The Goodman 20201901 is a genuine OEM condensate drain hose tube for the Amana/Goodman AMVM961155DXAA modulating condensing furnace. This is a larger primary drain run in the furnace's condensate system, carrying acidic combustion condensate from the collector box and drain trap safely out of the cabinet. The factory-molded shape follows the exact internal routing of the AMVM96 chassis for a secure, leak-free fit.
Because this hose spans a longer, multi-bend path, generic tubing is especially prone to kinking and improper slope — both of which trap condensate and cause pressure-switch faults. The genuine 20201901 holds the correct bends and length, protecting drainage and avoiding nuisance lockouts.
Easy (2/5). Plan on 10–15 minutes: disconnect power, photograph the routing, release each clamp along the run, remove the old hose, and seat the new one on the same fittings. Verify continuous downhill slope, no kinks, and clear drainage before returning to service.
A blocked or collapsed drain line is a leading cause of furnace water leaks and repeat shutdowns — replace worn condensate hoses promptly.
