The Goodman B1392139 View Port Bushing is a genuine OEM component for the AMS81005CXAD furnace and other compatible Goodman and Amana gas furnaces. This bushing seats in the burner-compartment access panel and holds the sight-glass/view port in place, allowing technicians to visually inspect burner flame and ignition through a sealed opening. It maintains the integrity of the combustion-air seal while preventing heat and flue-gas escape around the port.

Specifications

Part number: B1392139
Type: View port bushing / sight-glass grommet
Material: High-temperature molded polymer
Function: Retains and seals the burner-inspection view port
Fits: Goodman / Amana AMS81005CXAD and compatible 80% furnaces

OEM vs. Generic

Because this bushing must withstand sustained burner-compartment heat and maintain a tight seal, the genuine OEM Goodman part is strongly preferred. Generic substitutes may use lower-temperature plastics that warp or crack, breaking the combustion seal. The OEM part guarantees exact fit into the factory opening.

Installation Difficulty

Very Easy (1/5). No tools or wiring required in most cases — simply press the old bushing out and snap the replacement into the panel opening, then reseat the view port. A quick maintenance item that restores a proper combustion-compartment seal.
