If your Maytag dryer has mysteriously stopped producingheat, a blown thermal fuse may be the cause of your problem. In Whirlpool dryers,thermal fuses are safety switches that are designed to disrupt the flow ofelectricity to your dryer's heating mechanisms once the dryer reaches apredetermined maximum temperature, usually somewhere around 180 degrees F.Thankfully, troubleshooting the thermal fuse in a Maytag dryer is easierthan it sounds.
Instructions And Things You'll Need
- Electrical tape
- Replacement thermal fuse, if necessary
1 Clean out thelint screen in your Maytag clothes dryer. Lint buildup can cause your dryerto overheat, triggering the thermal fuse to disrupt power to your dryer'sheating mechanisms. Take the lint screen out of your Whirlpool dryer and washit in warm water. Dry the screen thoroughly before replacing it.
2 Look behindthe dryer to check its flexible exhaust hose for kinks or obstructions.Disconnect the exhaust hose from the back of your dryer and clean out any lintthat has built up.
3 Go outside andcheck your Maytag dryer's exhaust vent for obstructions. Lint buildup, birdnests or other obstructions in the outside exhaust vent can trigger yourdryer's thermal fuse.
4 Disconnectyour dryer from its power source before attempting to access its thermal fuse.
5 Access the thermal fuse in your Maytag dryer byremoving the back panel. Remove the screws that hold the back panel in placeand it should easily come free.
6 Look betweenthe dryer's blower housing and exhaust to locate its thermal fuse. The thermalfuse in a Whirlpool dryer looks like a white plastic strip that has two wiresconnected to it.
7 Bypass the thermal fuse in your Maytag dryer whileyou perform a quick diagnostic test. Use electrical tape to tape together thetwo wires connected to the thermal fuse. Reassemble your dryer and plug it backin. Set the dryer to a timed heated drying cycle and press "Start."If the dryer produces heat with its thermal fuse bypassed, it means the thermalfuse needs to be replaced.
8 Replace a blown thermal fuse in your Maytag dryer.Disconnect the power and remove the back panel. Remove the electrical tape thatyou used to perform the diagnostic test and disconnect the wires from thethermal fuse. Remove the screws that secure the thermal fuse to the dryer anddiscard the blown fuse. Attach the replacement thermal fuse by replacing andtightening the screws. Attach the wires to the new thermal fuse.
