Overview

The Goodman B1392139 is a genuine OEM view-port bushing for the WFM18045S3AXCB furnace. This small but important grommet seats in the burner-compartment observation port, giving a clean, sealed opening through which the flame and ignition sequence can be inspected during service. Because it maintains the pressure boundary of the burner box, a cracked, missing, or hardened bushing can allow air leakage that disturbs the flame pattern and flame-sensor reading. Installing the correct OEM bushing keeps the sight port sealed and serviceable.

Specifications

Type: view / sight port bushing (grommet)
Fits: Goodman WFM18045S3AXCB furnace
OEM part number: B1392139
Location: burner / flame observation port
Material: heat-resistant molded bushing
Function: seals and frames the inspection opening

OEM vs. Generic

The OEM Goodman bushing is molded to the exact port diameter and heat rating of the original, so it snaps in flush and holds its seal near the burner heat. Generic grommets often differ in outside diameter or temperature tolerance, leading to a loose fit or premature hardening. For a part this inexpensive, OEM removes any guesswork.

Install Difficulty

Easy. A quick push-in replacement — pop the old bushing out and seat the new one in the port. Under 5 minutes, no tools required. Disconnect power before opening the burner compartment.
