Mounted on the heat exchanger bulkhead, the primary limit continuously monitors supply-air temperature. If airflow is lost or the furnace overheats, the switch opens to shut off the gas valve and burners, then automatically resets once temperatures return to a safe range. It is the furnace's first line of thermal protection.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary auto-reset high-limit switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162901\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003eFits: ADSH801005CXAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (snap-disc)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine 20162901 arrives pre-calibrated to the factory-specified open\/close temperatures with the correct disc diameter and bracket.
