It is a critical safety limit mounted near the burner box that trips and cuts gas to the valve if flame rolls out of the burners — a condition usually caused by a blocked heat exchanger, cracked exchanger, or poor combustion airflow. When this switch opens, the furnace locks out and will not fire until the fault is corrected and the button is reset.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 300°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Manual-reset flame rollout safety limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e Goodman GMV80905CXA (verify against your rating plate)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e OEM factory safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a life-safety component, the OEM B1370145 is calibrated to Goodman's exact 300°F trip point and terminal layout.
