  If your Mitsubishi Electric Heat Pump isn't heating or cooling effectively, it could be due to a few reasons. A common cause is reduced airflow from a dirty or clogged filter, so try cleaning the filter. Also, ensure the temperature is properly adjusted. Verify that there's plenty of open space around the outdoor unit and that nothing is blocking the indoor unit's air intake or outlet. Finally, check if any doors or windows have been left open.

  If your Mitsubishi Electric Heat Pump operates without pressing the ON/OFF button, it could be due to several reasons. Check if the on timer is set and, if so, press the ON/OFF button to stop operation. Also, the auto recovery feature from power failures might be enabled; in this case, press the ON/OFF button to stop operation.

  If your Mitsubishi Electric Heat Pump stops before reaching the set room temperature during heating mode, it may be due to frost forming on the outdoor unit when the outdoor temperature is low and the humidity is high. Normal operation should resume after about 10 minutes.

  If the operation lamp near the receiver for the wireless remote controller on the indoor unit of your Mitsubishi Electric Heat Pump is blinking, it indicates that the self-diagnosis function has activated to protect the unit. Turn off the power switch immediately and consult your dealer.
