Goodman B1392139 View Port Bushing

The B1392139 is a genuine Goodman view-port bushing — the grommet/collar that seals the sight-glass observation port on the furnace burner or blower compartment. It lets technicians view the flame or inducer while keeping the cabinet air-tight around the opening. A cracked or missing bushing can cause air leaks and improper draft readings. This OEM bushing is an exact-fit replacement for the Goodman/Amana AMV80704BXA furnace and models sharing the same port.

Specifications

OEM Part Number: B1392139
Type: View-port / sight-glass bushing (grommet)
Material: Heat-resistant molded polymer
Function: Seals the observation port opening in the cabinet
Fits: Goodman & Amana furnaces incl. AMV80704BXA
Equipment: Gas Furnace

OEM vs. Generic

This small but important fitting is molded to the exact port diameter and heat rating of the original. Universal grommets often don't seat fully or degrade near burner heat, allowing air infiltration that skews combustion. The OEM bushing restores a proper, sealed factory fit.

Installation Difficulty

Very Easy (1/5). Press the old bushing out of the port and snap the new one into place — no tools required. A 2-minute replacement, ideally done alongside any burner or inducer service.
