The Goodman 20201901 is a genuine OEM condensate drain hose/tube for the GCH91155DXAA condensing gas furnace and compatible Goodman/Amana equipment. This tube carries acidic condensate from the secondary heat exchanger and collector box to the drain trap. Its factory bend radius and connection sizing are matched to the furnace cabinet, ensuring the condensate path stays clear and does not airlock — a frequent hidden cause of intermittent pressure-switch lockouts on high-efficiency furnaces.
The OEM 20201901 is pre-formed to the exact routing this chassis requires. Substituting generic tubing risks incorrect length or diameter, kinks, and slow drainage that lets water back up into the burner compartment. For a condensing furnace, matching the factory tube protects the heat exchanger and control electronics from moisture damage.
Very Easy (1/5). Disconnect the old hose at the trap and collector fittings, seat the replacement fully, and re-secure any clamps. Cut power before servicing, then verify unobstructed condensate flow and check every joint for leaks after the furnace restarts.
