The Goodman B1392139 View Port Bushing is a genuine OEM sight-port grommet for the AMVC80805CNBC 80% AFUE gas furnace. This bushing seals and frames the burner-compartment view port, allowing safe visual inspection of the flame and ignition sequence while helping maintain the sealed-combustion integrity of the burner box. A cracked or missing bushing can allow air leakage and obscure the flame view.
The OEM B1392139 is sized to press cleanly into the factory view-port opening for a snug, heat-tolerant seal. Generic grommets may not seat properly or withstand burner-compartment temperatures. For a correct, lasting seal, choose the OEM bushing.
Easy. Power off the furnace, remove the burner door, press out the old bushing, and press in the replacement. No tools or wiring required — one of the simplest furnace repairs.
