The Goodman 20171701 is the genuine OEM condensate drain trap for the GKS90453BXAA 90%+ AFUE gas furnace and compatible GKS9-series models. In a high-efficiency condensing furnace, the secondary heat exchanger produces acidic condensate that must drain freely while the trap maintains a water seal that blocks flue gases from escaping into the airflow. A cracked, clogged, or dried-out trap is one of the most common causes of a furnace that short-cycles, throws a pressure-switch fault, or leaks water at the base.
This is the factory OEM Goodman trap, molded to the exact port spacing and barb sizes of the GKS90453BXAA cabinet. Aftermarket universal traps often require adapters, sit at the wrong height, or seal poorly against the collector box — the OEM part drops in without modification and preserves the manufacturer's condensate path.
Rated Easy (1 of 5). Shut off power and gas, disconnect the drain hoses, unclip or unscrew the old trap, prime the new trap with water, and reconnect. Typically 15–25 minutes with basic hand tools. Always follow Goodman service instructions and local code.
