The B1392139 is a genuine OEM view-port bushing for the Goodman/Amana AMH80403ANBC gas furnace. This small but essential grommet seals the sight-glass opening in the burner compartment, allowing safe visual inspection of the flame while maintaining the integrity of the combustion enclosure.
The OEM bushing is molded to the precise diameter and heat rating of the AMH80403ANBC view port, so it snaps in cleanly and holds a tight seal. Generic substitutes are often the wrong bore or a lower temperature grade, which can distort near the burner box and let air infiltrate. Given the low price, OEM is the sensible choice.
Very Easy (1/5). Press-fit replacement — pop out the old bushing and press the new one into the port. Under 10 minutes. Turn off power and gas before opening the burner compartment.
A common wear item on aging furnaces; inexpensive insurance for a proper combustion-chamber seal.
