Question about Craftsman 3 gal. Air Compressor, 1.5 hp, Horizontal k
Motor starts and pressure gets to 15/20 psi then motor slows down and trips. Motor is new and valve is new. If i take intake tube off tank motor will run, when the tube is attached to the tank is when the problem occurs.
Make sure your pressure switch is set correctly. Check your pressure gauge and make sure it is functioning correctly. Also,seems sometimes if there is any time when there isn't the adequate amount of power demand supplied the motor heats up more causing the thermal protection switches to act a little finicky which in turn shuts it down.Check how many amps the motor is rated compared to the breaker controlling the circuit. Is it a dedicated circuit only for the compressor or are there other things also drawing power from the circuit ?

Does this trip on pressure or is it a breaker tripping? If you took off the intake then there is no pressure build up, thus it wouldn't trip the pressure switch. But would at the same time add a load to the motor. First check and make sure motor is wired properly, then check that pressure switch is wired properly and is adjusted to the right pressure. I don't believe that the intake tube would be clogged, it's a straight hole into the tank. But could be a possibility.
