The Goodman B1392139 View Port Bushing is a genuine OEM sight-glass grommet for the AMH80905CNAB gas furnace. This small but important fitting seals the burner-observation port on the blower/burner access panel, letting a technician watch the flame during startup while keeping the combustion area properly closed. A cracked, brittle, or missing view-port bushing can allow air leakage around the inspection window and affect combustion sealing — an inexpensive part worth replacing whenever it shows wear.

Type: View-port / sight-glass bushing (grommet seal)
Function: Seals the burner-flame observation port
Material: High-temperature molded bushing
Installation: Press-fit into the panel port opening
OEM part number: B1392139
Fits: Goodman/Amana AMH80905CNAB and compatible furnaces

OEM vs. Generic

The OEM Goodman B1392139 is molded to the exact port diameter of the AMH80905CNAB access panel, so it snaps in flush and holds its seal at furnace operating temperatures. Generic grommets are rarely sized to the factory port and may fall out or fail to seal, so we stock the genuine part.

Installation Difficulty

Very Easy (1/5). No tools required beyond removing the access panel. Push the old bushing out, clean the port opening, and press the new one into place until it seats. A 5-minute job that any homeowner or technician can handle.
