The Goodman B1392139 is a genuine OEM view port bushing for the Goodman/Amana ADSS800603AXAB furnace and related models. This small but important fitting seats in the burner/combustion compartment access opening, providing a heat-resistant, sealed pass-through so technicians can safely observe the flame and ignition sequence through the sight port. A cracked, missing, or brittle bushing can allow air leakage around the view port and affect combustion-chamber pressure and observation clarity.
The Genuine OEM bushing is molded to the exact port diameter and made from heat-rated material suited to the combustion area. Generic grommets often fail to fit the opening precisely or degrade under sustained heat. For a secure, long-lasting seal at the view port, choose OEM.
Very Easy (1/5). With the furnace powered down, press or snap the old bushing out of the view-port opening and seat the new one until it locks in place. Typically under 5 minutes with no special tools required.
