This switch guards against flame rollout — a dangerous condition where combustion escapes the heat exchanger. If it senses excess heat at the burner area it opens the circuit and shuts the furnace down, and it will not automatically reset until the button is pressed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F (open on rise)\u003c\/li\u003e\n\u003cli\u003eReset type: manual push-button\u003c\/li\u003e\n\u003cli\u003eFunction: flame rollout safety limit\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4 in. quick-connect\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT070-4 furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a life-safety control, the calibrated 300°F trip point matters. The genuine Goodman switch is factory-set to the specification the furnace was certified with. Generic switches may carry a nominal rating but wider tolerances, which can nuisance-trip or, worse, fail to trip. For safety controls we strongly recommend OEM.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e Two quick-connect wires and one or two mounting screws — typically 10–15 minutes. Shut off gas and power first. If the switch keeps tripping, do not jumper it; diagnose the rollout cause (blocked flue, dirty burners, cracked heat exchanger).\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058157896051,"sku":"GOODMAN-12326","price":4.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-300-f-rollout-switch-for-gmt070-4-b1370145","provider":"National HVAC Parts","version":"1.0","type":"link"}
