• Protects the heating system by interrupting power when temperatures exceed its rated limit
• Helps maintain consistent operation when the original thermostat is stuck open/closed or out of calibration
• Typical symptoms: no heat or intermittent heat, overheating/safety shutdowns, or failed continuity when tested cool

• 1 thermostat

• Disconnect power (and shut off gas supply if applicable) before servicing
• Note wire locations and transfer one at a time to the new thermostat
• Mount securely in the original position to ensure proper temperature sensing
• After installation, run a test cycle and monitor operation/temperature

• Disconnect power before servicing; microwaves contain a high-voltage capacitor that can retain a dangerous charge
• Access is typically behind the top grille/control area; note sensor orientation before removal
• Handle the sensor by its body; avoid contaminating the sensing face
• Route wiring as original and ensure the connector is fully seated before reassembly

This outlet backup thermostat for dryers mounts on the exhaust duct and provides secondary over-temperature protection. It shuts the heater off if exhaust air gets too hot, helping maintain safe, consistent drying.

• Serves as a secondary temperature limit on the exhaust/outlet duct
