The B1392139 View Port Bushing is a genuine Goodman replacement component engineered for the ADSS801005CXAC gas furnace and compatible Goodman/Amana furnace platforms. This small but essential grommet seats into the burner compartment sight-glass opening, holding the view port lens securely in place while sealing the cabinet against air leakage and combustion-gas escape. A cracked, brittle, or missing bushing can allow the viewing lens to fall out, letting conditioned air bypass the heat exchanger and making it impossible to safely observe the burner flame during service.
The OEM Goodman B1392139 is molded to the exact port diameter and rated for the elevated temperatures inside the burner box, ensuring a leak-free, drop-in fit. Generic universal grommets may loosen, deform, or fail to seal properly under repeated thermal cycling. For a reliable, code-conscious repair, OEM is strongly recommended.
Easy (1/5). Press-fit replacement — no tools or wiring required. Power down the furnace, remove the old bushing, and seat the new one in the port. Typical replacement takes under five minutes.
