Mounted on the heat-exchanger bulkhead, this primary limit continuously monitors supply-air temperature and interrupts the gas valve if the furnace overheats — typically from restricted airflow, a failing blower, or a clogged filter. It is the furnace's main line of overtemp protection and is an auto-reset (snap-disc) style control.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (snap-disc)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens gas circuit on high supply-air temp\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH81005CXBA and related furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e ships with the exact cut-out\/cut-in temperatures and mounting bracket your furnace was engineered around.
