Goodman B1392139 View Port Bushing

The Goodman B1392139 is a genuine OEM view port bushing engineered as a direct-fit replacement for the WFM18090S4BXCC gas furnace and other compatible Goodman/Amana models. This bushing seats in the combustion access panel to hold the sight glass, allowing safe visual inspection of the burner flame while maintaining a sealed combustion chamber. A cracked, brittle, or missing bushing can allow air leaks that disturb flame stability, so replacing it with the correct OEM part restores proper combustion draft and safety.

Specifications

Part number: B1392139
Type: View port / sight-glass bushing
Fits: Goodman WFM18090S4BXCC and compatible furnaces
Material: High-temperature molded grommet
Function: Seals and retains the combustion inspection port

OEM vs. Generic

Our OEM Goodman bushing matches the exact bore diameter and temperature rating of the factory component, ensuring a leak-free seal that generic universal grommets often cannot guarantee. Off-brand substitutes may shrink or deform at combustion-chamber temperatures. Choose OEM for guaranteed fit and long-term reliability around the burner assembly.

Installation Difficulty

Easy (1/5). Replacement takes only minutes — power down the furnace, remove the old bushing from the access panel, press the new B1392139 into place, and reseat the sight glass. No special tools required. Always shut off gas and electrical power before servicing.
