The Goodman B1392139 View Port Bushing is a genuine OEM sight-glass grommet for the Goodman/Amana WFM18090S4BXCB furnace and compatible models. This small but important part seals the flame-observation port on the burner or blower access panel, letting technicians safely inspect the flame while maintaining the panel's seal and preventing air leakage or flame roll-out exposure.

Over time the original bushing hardens, cracks, or falls out, leaving an open port that disrupts combustion-air pressure and pulls the panel out of spec. This factory-molded replacement restores a tight, heat-resistant seal at the exact port diameter.

Specifications

Type: View / sight port bushing (grommet)
Fits: Goodman/Amana WFM18090S4BXCB and compatible furnaces
Heat-resistant molded construction
Direct OEM snap-in fit at the factory port diameter

OEM vs. Generic

Generic grommets rarely match the port diameter and can loosen under repeated thermal cycling. This genuine OEM B1392139 snaps in for a leak-free, heat-rated seal at pennies of cost — cheap insurance against combustion-air and safety-panel problems.

Install Difficulty

Very Easy (1 of 5). Push out the old bushing and snap the new one into the port. No tools required. Under 5 minutes. Ideal to keep on hand as a spare during any furnace tune-up.
