Goodman B1392139 View Port Bushing

The B1392139 is a genuine OEM Goodman view port bushing designed for the AMVC80604BNBD gas furnace and compatible Goodman and Amana units. This bushing seals the sight-glass inspection opening on the burner/combustion compartment, letting a technician safely observe the burner flame while keeping the combustion area sealed against air leaks. A brittle, cracked, or missing bushing can allow drafts that disrupt the flame pattern and trip the flame sensor — a small part that protects reliable ignition.

Specifications

OEM Part Number: B1392139
Part Type: View Port Bushing / Sight-Glass Grommet
Equipment: Gas Furnace
Primary Fit: Goodman AMVC80604BNBD
Also Fits: Select Goodman & Amana furnace models
Material: High-temperature molded grommet

OEM vs. Generic

Genuine OEM ensures the bushing matches the port diameter exactly for a snug, sealed press-fit. Generic grommets may not seat tightly, leaving gaps that let combustion-air leak past — undermining flame stability. At this price point, OEM is the clear pick.

Installation Difficulty

Very easy — DIY friendly (1 of 3). No tools required in most cases: power off the furnace, pop out the old bushing, and press the new one into the port. Under 10 minutes. Always cut power at the disconnect before opening the burner compartment.
