Thermal fuses keep a drier from overheating in the tumbler in the case of a thermostat malfuntion. The thermal fuse breaks at 196 degrees Fahrenheit if the thermostat, which should shut the systemt off at 155 degrees Fahrenheit, is not working. When this happens, you need to replace the thermal fuse.
Replacing a Thermal Fuse in a Maytag
Unplug the drier from the wall outlet. Pull it out from the wall. Unscrew the screw that holds the vent on, and pull the vent off. Locate all screws holding the back panel on. Unscrew all of these screws with the socket wrench.
Locate the thermal fuse, which is normally right next to the blower on the bottom of the drier. The blower connects to the vent that you removed. If it is not here, then it will be on the side panel of the dryer. The thermal fuse is a white strip of plastic with two wires connected to it.
Pull the two wires out of the thermal fuse. Use needle-nose pliers to pull on the locking clip. Be sure to pull the clips and not the wires. They will pop right off.
Remove the thermal fuse from the drier by unscrewing the two screws on each side of it. Use the Phillips screwdriver to remove these screws. Pull it out from the drier
Replace the old thermal fuse with a new thermal fuse. Screw both screws into the sides of the thermal fuse to hold it in place. Reattach the wires where they were located before.
Replace the operating thermostat. This is on the top-left panel right next to the heater element cover. Pull the two wires off of the thermostat with needle-nose pliers. Pull the locking clips, not the wires. Unscrew the screws on the sides of the thermostat, and pull it out. Put your new thermostat in and tighten down the two screws. Reattach the wires to the thermostat.
Place the back panel back onto the drier. Screw in all screws that were removed. Tighten the vent on the back of the drier where it was removed.
