Dryer Thermal Fuse Replacement – Complete Repair Guide
The dryer thermal fuse is a safety component that prevents the dryer from overheating. If the dryer temperature rises above a safe level, the fuse blows and shuts down the heating system.
A blown thermal fuse is one of the most common causes of dryers running without heat.
How the Thermal Fuse Works
The thermal fuse monitors the temperature inside the dryer. If airflow becomes restricted or the dryer overheats, the fuse permanently disconnects power to the heating system.
Symptoms of a Blown Thermal Fuse
- The dryer runs but produces no heat
- The dryer will not start
- The dryer stops mid-cycle
Most Common Causes
- Clogged dryer vent
- Blocked lint filter
- Restricted airflow
How to Replace the Thermal Fuse
- Disconnect power to the dryer
- Remove the rear panel
- Locate the thermal fuse
- Disconnect the wires
- Install the replacement fuse
Preventing Future Fuse Failures
- Clean the dryer vent regularly
- Remove lint buildup
- Maintain proper airflow
