I have a 60-gallon belt-driven compressor that has a Harbor Freight motor and head (both new). Every time the compressor gets up to the desired shut off amount it does so but also trips the reset on the motor. Additionally, I have to turn the breaker off and back on for the motor to restart. I have replaced the pressure switch and the same thing happens. I even switched tanks with the same result. Does anyone have any suggestions on what the problems maybe?
