Goodman B1392139 View Port Bushing

The B1392139 is a genuine OEM Goodman view port bushing (sight-glass grommet) engineered for the AMH81405DXCB gas furnace and compatible Goodman and Amana models. This small but critical fitting seals the flame-inspection sight port on the burner compartment, allowing a technician to visually confirm ignition and flame quality while keeping the heat-exchanger vestibule properly sealed against air leakage.

Part type: View port / sight glass bushing (grommet)
OEM part number: B1392139
Fits: AMH81405DXCB and related Goodman/Amana 80% furnaces
Material: High-temp molded polymer
Function: Seals the flame observation port

OEM vs. Generic

Choosing the genuine Goodman OEM B1392139 guarantees an exact dimensional and heat-tolerance match to your furnace's burner box. Generic aftermarket bushings often use lower-grade material that can deform or crack near the heat exchanger, breaking the seal. For a sealed-combustion component this close to the flame, OEM is the safe choice.

Installation Difficulty

Easy (1/5). Push-fit replacement in minutes with the furnace powered down. No tools required beyond removing the burner-door panel. Always shut off gas and power before servicing.
