The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate drainage component engineered for the AMH950703BXAA gas furnace. It routes condensate away from the secondary heat exchanger and drain trap, keeping moisture out of the burner compartment and preventing overflow, corrosion, and nuisance safety-switch trips. Using the correct factory tube ensures a leak-free seal and proper drainage slope.
Generic drain tubing may not match the factory bend radius or connection diameter, leading to kinks, poor drainage, and leaks. This genuine OEM part is molded to the exact dimensions Goodman specifies, guaranteeing correct fit and reliable condensate flow the first time.
Easy (1/5). Slip-fit replacement — disconnect the old tube, seat the new one, and secure. Typically a 10–15 minute job for a homeowner or technician. Always shut off power and gas before servicing.
