  If your Husky Air Compressor won't run, here's what you can check: * Ensure the unit is plugged in. * Check the fuse or breaker in your shop or house. * Reset the shop/house breaker, and determine why it tripped. * Make sure you are using the correct extension cord. Also, if the compressor has reached its automatic shutoff pressure, release some air from the tank until it restarts automatically.

Why does my Husky 671-049 Air Compressor keep tripping the circuit breaker?
- J
  joneserinAug 19, 2025
  If your Husky Air Compressor repeatedly trips the circuit breaker, it could be due to: * Using the incorrect size fuse. * A circuit overload. * The wrong gauge wire or length of extension cord. To resolve this, check for the proper fuse, use a time-delay fuse, disconnect other electrical appliances from the circuit, or operate the compressor on its own branch circuit. Also, check for the proper gauge wire and cord length.

Why does my Husky 671-049 Air Compressor thermal overload protector keep cutting out?
- K
  Kevin NewmanAug 21, 2025
  If the thermal overload protector on your Husky Air Compressor repeatedly cuts out, it may be due to: * Low voltage. * Lack of proper ventilation or a room temperature that is too high. * Using the wrong gauge wire or length of extension cord. You can try moving the compressor to a well-ventilated area and checking the gauge and length of the extension cord. If the voltage is low, call an electrician.
