The Goodman 20171701 condensate drain trap is a genuine OEM replacement engineered for the ACV90704CXBA high-efficiency gas furnace and other compatible Goodman/Amana 90%+ models. The drain trap collects acidic condensate produced during combustion and routes it safely to the drain line while maintaining the water seal that blocks flue gases from escaping back into the cabinet. A cracked, clogged, or missing trap is one of the most common causes of furnace lockouts and water leaks at the base of the unit.
This is a factory OEM Goodman trap built to the exact port spacing, seal geometry, and chemical-resistance rating of the original. Generic or universal traps can leak at the gaskets, fail to seat against the collector box, or degrade quickly from acidic condensate — risking nuisance shutdowns and water damage. For a guaranteed seal and full warranty compatibility, the OEM part is the safe choice.
Easy (Beginner). Power down the furnace, disconnect the inlet and outlet hoses, remove the old trap, install the new 20171701, reconnect the hoses, and prime the trap with water before restarting. Typically a 15–20 minute job with basic hand tools.
