The Goodman 20171701 Condensate Drain Trap is a genuine OEM component for the Goodman WFD195070S3BAB high-efficiency furnace and compatible WFD-series models. In a condensing furnace, the drain trap collects acidic condensate from the secondary heat exchanger and maintains a water seal that prevents flue gases from escaping into the drain line. A cracked, clogged, or improperly sealed trap can trigger pressure-switch faults, water leaks, and lockouts, so a correct OEM replacement keeps drainage flowing and the furnace running.
OEM vs. Generic: This authentic Goodman trap matches the exact port sizes, seal locations, and drain geometry of your furnace. Generic traps may not align with factory tubing or maintain the proper trap depth, causing leaks or nuisance pressure-switch trips. OEM fitment ensures a leak-free seal and preserves your warranty.
Installation difficulty: Easy to Moderate. Most technicians replace this trap in 20-30 minutes: shut off the furnace, disconnect the inlet and drain hoses, remove the mounting screws, and install the new trap with fresh water in the seal. Flushing the drain line at the same time helps prevent repeat clogs.
Genuine Goodman quality means dependable drainage. The 20171701 ships fast and installs to spec.
