Goodman B1392139 View Port Bushing

The B1392139 is a genuine OEM view port bushing for the Goodman/Amana AMH80903BNAA gas furnace. This small but important fitting seats in the burner compartment door and holds the sight-glass window that lets a technician observe the burner flame during operation. It also seals the opening, maintaining proper combustion-chamber pressure and keeping the burner box closed to code. A cracked, missing, or brittle bushing can allow air leakage, flame-signal problems, or a rattling access panel.

Specifications

Type: View port / sight-glass bushing (grommet)
Function: Retains burner viewport window and seals opening
Fits: Goodman/Amana AMH80903BNAA gas furnace
Material: High-temperature molded polymer
OEM Part Number: B1392139
Installation: Snap-fit into door opening

OEM vs. Generic

This genuine OEM Goodman bushing is molded to the exact diameter and profile of your furnace's viewport cutout, ensuring a snug, sealed fit. Generic grommets rarely match the specific bore and can fall out or fail to seal, defeating the purpose. At this price point, there is no reason not to use the factory part.

Install Difficulty: Very Easy

Rated Very Easy (1/5). With the furnace powered off, pop out the old bushing and press the replacement firmly into the door opening until it seats. A 2-minute, no-tools repair.

Tip: Inspect the sight glass while you're in there — replace it too if it's clouded or cracked so you can clearly monitor the flame.
