What to do if my Porter-Cable Air Compressor motor will not run?
If the motor of your Porter-Cable Air Compressor won't start, let it cool down to allow the overload switch to reset automatically. Ensure the tank pressure is below the pressure switch's cut-in point, so the motor starts automatically. Inspect and clean or replace the check valve if it's stuck. Check the wiring connections inside the pressure switch and terminal box. Avoid operating the compressor in a paint spray area. Bleed the line by pushing the lever on the pressure switch to the 'off' position; if it doesn't open, replace the switch. Check the fuse box, replace blown fuses, and reset the circuit breaker, using the correct time-delay fuse and rating. Rule out low voltage conditions and extension cord issues, and disconnect other appliances or use a dedicated circuit.
