Why doesn't the indoor fan start up during heating in my Gree Air Conditioner?
The indoor unit (IDU) fan might not start immediately during heating for two reasons: initially, it waits for the heat exchange to become hot to prevent delivering cool air; during defrosting, it stops because the system switches to cooling mode, also to prevent delivering cool air. Allow the fan to resume operation after defrosting, or wait for the heat exchange to become hot.
