  If your Mitsubishi Heavy Industries Air Conditioner isn't cooling or heating properly, make sure you've set the thermostat to a suitable temperature. Also, check if the air filter is clean and not clogged. Ensure that all doors and windows are closed, there's no direct sunlight entering the room, no heat sources present, and that the room isn't overcrowded.

  If your Mitsubishi Heavy Industries Air Conditioner doesn't restart immediately after being stopped but the RUN light is on, it's because the restart function is blocked for 3 minutes to protect the unit. The microcomputer's three-minute protection timer will automatically restart it.

What to do if my Mitsubishi Heavy Industries DXK15Z5L-S Air Conditioner airflow is not blown out when starting the HEATING operation?
- T
  Thomas EvansAug 28, 2025
  If your Mitsubishi Heavy Industries Air Conditioner isn't blowing air when starting the HEATING operation, but the RUN light blinks slowly (1.5 sec ON, 0.5 sec OFF), it's because the airflow is stopped to prevent cold air from blowing out until the indoor heat exchanger warms up. This may take 2 to 5 minutes due to the HOT KEEP program.

  If your Mitsubishi Heavy Industries Air Conditioner airflow is not blown out for 5 to 15 minutes, or blows not warm wind for a moment during HEATING, and the RUN light blinks slowly (1.5 sec ON, 0.5 sec OFF), the unit may be defrosting automatically due to low outdoor temperature and high humidity. Please wait for it to complete.
