The Goodman 20171701 Condensate Drain Trap is a genuine OEM replacement part engineered for the AMH950453BXAD high-efficiency gas furnace. In condensing (90%+ AFUE) furnaces, the drain trap safely routes acidic condensate away from the heat exchanger and secondary coil while maintaining a water seal that blocks flue gases from escaping back into the cabinet. A cracked, clogged, or brittle trap is one of the most common causes of pressure-switch lockouts and standing-water error codes.
Our OEM option is the exact factory part, guaranteeing correct port geometry, seal depth, and chemical resistance to acidic condensate. Aftermarket generic traps may fit dimensionally but often use lower-grade plastics that warp or leak over time. For a sealed-combustion furnace, we strongly recommend OEM to protect the heat exchanger warranty.
Easy (1/5). Typically a snap-fit or clamped connection. Power off the furnace, disconnect the drain lines, swap the trap, prime it with water, and reconnect. Most homeowners complete this in under 20 minutes with basic hand tools.
