Goodman B1392139 View Port Bushing

The Goodman B1392139 is a genuine OEM view port bushing (sight-glass grommet) engineered for the AMH80904BNAC gas furnace and compatible Goodman/Amana 80% AFUE models. This bushing seats the flame-observation sight glass in the burner compartment access panel, sealing the port against air leakage while allowing safe visual inspection of the burner flame during service.

Although inexpensive, a cracked or missing view port bushing is a common cause of nuisance air infiltration and rattling panels. Replacing it with the correct OEM part restores a proper seal and keeps the combustion area viewable.

Specifications

OEM Part Number: B1392139
Type: View port / sight-glass bushing
Fits: AMH80904BNAC and compatible Goodman & Amana 80% furnaces
Material: Heat-resistant grommet composite
Function: Seals and mounts burner flame sight glass

OEM vs. Generic

The genuine Goodman OEM bushing is molded to the exact port diameter and temperature rating of the AMH80904BNAC cabinet. Generic grommets often fit loosely, degrade faster near combustion heat, and can fall out. For a small-cost part in a combustion area, OEM is strongly recommended.

Installation Difficulty

Easy (1/5). Press-fit replacement — no tools required beyond removing the burner access panel. Typical install time under 5 minutes. Always shut off gas and power to the furnace before servicing.
