Mounted on the heat exchanger bulkhead, this auto-reset high-limit monitors supply-air temperature and shuts off the burners if airflow is lost or the furnace overheats — protecting the heat exchanger from cracking. Symptoms of a failed primary limit include short-cycling on the limit, no heat, or the blower running continuously.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (temperature-sensing)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ loss-of-airflow safety cutout\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana AMH80603ANBD and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM 20162904 controls are matched to this furnace's exact trip temperature and mounting footprint.
