Why has my California Air Tools Air Compressor stopped and won't start?
- E
  Evelyn PierceJul 29, 2025
  If your California Air Tools Air Compressor has stopped and won't restart, it could be due to motor overheating. Ensure your main voltage matches the specifications. Long or thin extension cords can cause voltage drops and overheating. Let the motor cool down, use heavy-duty extension cords, and plug the compressor into a socket close to the consumer unit or fuse box. Alternatively, burned-out motor windings could be the cause, in which case you should contact Customer Support.

Why does the motor on my California Air Tools SP-9421 not start or start slowly?

  Erica FischerAug 4, 2025
  If the motor on your California Air Tools Air Compressor doesn't start or starts slowly, it might be due to a low voltage supply. Check that the main voltage corresponds to specifications. An extension cord that is too thin or too long can cause a voltage drop and cause the motor to overheat. Allow the motor to cool down. Use heavy duty extension cords and ensure that the compressor is plugged into a socket as close as possible to the consumer unit or fuse box.
