This is a safety-critical limit control mounted near the burner box: if flames roll out of the burners — usually from a blocked heat exchanger, cracked flue, or restricted venting — the switch opens at 300°F and shuts down the gas valve to prevent fire and overheating. A tripped or failed rollout switch is a common cause of a furnace that ignites briefly then locks out.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F (open on rise)\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button reset\u003c\/li\u003e\n\u003cli\u003eFunction: Flame rollout \/ high-limit safety cutout\u003c\/li\u003e\n\u003cli\u003eCompatible model: Goodman GUI100-3 furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370108\u003c\/li\u003e\n\u003cli\u003eNormally-closed, opens on over-temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a \u003cstrong\u003esafety device\u003c\/strong\u003e, the exact OEM trip temperature and terminal configuration matter.
