Positioned on the heat-exchanger bulkhead, this auto-reset switch is the furnace's main overheat protection: if supply-air temperature climbs past the setpoint due to restricted airflow, it shuts off the gas valve to prevent heat-exchanger damage. A furnace that heats briefly then shuts down repeatedly is often tripping this limit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 150°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-limit \/ overheat protection\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370198\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMH80903BXAA furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1370198 is set to the precise 150°F trip point and uses the correct bracket and disc diameter for this cabinet.
