Goodman B1392139 View Port Bushing

The B1392139 is a genuine OEM Goodman view-port bushing (grommet) used at the burner sight/observation port of the DMS80704BNA gas furnace and compatible Goodman/Amana models. This small but important fitting seals and protects the opening used to observe the burner flame during ignition and operation, helping maintain the proper combustion-air seal on the burner compartment. A missing, brittle, or cracked bushing can allow air leakage that affects flame quality and combustion sensing.

Specifications

Type: View/sight port bushing (grommet fitting)
Location: Burner observation port on furnace cabinet
Function: Seals and frames the flame-viewing opening
Material: Heat-resistant molded bushing
Fits: Goodman DMS80704BNA and compatible furnaces
Part number: B1392139

OEM vs. Generic

The genuine OEM bushing is molded to the exact port diameter for a snug, secure seal that stays put through heating cycles. Generic grommets may be loose or use materials less tolerant of heat, leading to fallout or deformation. For a proper combustion seal, OEM is the safe choice.

Installation Difficulty

Very Easy (1/5). A snap-in replacement taking just a few minutes — press the old bushing out and the new one into the port opening. No tools required in most cases. Shut off power before opening the burner compartment.
