This is a critical safety control: it senses flame rollout at the burner box and shuts off the gas valve if flames escape the heat exchanger — protecting the cabinet and your home from overheating. A tripped or failed rollout switch will lock the furnace out of heating (no burner ignition). Never bypass this device.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOpen temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eType: manual-reset thermal rollout limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: flame-rollout \/ burner safety cutout\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GMT070-3 furnace burner assembly\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 component, the \u003cstrong\u003eOEM B1370145\u003c\/strong\u003e is strongly recommended — its trip temperature, reset behavior, and terminal placement match Goodman's design exactly. Generic switches with a different trip point or reset type can nuisance-trip or, worse, fail to protect. For a safety control, match the factory part precisely.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — Two spade terminals and one or two mounting screws. Typically a 10–15 minute repair. Shut off gas and power before servicing. Important: if a rollout switch has tripped, find and correct the root cause (blocked heat exchanger, cracked exchanger, or poor venting) before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058157142387,"sku":"GOODMAN-12298","price":4.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-300-f-rollout-limit-switch-for-gmt070-3-b1370145","provider":"National HVAC Parts","version":"1.0","type":"link"}
