If the window, built-in, or portable air conditioner has stopped working or will not come on:


  • Verify the outlet you have the air conditioner plugged into is working properly. Also, If the plug is not tight in the outlet, it may not make a good connection. If the outlet is not working or the plug is loose in the outlet, we recommend having an electrician check the outlet.  
  • Make sure the breaker in the circuit break box has not tripped.

    • On occasion a power surge can cause the circuit breaker to open and prevent the unit from operating.
    • The air conditioner should be on a dedicated circuit. If there are other products on the same circuit, they could cause the breaker to trip.
  • The plug has a GFI (GFCI) with a Reset button. Unplug the unit from the wall, press the Reset button on the power plug, and plug back in.
