The flame rollout switch is a manual-reset thermal cutoff that shuts off the gas valve if flames roll out of the burner box — a key safety device that protects against a blocked heat exchanger or restricted flue. If your furnace locks out and the switch has tripped, it usually indicates an underlying combustion or venting problem that should be inspected.\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\u003eType: Manual-reset flame rollout limit switch\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GMT070-3A gas furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003eOEM\u003c\/strong\u003e switch is calibrated to the exact 300°F trip point and mounting\/terminal spec your furnace requires.
