Goodman B1392139 View Port Bushing

The Goodman B1392139 is the OEM view port bushing (sight-glass grommet) that seals the flame-inspection opening on the burner compartment door of Goodman VMS81005CXAA furnaces. This small rubber-and-plastic fitting keeps the observation window secure while maintaining the sealed combustion enclosure the furnace was designed around. A cracked, missing, or hardened bushing lets the sight glass rattle loose and can compromise the combustion-air seal, so replacing it with the correct part restores safe, quiet operation.

Specifications

Part number: B1392139
Type: View port / sight-glass bushing
Category: Furnace fitting
Fits: Goodman VMS81005CXAA and compatible 80% furnace platforms
Material: Heat-resistant molded bushing
Brand: Goodman (OEM)

OEM vs. Generic

The genuine Goodman OEM bushing is molded to the exact port diameter and seats flush, holding the sight glass without gaps. Generic aftermarket grommets are cheaper but often run slightly out-of-spec, leading to a loose window or an imperfect seal. For a part this inexpensive, the OEM fit is well worth it.

Installation Difficulty

Easy (1/5). No tools beyond a screwdriver to open the panel. Power down the furnace, pop the old bushing out, press the new one into the port, and reseat the sight glass. Under five minutes for most DIY owners.
