This thermal fuse is used in dryers as a safety mechanism that stops the flow of electricity to the motor circuit when a dryer overheats. This replacement part features two 3/16 inch terminals, and is sold individually. When this fuse is faulty, your dryer will not start or it will not heat properly. This is a one-time fuse, meaning it cannot be re-set. It must be replaced when there is no longer continuity between the terminals. It attaches to the blower wheel housing. Blown fuses can be caused by clogged dryer vents. We recommend checking to make sure all of the vents are clear when you perform this repair.
