The Goodman B1392139 View Port Bushing is the genuine OEM grommet that frames and seals the sight-glass viewing port on your AMES960603BNAA gas furnace. This small but important fitting lets you inspect the burner flame while keeping the combustion chamber sealed against air leaks. A brittle, missing, or melted bushing can allow flue gases to escape and disrupt combustion-air balance, so a fresh factory-spec seal keeps your furnace running safely and efficiently.
Because this bushing sits near the combustion area, temperature rating matters. The genuine Goodman OEM B1392139 uses the correct heat-resistant compound and outer-diameter dimension for a leak-free press fit. Generic rubber grommets may not tolerate the heat and can deform, shrink, or fall out over time.
Easy. A true 5-minute repair — pop the old bushing out of the panel opening and press the new one into place by hand. No tools needed. As always, shut off power and gas before opening any furnace panel.
