The Goodman 20171701 Condensate Drain Trap is a genuine OEM component engineered for the GKS91155DXAB high-efficiency gas furnace and other compatible Goodman GKS9-series models. This trap captures and channels condensate away from the heat exchanger and inducer assembly while maintaining a water seal that blocks flue gases from escaping into the cabinet — a critical safety and performance function in any 90%+ AFUE condensing furnace.
Our OEM Goodman trap is molded to exact factory port spacing and seal tolerances, guaranteeing a leak-free fit and full compatibility with the factory drain routing. Generic aftermarket traps are lower cost but may require adapters, use thinner walls, and are not backed by Goodman fit specifications. For a safety-critical condensate seal, OEM is strongly recommended.
Easy (1/5). Disconnect the inlet and outlet drain lines, remove the old trap, prime the new trap with water to establish the seal, and reconnect. Basic hand tools only; typically completed in under 15 minutes. Always cut power to the furnace before servicing.
