The Goodman 20171701 Condensate Drain Trap is a genuine OEM part for the AMVC950704CXAA 96% AFUE condensing gas furnace and related Goodman/Amana high-efficiency models. In a condensing furnace, the secondary heat exchanger produces acidic condensate that must drain freely while the trap maintains a water seal that blocks flue gases from escaping into the cabinet. A cracked, clogged, or brittle trap causes water leaks, pressure-switch faults, and no-heat lockouts.
The trap's port layout, seal depth, and drain geometry are specific to Goodman's condensate routing and inducer pressure. Generic traps often don't align with the factory hoses or hold the correct water seal, leading to leaks or nuisance pressure-switch trips. The genuine OEM 20171701 installs to spec and maintains proper drainage and sealing.
Rated Moderate (3/5). Replacement requires disconnecting condensate hoses, priming the trap with water to establish the seal, and confirming free drainage. Always clear any blockage in the tubing while the trap is off. Service by a licensed HVAC professional is recommended.
