Mounted on the burner box, this critical safety device instantly cuts power to the gas valve if flames roll out of the heat exchanger — a condition typically caused by a cracked heat exchanger, blocked flue, or failing inducer. When it trips, the furnace will not restart until the fault is corrected and the button is manually reset, protecting the home from combustion gases.\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 shutdown\u003c\/li\u003e\n\u003cli\u003eFit: Goodman\/Amana AMH80905CNAC and compatible 80% 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, precise trip temperature and terminal geometry matter.
