This safety device sits near the burners and cuts power to the gas valve if flame rolls out of the combustion chamber — a serious condition usually caused by a blocked flue, cracked heat exchanger, or restricted airflow. A tripped or failed switch stops the furnace from firing.\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\u003eOEM Part Number:\u003c\/strong\u003e B1370145\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GMT115-5 gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Bimetallic flame-rollout safety cutoff\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a life-safety limit, the trip point must be exact. Our genuine Goodman switch is calibrated to open at the correct 300°F threshold. A generic switch with the wrong rating either nuisance-trips or, worse, fails to cut off during a real rollout event. Never substitute an off-spec safety control. Important: if the original switch tripped, diagnose and fix the root cause before replacing it.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — about 15 minutes. Disconnect power, unplug the two spade terminals, remove the mounting screws, and install the exact-match replacement in the same position. Test furnace operation and confirm the switch stays closed during a normal heat cycle.\u003c\/p\u003e\u003cp\u003eGenuine safety part, fast shipping, from NationalHVACParts.com.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058161041779,"sku":"GOODMAN-12429","price":4.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-rollout-limit-switch-300-f-for-gmt115-5-b1370145","provider":"National HVAC Parts","version":"1.0","type":"link"}
