The Goodman 20171701 Condensate Drain Trap is a genuine OEM assembly for the GMH951155DXAG 95% high-efficiency gas furnace. This trap collects acidic condensate from the secondary heat exchanger and routes it to the drain while maintaining a water seal that blocks flue gases from escaping into the cabinet. A cracked, clogged, or algae-fouled trap causes water leaks, pressure-switch faults, and nuisance lockouts — replacing it with the factory part restores proper condensate flow and draft.

Category: Drain — Condensate Trap Assembly
Material: Corrosion-resistant molded plastic
Function: Condensate collection + flue-gas water seal

OEM vs. Generic

OEM (20171701): Molded to match the furnace's drain ports and pressure-switch tubing connections exactly — a direct, no-adapter fit. Recommended.

Generic: Universal traps exist but rarely align with all factory tube ports; expect fittings and modifications. Best for experienced techs only.

Installation Difficulty

Moderate (3/5). Power off the furnace, disconnect the drain and pressure-switch hoses, unclip the old trap, and prime the new one with water before reconnecting. Roughly 30 minutes. Verify all hoses seat fully to avoid pressure-switch faults.
