My window or through the wall air conditioner will not power on. What can I do?

If your air conditioner has been plugged in and it will not power on, please check the following prior to submitting a service request:

  • Verify that the outlet where the unit is plugged in is operational and / or that the circuit breaker has not been tripped.
  • Verify voltage and amperage requirements have been met. Most common voltage ratings for AC units are 115, 125 and 220 volts, and amperage rating can run from 15 to 20 amps. The lower two voltage ratings are common in smaller units, while units with a rating higher than 15,000 BTUs will require a 220-volt circuit. Refer to specifications for your model for additional information.
  • Check the LCDI plug to see if it has been tripped and needs to be reset. Locate and press the RESET button on the plug. If the RESET button fails to function, the power cord must be replaced.

Note: LCDI stands for 'Leakage Current Detection and Interruption' and provides device protection by sensing damage to the power cord to reduce the risk of fire associated with arcing faults. The LCDI plug can be tested for proper function by pressing the TEST button. This should trip the plug and cut the power to the air conditioner. If the plug does not trip and you are able to turn on the unit, then the power cord or plug is faulty and MUST NOT be used. The power supply cord must be replaced if it fails to reset when either the TEST button is pushed, or it cannot be RESET.
