This critical safety device mounts on the burner assembly and instantly cuts power to the gas valve if flames roll out of the burner box — a condition caused by a blocked flue, cracked heat exchanger, or restricted combustion air. When it trips, the furnace shuts down until the fault is corrected and the switch is manually reset.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eReset type: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eFunction: Flame rollout safety cutoff\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT070-4A gas furnace\u003c\/li\u003e\n\u003cli\u003eTerminal type: Quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman switch\u003c\/strong\u003e is calibrated to the exact 300°F trip point specified for your furnace's burner geometry. Because this is a life-safety component protecting against carbon monoxide and fire, matching the factory trip temperature is essential — a generic switch with a different rating can nuisance-trip or, worse, fail to protect.
