The Goodman B1392139 View Port Bushing is a genuine OEM component designed for the AMSS920803BNAA gas furnace and compatible Goodman/Amana models. This small but essential rubber/plastic bushing seals the observation port on the burner compartment, allowing technicians to safely view flame ignition while keeping the combustion area sealed against air leaks and drafts. A cracked, missing, or degraded view port bushing can cause nuisance sight-glass fogging, minor air infiltration, and failed combustion inspections.

Specifications

Part Number: B1392139
Type: View port bushing / sight-glass grommet
Brand: Goodman (fits Amana-branded equipment)
Compatible Model: AMSS920803BNAA and select Goodman/Amana 92% furnaces
Application: Gas furnace burner observation port

OEM vs. Generic

This is a factory OEM Goodman part, guaranteed to match the original diameter, temperature rating, and press-fit tolerance of your furnace's port. Aftermarket bushings often use lower-grade material that hardens and cracks near the burner heat, leading to repeat failures. For a component this inexpensive, the OEM part is the clear value choice.

Installation Difficulty

Easy (DIY-friendly). No tools or wiring required — power down the furnace, press the old bushing out, and seat the new one in the port opening. Typical replacement time is under 5 minutes. Always shut off gas and power before servicing.
