919.167312 compressor trips breaker when trying to start after sitting over night.

Craftsman 919.167312 compressor will start and refill while using tools, but trips breaker when trying to start after sitting over night. Replaced check valve, switch assembly, valve plate/gaskets, piston ring.

Rob, that's a good one.

So it starts OK when it's warm, but won't start when it's cool from sitting overnight, and even with the tank empty?

Assuming nothing else is drawing power from the circuit in the morning when you try to start the compressor after sitting all night, if this were mine, I'd be checking the start capacitor. Maybe see that page and check it out?

New compressor for you, Janet?

Well used, often used, not used very often?

Anything new about how you've got it plugged in... power bar or extension cord being used?

Recent problem or one the compressor has had all along?

Provide a bit more info as a comment here and I'll see if I can help.

compressor turns off? 30psi?

by Darrick

i just picked up a craftsman 5hp 25gal air compressor 919.165250 it turns on and runs but only builds to 30 psi then bogs down and shuts off and wont turn back on. could this be the run capacitor or the pressure regulator?

A well used compressor, perhaps? Using an extension cord or power bar? Then don't.

It is possible that it is a run capacitor.

If the compressor shuts off at the pressure switch, that is, power stops flowing through the switch indicating that the pressure switch has shut off, then it could be the pressure switch, but I doubt it.

See the troubleshooting section on the sitemap page for links to pages with more info and things to check.

compressor turns off?
by: Paul from Knight Off Road Trailers

If you need to extend the wire length go with an thicker gauge. I tossed the old wire and plug and used the wire from a floor polisher. super thick and heavy duty. Been running it now for 4 years, no problems.

Fix it?

I'm wondering if this was resolved? I just picked up the exact same compressor with the exact same problem.

My compressor only build 40psi

by Dennis
(Georgia)

I have a Craftsman air compressor model no. 919.165570 It only builds 40 psi and shuts off and then comes back on for a few seconds and shuts off again.

What would this be and how do I check the part before replacing?

What this sounds like Dennis is the pressure switch failing.

The switch should turn the compressor on at the normal cut in pressure, then, when the tank pressure reaches the cut out pressure setting, the pressure switch should shut off the power to the motor and stop the compressor.

If the pressure switch is tripping off and stopping the motor before the cut out pressure setting is reached, then to my mind it's the pressure switch.

Check to be sure that the power is off on the motor side of the switch when the compressor stops at 40 PSI. If power is shut off, then the switch has shut off, and it's time for a new switch.
