The Goodman B1392139 View Port Bushing is a genuine OEM fitting for the AMES920804CNAA gas furnace and related Goodman/Amana models. This bushing surrounds the burner sight/view port, providing a clean, sealed grommet through which a technician can observe the burner flame. A cracked or missing bushing can allow air leaks around the observation port and compromise the sealed combustion cabinet on high-efficiency furnaces.

Specifications

Compatible Model: AMES920804CNAA
Category: Fitting / Hardware
Function: View / sight port grommet and seal
Material: Heat-resistant molded bushing

OEM vs. Generic

The genuine OEM B1392139 is sized to the exact port opening and panel thickness of Goodman/Amana furnace cabinets, providing a tight, retained seal. Generic grommets rarely match the port diameter and can loosen or fall out, leaving an unsealed opening in the combustion cabinet. For correct sealing and fit, use the OEM bushing.

Installation Difficulty

Very Easy — DIY. The bushing presses into the view-port opening by hand with no tools required. It is an inexpensive item worth keeping on hand during routine furnace service.

Genuine Goodman OEM quality at a budget-friendly price. Ships fast from stock.
