Check the start capacitor tested at 250 and the other at 40. Both read good.

thanks Dwayne

Is this a new compressor issue Dwayne? In other words, it just started happening but wasn’t before when you used this same compressor in the same location with the same outlet?

Its is a new compressor. The old one lock up.


Boy, that must be annoying, having to change all those parts on a new Kobalt compressor.

It were me, I’d probably have taken it back under warranty and asked for another.

Your old air compressor, it was plugged into the same outlet, yes? What was it and what was the HP on that motor?

You see, I’m wondering if the power supply to the outlet – particularly if it is far from the panel – may be compromised a bit.

Sounds like the check valve, but I’m with Bill – if this is the second bad one, get your money back and buy something else.


Kobalt Compressor Tripping

My Kobalt compressor also kicks out constantly. It sometimes will get to the shut off pressure but not usually. I purchased it and since I had another compressor, I didn’t use it for months. It was past warranty before it was other than a trial run when I first got it home. When it shuts off it’s usually not up to pressure and then after reset, it shortly kicks out again…. I should have known better than to buy this brand. Lowes sells some decent but a lot of low quality tools.

Are you getting enough power to it?

No extension cord?

Depending on model, it may have a run cap. Those can be/go bad, and also sometimes become disconnected. Worth some quick checks.

Start by looking at the pages on the troubleshooting page about compressors that are tripping resets.
