Mounted on the burner assembly, this manual-reset safety device instantly cuts power to the gas valve if flames roll out of the burner box — a dangerous condition usually caused by a blocked heat exchanger, poor venting, or a failing inducer. When it trips, the furnace will not restart until the fault is corrected and the button is reset.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F (opens on rise)\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\u003eTerminals: 1\/4in quick-connect spade\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMS80703ANA and select 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a life-safety component, the genuine Goodman switch is calibrated and UL-listed to the exact trip point and mounting footprint the furnace was certified with.
