The Goodman B1392139 View Port Bushing is the genuine OEM sight-glass grommet for WFD18070S3AXCB furnaces. It seals the burner inspection port so technicians can safely view the flame while keeping combustion gases and drafts contained. A cracked or missing bushing lets air leak into the burner box, disrupting flame stability and safe operation.

Specifications

OEM part number: B1392139

OEM vs. Generic

The genuine Goodman bushing is molded to the exact port diameter and rated for the temperatures found at the burner box. Generic grommets may not seal fully or can degrade near the flame. For a safety-related combustion component, the OEM part is the right choice.

Install Difficulty

Easy. Press the old bushing out and snap the new one into the port — under 5 minutes, no tools required. Cut power to the furnace and confirm the burners are cool before servicing.
