1.Check the motor first. You can readily see if it's
burned or not. Run a megger test on the motor.
Test run the motor without the compressor.
2. If, it does not run, have it checked at the motor
3. Once it is okey, remount the motor, and start it up.

Sure the outlet you plugged into is working, do not use an extension cord.
If there is power, then there is a black box, where the cord enters the unit., in here is the pressure switch, it tells the unit to work,
unplug the unit open it and see if the plate with the spring moves freely
and then try it again, if not you probably need a new one, I would contact
the company and see if there are problems with the unit and see what they will do for repair, or they might have a better option for troubleshooting this unit.

Could be the return valve. Its the small fitting that attaches to the top tank. Unscrew the top nut its about 11/16's, with no pressure in the tank, and make sure the black rubber seat inside slides in and out of the spring loaded cap, easily. If not, sand the rubber until it does slide easily, then apply light oil, to the area you just sanded and re- assemble.

of course comparative cost buying and repairing make a cost reduction.if your compressor run smooth but tripping,make sure where on the right path of diagnosing of your compressor,we can check if the motor or compressor is shutting off the unit.disconnect the belt from pulley of the motor to compressor,run the motor if still tripping w/o load its better if you have calmp ammeter test,to check the current rating,if it is tripping motor is deffective replace the bearing.f motor is fine sr till tripping check the compressor also the crankcase bearing,replace worn out bearing.have a nice day dont forget to fix my rate.thanks a lot.
