The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM part for the Amana/Goodman AMVM961155DXBA high-efficiency condensing furnace. This pre-formed hose routes acidic condensate between the heat exchanger collector box, pressure switch ports, and drain trap. Because it is molded to a specific length and bend, it seats without kinks or strain — preventing the trapped-water blockages and air leaks that trigger pressure-switch lockouts.
The OEM hose is molded to the exact length and radius your furnace requires, so it connects the collector box, switch, and trap without modification. Generic bulk tubing must be cut to length and can kink or pull loose at the fittings, causing leaks and false error codes. The genuine part guarantees a clean, correct routing.
Difficulty: Easy. With the furnace powered off, pull the old hose from its barbed fittings and press the replacement onto the matching ports. No tools are typically required. Verify the drain path is clear and confirm normal operation when finished.
