Goodman B1392139 View Port Bushing

The B1392139 is a genuine Goodman OEM view port bushing designed for the AMVM970804CNBA modulating, variable-speed gas furnace. This small but critical rubber/nylon grommet seats the burner sight-glass window in the combustion housing, sealing the inspection port so you can safely observe flame ignition and burner operation without allowing flue gases or air leaks around the opening.

Specifications

Part type: View port / sight-glass bushing (grommet)
OEM part number: B1392139
Compatible model: AMVM970804CNBA (AMVM97 series)
Equipment: 80,000 BTU modulating condensing furnace
Material: Heat-resistant molded polymer
Fit: Direct OEM replacement — no modification required

OEM vs. Generic

This is the genuine Goodman OEM component, molded to exact factory tolerances so the sight glass seats and seals correctly. Generic or universal grommets often fit loosely, distort under combustion-chamber heat, and can compromise the flue seal. For a furnace inspection port, an exact fit matters — choose OEM.

Installation Difficulty

Easy (1/5). Power down the furnace, pop the old bushing out of the housing opening, press the new B1392139 into place, and reseat the sight glass. No tools required. Always cut power at the disconnect before servicing.

Backed by fast shipping from National HVAC Parts. Verify your model number before ordering to ensure exact fit.
