The Goodman B1392139 View Port Bushing is a genuine OEM grommet that seats in the burner-compartment observation opening of AMEC800805CNAA gas furnaces. It provides a clean, heat-resistant seal around the sight-glass port so technicians can safely observe the flame while maintaining proper compartment pressure. A cracked or missing bushing can cause air leakage and nuisance flame-sensing issues, so replacing it keeps combustion diagnostics accurate.
This OEM Goodman bushing is molded to the exact inner and outer diameters of the factory port. Generic grommets are frequently a loose or oversized fit that pops out under vibration or fails to seal against the panel. The OEM part snaps in securely and is rated for the temperatures found in the burner box.
Easy. This is a snap-in part that installs in under five minutes with no tools. Turn off power and gas, remove the old bushing from the port opening, and press the new one into place until it seats fully. A perfect low-cost part to replace during routine furnace maintenance.
