Thermal fuse for your model (buy two, they’re cheap)

Step by step

1 Find it

Open the lower front or rear panel. The fuse is a small white/silver oval with two wires, mounted on the blower housing or heater can depending on the model.
2 Test it

Pull one wire and check continuity across the fuse. Open = blown. (Room temperature, dryer unplugged.)
3 Swap it

One screw, two spade terminals. The wires can go on either terminal on most fuses.
4 Fix WHY it blew

A thermal fuse never blows for no reason. Vacuum the blower housing, check the blower wheel for lint packing, and clean the entire vent run to the outside, otherwise your new fuse is on a countdown.
5 Test

Reassemble and run a full cycle, confirming strong airflow at the outside flap while it runs.

🔧 WHEN TO CALL A PRO

Second blown fuse in a year = your airflow problem is beyond a quick clean (crushed in wall duct, roof vent, or a failing blower). A pro with a rotary rig sorts that faster than parts ever will. If you'd rather skip it entirely, find a dryer repair pro near you
