- A blown fuse indicates an overheating event. This is often caused by restricted airflow from a clogged vent line.
- Confirm the old fuse has failed by testing for electrical continuity with a multimeter; a blown fuse will show an open circuit.
Installation Tips
- Disconnect the dryer from its power source and gas supply before beginning any repair.
- Thoroughly clean the dryer's lint screen, trap, and entire exhaust vent ducting to the outside to resolve the underlying cause of overheating.
- This part is not resettable. If it blows, it must be replaced.
