Goodman B1392139 View Port Bushing

The B1392139 is a genuine Goodman OEM view port bushing, a direct-fit replacement for the WFM18090S5CXCC and compatible Goodman/Amana furnaces. This small grommet-style bushing seals the burner-compartment sight port, letting a technician visually confirm the flame while maintaining the cabinet seal on high-efficiency furnaces. Over time the bushing can become brittle, cracked, or lost, which allows air leakage around the inspection port and can affect combustion-air balance. Replacing it restores a clean, sealed viewing window.

Specifications

OEM Part Number: B1392139
Type: View port bushing / sight-glass grommet
Fits: Goodman WFM18090S5CXCC and compatible Goodman/Amana furnaces
Material: High-temperature molded bushing
Function: Seals and frames the burner inspection port

OEM vs. Generic

Because this bushing seats into a precise opening in the burner box, the OEM part guarantees a correct, airtight press fit. Generic grommets rarely match the diameter and depth, leading to air leaks or a bushing that falls out. For such an inexpensive part, the genuine OEM piece is always the right call.

Installation Difficulty: Very Easy (DIY-friendly)

No tools required in most cases — simply press the old bushing out and snap the new one into the port opening. A 2-minute replacement. Always de-energize the furnace before opening the burner compartment.
