This genuine OEM Goodman/Amana 20201802 condensate drain hose tube is a factory replacement for the AMVC951155DXAB modulating variable-speed gas furnace and other compatible Goodman and Amana models. It routes condensate away from the secondary heat exchanger and collector box, keeping the drain system clear and preventing water backup that can trip the pressure switch or cause nuisance lockouts.
We recommend the genuine OEM 20201802 because its molded bend radius and inside diameter match the furnace's drain trap and collector box connections exactly. Universal aftermarket hose can kink, leak at the fittings, or restrict flow — leading to callbacks. The OEM part seats correctly on the first attempt and preserves the manufacturer's condensate slope.
Easy (1/5). A simple push-fit replacement — disconnect the old hose, seat the new one on the barbed fittings, and confirm the clamps are secure. Typical replacement time is under 10 minutes with no special tools. Always shut off power and gas before servicing.
