Why my Husky C602H won't turn on?

  Christopher KingJul 27, 2025
  Your Husky air compressor might not be starting due to several reasons: * The tank pressure is too low; the compressor will automatically turn on when pressure drops to the cut-in level. * There's no electrical power; check the wiring inside the pressure switch and terminal box. * A fuse has blown or the circuit breaker has tripped; inspect the fuse/breaker to find out why. * The thermal overload protector is on; turn the air compressor OFF ( O ), wait for it to cool down, depress the red reset button on the motor and then turn the air compressor to AUTO ( I ). * There may be a loss of power or overheating; verify the wiring. Note that long electrical wires could cause power loss. * The pressure switch might be faulty; in this case, replace it.
