The Goodman B1392139 View Port Bushing is a genuine OEM replacement for the sight-glass/inspection port on the Amana AMES920805CNAA gas furnace. This small but important grommet seals the viewing port used to observe the burner flame and igniter, keeping the combustion area properly enclosed and preventing air leakage that can affect flame stability and safety sensing.

Specifications

Part Number: B1392139
Type: View port bushing / inspection port grommet
Fits Model: AMES920805CNAA (and select Goodman/Amana furnaces)
Function: Seals burner observation port
Equipment: Gas furnace

OEM vs. Generic

As a genuine OEM Goodman component, this bushing matches the port diameter and material spec exactly, so it seats fully and holds its seal at furnace operating temperatures. Off-brand grommets may be the wrong durometer or size, allowing leaks or falling out over time. For a reliable seal on a safety-related port, OEM is the right choice.

Install Difficulty

Very Easy (1 of 5). A 5-minute, no-tools press-fit replacement. Shut off the furnace, remove the old bushing from the view port, and press the new one into place. No wiring or gas connections involved.
