The B1392139 is a genuine OEM view port bushing (sight-glass grommet) for the Goodman/Amana AMES800804CXAA gas furnace. It seals the inspection port on the burner or heat-exchanger compartment, letting technicians safely view the flame while blocking flue gases and combustion air leaks. A brittle or missing bushing can cause improper combustion readings and nuisance flame-sensor issues, so a clean seal matters.
The OEM B1392139 is molded to the exact port diameter and rated for the furnace's combustion-chamber temperatures, ensuring an airtight, heat-resistant seal. Generic grommets may be the wrong bore size, degrade under heat, or fall out — allowing air infiltration that skews flame behavior. For a leak-free seal that holds up over years of cycling, choose the OEM bushing.
Easy (1/5). The bushing presses into the view port opening by hand in under 5 minutes — no tools required. Shut off power and gas, remove the burner-compartment door, seat the new bushing firmly, and reinstall the door.
