Mounted on the burner bracket, this flame-rollout switch trips and cuts power to the gas valve if flames roll out of the heat exchanger — a dangerous condition usually caused by a cracked heat exchanger, blocked flue, or dirty burners. It is a critical last line of defense against combustion escaping the burner box.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eType: Flame rollout safety switch (manual reset)\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed (opens on rollout heat)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMS80905CXA 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\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e rollout switch is calibrated to trip at the precise 300°F rating and mounts flush to the factory bracket for accurate heat sensing. Because this is a life-safety control, we do not recommend generic substitutes — an incorrect trip point or poor bracket contact can prevent the switch from protecting against flame rollout. Always install genuine OEM.\u003c\/p\u003e\u003ch3\u003eImportant Safety Note\u003c\/h3\u003e\u003cp\u003eA rollout switch that has tripped indicates an underlying combustion problem.
