Mounted near the burner assembly, it detects flame rollout — flames escaping the heat exchanger due to blockage or a cracked exchanger — and immediately shuts the furnace down. This is a life-safety component; a tripped or failed rollout switch should always be investigated, not just replaced.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 350°F (open on rise)\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button reset\u003c\/li\u003e\n\u003cli\u003eFunction: Flame rollout safety limit\u003c\/li\u003e\n\u003cli\u003eFit: Goodman\/Amana GSMS080-4 burner assembly\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370154\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman B1370154\u003c\/strong\u003e is set to the precise 350°F trip point and terminal layout your furnace expects. Because this is a combustion-safety device, an exact-rated replacement is strongly recommended — generic switches may offer a similar temperature rating for less, but any variance on a rollout limit is not worth the risk.

IMPORTANT: if the old switch had tripped, diagnose the cause (blocked flue, dirty burners, cracked heat exchanger) before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058181783923,"sku":"GOODMAN-12973","price":10.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-350-f-rollout-limit-switch-for-gsms080-4-b1370154","provider":"National HVAC Parts","version":"1.0","type":"link"}
