This manual-reset safety control mounts near the burner box and instantly cuts power to the gas valve if flame rolls out of the heat exchanger — a serious hazard usually caused by a blocked flue, cracked heat exchanger, or restricted combustion air. If your furnace locks out and the rollout switch has tripped, the underlying cause must be corrected before resetting.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFits: Goodman GMT135-5 furnace\u003c\/li\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 limit\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370145\u003c\/li\u003e\n\u003cli\u003eTwo-terminal, normally-closed contacts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eSafety limits must trip at their exact rated temperature.
