The B1370154 is a genuine OEM flame rollout safety switch for the Goodman GMPE125-5 gas furnace. Positioned near the burner assembly, it senses flame or heat spilling out of the combustion chamber — a symptom of a blocked heat exchanger, cracked exchanger, or poor draft. When tripped, it shuts down the burner to prevent fire and carbon-monoxide hazards. This is a manual-reset device, so a trip requires investigation, not just a reset.
The OEM Goodman rollout switch matches the factory 350°F trip point and bracket location exactly. Because this switch directly guards against combustion escaping the firebox, we strongly advise against generic substitutes with uncertain calibration.
A single-fastener, two-terminal replacement — about 10 minutes. Turn off power and gas first. Important: if a rollout switch has tripped, always diagnose the root cause (blockage, cracked heat exchanger, or venting fault) before returning the furnace to service. Replace the switch only after the underlying condition is corrected.
Fits Goodman GMPE125-5. Verify 350°F rating and part number before ordering.
