Goodman B1392139 View Port Bushing

The Goodman B1392139 is the genuine OEM view-port bushing (sight-glass grommet) that seals the flame-inspection window on the burner compartment of AMH81155CXCB and related Amana/Goodman furnaces. This small bushing maintains a proper air seal at the observation port so combustion air is not drawn in through the viewing hole, which can otherwise disturb the flame pattern and burner pressure.

Specifications

Function: View-port / sight-glass sealing bushing
OEM Part Number: B1392139
Fits: AMH81155CXCB and related Goodman/Amana gas furnaces
Location: Burner compartment inspection port

OEM vs. Generic

Because this bushing sits directly on a combustion enclosure, OEM material is heat-rated for the application. Generic grommets can shrink or melt, breaking the air seal. At this price point there is no reason not to use the factory part.

Installation Difficulty

Easy (1/5). Press-fit into the view-port opening by hand. No tools required. Service with the furnace powered off.
