Mounted on the heat-exchanger\/plenum, this control continuously monitors supply-air temperature and shuts down the burners if the furnace overheats due to restricted airflow, a dirty filter, or blower failure. Unlike a manual-reset limit, the primary limit typically auto-resets once temperatures return to a safe range, allowing normal operation to resume.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eFunction: De-energizes burners on plenum overheat\u003c\/li\u003e\n\u003cli\u003eMounting: Heat-exchanger \/ supply-air plenum\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman \/ Amana AKSS920905DXAA and related furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e 20162903 is calibrated to Goodman's exact 150°F trip point with the correct probe length and mounting flange for a true drop-in replacement.
