Mounted at the burner box, this switch trips and shuts off the gas valve if flame rolls out of the heat exchanger — a critical protection against a blocked exchanger or restricted venting. A tripped or failed rollout switch is a no-heat lockout that must be diagnosed and the root cause corrected before reset or replacement.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F (manual reset)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ADS81155CXA gas furnace\u003c\/li\u003e\n\u003cli\u003eType: Normally-closed flame-rollout safety limit\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a life-safety device, so the calibrated 300°F trip point matters. The \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is factory-set to the furnace's rollout spec. Generic switches may carry a different trip temperature or slower response, defeating the protection.
