The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube engineered for GCH950904CXAD gas furnaces and compatible Goodman/Amana models. It routes condensate away from the heat exchanger and inducer assembly, protecting internal components from moisture damage and corrosion. A worn, cracked, or clogged drain hose is a leading cause of nuisance shutdowns and water leaks — replacing it with the exact OEM part restores proper drainage and reliable operation.
Generic drain tubing is often cut to approximate lengths and may not seat correctly at the drain trap, leading to leaks. This genuine OEM 20201902 is pre-sized and material-matched to Goodman's specification, ensuring a leak-free, drop-in fit the first time.
Easy (DIY-friendly). Slip off the old hose, route the new one, and secure the clamps — typically a 10-minute job with no special tools. Always shut off power and gas before servicing.
