The Goodman B1392139 is a genuine OEM view port bushing built for the AMES920803BNAA gas furnace. It fits the flame-inspection sight port on the combustion chamber cover, providing a clean, sealed opening through which the burner flame can be observed during service.

Over time heat and handling can crack or deform the original bushing, allowing air infiltration around the sight glass and disrupting the sealed combustion area. The factory-spec B1392139 restores a proper, heat-tolerant seal at the inspection port.

Specifications

Manufacturer: Goodman (Amana family)
OEM Part Number: B1392139
Type: View / sight port bushing (grommet)
Fits Model: AMES920803BNAA furnace
Equipment: Gas furnace combustion cover

OEM vs. Generic

The OEM bushing is sized to the exact port diameter and rated for the heat near the combustion area. Generic grommets may not tolerate the temperature or match the bore, leading to a poor seal. For reliable, code-safe combustion sealing, use the genuine B1392139.

Install Difficulty

Easy (1/5). Push-fit into the sight port; no tools required. Turn off power and gas and allow the furnace to cool before servicing.
