Attic Fan Repair

All attic fans, by enforced standards and codes, have a thermal fuse. Most are one time fuses wich trip usually when resistance to the motor reaches a peak point. This almost always happens when your motor gets older and needs to be replaced. Resistance occurs and progresses when dirt,dust, grime ect build up on the once freely spinning system. There are some savy folks on the web that get into soldering on a new fuse but at the risk of time, fire and electricution... you'll be better off buying a replace motor and putting your faith in the professionals.
