The Goodman B1392139 is a genuine OEM view port bushing for the AMH80603ANBD gas furnace and compatible Goodman/Amana models. This bushing frames and seals the sight-glass viewing port on the burner compartment, allowing a technician to safely observe the flame while maintaining the integrity of the combustion enclosure. A missing or cracked bushing can allow air leakage and affect combustion-area sealing.
This genuine OEM bushing is molded to the exact diameter and heat rating of the AMH80603ANBD viewing port, ensuring a snug, heat-resistant fit. Generic grommets may not tolerate combustion-area temperatures or may fit loosely, compromising the seal. OEM ensures correct fit and durability in a high-heat environment.
Very Easy (1 of 5). Replacement takes just a few minutes: power off the furnace, remove the burner-compartment door, press out the old bushing, and snap the new one into place. No tools are typically required.
