The thermal fuse kit is accessible from the top of the dryer. Disconnect power and using a putty knife, release the two spring clips holding the top cover to the cabinet. Insert the putty knife in the seam between the top cover and the cabinet at about 4 inches from the sides. Lift the top cover when the first spring clip is released while releasing the second clip then lift the top cover to the rear of the dryer.
The high-limit thermostat is located on top of the heater housing at the rear of the dyer. Remove the screw that secures the high-limit thermostat bracket and replace the thermostat.
The thermal fuse is located on the right hand side of the heater housing and is mounted on a bracket. There's a 1/4" hex-head screw that holds both the heating element and thermal fuse brackets. Remove the screw and the thermal fuse bracket can be lifted off.
The thermal fuse bracket has two locating tabs, one at the bottom and the other is half-way up. Lift the bracket to clear the tabs then remove it and replace the thermal fuse. Reinstall the thermal fuse and high-limit thermostat brackets in reverse order of the removal steps. Press down on the top cover against the cabinet to reengage the spring clips.
