What causes compressor protection in GENUINE COMFORT GCDM09KAC2035HTUS5 Air Conditioner?
- T
  Travis ChambersAug 25, 2025
  Compressor protection in your GENUINE COMFORT Air Conditioner is triggered when the compressor operation has been interrupted, initiating a restart protection. Whenever the unit is plugged in, or power has been restored, a random compressor restart will occur. After a power outage, the compressor will restart after approximately 3 minutes. To prevent short cycling, there is a random startup delay of 3 minutes and a minimum compressor run time of 3 minutes.

Ensure that airflow is not restricted. * The temperature setting may not be appropriately set. Adjust it to a lower or higher setting as needed. * Dirty air filters can impede performance. Remove and clean the filters. * If the room is excessively hot or cold when the unit is started, allow sufficient time for the unit to reach the desired temperature. Starting the unit early can help. * An open vent door can affect performance. Ensure the vent door is closed. * The unit may be in a protection or diagnostic failure mode. Check the DIP switch settings. * The compressor might be in a time delay. Wait a...
