The Goodman B1392139 View Port Bushing is a genuine OEM replacement for the sight-glass viewing port on the AMH80604BNBB 80% AFUE gas furnace and compatible Goodman/Amana models. This bushing seals the inspection port that lets technicians confirm burner flame and ignition, keeping combustion-chamber pressure and airflow correct.

Specifications

OEM Part Number: B1392139
Type: View port / sight-glass bushing (fitting)
Fits Model: AMH80604BNBB
Brand: Goodman / Amana
Application: Gas furnace combustion inspection port

OEM vs. Generic

Our genuine OEM B1392139 is molded to factory tolerances for a leak-free seal and correct heat resistance. Generic bushings often shrink or harden near the heat exchanger, allowing pressure loss and nuisance flame-sensing faults. For a small-cost part that affects combustion safety, OEM is the smart choice.

Installation Difficulty

Easy (1/5). Press-fit replacement — power down the furnace, pop out the old bushing, and seat the new one. No tools or wiring required. Should take under 5 minutes for a qualified technician.
