Mounted near the burner assembly, this normally-closed switch instantly opens the control circuit and shuts off the gas valve if flames roll out of the burner box — a condition usually caused by a blocked flue, cracked heat exchanger, or failed inducer. It is one of the furnace's most important life-safety devices.\u003c\/p\u003e\u003cp\u003eThis switch trips at \u003cstrong\u003e300°F\u003c\/strong\u003e and is matched to the furnace's factory design. Using the correct trip temperature is critical: a mismatched switch can nuisance-trip or, worse, fail to protect against a genuine rollout event.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Rollout limit \/ flame-rollout safety switch\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370145\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (also fits select Amana furnaces)\u003c\/li\u003e\n\u003cli\u003ePrimary application: ADV80703BXA gas furnace\u003c\/li\u003e\n\u003cli\u003eContact configuration: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eFitment: Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a safety-critical control, the exact 300°F trip point and terminal style matter. Generic switches with a different setpoint can compromise burner-box protection or cause repeated lockouts.

Do not bypass a repeatedly tripping switch — diagnose the underlying cause (flue, heat exchanger, inducer). Professional diagnosis is recommended if the switch keeps opening.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057510203763,"sku":"GOODMAN-3403","price":4.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-300-f-rollout-limit-switch-for-adv80703bxa-b1370145","provider":"National HVAC Parts","version":"1.0","type":"link"}
