Mounted near the burner assembly, this manual-reset switch monitors for flame rollout — a dangerous condition where flames escape the combustion chamber — and shuts down the gas valve the instant temperatures exceed its trip point, protecting your equipment and home.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 300°F (manual reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally closed, opens on temperature rise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bracket-mount, burner box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana GMNT045-3B and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e B1370145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM B1370145 is calibrated to Goodman's exact 300°F trip specification and carries the correct bracket geometry for a bolt-in fit. Generic aftermarket rollout switches often ship with a universal bracket and looser calibration tolerances, which can cause nuisance trips or delayed shutdowns. For a critical safety component, we recommend the OEM part for reliable protection and full furnace-warranty compliance.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Easy (1\/5).\u003c\/strong\u003e Replacement takes about 10–15 minutes with basic hand tools. Shut off power and gas, remove the two spade connectors, unbolt the switch, install the new unit, and reconnect. No special calibration required. If your furnace is locking out on a rollout fault, always inspect the heat exchanger and flue for the underlying cause before replacing the switch.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058127815027,"sku":"GOODMAN-11625","price":19.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-300-f-rollout-limit-switch-for-gmnt045-3b-b1370145","provider":"National HVAC Parts","version":"1.0","type":"link"}
