Mounted on the heat exchanger\/burner bulkhead, it monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger from cracking and preventing a fire hazard. If your furnace short-cycles on the limit, overheats, or won't fire, a failed primary limit is a common cause.\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: Overheat safety cutout for burner circuit\u003c\/li\u003e\n\u003cli\u003eCompatible model: AMH950904CXAA\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana (Daikin family)\u003c\/li\u003e\n\u003cli\u003eMounting: Bulkhead flange-mount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162904 is calibrated to the exact trip and reset temperatures Goodman engineered for this furnace's airflow and heat exchanger. Universal or substitute limits with the wrong setpoint or flange can trip prematurely, fail to protect the unit, or not seat correctly.
