The Goodman B1392139 View Port Bushing is a genuine OEM grommet that seals the flame-inspection sight port on the burner compartment of the AMEH801005CNAA and compatible Goodman/Amana gas furnaces. This small but important part lets a technician safely observe the burner flame while maintaining the pressure seal of the combustion enclosure. A cracked, brittle, or missing bushing can allow air leakage that upsets combustion and pressure-switch operation.
The genuine OEM B1392139 is molded from heat-resistant material rated for the burner-box environment and sized to the exact port diameter. Generic grommets may not tolerate the sustained heat, hardening and falling out. For a component adjacent to the combustion chamber, OEM is the safe pick.
This is a simple snap-in replacement. With the furnace powered off and cool, remove the burner-compartment door, pop out the old bushing, and press the new one into the port. No tools or gas work required. Estimated time: 5–10 minutes.
