Mounted on the heat exchanger partition, this 210°F primary limit is the furnace's main overheat protection — it opens the burner circuit when supply-air temperature climbs too high due to restricted airflow, a dirty filter, or blower failure, preventing heat-exchanger damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 210°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type:\u003c\/strong\u003e Automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Primary high-limit \/ heat-exchanger overtemp protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMS80453ANAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e B1370190\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This genuine Goodman OEM limit is calibrated to the exact 210°F cut-out and matched to the furnace's mounting flange and insertion depth. Generic switches with different trip points or probe lengths can cause repeated lockouts or fail to protect the heat exchanger. For the furnace's primary safety, OEM is the correct choice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall Difficulty:\u003c\/strong\u003e Easy (1\/5). Kill power, remove the two mounting screws, transfer the spade wires to the new switch, and reinstall on the partition panel. Replacement typically takes 10–15 minutes. Verify a full heat cycle completes without a limit trip.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057684431219,"sku":"GOODMAN-6757","price":10.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-210f-primary-limit-switch-for-ams80453anaa-b1370190","provider":"National HVAC Parts","version":"1.0","type":"link"}
