The Goodman B1392139 View Port Bushing is a genuine OEM part for the AMVC961005DNBA condensing gas furnace. It fits the burner observation (sight) port, providing a sealed grommet through which the flame can be safely observed during service while maintaining the airtight integrity of the combustion chamber. A cracked or missing bushing can allow combustion-air leaks that disrupt the sealed burner box.
This factory-original bushing is rated for the high temperatures near the burner assembly and sized to seal the exact port opening. Generic substitutes may not withstand the heat or seal properly, compromising the sealed-combustion design. OEM is strongly recommended for safety and fit.
Very Easy (1/5). Under 5 minutes. Power down the furnace, remove the burner-compartment door, press the old bushing out, and seat the new one into the port opening.
