• Helps prevent overheating; supports stable, repeatable heat cycling
• Common failure symptoms include no heat, overheating/shutting off too soon, or longer-than-normal run times
• Electrical component—failure may be intermittent before complete loss of function

• Disconnect power (and gas supply, if applicable) before service
• Note wire locations; transfer connectors one at a time to the new thermostat
• Mount firmly against the mating surface for accurate temperature sensing
• After installation, verify proper operation and temperature cycling
