Mounted on the heat exchanger \/ blower deck, the primary limit monitors supply-air temperature and shuts off the burners if the furnace overheats — typically from restricted airflow (dirty filter, closed vents, failed blower). This auto-reset switch closes again once temperature drops back to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit switch (auto reset)\u003c\/li\u003e\n\u003cli\u003eTrip setpoint: 150°F\u003c\/li\u003e\n\u003cli\u003eTerminals: Quick-connect spade\u003c\/li\u003e\n\u003cli\u003eMount: Bracket \/ snap-disc\u003c\/li\u003e\n\u003cli\u003eFits: AMH80804BXAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM 20162903 switches are calibrated to the exact 150°F trip point specified for this furnace.
