The Goodman 20171701 Condensate Drain Trap is a genuine OEM replacement engineered for the GMH950703BXAC high-efficiency gas furnace and other compatible Goodman/Amana 90%+ AFUE condensing models. This drain trap captures and channels acidic condensate away from the secondary heat exchanger, preventing water backup, flue-gas recirculation, and pressure-switch faults that can lock out your furnace.
Our OEM version is the exact factory-molded part with correct port geometry and sealing surfaces — a guaranteed fit that maintains your furnace's pressure-switch calibration. Generic aftermarket traps are more affordable but may require adapter fittings and can subtly shift condensate flow, risking nuisance lockouts. For a condensing furnace, we recommend OEM for reliable drainage.
Easy (2/5). Most homeowners can swap this trap in 15–30 minutes with basic hand tools. Shut off power and gas, disconnect the inlet and outlet hoses, remove the old trap, prime the new trap with water, and reconnect. Always confirm proper drainage before returning the unit to service.
Backed by genuine Goodman quality. In stock and ready to ship.
