The Goodman 20171701 is the factory-original condensate drain trap for the AMH950905DXAC 95% high-efficiency furnace. In a condensing furnace, the secondary heat exchanger produces acidic condensate that must drain freely while the trap maintains a water seal against inducer pressure. A cracked, clogged, or mismatched trap causes water leaks, pressure-switch faults, and no-heat lockouts — making this an essential maintenance and repair part.
This genuine OEM trap matches the exact port sizing, height, and internal geometry the AMH950905DXAC drainage system relies on. Generic or universal traps frequently seal at the wrong level or use incompatible port diameters, leading to slow drainage and recurring pressure-switch trips. OEM ensures a leak-free, correctly sealed installation.
Difficulty: Easy. Power down the furnace, disconnect the condensate hoses, unclip or unscrew the old trap, then install and re-route the hoses. Flush the new trap with water to prime the seal. Usually a 15–20 minute job. Inspect all hoses for cracks while you are in there.
