This manual-reset switch monitors the burner area and instantly cuts power to the gas valve if flames roll out of the combustion chamber — a critical safety response to a blocked heat exchanger, cracked flue, or restricted venting. A tripped or failed rollout switch will prevent the furnace from firing until the underlying cause is corrected and the switch is reset or replaced.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1370108\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 300°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual-reset flame rollout safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Gas furnace burner safety limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GUI100-4 and compatible models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a \u003cstrong\u003esafety-critical component\u003c\/strong\u003e, we strongly recommend the \u003cstrong\u003egenuine Goodman OEM switch\u003c\/strong\u003e. It is calibrated to trip at the exact 300°F set point your furnace was engineered for. Generic switches can vary in trip temperature and reset behavior, which can either nuisance-trip or, worse, fail to protect against a genuine rollout condition.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — Typically a two-wire, two-screw replacement on the burner bracket.
