Today the compressor wouldn't kick on like normal when it got down to 80 PSI. I checked the plug, outlet and the breaker and all are fine. The motor doesn't smell burned at all and the pump is not locked up since the pulley turns freely by hand. The switch points are making contact when the power switch is turned on but nothing happens.
Do you think it is the pessure switch relay? I don't know anything about compressors so forgive me if I have the temenology wrong.
Any help would be great.
ARE THE POINTS BURNT IN THE PRESSURE SWITCH? DO YOU HAVE A LEVER ON THE SWITCH SET TO ON OR AUTO? IF YOU THINK ITS THE SWITCH JUST BYPASS IT AND TIE THE WIRES TOGETHER TO SEE IF IT RUNS. BEWARE YOU HAVE NO PRESSURE PROTECTION EXCEPT POP-OFF VALVE. MOST P.O.S. COMPRESSORS LIKE PORTER CABLE HAVE 3500 RPM MOTORS AND HAVE A THERMAL RELEIF BUTTON ON THEM. JUST PUSH TO RESET. MAKE SURE YOUR WIRNG OR DROPCORD IS LARGE ENOUGH GAUGE. SMALL GAUGE DROPCORDS KILL COMPRESSORS.
