Dryer Vent Fan Not Working

Start the dryer on a non heated cycle air only and check the air flow coming out of the back vent of the dryer.

Dryer vent fan not working.

Some people use an air blower to do this. This could be caused by a restriction in your exhaust vent duct system to the outside of your home. The culprit here could be a faulty heating element. Use a cotton swab and a bit of rubbing alcohol to clean the contact areas.

Each fan has a built in controller which senses that the dryer is on and allows the dryer booster fan to run. If the dryer heats but the drum doesn t turn check the rubber belt that connects the motor to the drum. The thermal fuse will trip and prevent your dryer from working if it gets too hot. There s not a way to reset the fuse so if this is your problem you ll need to replace the thermal fuse with a new one.

The thermal fuse is generally in a white plastic housing and it s located in the exhaust duct in the back panel of the dryer. I recommend that you move the dryer forward and remove the flexible vent hose on the back of the dryer. Dryer vent booster fan installation and repair well i think it has been all of 3 weeks since i last spoke of dryer vent booster fans but another booster fan had began to cause problems for this homeowner so it appears service was in order. It may be loose or broken and is inexpensive and usually easy to replace.
