The OEM Goodman B1392139 View Port Bushing is the sealing grommet for the burner inspection (sight) window on the AMH80904BXAA gas furnace and compatible Goodman/Amana models. This small but important fitting maintains a proper seal around the view port so the combustion chamber stays sealed while still allowing you to observe flame quality during service. A cracked, brittle, or missing bushing can allow air infiltration that disrupts the flame-sensing and pressure balance of the burner assembly.

Type: View port / sight-glass sealing bushing
Material: Heat-resistant molded grommet
Function: Seals the burner inspection window
Fits: Goodman/Amana AMH80904BXAA and related 80% furnaces
OEM Part Number: B1392139

OEM vs. Generic

Because this bushing must fit a precise cutout and withstand sustained heat near the burner box, an exact-fit OEM part is the right call. The genuine Goodman bushing is molded to the correct diameter and thickness for a snug, air-tight seal. Ill-fitting generic grommets tend to fall out or degrade quickly under heat.

Installation Difficulty: Easy

Rated Easy — one of the simplest furnace repairs. With the furnace powered down, pop out the old bushing and press the new one into the view-port opening by hand. No tools required in most cases. A quick, inexpensive part to keep on hand during any burner-area service.
