The Goodman 20171701 Condensate Drain Trap is the genuine OEM trap assembly for the AMVC950453BXAE 96% AFUE two-stage variable-speed gas furnace. In a high-efficiency furnace, combustion produces acidic condensate that must drain away freely while the trap maintains a water seal that keeps flue gases from escaping through the drain line.
A cracked, clogged, or algae-fouled trap is a common cause of water leaks, pressure-switch faults, and furnace lockouts. Because the condensate is corrosive, traps eventually degrade and are best replaced as a complete assembly rather than repaired piecemeal.
OEM vs. Generic: The trap's port layout, internal baffles, and seal height are matched to this furnace's drain routing and pressure-switch tubing. Our OEM Goodman 20171701 drops in and seals correctly the first time. Universal traps often require adapters and can mis-seal, leading to recurring nuisance leaks and fault codes. OEM is the reliable fix.
Installation difficulty: Easy (2/5). Power down the furnace, disconnect the drain and pressure hoses, remove the old trap, flush the drain line, install the new trap, and prime it with water to establish the seal. Confirm no leaks on a heat cycle. Typically a 20-minute repair.
