OEM Goodman Condensate Drain Trap for GKS90453BXAF Furnace — 20171701

Goodman 20171701 Condensate Drain Trap

The Goodman 20171701 is a genuine OEM condensate drain trap engineered for the GKS90453BXAF high-efficiency gas furnace and other compatible 90%+ AFUE Goodman/Amana models. During normal operation a condensing furnace produces acidic condensate that must be routed safely to a drain; this trap maintains the water seal that prevents flue gases and combustion air from escaping through the drain line while allowing condensate to flow freely. A cracked, clogged, or missing trap is a common cause of pressure-switch faults, nuisance lockouts, and water pooling around the unit.

OEM vs. Generic

This genuine OEM trap is molded to the exact port spacing and barb sizes of the factory drain assembly, so it seats without adapters or silicone workarounds. Aftermarket "universal" traps often require trimming or rerouting and can leak at the seams. Choosing the OEM part protects your warranty and ensures the pressure-switch tubing lines up correctly.

Installation Difficulty

Easy (1/5). 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. Most homeowners complete the swap in 15–20 minutes with basic hand tools. Always verify condensate flow and check for leaks before returning the unit to service.
