DIY steps
- Before starting the repair, unplug the dryer and verify power is off using a non-contact voltage tester. Wear protective gloves and safety glasses. A blown thermal fuse requires an airflow and vent inspection before replacement; never bypass the fuse or operate the dryer until the overheating cause is corrected.
- Locate the thermal fuse, usually found on the back or bottom of the dryer, and take note of the wire connections. Use a screwdriver to remove the screws holding the fuse in place, and gently pull the fuse out of its mounting bracket.
- Use a multimeter to test the thermal fuse for continuity. If the fuse is blown, it will show no continuity. Remove the blown fuse and discard it.
- Install the new thermal fuse, ensuring it is securely fastened with the screws you removed earlier. Reconnect the wires to the new fuse, using wire connectors to secure the connections.
- Reassemble the dryer in the reverse order of how you disassembled it. Plug in the dryer and test it to ensure it is working properly.
- Clean up any debris or mess made during the repair, and dispose of the old thermal fuse responsibly.
