Unit Trips Circuit Breaker Off - Portable Air Conditioner

Unit Trips Circuit Breaker Off - Portable Air Conditioner

If the air conditioner powers trips the circuit breaker off, follow the steps below to resolve the issue. For other related power power issues, please visit Power Issues - Room Air Conditioner article.

  1. Power recommendation.

    Portable air condition must be plugged into a grounded 60Hz, 120VAC, outlet protected by a 15amp time delay fuse or circuit breaker.

  2. Install unit on dedicated circuit.

    If the outlet has the correct voltage, but the breaker is tripping and causing the loss of power, we can preform a simple test to see if other devices are powered on the same circuit as your air conditioner.

    • Turn off all other electrical devices in the room besides the air conditioner.

    • If the unit runs fine with other devices turned off, then likely the unit is not on a dedicated circuit breaker.

    • If the unit is NOT on a dedicated circuit breaker, the unit may power on but not run.

      The reason for this is the unit does not require as much power to display the settings, or even run the fan, as it does to turn on and run the compressor. The A/C must be on a dedicated circuit breaker and not share with other outlets.
