The Goodman 20171701 Condensate Drain Trap is a genuine OEM component for the Goodman GKS90703BXAH high-efficiency (90%+) gas furnace and other compatible Goodman/Amana models. In a condensing furnace, the drain trap collects acidic condensate from the secondary heat exchanger and inducer while maintaining a water seal that blocks flue gases from escaping into the cabinet. A cracked, dry, or clogged trap causes water leaks, inducer faults, pressure-switch lockouts, and no-heat calls. This factory replacement restores proper drainage and sealing.
The OEM Goodman trap matches the exact port geometry, orientation, and connection sizes of your furnace, ensuring a leak-free seal and correct pressure-switch operation. Generic universal traps may fit poorly and disturb the pressure-switch reference, causing nuisance lockouts. For condensing furnaces, OEM is the safe choice.
Rating: Moderate. Requires disconnecting condensate tubing and pressure-switch lines, then re-priming the trap with water. Turn off power before servicing. Estimated time: 30–45 minutes. Professional installation recommended.
