How to replace a thermal fuse in a gas dryer

Unplug the dryer to disconnect electrical power. Shut off the gas supply to the dryer.

Move the dryer forward and use a 1/4-inch nut driver to remove the screws from the back panel. Remove the back panel from the dryer and set it aside.

Pull the wires off of the thermal fuse. Remove the mounting screw using a 1/4" nut driver. Pull the fuse off of the blower housing.

Position the new fuse and secure it with the screw. Push the wires onto the connection spades on top of the new thermal fuse. It doesn’t matter which wire goes into which terminal on the thermal fuse.

Position the back panel on the back of the dryer. Line up the mounting screw holes. Insert the mounting screws and tighten them firmly.

Plug the dryer into the wall outlet. Turn on the gas supply to the dryer.

To prevent the thermal fuse from blowing again soon, remove the flexible vent in the back of the dryer and clean the inside of the flexible vent hose. Clean the air duct going to the outside of your home with a duct cleaning brush. Vacuum the area to clean up dust.
