This thermally-activated safety control monitors heat-exchanger temperature and opens the circuit to shut off the burners if the furnace overheats — protecting against restricted airflow, dirty filters, or blower failure. A failed limit switch is a common cause of a furnace that short-cycles or won't fire at all.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 20162901\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-limit \/ overheat safety switch\u003c\/li\u003e\n\u003cli\u003eFits: Amana\/Goodman AMH80403ANBD gas furnace\u003c\/li\u003e\n\u003cli\u003eType: Snap-disc automatic-reset thermal limit\u003c\/li\u003e\n\u003cli\u003eMounting: OEM factory bracket fit\u003c\/li\u003e\n\u003cli\u003eGenuine OEM Goodman \/ Amana component\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM 20162901 is calibrated to the exact open\/close temperature setpoint specified for this furnace's heat exchanger.
