The Goodman B1392139 View Port Bushing is the genuine OEM sight-glass grommet used on AMEC800804CNAB and related Amana/Goodman 80% AFUE gas furnaces. This small but essential fitting seals the inspection port on the burner compartment, letting technicians safely view flame ignition and rollout while keeping the combustion cabinet properly closed. A cracked, brittle, or missing bushing can cause air leaks and failed flame observation during service.

Specifications

Part type: View port / sight-glass bushing (grommet)
OEM part number: B1392139
Compatible model: AMEC800804CNAB
Brand: Goodman / Amana
Material: High-temperature heat-resistant grommet
Application: 80% AFUE upflow/horizontal gas furnace

OEM vs. Generic

The OEM Goodman B1392139 is molded to exact factory tolerances for a leak-free press fit and rated for sustained combustion-chamber heat. Generic aftermarket bushings often use lower-grade rubber that hardens and shrinks near the burner box, leading to premature failure. For a furnace fitting exposed to heat cycling, we recommend the OEM part.

Install Difficulty

Easy (1/5). Power down the furnace, pop out the old bushing, and press the new one into the port opening. No tools or special skills required — typically under 5 minutes.

All installations of gas furnace components should be performed by a qualified HVAC technician in accordance with local codes.
