The Goodman B1392139 view port bushing is the OEM grommet/fitting that seals the flame-inspection sight port on the burner compartment door. It is a direct-fit replacement for AMH80904BXCC gas furnaces and other compatible Goodman/Amana models. This bushing keeps the combustion chamber sealed while still allowing you to visually check the burner flame during service. A cracked or missing bushing can affect combustion air sealing and allow the sight glass to fall out.

Type: View port bushing / sight-glass grommet
Function: Seals the burner inspection port
Material: Heat-resistant molded fitting
Fits: AMH80904BXCC and compatible Goodman/Amana furnaces
OEM part number: B1392139

OEM vs. Generic

Because this bushing sits on the sealed combustion chamber, the OEM Goodman fitting is molded to the exact port diameter and temperature rating your furnace requires. Generic grommets may not seal correctly, which can compromise combustion-air integrity. OEM is strongly recommended for any part on the burner assembly.

Installation Difficulty

Easy (DIY-friendly). With the furnace powered off and the burner door removed, pop the old bushing out and press the new one into the port. No tools or adhesives are typically required. Under 5 minutes for most technicians and handy homeowners.
