I have seen many p/c compressors equipped with a thermal fuse attached directly to the field coil of the motor. Others still have both a 20amp fuse and a thermal reset. You can remove the thermal reset and replace with fuse or eliminate. Do however check that the unit is not drawing too many amps indicating the motor my be failing. Good luck with your repair.
SOURCE: press. switch won't shut off motor when reaching cut-out pressure
IF THE SWITCH WILL NOT SHUT IT DOWN ITS NOT WIRED CORRECTLY, THE POINTS IN THE SWITCH ARE WELDED TOGETHER AND WONT RELEASE OR THE LINE UNDER THE SWITCH IS CLOGGED
SOURCE: pressure switch dows not shut off motor when
Pressure switch has gone bad and needs to be replaced. Part runs around $25. Go online and put in model number, pressure switch. You will find companies that sell replacement parts. I had to replace mind, it did the same thing.
Testimonial: "Thanks for help, many appreciated."
SOURCE: Put new switch on compressor and now wont shut off.
the regulator is failing to do its job. make sure you have it set properly. if you did, you will likely need a new one. also remember to drain the compressor every month to prevent rust from moisture build up in the tank. good luck.
