Keep your high-efficiency furnace draining properly with the genuine Goodman 20171701 Condensate Drain Trap. Designed for the AMS951155DXAB and compatible Goodman/Amana 95%+ condensing furnaces, this OEM trap collects acidic condensate from the secondary heat exchanger and inducer, maintains the water seal that prevents flue-gas bypass, and routes drainage to the line. A clogged or cracked trap is a leading cause of pressure-switch lockouts and water leaks — a fresh OEM trap restores reliable operation.
The trap's internal geometry sets the water-seal height that the pressure switch depends on. The factory-genuine 20171701 matches port locations, seal depth, and inducer connections exactly. Generic traps can alter the seal and trigger phantom pressure-switch faults. OEM is strongly recommended here.
Moderate (3/5) — Requires disconnecting multiple condensate/drain hoses and the pressure-switch tubing, then re-seating with correct clamp orientation. Power down and prime the trap with water before restart. Flush the drain line and hoses while access is open.
