The Goodman 20171701 Condensate Drain Trap is a genuine OEM component for the GMV951155DXA and related 95%+ AFUE Goodman/Amana condensing furnaces. In a high-efficiency furnace the secondary heat exchanger produces acidic condensate; this trap collects and drains that liquid while maintaining the water seal that prevents flue gases and pressure loss from escaping the drain line. A cracked or clogged trap causes pressure-switch faults, water leaks, and lockouts.
The OEM 20171701 matches the exact port spacing, inlet/outlet diameters, and seal geometry of the GMV951155DXA cabinet. Universal traps often require adapters that introduce leak points and can trigger false pressure-switch trips. OEM ensures a factory-correct fit and proper condensate flow.
Moderate (2/5). Requires disconnecting condensate hoses, removing the old trap, and priming the new trap with water to establish the seal. Inspect and flush the drain line while access is open. Shut off power before service.
