The Goodman 20171701 Condensate Drain Trap is a genuine OEM part built for the GCH950703BXAD 95% AFUE high-efficiency gas furnace and compatible Goodman/Amana models. In condensing furnaces, the drain trap safely channels acidic condensate away from the heat exchanger and secondary coil while maintaining a proper water seal that prevents flue-gas leakage. A cracked or clogged trap causes water backup, pressure-switch faults, and lockouts — this factory replacement restores correct drainage.
The genuine Goodman 20171701 matches the exact port spacing and hose-barb configuration of your furnace's condensate system. Generic traps often require adapters that leak or fail to hold a proper seal, triggering pressure-switch errors. OEM guarantees a clean, leak-free fit.
Rating: Easy (2/5). The trap disconnects from its drain hoses and mounts in minutes. Prime the trap with water after installation to establish the seal. Shut off power before servicing.
