Mounted on the heat-exchanger \/ blower bulkhead, it continuously monitors supply-air temperature and opens the burner circuit if the furnace overheats — typically from a dirty filter, blocked ductwork, or a failed blower motor. A failed limit control is a common cause of a furnace that lights then shuts off (short-cycling) on a high-limit lockout.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Automatic-reset primary high-limit control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Over-temperature burner cutout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment Type:\u003c\/strong\u003e Gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e ACVC960804CNAA and related ACVC96 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM \u003cstrong\u003e20162904\u003c\/strong\u003e is calibrated to the exact trip and reset temperatures specified for this heat exchanger.
