Mounted on the heat exchanger housing, this normally-closed thermal switch opens at its 150°F trip point to cut the gas valve and protect against overheating from restricted airflow, a failed blower, or a dirty filter. It's a core safety device — the furnace will lock out or fail to fire if this switch is open or faulty.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 150°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit, auto-reset, normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMEC800603BXAB and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overheat \/ airflow-loss protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Limit \/ safety switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine 20162903 is calibrated to the exact 150°F set point and physical bracket for this cabinet.
