I had the same problem. Replace the motor capacitor. small white cilinder part with two wire plugs conected to it. This will have a single bolt holding it to the frame casing, you will find it under the black plastic shroud that covers the motor. Take it into any electrical or compressor shop and they will check it for you. costs about $35.00.

SOURCE: breaker relay tripping out
If the unloading valve trips , which i think is the safety valve that tells me the compressor is pumping up past its maximum allowed pressure. that black switch should be the overload switch. check the amps of the wires going to the motor while its running and then look at the name plate of the motor to see the maximum amount of amps that the motor is allowed to draw.

It could be a couple of things. To me it sounds like you have a short in the motor or damage to the cylinder and piston. You need special equipment in order to test the armature and field for a short. There may also be damage to the brushes and brush holder. There could also be a problem with the cylinder and piston. The bearing could be bad causing a hard start for the motor. I think it could be the combination of the two problems listed above. You may want to check the pump first and if that is not the problem it is an electrical short in your motor in which case you should buy a new compressor. It will cost more to fix if the motor is damage than to buy a new one. "BER" Beyond Economical Repair.

may have tripped the overload look for a reset button allot of them have the number 15 on the tip of the button try pushing it in and see if it starts or if it is buzzing when you try and turn it on it most likely is the capacitor
