Is This the Right Part?

Common Symptoms

• Dryer may stop heating when the thermostat opens from excessive temperature.
• A failed-open thermostat can cause a no-heat condition.
• Repeated thermostat opening may be associated with restricted airflow or another overheating condition; replacing the thermostat alone may not correct the underlying cause.

Check Before Replacing

• With power disconnected, inspect the thermostat and its terminals for visible damage, discoloration, or loose connections.
• Verify the replacement against the appliance model and serial number before installation.
• A qualified technician can test thermostat continuity at room temperature and compare the result with the service documentation; do not bypass the thermostat.
