The Goodman B1392139 is a genuine OEM view port bushing designed for the AMH80603ANAA and compatible Goodman/Amana gas furnaces. This small but essential fitting frames the burner observation (sight) port, providing a clean, heat-tolerant grommet that lets technicians visually inspect the burner flame while protecting the panel opening. Over time these bushings can crack, discolor, or fall out, leaving an unsealed gap in the combustion viewing area.
The genuine OEM bushing is molded to the precise diameter and profile of your furnace's view-port opening, snapping in securely for a flush finish. Generic substitutes rarely match the exact bore and can loosen or degrade under heat. For a proper, lasting fit, OEM is the reliable choice.
Very Easy (1/5) — A tool-free press-fit replacement. Power down the furnace, pop out the old bushing, and press the new one into the panel opening until it seats. Takes less than a minute.
A genuine Goodman detail part that keeps your furnace panel complete and inspection-ready.
