nothing. I checked and cleaned the valves and their mating surfaces, which were a little grimy but appeared to be sealing.

I cannot figure out how the manufacturer intended this to unload! If I could, I would try to return that to its original state. Any ideas?

Otherwise I am ready to create my own pin hole unloader. Would it be unwise to drill into the cylinder wall at the bottom of the piston’s stroke? Advantage would be that the hole would be outside the high-compression zone, meaning no compressed air is being bled off. Disadvantage is that the hole might be tough on the piston ring, which looks like some kind of impregnated fabric, as it goes past the hole twice per stroke. Other options would be to drill into the valve plate on the inlet side or make a groove in an inlet valve seat. I would appreciate any suggestions.

Thanks again for taking the time to respond to us novices.

I’ve had the Kobalt 8 gallon compressor for probably 5 years or so with it only seeing occasional use.

About a year ago, I started noticing that when it’s filling and reaching full tank pressure, I can hear and feel air coming out of a tiny pin hole in what looks like the head of a bolt. When this starts happening, it seems like the pump runs for a long time (up to even a couple of minutes despite having reached more or less full pressure).

At times, it seems that it fills and shuts of normally, perhaps due to heat causing something to finally close up like it should and not leak air.

I also notice that despite storing the compressor at basically full pressure (and no hose attached), when I go to use it days/weeks later, the tank pressure has typically leaked down considerably, to around 50-80 PSI.

I’ll admit I don’t know much about compressors or their terminology but the best I can describe is it’s mounted on the side near the top of the tank, From reading, it sounds like this is the check valve but I’m not sure. All of the check valve pictures I’ve seen don’t show something looking like a bolt with a pin hole in it.

Do my symptoms and description sound like a bad check valve? Is the pin hole bolt something that threads into the end of the check valve but not actually part of what comes with a replacement check valve perhaps?

Need to know where I can get a manifold blue KNOB for this compressor #0332041 purchased at Lowe’s.
Thanks

Need to know where I can get a manifold for this compressor.
Thanks

I have a up half air compressor model #3332643 26 gal. I was getting water thru the line and went to drain the tank. I did NOT unplug the comressor when I did this. During the drain the compressor started to come on due to the pressure drop but then suddenly stopped and threw the breaker. I turned the ompressor switch off and reset breaker. Turn switch and it acts like its going to start up but stops and throws the breaker every time

I need a compressor for this kobalt compressor model # 215921 . Can you offer any assistance with this?

Need a wiring diagram for a kobalt 8 gal compressor.

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 some photos… please let me know.

Thanks.

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 am not sure where to start looking as I said this was lightly used and is possibly 3 – 4 old.

any guidance would be appreciated.
thank you

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

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

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 can give me an idea what I need to do to remedy this problem.

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 small amount of air from the hole in the screw. I’m much more concerned with the over-pressurization and would like your thoughts on a cause for it not shutting off correctly. Thank you.

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 or solutions. Thanks

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

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.

How do inget power cord out of black box

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?

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 else..

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?

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?

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.

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.

I need a manifold part # E101627…..all sites say discontinued. Is there a replacement part #?

Where do I get this part!!

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?

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

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 put it. My question is: Can I run this compressor in the horizontal position or am I going to have to get rid of it and get another horizontal model?

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 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 to send the bad part as I am curious to find out what could cause this.

On 2nd look, it appears the spring was too much pressure on the knob. The knob split from its threaded ring.
So I will need a knob, and any parts other than the spring, such as a needle plunger.
Any ideas where I can look this up?

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 to fix is there a fix or is it just shot and I need to dump it

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 no such part replacement. My owners manual does not list hardly any electrical parts so I had no p/n. plus a wait time of 20 minutes to talk with s rep. I spent the next 2 hours searching your website but, to no availe. I’m very disappointed with Kobalt at this point as I have most always purchased Kobalt for my tool needs thru the years. Now, I will have to go outside of your company to find the part I need because of your insufficiant owners manuel and parts replacement availability.

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?

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?

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 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

I am searching for a check valve for a Kobalt air compressor(20 gal. 1.8hp) model #0332041.

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

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.

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

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 it will come on and run, but after it pressures up and turns off, it will do the same thing trying to come back on. I have had it a few years but it has a fairly low amount of hours used.

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

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 is no longer in service. I have been searching around and it looks like Sanbor is the manufacturer of this unit and Powermate is compatible as well. I need part #047-0101. Any leads on where to get this or should I call it a day?

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 on to build sufficient pressure. Help!

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 parts site. Is there a common regulator I can use our do you know where I can find the part I need

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?

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?

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?

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.

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 air hissing from the line stops. Is the valve not opening, and if not, is there an adjustment inside the switch?
