When heat on settings are fan-Auto System: Auto, heat, or EmHeat Fan never stops.
If you have the fan on auto and heat to off, the fan should turn off. If it continues to run, you could have a bad thermostat or combustion box fan control
Hello Donna,
You are right. The Auto setting will allow the fan to shut off when the fan is no longer needed.

Here is a link that will have wiring diagram it is for a similar model hunter. Also check your dip switch on the back of the stat to ensure it is set for gas (HG) or electric heat (HE) depending on your type of unit. Good Luck. Rule of thumb for most four wire systems is RED (power to stat) Yellow (Cooling) Green (Fan) White (heat)

The fans are set to delay for 60-90 seconds to remove all heat from the heat exchanger/heater elements.
If the fan runs any longer than 3-4 minutes after the Emergency Heat shuts off, you may have a bad sequencing relay in the air handler.
