This normally-closed thermal safety control opens at approximately \u003cstrong\u003e120°F\u003c\/strong\u003e to protect the heat exchanger and blower compartment from overheating, shutting down the burners if airflow is restricted or a blower fault occurs.

Generic universal limits often require bending brackets or splicing leads and may trip at the wrong temperature, causing nuisance lockouts.
