Genuine Goodman 20171701 Condensate Drain Trap

The Goodman 20171701 condensate drain trap is a factory-original assembly for the GCH90704CXAA high-efficiency condensing gas furnace. The trap collects acidic condensate from the secondary heat exchanger and inducer while maintaining a water seal that prevents flue gases and negative pressure from bypassing the drain system. A cracked, clogged, or dried-out trap is a leading cause of pressure-switch faults, water leakage, and lockout codes on 90%+ AFUE furnaces.

Specifications

OEM Part Number: 20171701
Type: Condensate drain trap assembly
Material: High-temperature, corrosion-resistant molded plastic
Function: Drains condensate; maintains flue-gas water seal
Equipment: 90%+ AFUE condensing gas furnace
Primary fit: Goodman GCH90704CXAA

OEM vs. Generic

The OEM Goodman drain trap matches the exact port layout, seal depth, and mounting of the factory unit, guaranteeing correct condensate flow and pressure balance. Generic traps often differ in port configuration and can cause improper drainage or pressure-switch errors. For condensing-furnace drainage, OEM fit prevents callbacks.

Installation Difficulty

Moderate (3/5). Power down the furnace, disconnect the condensate and pressure-switch tubing, remove the old trap, and install the new assembly—priming it with water to establish the seal. Confirm no leaks and clear operation before returning to service. Roughly a 20–30 minute job for a technician.
