Mounted at the burner box, it's a critical safety device that cuts power to the gas valve if flames roll out of the combustion chamber — protecting against overheating and fire. A tripped or failed rollout switch stops the furnace from firing and must be replaced with the correct temperature-rated part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 300°F (manual reset)\u003c\/li\u003e\n\u003cli\u003eType: Flame rollout \/ high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMV80703BXA and related 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eNormally closed, opens on overtemperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is rated to trip at exactly 300°F, matching the furnace's engineered safety threshold. Because this is a life-safety component, a generic switch with a different trip point or slower response is a genuine hazard.

Important: if the switch tripped, find and correct the root cause (blocked flue, cracked heat exchanger, failing inducer) before returning the furnace to service.
