Mounted on the burner assembly, it detects dangerous flame rollout — flames escaping the combustion chamber due to a blocked flue, cracked heat exchanger, or poor combustion airflow — and instantly de-energizes the gas valve to prevent fire and carbon-monoxide hazards. This is one of the most important safety devices in the furnace.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1370145\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Flame rollout limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 300°F (manual reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e Goodman GDT070-3B furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Combustion rollout \/ gas-valve cutout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a genuine \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e rollout switch matched to the 300°F trip point and manual-reset design your furnace requires.
