Mounted on the heat-exchanger bulkhead, it continuously senses supply-air temperature and opens the gas valve circuit if the furnace overheats due to restricted airflow, a dirty filter, or blower failure.\u003c\/p\u003e\u003cp\u003eThis is the furnace's primary over-temperature safety. A failed or out-of-calibration primary limit is a leading cause of short-cycling on heat and no-heat lockouts. Installing the correct OEM control restores the exact trip and reset points your control board's ignition sequence relies on.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic (self-resetting on cooldown)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Heat-exchanger over-temperature protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS81005CXAC and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The primary limit's trip temperature and mounting geometry are model-specific. Genuine Goodman OEM controls are calibrated to your furnace's design airflow and heat rise; a generic limit with a different setpoint can cause nuisance trips or, worse, fail to protect the heat exchanger.
