The B1392139 is a genuine Goodman view port bushing for the VMES960803BNAA modulating gas furnace. This bushing lines the combustion sight/inspection port, providing a clean, sealed opening through which a technician can observe the burner flame during operation. It protects the sheet-metal edge and helps maintain the cabinet seal around the viewing window.
A generic grommet may not match the port diameter, leaving gaps that compromise the cabinet seal or fall out over time. The genuine Goodman B1392139 is sized to the factory opening for a secure, lasting fit.
Easy (1/5). Press the bushing into the port until seated. No tools required. Suitable for any homeowner or technician.
Cut power to the furnace before servicing and confirm the correct port before installation.
