My Porter/Cable compressor (25 gallon, non-oiless) keeps tripping the circuit breaker when I turn it on. I have a dedicated 12AWG/20A non-GFCI circuit going to it. I took the AC motor into a shop to have it looked over, they checked the caps and they were OK. They replaced an electronic component saying it was faulty. (Diodes maybe? Sorry, I don't have the invoice with me now but can check it later)
It still trips the breaker. I brought the motor back and they replaced the same part again, saying it was bad. Perhaps from re-trying to start it over and over? Still does the same thing after getting it home. This happens with the tank empty, or partially charged, doesn't matter.
If I take the belt off, the motor starts fine. Sometimes if I turn the motor / pump over by hand a few revolutions it will start. (With the belt / load attached)
The pressure relief seems to be working, it hisses when the motor/pump stop running. I've also ruled out the pressure switch by directly connecting the AC cord to the motor.
Anything else I can try? It was last working in my old house, it was in storage for about 2 months during my move. It ran fine on a dedicate 20A circuit at the old house as well.
