my husky air compressor wont shut off.
I have bought 2 new pressure switches and my compressor still wont shut off.
When the pressure reaches its normal pressure of 175 lbs the points will open and the unloader valve will start to leak but the compressor keeps on running until I throw the breaker.
The points will stay open until the pressure drops below 135 lbs.
I can restart the compressor anytime, whether the points are open or closed by the breaker. Its like the pressure switch is irrelevant. What could be wrong?
