The Goodman 20171701 Condensate Drain Trap is a genuine OEM replacement for the GCH950905DXAD 95% high-efficiency gas furnace and compatible Goodman/Amana condensing models. The drain trap collects acidic condensate produced during high-efficiency combustion and channels it to the drain while maintaining a water seal that blocks flue gases from escaping into the living space. A cracked, clogged, or missing trap causes water leaks, pressure-switch faults, and lockout errors.
This OEM Goodman trap matches the factory port layout and float configuration exactly, so condensate drains correctly and pressure switches read properly. Generic traps often have mismatched inlet/outlet ports that create leaks or false pressure-switch trips. OEM ensures reliable drainage and safe flue-gas isolation.
Moderate — Power off, disconnect the condensate hoses and pressure-switch tubing, remove the old trap, and install the new one with a fresh water prime. Plan 30–45 minutes and confirm no leaks under operation.
