The Goodman B1392139 is a genuine OEM view port bushing designed for the AMS80704BNAA gas furnace and related Goodman/Amana models. This small but important component seals and frames the burner observation (sight) port on the furnace cabinet, allowing technicians to view flame color and ignition while keeping the combustion area properly enclosed. A cracked, missing, or brittle bushing can allow air leakage around the port and make flame inspection difficult.

Part number: B1392139
Type: View port bushing / sight-glass grommet
Material: High-temperature molded polymer
Function: Seals and frames the burner observation port
Fits: AMS80704BNAA and related Goodman/Amana furnaces

OEM vs. Generic: Because it is molded to the exact port diameter and cabinet thickness of the AMS80704BNAA, the OEM B1392139 snaps in cleanly and holds its seal under repeated heat cycling. Generic grommets rarely match the port geometry and can fall out or degrade quickly. At this price point, buying the correct OEM part is a simple, low-cost way to keep the furnace factory-correct.

Install difficulty: Very easy (1/5). Simply press the old bushing out and snap the new one into the cabinet view port — no tools required. A one-minute replacement anyone can do with the power off.

Genuine Goodman OEM quality, shipped fast by National HVAC Parts.
