Goodman B1392139 View Port Bushing

The B1392139 view port bushing is a genuine OEM sight-glass fitting used on the Goodman WFM18140S5DNCC gas furnace. It seats in the burner compartment access panel so technicians can safely observe the flame pattern and ignition sequence without opening the cabinet. A cracked, clouded, or missing bushing is a common cause of failed flame-inspection checks — replacing it restores a clear, sealed viewing port and keeps the combustion area properly isolated.

Specifications

  • Part number: B1392139
  • Type: View port / sight-glass bushing
  • Fits: Goodman WFM18140S5DNCC and compatible furnace platforms
  • Material: Heat-resistant molded bushing
  • Application: Burner compartment flame-view port

OEM vs. Generic

This is a genuine Goodman OEM bushing engineered to the exact bore and flange dimensions of the factory panel opening. Generic aftermarket bushings often run slightly undersized or use lower-temperature plastics that yellow and crack near the burner box. For a fitting this inexpensive, OEM is the smart choice — an ill-fitting part can whistle, leak flue gases, or fall out.

Installation Difficulty

Easy (DIY-friendly). Power down the furnace, press or thread the old bushing out of the access panel, and seat the new one until flush. No special tools required. Estimated time: under 5 minutes. Always confirm power is off at the disconnect before servicing.
