Goodman B1392139 View Port Bushing

The B1392139 view port bushing is a genuine OEM sight-glass grommet designed for the Goodman/Amana AMS80403AXAC gas furnace and other compatible 80% AFUE models. It seals the inspection opening on the burner compartment, allowing a technician to safely view the flame and confirm proper ignition and burner operation without exposing the cabinet interior. A cracked, missing, or hardened bushing can leak combustion products and let unfiltered air into the burner box, so replacing it with an exact-fit OEM part keeps the furnace inspectable and code-compliant.

Specifications

OEM Part Number: B1392139
Part Type: View Port / Sight-Glass Bushing (fitting)
Fits Model: AMS80403AXAC and compatible Goodman/Amana furnaces
Brand: Goodman (Amana family)
Application: Gas Furnace burner compartment
Material: Heat-resistant molded grommet

OEM vs. Generic

Generic bushings often use a looser tolerance that lets the sight glass rattle loose or fails to seal against combustion-chamber pressure. The genuine B1392139 is molded to Goodman's exact port dimensions for a tight, lasting seal and correct heat rating — the safest choice for a combustion component.

Installation Difficulty

Easy (1/5). Press-fit replacement; no tools or wiring required. Always shut off gas and power before servicing the burner compartment.
