Why is my Mitsubishi Electric PCH-2GKHA Air Conditioner not cooling or heating well?
- D
  davidroweAug 11, 2025
  If your Mitsubishi Electric Air Conditioner isn't cooling or heating the room well, there might be several reasons: * The temperature setting might be incorrect. Check the remote controller's set temperature against the actual room temperature and adjust using the COOLER and WARMER buttons. * Clogged filters can restrict airflow. Clean the filters to allow proper operation. * Obstructions blocking the outdoor unit's intake or outlet. Clear any obstructions. * An open door or window. Ensure all doors and windows are closed.

  If your Mitsubishi Electric Air Conditioner won't start, check the following: * Ensure the main power switch is turned on, and then press the POWER ON/OFF button. * Check if the main power fuse has blown and replace it if necessary. * See if the outdoor unit’s ground fault breaker is open and reset it. * If there was a power cut, wait for the power to be restored and then press the POWER ON/OFF button.
