The Goodman B1392139 View Port Bushing is a genuine OEM grommet/bushing that seals the burner-compartment sight (view) port on the ADSH800603AXAB furnace. It lets a technician safely observe the flame while keeping the combustion enclosure sealed, preserving proper draft and preventing air leakage around the viewing window.
The genuine OEM B1392139 is molded to the exact port diameter, so it snaps in and holds a tight seal against the burner box. Aftermarket grommets rarely match the bore precisely and can fall out or leak combustion air, upsetting the pressure switch and draft. At this price point, there is no reason not to fit the correct OEM part.
Very Easy (1/5). A push-in replacement — power down the furnace, pop out the old bushing, and press the new one into the port opening. Takes under 5 minutes and requires no tools. Confirm it seats fully flush all the way around.
