The Goodman 20171701 is a genuine OEM condensate drain trap built for the AMV90453BXBB high-efficiency condensing furnace. In a 90%+ AFUE furnace, cooled flue gases release acidic condensate that must be drained safely. This trap holds a water seal that lets condensate flow out while blocking flue gases from escaping into the cabinet, protecting both the equipment and indoor air quality.
The OEM 20171701 is molded to the exact port spacing, hose barb sizes, and mounting geometry of the AMV90453BXBB. Generic traps rarely match the multi-port layout used on Goodman condensing furnaces, risking leaks or improper drainage. Choosing OEM ensures a leak-free seal on the first install.
Because this is a factory-shaped drainage component, the OEM part is the reliable choice — aftermarket substitutes often force adapter fittings and added leak points.
Easy to Moderate (2/5). Power down the furnace, disconnect and drain the condensate hoses, swap the trap, and reconnect. Prime the trap with water before restart. Basic hand tools only.
