The Goodman 20171701 Condensate Drain Trap is a genuine OEM replacement for the Amana/Goodman AMVM961155DXBA high-efficiency condensing furnace. In a 96% AFUE furnace, the secondary heat exchanger produces acidic condensate that must drain freely while the trap maintains a water seal — blocking flue gases from escaping through the drain line and preventing pressure-switch faults. A cracked or clogged trap is a common cause of nuisance lockouts.
The genuine OEM trap matches the factory port locations, float, and seal geometry exactly, so it drops into the existing plumbing without adapters. Generic traps frequently require re-plumbing and may not maintain the correct water column, risking flue-gas leakage and error codes. The OEM part is the safe, reliable choice.
Difficulty: Easy to Moderate. Power down the furnace, disconnect the drain hoses, remove the old trap, and prime the new trap with water before reconnecting. Most handy owners can complete this, though we recommend a technician verify drainage and pressure-switch operation afterward.
