Goodman B1392139 View Port Bushing

The B1392139 is a genuine OEM view port bushing (sight-glass grommet) engineered for the Goodman/Amana AMH80903BNAB 80% gas furnace and closely related AMH80 series models. This small but essential rubber/silicone bushing seals the burner observation port, letting a technician safely watch the flame and hot surface ignitor during operation while keeping combustion air isolated from the furnace cabinet.

Specifications

OEM Part Number: B1392139
Part Type: View port / sight-glass bushing
Compatible Model: AMH80903BNAB (and select AMH80 furnaces)
Material: High-temperature grommet
Brand: Goodman / Amana (interchangeable OEM part)

OEM vs. Generic

This is the genuine OEM bushing, molded to the exact port diameter so it seats flush without air leaks. Universal grommets often sit loose, allowing combustion-air bypass and nuisance flame-signal issues. For a proper seal, the OEM part is the safe choice.

Install Difficulty

Easy (1/5) — Press-fit replacement. Power down the furnace, pop out the old bushing, and press the new one into the port. No tools required. Under 5 minutes.
