The Goodman B1370254 Stack Overtemp Switch is a genuine OEM manual-reset safety control for the GMNT100-4B gas furnace and compatible Goodman/Amana models. Mounted near the burner box or flue collector, this switch monitors for abnormal heat and flame rollout — a dangerous condition where flames escape the heat exchanger due to a blocked flue, cracked exchanger, or poor combustion. When tripped, it immediately cuts power to the gas valve to prevent fire and carbon-monoxide hazards.

Specifications

Function: Stack overtemp / flame rollout safety switch
Reset: Manual (push-button)
Configuration: Normally closed, opens on overtemperature
OEM Part Number: B1370254
Compatibility: GMNT100-4B and select Goodman/Amana furnaces
Type: Direct-replacement factory component

OEM vs. Generic

The genuine OEM B1370254 is factory-calibrated to trip at the precise temperature your furnace requires. Because this is a life-safety device that guards against flame rollout, we strongly recommend the exact OEM part over generic substitutes that may have a different trip point or slower response.

Symptoms of a Tripped or Failed Rollout Switch

Furnace locks out and will not fire
Push-button has popped and requires reset
Repeated trips (indicates an underlying combustion or venting problem)

Installation Difficulty: Easy (DIY-Friendly)

Disconnect furnace power, remove the mounting screws, transfer the two wire terminals, and mount the new switch in the identical position. Allow 15–20 minutes. Important: if the switch trips again after replacement, do not bypass it — have a licensed technician inspect the heat exchanger, burners, and flue for the root cause.
