The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate line built for AMVC950905DXAB modulating condensing furnaces. This tube channels condensate between the collector box, trap, and drain ports, keeping the water seal intact and the secondary heat exchanger draining freely. A cracked or clogged hose can trigger pressure-switch lockouts and water leaks inside the cabinet.
This factory OEM hose is pre-shaped to the exact length and fitting size your furnace requires. Generic tubing frequently kinks, leaks at the barbs, or blocks proper drainage. Installing the 20201901 guarantees a clean, leak-free fit and protects your warranty.
Difficulty: Easy (1/5). Turn off power, remove the old hose from both fittings, and push the new 20201901 fully onto each barb. Confirm the routing is kink-free and matches the original path. Replacement takes about 10 minutes with no special tools.
