The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube engineered for the AMVM961155DXBA modulating gas furnace and other compatible Goodman and Amana high-efficiency furnace models. This flexible drain tube routes condensate away from the secondary heat exchanger and collector box to the drain trap, preventing water backup that can trigger pressure-switch faults or nuisance lockouts.
The genuine OEM 20201902 is molded to the exact length and inner diameter Goodman specifies, ensuring a leak-free press fit at both connection points. Generic aftermarket tubing is often cut to approximate lengths and may kink or slip off barbed fittings, causing condensate leaks and water damage. For reliable drainage, the factory OEM part is recommended.
Easy (1/5) — Slip-on replacement requiring no tools. Power down the furnace, disconnect the old hose at each fitting, seat the new tube, and confirm a snug connection. A basic DIY repair for most homeowners.
