The Goodman B1392139 View Port Bushing is a genuine OEM component for the ACVM960805DXBA furnace and other compatible Goodman models. This bushing fits the burner observation (sight) port on the furnace, providing a clean, sealed grommet that frames the viewing window so technicians can safely inspect the burner flame while keeping the combustion area properly enclosed.
The OEM B1392139 is sized to the exact view-port opening on Goodman furnaces, ensuring a flush, secure fit that maintains the combustion enclosure. Generic substitutes may not match the port diameter, can fit loosely, or may not withstand the heat near the burner area. The genuine bushing delivers a precise, safe, and lasting fit.
Replacement takes seconds. Power down the furnace, remove the old bushing from the view port, and press the new B1392139 into place until fully seated. No tools required. This inexpensive part restores a clean, sealed sight port for safe flame inspection during maintenance.
Keep your Goodman furnace burner port sealed and inspection-ready with the genuine B1392139 view port bushing.
