The Goodman 20171701 is a genuine OEM condensate drain trap used on Goodman 90%+ AFUE furnaces including the GMS950453BXA. In a high-efficiency furnace, combustion produces acidic condensate that must drain away while the trap's water seal blocks flue gases from escaping into the cabinet. A cracked, clogged, or algae-fouled trap causes water leaks, pressure-switch faults, and ignition lockouts — a new trap restores proper drainage and a reliable seal.
The OEM 20171701 is molded to match the factory port locations and drain routing for a leak-free, drop-in fit. Our generic equivalent replicates the port pattern and seal geometry at a lower cost — a good value when an exact OEM match is not essential.
Moderate (2/5). Power down the furnace, disconnect the drain lines and inducer/collector-box tubing, remove the old trap, and install the new one — priming it with water to establish the seal. Roughly a 15–20 minute repair. Check all tubing for cracks while access is open.
Confirm port configuration matches your original before ordering.
