How to Change a Dryer Thermal Fuse


Thermal fuses have one duty, and that is to prevent the dryer from overheating. If the dryer does start to overheat then the thermal fuse breaks its connection to stop electricity from flowing to the motor. If the dryer turns on but does not heat up, the problem could be a thermal fuse.

Things You'll Need

  • Flat head screwdriver
  • Needle nose pliers
  • Unplug the dryer from the wall outlet. Pull the dryer away from the wall and remove the vent from the back of the dryer. Loosen the clamp on the vent by unscrewing the screw that holds the clamp with a flat head screwdriver. Remove all screws holding the back panel on. Pull the panel off.

  • Locate the thermal fuse. It is generally to the top right of the blower. If it is not there, it will be on the side panel of the dryer. It is basically a white strip with two wires running 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 when you use the needle nose pliers.

  • Unscrew the two screws that hold the thermal fuse in place with a flat head screwdriver. Use the screwdriver to pry off the thermal fuse.

  • Put the new thermal fuse where the old one was. Screw in the two screws that hold the thermal fuse in place. Reattach the two wires to their designated slots. Refer to manufacturer's manual for wire placement.

  • Place the back panel back onto the dryer. Screw in all screws that were removed. Tighten the vent on the back of the dryer from where it was removed.
