Give the company a call. When my pressure washer smoked I call them and they replaced if for free. Heres there number. the most they can do is say no 1-800-330-0712

Fre would be nice....Its 10 years old...

UNPLUG it and spin everything by hand. Make sure compressor pump is not locked up- often the result of stopping compressor mid-cycle with the pump cylinder fully charged. Electric motor doesn't have the torque to spin it over the compression stroke and pops the breaker. Bleed it down and see if she'll spin,,,,

The video isn't the clearest, but it sounds like the compressor starts, pumps OK, comes up to speed, then immediately shuts down. Usually, with a malfunctioning unloader or with the compressor otherwise locked up, she'll just hum for a few seconds and shut off without ever pumping a stroke.

Empty all the air out of the system and try spinning it by hand. If it spins freely, try it again on electric power. If it still shuts down, I suspect a short inside the motor -- maybe the centrifugal switch or the run capacitor. It sounds like it's tripping the breaker right at the point where the motor should be transitioning from start to run.

You might consider trying another circuit. Circuit breakers can get "weak" after tripping a certain number of times. Also, don't try to run the compressor with an extension cord.

I'd suspect that the starter windings are not disengaging properly. There is a switch inside many of these motors that engage and disengage different sets of windings depending on motor rpm. Sometimes one of the flyweights will jam, preventing the switch from operating correctly.

Other than that, check all motor capacitors, discharge lines, check valve, and unloader systems. If the check valve isn't opening properly, the pump and discharge lines will come up to pressure very quickly, but there is no signal from the tank for the pressure switch to shut off the motor.

Tried more then one circuit. Has to caps. One the needle goes up and stay up...The other cap stays a 0...

If you are checking caps correctly, you got a bad one. Have you got one end disconnected? If they are pretty good size like 50 or 100 MFD, on an ohmeter higher scale you should see needle swing low when ohmeter batt is charging cap and rise to 20K or so when charged. Reverse the leads and it should do same again. I am referring to old time analog meter like Simpson 43 or Vacuum tube voltmeter. Other meters can't helpyou.

Analog VM...I had both wire removed from the cap.
