Positioned on the heat exchanger side of the furnace, the primary limit monitors supply-air temperature and cuts power to the gas valve if the furnace overheats — most commonly from restricted airflow caused by a clogged filter, closed registers, or a weak blower. It is the furnace's main line of defense against heat-exchanger damage and fire risk.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 210°F\u003c\/li\u003e\n\u003cli\u003eType: auto-reset primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80453ANAB furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370190\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur OEM limit is calibrated to Goodman's exact 210°F set point and uses the correct insertion depth and bracket for this furnace.
