Mounted on the burner box, it opens the 24V circuit and shuts down the furnace if flames roll out of the heat exchanger — a condition caused by blocked flue, cracked heat exchanger, or poor draft. This is a critical safety device: a tripped or failed rollout switch should never be bypassed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eReset Type: Manual\u003c\/li\u003e\n\u003cli\u003eCircuit: 24V normally-closed\u003c\/li\u003e\n\u003cli\u003eFunction: Flame rollout safety cutoff\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMS81155CNA and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a life-safety component, OEM is strongly recommended.
