Safety Tip

Disconnect the power to the dryer. If it has a plug merely remove that from the socket. If it's a hard-wired dryer we need to find the source and disconnect the power to prevent injuries.

Step 1: Remove the Back Panel

Pull the appliance out because all of this repair is going to be done from the back. Using the nut driver, remove all the screws holding the dryer back panel in place.

Step 2: Locate the Thermal Fuse

The fuse is located near the dryer's blower housing. There are two leads going to the thermal fuse. Gently remove the wires by grasping firmly on the female end of the stake on connector and pull it towards you.

Step 3: Remove the Old Fuse

With the leads disconnected, the nut driver is used to remove the screw holding the thermal fuse in place. Most type of these fuses have a tab on one end. A pivoting motion is required to wiggle it out.

Step 4: Install the New Fuse

To install the new fuse slide that open end with the notch, put the screw back in place and reattach the wire terminals.

Step 5: Reattach the Back Panel

The panel must be put back and reattach the nine quarter inch screws before testing out your repair.

Step 6: Test the Dryer

Plug the dryer in and push it it into the approximate space from the wall. Turn on the dryer to make sure it's now operational.
