The Goodman B1392139 View Port Bushing is a genuine OEM component for the AMS81155CNAA gas furnace and compatible Goodman/Amana models. This small bushing seats into the burner compartment cover to form the observation (sight-glass) port, letting a technician safely watch flame ignition and burner operation without opening the sealed combustion area. Though inexpensive, a cracked, missing, or brittle view port bushing can allow air leaks that disturb the combustion-air balance and affect flame quality.

Specifications

Type: View port bushing / sight-glass grommet
Function: Sealed burner-flame observation port
Material: High-temperature molded bushing
Fits: AMS81155CNAA and compatible Goodman & Amana furnaces
Part number: B1392139

OEM vs. Generic

Because this bushing must handle sustained heat and seal precisely into the factory opening, the genuine Goodman OEM part is the only reliable fit. Generic grommets rarely match the diameter or heat rating and can deform, distort the flame-observation view, or leak combustion air. At this price, there is no reason not to use OEM.

Installation Difficulty

Very Easy (DIY-friendly). With power and gas off, press the old bushing out of the burner cover and snap the new one into place. No tools required. Estimated time: under 5 minutes.
