Mounted on the heat exchanger bulkhead, this limit senses supply-air temperature and shuts down the burners if the furnace overheats — typically from restricted airflow such as a dirty filter, closed registers, or a failing blower. It is an essential automatic-reset safety component that prevents heat exchanger damage and cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Supply-air over-temperature cutoff\u003c\/li\u003e\n\u003cli\u003eMounting: Heat exchanger \/ blower bulkhead\u003c\/li\u003e\n\u003cli\u003eFits model: AMS950904CXAB (and cross-compatible Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM\u003c\/strong\u003e control is factory-calibrated to the exact trip temperature Goodman specifies for the AMS9 heat exchanger.
