Reasons Central Pneumatic Air Compressor Keeps Tripping Reset Button

There are a few reasons as to why your reset button may be tripping on your air compressor and these are:

  • Power supply
  • Air compressor runs too long
  • Centrifugal switch

Power Supply

Check to make sure that your air compressor is plugged right into the wall socket, and that it is not being powered through an extension cord or power bar. They may not be large enough to allow the flow of power that the compressor motor needs to operate efficiently.

Air Compressor Runs Too Long

If you are using your air compressor for extended periods, the typical DIY air compressor will overheat. The duty cycle of the compressor may be less than the time you are requiring it to run, and the motor will overheat.

If you believe this is happening to your air compressor, try only running it for ten minutes and then letting it sit for at least the same amount of time so that the motor can cool, before firing it up again.

Centrifugal Switches

The centrifugal switch can stick which will keep the start windings energized tripping the thermal switch. If the centrifugal switch were to get stuck in an open position then the windings won’t shift properly.

The start windings can’t withstand the heat of the compressor’s full RPM which subsequently causes the compressor to overheat and the reset button to trip.

Question

I turn on my air compressor and it will run up to about 25 pounds pop the black reset button on the side of the motor, I wait a few minutes to reset and it will run for about another 10 or 20 pounds, and pop the button again. I have had this for about 5 years and never had this problem before it would pump up to 110 pounds no problem this is a 21-gallon upright compressor.

Response

It sounds like the compressor motor is overheating.

Assuming all is mechanically correct on the compressor, then John, I would look to the run capacitor, or the motor itself failing.

Question

I need to replace the reset switch as the compressor reset switch keeps popping out. I have to reset the switch in order to use the compressor and I feel that this is happening too many times. I can plug it into the wall plug and it still does it.

Response

Vern, does the compressor run for a while before the reset switch pops out, or is it happening on startup?

If the reset switch keeps popping, that suggests to me that the motor is overheating and that it is not the switch that is the problem, but the motor overheating that is causing it.

It would be good if you had included the model number of your compressor, and provided some idea of whether the compressor is new or well used. If well used, you quite likely have other air compressor problems than a reset switch.
