The Goodman B1392139 View Port Bushing is a genuine OEM sight-glass grommet for the burner observation window on the Amana/Goodman AMH81005CNAA gas furnace. This small but essential fitting seals the view port, allowing technicians to safely inspect the burner flame while maintaining the integrity of the combustion enclosure.

Specifications

Part type: View port bushing / sight-glass grommet
Material: High-temperature molded polymer
Function: Seals and frames the burner observation window
Fits: Amana/Goodman AMH81005CNAA gas furnace
Brand: Genuine Goodman OEM

OEM vs. Generic

Because this bushing sits close to the combustion area, the OEM part uses a temperature-rated material sized to the exact port dimensions. Generic or improvised grommets can shrink, melt, or fit loosely, compromising the seal. The genuine B1392139 ensures a proper, lasting fit.

Installation Difficulty

Very Easy (1/5). This is a press-fit component — simply remove the old bushing and seat the replacement into the view port opening by hand. No tools required, under 5 minutes. Ensure the furnace is off and cool before servicing.
