The Goodman 20201901 is a factory OEM condensate drain hose tube engineered for the AMVC950905CXAA modulating variable-speed gas furnace and compatible Goodman/Amana models. This flexible tube routes acidic condensate away from the secondary heat exchanger and collector box to the drain trap, protecting internal components from moisture damage, corrosion, and nuisance lockouts.
When a furnace short-cycles, throws a pressure-switch fault, or leaks water at the base, a cracked, brittle, or clogged drain tube is a common culprit. Replacing it with the exact OEM part restores proper drainage and keeps your high-efficiency furnace running reliably through the heating season.
Generic universal hose may not match the factory bend radius or fitting diameters, leading to kinks and leaks. This genuine OEM tube is molded to the exact specification, ensuring a leak-free, drop-in fit with no guesswork.
Easy (1/5) — Typically a 10-minute swap. Power down the furnace, disconnect the old tube from the collector box and trap, and slide the new one into place. Clear any blockage in the trap while you're there.
