Mounted on the heat exchanger bulkhead, it continuously monitors supply-air temperature and de-energizes the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. This prevents heat-exchanger damage and unsafe operating conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Auto-reset thermal limit (opens on rise)\u003c\/li\u003e\n\u003cli\u003ePosition: Heat exchanger \/ vestibule mount\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement for AMH80804BXBB\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana genuine part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine 20162904 arrives pre-set to the factory trip and reset temperatures for this specific furnace, so it protects the heat exchanger without causing short-cycling.
