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.
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.
The fantech controller cycles the fan at 10 minute intervals until the dryer has stopped and the timer delay has expired.
An effective maintenance program for your dryer vent includes regularly removing it from both the dryer and the capped opening and clearing out the lint.
I recommend that you move the dryer forward and remove the flexible vent hose on the back of the dryer.
Each fan has a built in controller which senses that the dryer is on and allows the dryer booster fan to run.
The thermal fuse will trip and prevent your dryer from working if it gets too hot.
Some people use an air blower to do this.
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.
If the dryer heats but the drum doesn t turn check the rubber belt that connects the motor to the drum.
It may be loose or broken and is inexpensive and usually easy to replace.
The culprit here could be a faulty heating element.
Use a cotton swab and a bit of rubbing alcohol to clean the contact areas.
