Mounted on the heat-exchanger bulkhead, this auto-reset limit monitors supply-air temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger from cracking and preventing unsafe high-temperature operation. It commonly trips due to restricted airflow from a dirty filter, blocked ducts, or a failing blower.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat protection \/ gas valve cutoff\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana AMH80804BNBD and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eMounting: Heat-exchanger \/ vestibule panel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e control is calibrated to the precise cut-out and cut-in temperatures your furnace requires.
