The Goodman 20171701 is a genuine OEM condensate drain trap engineered for the AMVC950905CXBA variable-speed, high-efficiency gas furnace. In a 95%+ AFUE condensing furnace, the secondary heat exchanger produces acidic condensate that must drain freely while maintaining a water seal that blocks flue gases from escaping into the cabinet. This factory trap keeps that seal intact, protecting combustion safety and preventing nuisance pressure-switch lockouts caused by improper drainage.
Genuine OEM traps match the exact port geometry, float behavior, and seal height of the original, so the furnace's pressure-switch timing stays within spec. Generic universal traps often require adapters and can trip the low-pressure switch. Choose OEM for guaranteed fit and reliable long-term drainage.
Most homeowners and technicians can swap this trap in 15–30 minutes. Power down the furnace, disconnect the condensate lines, remove the old trap, install the new 20171701, prime it with water to establish the seal, and reconnect. Always verify local codes and manufacturer instructions.
