OEM Goodman 20201902 23" Condensate Drain Hose Tube

The Goodman 20201902 is a factory-original 23-inch condensate drain hose tube for the GCH90904CXAB high-efficiency condensing gas furnace and compatible Goodman/Amana models. Its longer length spans from the collector box or secondary heat exchanger to the condensate trap and drain, keeping acidic combustion moisture moving cleanly out of the furnace. A brittle or blocked drain tube is a frequent cause of pressure-switch lockouts and standing water at the furnace base.

Specifications

Type: Condensate drain hose / tube
Length: 23 inches
Material: Molded flexible drain tubing
OEM Part Number: 20201902
Brand: Goodman (also fits equivalent Amana units)
Application: High-efficiency gas furnace, model GCH90904CXAB

OEM vs. Generic

The OEM Goodman 20201902 arrives pre-cut to the correct 23" length with the factory bend and fitting diameter, so it drops in without kinking. A generic equivalent can be trimmed to length for budget repairs but requires careful sizing to keep a continuous downhill slope for proper drainage.

Install Difficulty

Very Easy (1/5). Clamped hose connection, roughly 10 minutes. Shut off furnace power, remove the old 23" tube, route and clamp the new one along the same path, then confirm free drainage and no leaks after restart.
