Goodman B1392139 View Port Bushing

The B1392139 is a genuine Goodman view port bushing (sight-glass grommet) for the AMVC801005CNAA two-stage variable-speed 80% AFUE gas furnace. It snaps into the burner-compartment inspection port, holding the sight glass in place and maintaining the seal a technician relies on when checking flame quality and ignition. A missing or brittle bushing lets the sight window rattle loose and can compromise the combustion-area seal.

Specifications

OEM Part Number: B1392139
Compatible Model: AMVC801005CNAA
Equipment Type: Gas Furnace (80% AFUE)
Function: Retains and seals combustion view/sight port
Material: High-temperature molded polymer

OEM vs. Generic

Because this bushing sits next to the burner box, temperature rating matters. The OEM B1392139 is molded from a heat-rated compound sized to the factory port diameter. Generic rubber grommets can shrink, harden, or deform near combustion heat — the OEM part is the safe, correct choice.

Installation Difficulty

Easy (1 of 5). Tool-free press-fit — pop out the old bushing and press the new one into the port. Under 5 minutes. Turn off power and gas before opening the burner compartment.
