Goodman B1392139 View Port Bushing

The Goodman B1392139 is a genuine OEM view port bushing designed for the ADVC81005CNAA furnace and compatible Goodman/Amana gas furnace models. This small but essential grommet seats the sight-glass window on the burner compartment, letting a technician safely observe the flame during operation while maintaining the sealed integrity of the heat exchanger area.

Specifications

Part Type: View port / sight glass bushing
OEM Part Number: B1392139
Brand: Goodman / Amana
Application: Gas furnace burner inspection port
Fits: ADVC81005CNAA and related Goodman furnaces

OEM vs. Generic

This is the factory-original Goodman component, machined to the exact bore diameter of the burner box opening. Generic universal bushings often fit loosely and can allow flue gas seepage or fall out during service. For a leak-free, drop-in fit we recommend the OEM part.

Installation Difficulty

Easy (1/5). Press-fit replacement — no tools required. Power down the furnace, pop out the old bushing, and seat the new one into the port opening.
