The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM drain line for the Goodman ACSH960704CXAA 96% AFUE condensing gas furnace and related Goodman/Amana models. This flexible tube routes acidic condensate between the secondary heat exchanger, drain trap, and inducer assembly. Replacing a cracked, brittle, or clogged hose restores proper drainage and clears nuisance pressure-switch lockouts.
This genuine Goodman OEM hose is pre-cut and formed to the exact length and bend radius for your furnace's drain routing. Generic tubing often has the wrong inside diameter or kinks at the bends, causing slow drainage, water backup, and pressure-switch faults. OEM ensures a leak-free, correctly routed fit.
Easy. Power down the furnace, slip the old hose off its barbed fittings, and press the new tube onto the same connections. No tools are typically required and the swap takes only a few minutes. Verify there are no kinks and that condensate flows freely before restoring power.
Disconnect power before servicing. Confirm compatibility using your furnace's full model and serial number.
