Champion compressor runs only when you hold the RESET button
Champion Air Compressor
Hi, I have a Champion compressor advantage series. All of the sudden the compressor will not start,
It was found that they did not drain for a while. So we opened the valve and lot of water came out.
After that we power the compressor and it will not start. It will start only when you hold the RESET button. If you release the RESET button, it will stop, Please advice
You are powering the compressor with a 240 volt feed I expect, though I don't know if yours is the 5 HP or the greater HP compressor.
The reset button is often a thermal cut out, shutting power to the motor if it starts to overheat. If the motor is cool, and you have to press down on the switch for the compressor to run, it may be that the thermal overload switch itself has failed. If the motor is hot and you continue to over-ride the thermal cut out, then you will likely be damaging your compressor motor.
Does the same symptom occur if you try to start the air compressor with the tank empty of air?
