Why is there no airflow when starting the heating on my Mitsubishi Heavy Industries SRF35ZJX-S?

If your Mitsubishi Heavy Industries Air Conditioner is not blowing airflow when starting the HEATING operation and the RUN light blinks slowly, it's likely stopped to prevent cold air from blowing until the indoor heat exchanger warms up, which usually takes 2 to 5 minutes.
