    Why my California Air Tools Air Compressor stopped and does not start?

      Brittany LewisAug 18, 2025
      If your California Air Tools Air Compressor has stopped and won't restart, it could be due to the overload cutout being activated because the motor overheated. Ensure the main voltage matches the specifications. A thin or long extension cord might cause a voltage drop, leading to overheating. Let the motor cool down, then press the Reset button to restart the compressor. Plug the compressor into a socket close to the consumer unit or fuse box. If the motor windings are burned out, contact Customer Support.

      If your California Air Tools Air Compressor doesn't seem to provide as much air as it used to, or cuts off quickly, it could be due to a couple of reasons. One reason is that the tank is full of water due to condensation. To resolve this, open the ball valve to release the pressure, then open the drain valve to release the water from the tank. The pressure switch may also need adjusting, in which case you should stop the compressor and contact the dealer.

To address this, let the compressor build pressure in the tank, ideally to the maximum. Apply soapy water to the air connections and watch for air bubbles. Tighten any leaky connections. If the issue continues, it is advisable to contact the seller for further assistance.

    What to do if the solenoid valve leaks when my California Air Tools Air Compressor is idle?
    • K
      Kathryn WilsonSep 12, 2025
      If the solenoid valve in your California Air Tools Air Compressor leaks when the compressor is idle, the non-return valve seal is likely defective. To fix this, let the air in the tank flow out until all the pressure is released. Then, remove the non-return valve plug and clean the valve seal. If necessary, replace the seal and reinstall all components.
