The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate hose for AMS950905DXA high-efficiency gas furnaces. This tube links the drainage components — collector box, trap, and inducer ports — routing acidic condensate safely out of the furnace. It is factory-formed to the exact length and shape required for this model, ensuring a sealed, kink-free connection.
When drain hoses harden, split, or become clogged with sediment, the furnace can leak water, back up condensate, or lock out on a pressure-switch fault. Installing the correct OEM hose restores reliable drainage and quiet, trouble-free operation.
OEM vs. Generic: Because this hose is pre-bent for the AMS950905DXA's internal routing, it seats without adapters or forcing. Generic tubing often has the wrong diameter or wall stiffness, causing leaks and repeat service calls. Choose OEM for a guaranteed fit.
Install Difficulty: Easy (⭐☆☆☆☆). Push the hose onto the drainage ports, secure clamps, and confirm the run slopes to the drain. Always shut off power to the furnace before servicing.
