The Goodman B1392139 View Port Bushing is a genuine OEM fitting for the WGFM28070V4BXAB gas furnace and compatible Goodman/Amana models. This bushing seats in the burner-compartment sight (view) port, providing a clean, heat-resistant grommet through which the flame can be safely observed while sealing the opening against air leakage. A missing or deteriorated bushing allows unwanted air infiltration that can affect combustion pressure and flame stability.

Specifications

Part number: B1392139
Type: View / sight port bushing (grommet)
Function: Seals and frames the burner-compartment view port
Material: High-temperature-rated bushing stock
Fitment: Goodman WGFM28070V4BXAB and select Goodman/Amana furnaces

OEM vs. Generic

This small OEM component is sized to snap precisely into the furnace's factory port opening. Generic grommets rarely match the bore and can fall out or fail to seal. At this price point, the genuine part is the obvious choice for a proper, lasting fit.

Install Difficulty

Easy (1/5). Press-fit — simply remove the old bushing and snap the new one into the port opening by hand. No tools required in most cases. Under 5 minutes with power off.
