The Goodman 20171701 Condensate Drain Trap is a genuine OEM replacement designed for the Goodman GCH950905DXAC 95% AFUE gas furnace and compatible condensing furnace models. As a high-efficiency furnace produces liquid condensate during combustion, this trap maintains the required water seal that prevents flue gases from escaping into the drain line while allowing condensate to flow to the drain. A cracked, clogged, or brittle drain trap is a leading cause of nuisance lockouts and water leaks around the furnace base.
This is the factory OEM trap, molded to the exact port spacing and outlet dimensions of your Goodman furnace cabinet. Generic universal traps often require adapters, may not seat correctly against the collector box, and can leak at the connection points. The OEM part drops in with no modification and preserves your furnace warranty coverage.
Easy (1 of 5) — A basic DIY replacement. Power down the furnace, disconnect the inlet and outlet hoses, remove the old trap, prime the new trap with water to establish the seal, and reconnect. Typical time is 15–20 minutes with no special tools. If your furnace is under warranty, confirm whether service must be performed by a licensed technician.
