This page is for anyone that has air compressor wiring problems and cannot figure out how to fix it themselves.
It is important that, along with your question you upload a photo or two of the area on the air compressor power supply, ON/OFF switch, pressure switch connections, motor connections or capacitor connections where you are experiencing the problem. Doing so will help others help you.
Not being electricians, we are hesitant to offer specific electrical advice to others ourselves, though with adequate care and concern we have no problem monkeying around with the wires on our own air compressors.
Adequate care means to ensure that the power supply to the air compressor is off until you are ready to test it, and an understanding the air compressor capacitors are simply fast discharge batteries, and if the capacitor on your air compressor has a charge, then you can easily get zapped if you don’t take care.
We will certainly offer compressor wiring advice in general terms, like check to make sure your air compressor is plugged in and the like but cannot dispense specific electrical advice.
We expect that any air compressor wiring problems will be responded to fairly quickly by the host of visitors that visit this site.

If you are speaking of the power cord plug melting, odds are pretty good you’ve got a much greater than normal power draw, and that could be a variety of issues including a short, motor failing, mechanical lock up of the pump stalling the motor etc., though I’m surprised it would melt the plug before a fuse or breaker blew. Not safe to use, that’s for sure.

Hi Travis. We’ve created a new page on the site to help address air compressor wiring problems, and moved your post to there. We were unable to find a photo of the MT30004 air compressor. We did find out that it is made by Campbell Hausfeld, so if you have not contact them for details, it would be a good idea to do so. We can tell you that on the supply side typically the… Read more »
