Goodman B1392139 View Port Bushing

The B1392139 is a genuine OEM view port bushing (sight-glass grommet) used on Goodman GDH80403AXBD gas furnaces and many other Goodman/Amana 80% AFUE models. It seats in the burner compartment access panel to create a sealed, heat-resistant window so a technician can visually confirm burner flame ignition and rollout without opening the cabinet. A cracked or missing bushing lets combustion air leak and can trip the flame-sensing sequence.

Specifications

Part number: B1392139
Type: View port / sight-glass bushing
Material: High-temperature molded polymer
Fits: Goodman GDH80403AXBD and compatible 80% AFUE furnaces
Function: Seals the flame-observation port

OEM vs. Generic

The genuine Goodman part is molded to the exact port diameter and rated for sustained heat-exchanger-adjacent temperatures. Generic grommets often use lower-temp rubber that hardens, shrinks, and falls out within a season, breaking the combustion-air seal. For a component this inexpensive, OEM is the clear choice.

Installation Difficulty

Easy (1/5). Press-fit replacement — power down the furnace, pop out the old bushing, and seat the new one by hand in under a minute. No tools required.
