The Goodman B1392139 View Port Bushing is a genuine OEM replacement grommet that seats the sight-glass/inspection port on Amana AMES960803BNAA 96% AFUE modulating gas furnaces. This bushing keeps the flame-observation window sealed and correctly aligned, protecting the combustion chamber's air seal and letting you safely view burner ignition during service.
This is a factory-original Goodman component built to the exact tolerances of the AMES960 series combustion door. Generic bushings often sit loose or shrink under repeated heat cycling, breaking the air seal and skewing furnace pressure readings. The OEM part guarantees a proper seal and correct fit the first time.
Easy (1/5). Snaps into the view-port opening in seconds with no tools. Cut power at the furnace switch before opening the burner compartment. If you are unsure, a qualified HVAC technician can install this in minutes during routine service.
Compatibility note: Always confirm your furnace model and part number before ordering. This listing covers the OEM B1392139 as used on AMES960803BNAA furnaces.
