The Goodman 20171701 is a genuine OEM condensate drain trap for the GMV950704CXBB and compatible GMV95-series 96% AFUE furnaces. High-efficiency furnaces produce acidic condensate that must drain freely while the trap's water seal blocks flue gases from escaping into the cabinet. A cracked or clogged trap causes water leaks, pressure-switch lockouts, and error codes tied to condensate backup.
The OEM Goodman 20171701 matches the factory port spacing and inlet/outlet sizing for a drop-in fit with no adapters. Our generic equivalent provides the same functional trap at a value price for out-of-warranty service. OEM is recommended when exact port alignment matters for your cabinet layout.
Rated Easy (2/5). Power off the furnace, disconnect the condensate hoses, remove the old trap, and install the new one. Prime the trap with water before restarting so the flue-gas seal is established. Confirm free drainage and check for leaks after start-up.
Compatible replacement part; verify hose routing against your unit's installation manual.
