The Goodman 20201901 Condensate Drain Hose Tube is a genuine OEM drain line built for the Goodman ACSH960704CXAA 96% AFUE condensing gas furnace and related Goodman/Amana models. This formed tube carries acidic condensate between the secondary heat exchanger, drain trap, and inducer, keeping the high-efficiency drainage system sealed and flowing. Swapping a hardened or clogged hose restores drainage and prevents pressure-switch lockouts and water leaks inside the cabinet.
This genuine Goodman OEM hose matches the factory length, diameter, and pre-shaped bends for your furnace's drain path. Generic replacements often kink or use the wrong bore, causing backups and inducer faults. OEM guarantees correct routing and a reliable, leak-free seal.
Easy. Power down the furnace, remove the old hose from its barbed fittings, and press the new tube onto the same ports. The job usually needs no tools and takes only a few minutes. Confirm the line is kink-free and draining before restoring power.
Disconnect power before servicing. Confirm compatibility using your furnace's full model and serial number.
