Goodman B1392139 View Port Bushing

The Goodman B1392139 is a genuine OEM view port bushing designed for the AMSS921005CNAB gas furnace. It seats in the combustion-chamber sight port, maintaining a proper seal around the viewing window so technicians can safely inspect the burner flame without compromising the sealed-combustion enclosure. A missing or damaged bushing can allow air leakage that disturbs the pressure switch and reduces combustion efficiency.

Type: View/sight-port bushing
Compatible Model: AMSS921005CNAB (and select Goodman/Amana furnaces)
Material: Heat-resistant molded polymer
Application: Combustion-chamber flame-inspection port

OEM vs. Generic

The OEM bushing is dimensioned to the exact port bore on this furnace and rated for the elevated temperatures near the burner assembly. Generic substitutes may not seal correctly or withstand the heat. For a safe, air-tight repair, use the OEM bushing.

Install Difficulty

Very Easy (1/5) — A tool-free press-fit part. Power down the furnace, remove the old bushing, and press the new one into the view port until seated.
