The Goodman B1392139 View Port Bushing is a genuine OEM sight-port grommet used on the AMH81005CNBA 80% AFUE gas furnace and many related Goodman/Amana models. This small but essential component seals and frames the flame-inspection viewing port on the burner compartment, letting technicians and homeowners safely observe burner ignition and flame quality without opening the sealed combustion area.

Over time the original bushing can crack, harden, or fall out from repeated heat cycling, allowing air leakage around the sight port and making flame inspection difficult. Replacing it with the correct OEM part restores a clean, secure seal and proper combustion-compartment integrity.

Part number: B1392139
Type: View port / sight-glass bushing (grommet)
Fits: Goodman & Amana AMH81005CNBA and compatible furnace platforms
Material: High-temperature molded polymer
Function: Seals and frames the burner flame-inspection port

OEM vs. Generic: The genuine Goodman B1392139 is molded to exact factory dimensions for a snug, leak-free press-fit and is rated for continuous furnace heat exposure. Generic substitutes are often the wrong diameter or use lower-grade plastic that deforms near the burner, leading to a loose fit or premature failure. For a sealed combustion compartment, the OEM part is the reliable choice.

Install difficulty: Easy (1/5). Turn off power and gas, remove the old bushing by hand, and press the new one into the port opening. No tools or special skills required — typically a 2-minute job. Always confirm your model number before ordering.
