The Goodman 20171701 is a genuine OEM condensate drain trap for the ACVC950915DXAB 96% AFUE high-efficiency gas furnace. As a condensing furnace cools flue gases, it produces acidic condensate that must drain away safely. This trap maintains the water seal that lets condensate flow out while blocking flue gases from escaping into the cabinet. A cracked or clogged trap causes water leaks, pressure-switch faults, and furnace lockouts.
The OEM 20171701 matches the exact port layout, fitting sizes, and seal geometry of this furnace, so it connects without adapters and seals correctly the first time. Generic universal traps often require modification and can leak or fail to hold proper pressure, triggering nuisance pressure-switch trips. OEM ensures a drop-in, leak-free fit.
Moderate (3/5) — Disconnect the drain tubing, remove and clean or replace the trap, then reconnect and prime with water. Roughly 20–30 minutes. Cut power before servicing and check for leaks after refilling the trap.
