Mounted near the burner assembly, it detects flame rollout — flames escaping the heat exchanger — and immediately shuts down the furnace to prevent fire and heat-exchanger damage. If your furnace locks out on a repeated safety fault, a tripped or failed rollout switch (often caused by a blocked flue or cracked heat exchanger) is a prime suspect.\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\u003eType:\u003c\/strong\u003e Flame rollout limit switch (manual reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Temperature:\u003c\/strong\u003e 350°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Opens on temperature rise, manual reset button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GSMS100-4 furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370154\u003c\/strong\u003e guarantees the exact 350°F trip point and correct bracket\/terminal layout for the GSMS100-4.
