The Goodman B1392139 View Port Bushing is a genuine OEM replacement for the Goodman/Amana ACVC960804CNAA modulating gas furnace. This bushing seals the combustion sight/view port, allowing technicians to inspect the burner flame while maintaining the airtight integrity of the sealed-combustion chamber. A missing or degraded bushing can cause air infiltration that affects flame quality and pressure-switch operation.
The genuine Goodman OEM bushing is molded from heat-resistant material sized to the furnace's view-port opening for an airtight fit. Generic grommets may not withstand combustion-area temperatures or seal completely. OEM ensures proper sealing and longevity.
Very easy — under 5 minutes. With the furnace powered off and cool, press the bushing into the view-port opening until fully seated. No tools required.
