The Goodman 20201901 is a genuine OEM condensate drain hose tube for the GCH950704CXAB and compatible Goodman/Amana condensing furnaces. This molded hose carries condensate between the collector box, drain trap, and drain line, formed to the exact length and bends required for this furnace cabinet so it seats cleanly without kinks. Replacing a cracked, hardened, or clogged hose restores proper drainage and prevents water leaks, pressure-switch faults, and heating lockouts.
The OEM 20201901 arrives pre-shaped to the factory routing with the correct diameter and fitting geometry, eliminating guesswork. Generic hose must be cut and bent to fit and can kink at tight cabinet turns, restricting flow. OEM ensures reliable drainage and a correct seal.
Easy. Pull the old hose off its fittings, route the replacement along the same path, and reattach any clamps — about 5–10 minutes. Confirm the drain flows freely before returning the furnace to service.
