Common Symptoms
- Dryer does not heat because the thermal cut-off or thermostat has opened.
- Dryer overheats when the high-limit thermostat fails to regulate temperature.
Check Before Replacing
- With power disconnected, test the thermal fuse and thermostat for continuity using an appropriate meter procedure.
- Before replacing a failed kit, inspect the dryer vent for lint buildup or airflow restriction.
Pro Tip
A blown thermal fuse can be caused by restricted dryer airflow; check and clean the vent system before returning the dryer to service.
