The Goodman 20201901 condensate drain hose tube is a genuine OEM replacement line for the AMVM960805CXAA modulating high-efficiency furnace and compatible Goodman/Amana models. Preformed to the correct length and shape, this tube routes condensate through the drainage system while resisting the mildly acidic condensate produced by 90%+ AFUE combustion. Replacing a cracked, clogged, or hardened hose restores proper drainage and clears water-related lockouts.
Because this hose is factory-formed with the exact bends your furnace requires, it seats securely and holds its routing without sagging or kinking. Substituting straight generic tubing often forces tight bends that restrict flow and back up condensate. The OEM 20201901 keeps the drain path to specification and preserves your warranty coverage.
Easy (1 of 5). Shut off power to the furnace, release any clamps, pull the old hose from its fittings, and press the replacement fully onto each barb. Confirm the tube keeps a continuous downhill slope to the trap or drain. Typically 10–15 minutes with no special tools; check for leaks on the next heat cycle.
Install the genuine Goodman OEM drain hose and drain worry-free.
