* 37296 Circuit breaker tripping

by Rocky

Hello, I have a 26 gallon Kobalt 37296 compressor that kicks on and runs well until it has about 50psi in the tank. Then it trips the circuit breaker.

A moment moment after it kicks out, I can hear a real small "puff" as if something released.

If I reset the circuit breaker, it will run for a few seconds, then trip the breaker again.

It will eventually climb to about 70 psi before it kicks out immediately after resetting.

It is on an isolated circuit, and the only repair I know to have been done in it is a replaced check valve.

Couple possibles...
by: Doug in s.d.ca.

Thanks for the answers. It really helps.

Is the CB in question the one shown on most of the parts lists, but not on the diagram, or is it part of the motor itself?

If it's the external one, and there's no smell or anything coming from the motor, you could carefully bypass the CB and see if it can get to cut-out without any smell or bogging. Or just replace it, if you prefer.

Again, the manual stinks, but it does say it's an induction motor, so I ask if there is one or more capacitors connected to the motor. If so, you'll want to test those, and replace any bad one, before even messing with the CB as above.

Thanks, and good luck.

Also, yes, it holds air after it trips. No pressure valve opening or anything. The only thing I hear is a very small, quick psst of air.

Check valve
by: Rocky

The check valve was replaced, simply because it was thought to be the cause of this issue. Yes, I'm referring to the button style circuit breaker on the machine itself. On the back end of the motor. The unit is plugged directly into the wall. No extension cord.

CB trips

Awful manual for this...

But a bit of background, please.

You refer to the breaker on the machine, which is not shown on the diagram, right?

Was the check valve replaced for a similar problem? If not please tell why.

It now holds air after the breaker trips?

And it's not on a extension cord, or if it is, it's a really heavy one?
