This 350°F manual-reset switch monitors the burner area and instantly shuts off the gas valve if flame rolls out of the combustion chamber — protecting the heat exchanger and your home from overheating. If your furnace locks out on ignition or trips repeatedly, a tripped or failed rollout switch is a frequent culprit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1370154\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 350°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Flame rollout limit switch, manual reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e High-temperature burner safety cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMNT120-5D furnace (verify against your unit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to Goodman's exact 350°F trip point and mounting footprint, so it seats correctly and responds at the temperature the furnace was certified for.
