The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube engineered as a direct-fit replacement for the AMH950453BXAB 95%+ AFUE gas furnace and other compatible Goodman/Amana high-efficiency models. As a condensing furnace, this unit produces liquid condensate during normal operation, and this flexible drain tube routes that moisture safely away from the heat exchanger and inducer assembly to your drain trap or floor drain.
Using the correct OEM-length hose prevents kinks, sagging, and standing water that can trigger nuisance pressure-switch lockouts and drain-blockage faults.
This is a factory OEM component cut to the exact length and inner diameter Goodman specifies for the AMH950 platform. Generic universal hose may fit loosely or require trimming, increasing the risk of leaks at the barbed connections. The genuine 20201902 seats correctly the first time and protects your equipment warranty.
Easy (1/5). A basic DIY repair — power down the furnace, slip the old hose off the drain fittings, and press the replacement into place. No special tools required; typically completed in under 10 minutes. Always confirm your model and part number before ordering.
