The Goodman B1392139 View Port Bushing is a genuine OEM sight-port grommet used to seal the burner observation window on Amana/Goodman AMH81005CNBC gas furnaces. This small but essential fitting maintains the integrity of the combustion enclosure while allowing technicians to inspect flame quality.

Over time the original bushing can dry out, crack, or fall out during service. A missing or damaged view port bushing can allow air leakage that affects flame appearance and combustion readings.

OEM vs. Generic

This is a genuine OEM Goodman bushing sized to the exact port diameter of your furnace panel. Universal or generic grommets rarely seat correctly and can pop loose or fail to seal, undermining a clean visual inspection. OEM guarantees a snug, factory fit.

Install Difficulty

Very Easy (1/5). Push-fit installation into the observation port — no tools required. Disconnect power before opening the burner compartment.
