The Goodman B1392139 View Port Bushing is a genuine OEM sight-glass grommet used on the AMH80403AXBB gas furnace and compatible Goodman/Amana models. It seats in the burner-compartment viewing port, protecting the sheet-metal edge and holding the sight glass or flame-observation port securely in place. A cracked, brittle, or missing bushing can allow air leakage around the port and make it difficult to inspect the burner flame during service.

Specifications

OEM Part Number: B1392139
Part Type: View Port / Sight-Glass Bushing
Material: High-temperature molded grommet
Fits: Goodman/Amana AMH80403AXBB furnaces
Application: Burner compartment view port
Brand: Genuine Goodman OEM

OEM vs. Generic

The genuine OEM B1392139 is molded to the exact port diameter and temperature rating of your furnace, so it seats flush and holds up to the heat inside the burner box. Generic grommets are often the wrong bore size or a lower temperature grade, leading to loose fit, rattles, or premature cracking. For a wear part this inexpensive, OEM is the smart choice.

Installation Difficulty: Easy

This is a snap-in press-fit part. Power down the furnace, remove the old bushing, and press the new one into the port opening — no tools or wiring required. Most homeowners and technicians complete the swap in under two minutes.

Always disconnect power and gas before servicing your furnace. If you are unsure of the repair, consult a licensed HVAC technician.
