The Goodman B1392139 View Port Bushing is a genuine OEM part for the AMSS921005CNAA gas furnace and compatible Goodman/Amana models. This bushing seals and frames the burner sight-glass / inspection port, letting technicians safely observe flame and ignition while maintaining the airtight integrity of the combustion chamber.

Specifications

OEM Part Number: B1392139
Type: View port / sight-glass bushing
Fits: AMSS921005CNAA and compatible Goodman/Amana furnaces
Material: High-temperature rated polymer
Function: Inspection-port seal and grommet

OEM vs. Generic

Because it borders the combustion area, this OEM bushing is molded from heat-rated material sized to your furnace's port. Generic grommets may not tolerate sustained heat, can shrink or crack, and compromise the chamber seal. The genuine part preserves both safety and proper combustion pressure.

Install Difficulty

Very Easy (1 of 5). Power down the furnace, remove the old bushing from the port, and press the replacement into place until flush. No special tools needed.
