The Goodman B1392139 View Port Bushing is a genuine OEM part for the ACSS920804CNAA gas furnace and compatible Goodman/Amana models. This bushing frames the flame-inspection sight port on the burner compartment, providing a clean, sealed opening so technicians can safely observe burner flame quality during service. A cracked or missing bushing can allow heat and combustion gases to escape around the viewing port.

Specifications

OEM Part Number: B1392139
Brand: Goodman (genuine OEM)
Component Type: View/sight port bushing (grommet)
Function: Seals and frames the flame-observation port
Equipment: Furnace
Primary Fit: ACSS920804CNAA (verify against your parts list)

OEM vs. Generic

The genuine Goodman bushing is heat-rated and dimensioned to seat tightly in the cabinet opening. Generic grommets may not match the bore, can melt or harden near the burner heat, and may compromise the cabinet seal. The OEM part maintains correct fit and combustion-area integrity.

Installation Difficulty

Easy (1/5). Press the old bushing out and snap the new one into the panel opening — typically no tools required. Always shut off power and gas before opening the burner compartment. Defer to a licensed HVAC professional if you are not comfortable working near the burners.
