Why is my Craftsman 921.16472 not building enough pressure?

  If your Craftsman Air Compressor isn't building enough pressure, delivering enough air, or won't stop running, several factors could be at play. First, ensure the tank petcock is closed. Check all fittings with soapy water for leaks, and tighten or reseal them, being careful not to overtighten. Clean or replace the air intake filter if it's restricted. Reduce air usage if it's excessive. Verify that the compressor meets the air requirements of your accessories; a larger compressor may be necessary. Inspect the air hose for holes and replace if needed. If the tank is leaking, immediately replace it and do not attempt repairs. For blown seals, valve leaks, or a leaking/worn piston, contact a qualified service center.

Why does the pressure gauge drop when using my Craftsman Air Compressor?
- G
  Gabriella DelacruzAug 9, 2025
  A drop in the regulated pressure gauge reading on your Craftsman Air Compressor when using an air accessory can be normal. If the pressure drops too low, adjust the regulator while the accessory is in use. However, if the drop is significant, it might indicate that the compressor isn't large enough for the accessory. Check the air requirements of the accessory and compare it to the compressor's CFM and pressure output. You may need a larger compressor.

  If the pressure relief valve on your Craftsman Air Compressor opens, it means the tank pressure has exceeded the normal operating pressure, or the pressure switch is stuck. Contact a qualified service center.

What to do if my Craftsman 921.16472 motor will not run?

  If the motor on your Craftsman Air Compressor won't start, it could be due to several reasons. If the tank pressure is already at the preset limit, the motor will start automatically when the pressure drops. If the motor overload protection has tripped, allow the motor to cool down so the overload switch can reset automatically (this may take several minutes). Check the fuse or circuit breaker and replace or reset it, ensuring you don't use a higher rating than specified. Check for a proper 'Fusetron' type T fuse, low voltage, and the correct extension cord size. Try disconnecting other appliances and operating the compressor on its own dedicated circuit. Clean or replace a dirty or defective check valve. Make sure the cord has the correct wire gauge and length. For loose electrical connec...
