Why is there no airflow when starting the heating operation on my Mitsubishi Heavy Industries SRK60ZJX-S?

If there's no airflow when you start the heating operation on your Mitsubishi Heavy Industries Air Conditioner (and the RUN light blinks slowly), it's because the airflow has 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.
