This normally-closed thermal switch opens at approximately 150°F to shut down the burners if the heat exchanger overheats, protecting your furnace, ductwork, and home from unsafe operating temperatures. A failed or drifting limit switch is a common cause of intermittent lockouts, short cycling, and no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 20162903\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eOpen temperature: 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003eContact type: Normally closed (SPST)\u003c\/li\u003e\n\u003cli\u003eBrand fit: Goodman \/ Amana furnaces\u003c\/li\u003e\n\u003cli\u003ePrimary model: AMVC80704BXAA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the exact trip temperature and mounting footprint the control board expects, ensuring reliable safety response and correct staging. Aftermarket generics may open at slightly different temperatures or use looser tolerances, risking nuisance trips or delayed shutdown. For a factory-matched fit and full furnace-board compatibility, we recommend the genuine OEM part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5).\u003c\/strong\u003e Replacement is typically a two-wire, single-fastener swap on the burner\/heat-exchanger assembly. Always disconnect power at the furnace switch and breaker before servicing. If your furnace repeatedly trips on limit, also inspect the blower, filter, and airflow — a chronically open limit is often a symptom of restricted airflow, not a bad switch.\u003c\/p\u003e\u003cp\u003eBacked by genuine OEM quality for dependable, safe furnace heating all season long.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057861837171,"sku":"GOODMAN-8220","price":19.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-150-f-primary-limit-switch-for-amvc80704bxaa-20162903","provider":"National HVAC Parts","version":"1.0","type":"link"}
