The Goodman B1392139 View Port Bushing is a genuine OEM fitting for the Goodman WFM18090S5CXCB gas furnace. This bushing seats in the burner compartment access opening and provides a clean, sealed sight port that lets a technician visually confirm burner flame and ignition through the panel without opening the cabinet. Though small, it maintains the compartment seal and protects the panel edge around the inspection opening.

Specifications

OEM Part Number: B1392139
Part Type: View Port Bushing / Sight-Glass Grommet
Compatible Model: WFM18090S5CXCB
Brand: Goodman
Equipment: Gas Furnace
Function: Sealed burner-inspection view port

OEM vs. Generic

Because this is a snap-fit sealing component, exact diameter matters. The OEM Goodman bushing snaps securely into the factory opening for a flush, retained fit. Off-brand grommets that are slightly under- or over-sized fall out or fail to seal, defeating the purpose of the port. OEM ensures a lasting, correct fit at a very low cost.

Installation Difficulty

Rating: Very Easy. With power off, press the old bushing out and snap the new one into the panel opening by hand — no tools required. A one-minute replacement suitable for any homeowner.
