The Goodman B1392139 View Port Bushing is a genuine OEM grommet/bushing that seats in the burner sight (view) port of Goodman and Amana AMVC80603BNBD 80% two-stage furnaces. It seals the inspection opening on the burner box so technicians can safely observe the flame while keeping the combustion area properly enclosed and free of air leaks.
The genuine Goodman bushing is molded from a heat-rated compound sized to the exact port diameter, so it seats snugly and withstands burner-box temperatures without hardening or shrinking. Generic grommets may not fit the opening or can degrade near the heat, allowing air leaks that affect combustion. For a few dollars, the OEM part is the right call.
Easy — DIY-friendly. With power off, simply pop out the old bushing and press the new one into the view port. No tools or special skills required; a 5-minute job. Confirm it seats fully and evenly around the opening.
Keep your AMVC80603BNBD burner box properly sealed with the genuine Goodman B1392139 view port bushing.
