OEM Goodman Condensate Drain Trap for AMH950905CXAC — 20171701

Goodman 20171701 Condensate Drain Trap

The Goodman 20171701 is a genuine OEM condensate drain trap for the AMH950905CXAC 95% high-efficiency gas furnace. In a condensing furnace, the secondary heat exchanger pulls latent heat from the flue gas, producing acidic condensate that must drain away. The trap maintains a water seal that lets condensate exit while blocking flue gases and inducer pressure from escaping through the drain line. A cracked, clogged, or missing trap causes pressure-switch faults, water leaks, and nuisance lockouts.

OEM vs. Generic

The OEM Goodman trap matches the exact port locations, hose sizes, and internal seal height the AMH950905CXAC drainage system needs, so it maintains proper pressure balance across the inducer. Generic universal traps often have different port geometry and can leak or fail to hold the seal, triggering intermittent pressure-switch trips that are maddening to diagnose. For a condensing furnace, OEM fit is worth it.

Install Difficulty

Moderate (3/5). Power down, catch residual water, disconnect the condensate and pressure hoses, unclip or unbolt the old trap, and install the new one. Prime the trap with water before startup so the seal is intact, then verify no leaks and that the pressure switch closes on a call for heat. Allow 30–45 minutes.
