OEM Goodman 20201802 Condensate Drain Hose Tube

The Goodman 20201802 is a factory-original condensate drain hose tube for the GCH90904CXAB high-efficiency condensing gas furnace and compatible Goodman/Amana models. In a 90%+ AFUE furnace, combustion produces acidic condensate that must be routed away from the heat exchanger and collector box. This tube carries that condensate through the drain system, and a cracked, brittle, or clogged hose is a common cause of nuisance lockouts and water leaks around the furnace base.

Specifications

Type: Condensate drain hose / tube
Material: Molded flexible drain tubing
OEM Part Number: 20201802
Brand: Goodman (also fits equivalent Amana units)
Application: High-efficiency gas furnace, model GCH90904CXAB

OEM vs. Generic

The OEM Goodman 20201802 is molded to the exact length, bend, and fitting diameter of the factory drain routing, so it seats without kinking or strain on adjacent components. A generic equivalent hose can work for a general repair but may require trimming or extra clamps to match the original path.

Install Difficulty

Very Easy (1/5). Slip-on/clamped hose connection — pull the old tube, seat the new one, and secure the clamp. Under 10 minutes with no tools beyond a nut driver. Power the furnace off first and check for leaks after restart.
