What to do if my Porter-Cable PXCM301 Air Compressor has low discharge pressure?
- D
  Derrick FrankAug 13, 2025
  If your Porter-Cable Air Compressor has low discharge pressure, there are several potential causes. First, check for air leaks and tighten or replace any leaking fittings or connections, being careful not to overtighten. Another possible cause is a restricted air intake. Clean or replace the air filter element(s) to resolve this. For other causes, such as leaking valves, blown gaskets, or worn piston rings/cylinders, you should contact an authorized service center.

  Paul SandersAug 17, 2025
  Oil in the discharge air of your Porter-Cable Air Compressor can be caused by worn piston rings or a worn cylinder; in that case, you should contact an authorized service center. It can also happen if the air intake is restricted, so clean or replace the air filter element(s). Finally, check if the oil level is too high and reduce it to the proper level if necessary.

  Excessive belt wear on your Porter-Cable Air Compressor can be caused by a pulley that is out of alignment; realign the pulley with the compressor flywheel. It could also be due to improper belt tension, so readjust it. If the pulley wobbles, replace it and check for a damaged crankshaft or flywheel.

What to do if my Porter-Cable PXCM301 won’t start in cold temperatures?
- J
  Julie WillisAug 25, 2025
  If your Porter-Cable Air Compressor won’t start in cold temperatures, it could be due to too much back pressure in the tank; open the petcock when starting the motor. Another reason might be the use of 40W oil in the crankcase; use synthetic blend, nondetergent air compressor oil instead. Finally, the compressor itself might be too cold; move it to a warmer location.

Why does my Porter-Cable Air Compressor trip the circuit breaker?
- B
  Brittany McgrathAug 28, 2025
  Your Porter-Cable Air Compressor might be tripping the circuit breaker due to several reasons. It could be low voltage or motor overload. Ensure your power supply is adequate and the compressor is on a dedicated circuit. If you're using an extension cord, try using the compressor without it. Also, if your circuit is protected by a fuse, use dual element time delay fuses (Buss Fusetron type “T” only). Another cause may be a drive belt that is too tight. Readjust the belt tension. Restricted air passages can also cause this problem, so inspect and replace transfer tubes or the check valve if needed.

How to prevent my Porter-Cable Air Compressor from overheating?
- M
  Michelle MitchellSep 1, 2025
  To prevent your Porter-Cable Air Compressor from overheating, ensure proper ventilation by relocating the compressor to an area with cool, dry, well-circulated air, keeping it at least 12 inches away from the nearest wall. Also, clean all cooling surfaces thoroughly. If there are restricted air passages, replace the transfer tubes and/or unloader.

What to do if my Porter-Cable PXCM301 Air Compressor stalls?
- J
  Jennifer WilliamsSep 4, 2025
  If your Porter-Cable Air Compressor is stalling, it might be due to low voltage to the motor. Make sure the compressor is getting adequate power. Another possible cause is a bad check valve, which would need to be replaced. If the pump is seized, you should contact an authorized service center.

Why is my Porter-Cable PXCM301 pump knocking?
- J
  Jordan BushSep 9, 2025
  A knocking sound in your Porter-Cable Air Compressor pump can be due to a few reasons. The engine pulley or compressor flywheel might be loose; retighten them and check their alignment. Another cause could be a low oil level in the pump crankcase; ensure the oil is always at the proper level. If there's excessive carbon on the valves or top of the piston, contact an authorized service center.
