The Goodman B1370254 Stack Overtemp Switch is a genuine OEM flame-rollout / stack safety control for the GMNT080-4B gas furnace and compatible Goodman/Amana models. This manual-reset thermal switch mounts near the burner box and opens the ignition circuit if it senses excessive heat or flame rollout, shutting the furnace down to prevent damage and fire hazard.

Specifications

Part Number: B1370254 (OEM Goodman)
Type: Stack overtemp / flame rollout switch
Reset: Manual reset button
Fit: Goodman GMNT080-4B and compatible furnaces
Equipment: Gas furnace
Terminals: 1/4" quick-connect spade

OEM vs. Generic

The OEM B1370254 is calibrated to the exact trip temperature and mounting footprint your furnace requires. A generic rollout switch may trip at the wrong temperature or fit poorly, defeating its life-safety purpose. Because this component guards against fire, we strongly recommend the genuine OEM part.

Installation Difficulty

Easy (2/5). Typically 15–20 minutes. Cut power at the disconnect, note the wiring, unscrew the switch from the burner assembly, transfer the spade terminals, and remount. Important: a tripped rollout switch signals an underlying problem (blocked flue, cracked heat exchanger, or bad inducer) — diagnose and correct the root cause before returning the furnace to service. When in doubt, call a licensed HVAC technician.
