OEM Goodman Condensate Drain Trap for AMV90905DXBA — 20171701

The Goodman 20171701 Condensate Drain Trap is a genuine OEM replacement designed for the AMV90905DXBA high-efficiency gas furnace and compatible Goodman/Amana 90%+ AFUE models. In a condensing furnace, the drain trap captures acidic condensate from the secondary heat exchanger and inducer while maintaining a water seal that blocks flue gases from escaping into the living space. A cracked, clogged, or missing trap is a leading cause of pressure-switch lockouts and nuisance shutdowns.

OEM vs. Generic

This genuine OEM trap matches factory port geometry and seal depth exactly, so it seats correctly the first time and holds warranty compliance. Universal aftermarket traps often require adapter fittings and can leak or draw down the water seal, tripping the pressure switch. For a condensing furnace, OEM is the reliable choice.

Installation Difficulty

Rating: Easy (1/5). Power down the furnace, disconnect the drain hoses, remove the old trap, prime the new trap with water, and reconnect. Typically a 10–15 minute job with basic hand tools. No special skills required, though we recommend confirming proper drainage after startup.
