Replacement Parts by Whirlpool. Details:The Dryer Thermal Fuse is located on the blower housing and shuts off the heating element when the dryer overheats. The thermal fuse cannot be reset, so you need to replace it if it has blown. A clogged dryer vent is the most common cause of a blown thermal fuse. If your dryer won’t start or runs but does not heat up, replacing the thermal fuse may resolve these issues. When replacing this part, consider using Whirlpool’s high-quality and easy-to-install dryer thermal fuse kit. This kit includes (1) jumper wire, (3) screws, (2) connectors, installation instructions, (1) hi-limit thermostat, and (1) thermal cut-off. Installing this kit will require basic hand tools, such as a multi-screwdriver, some disassembly of the dryer, and novice repair experience. Before installing the kit, remember to unplug the appliance or shut off the house circuit breaker to ensure safety.
