Why my fan won't blow - Traeger Industries BBQ070 All-in-One Grill / Smoker

To clarify, the compressor and fan will run in defrost mode. The compressor and fan runs to dry out the air blowing onto the windshield.
Now if the condenser fan runs in "heat" you may have a problem with the fan relay or the main controller.

Hi, each fan or blower have switch to work on high and low blowing air. Check your blower switch first.

If you have climate control it could be the main processor. Something could be shorting the blower relay to keep it on. You would also need to check and see if the system is still full of freon.

The fans heat speed is low speed and the cool speed is high speed. High speed is controlled by the fan relay normally open switch, the low speed is controlled by the temperature delay or time delay.

Have you checked the blower motor for power and ground ?

check fuses

If the blower motor runs in the off position, check the fan relay.

check ac control unit if you replaced blower module and if your sure fan works

Sound like you have a failed fan motor assembly. Check for power to the fan motor connector.

Check the 30 amp fuse? don-ohio (:^)
