The Goodman 20201902 is a genuine 23-inch condensate drain hose tube engineered as a direct-fit replacement for the AMVM961005DXBA modulating gas furnace and other compatible Goodman/Amana 96% AFUE models. This flexible drain line routes condensate away from the secondary heat exchanger and collector box to the drain trap, preventing water backup, nuisance lockouts, and moisture damage inside the furnace cabinet.
Unlike universal aftermarket tubing cut to approximate lengths, this authentic Goodman hose is pre-sized at 23 inches with the correct inner diameter and wall flexibility to seat on the factory drain barbs without kinking or leaking. Generic substitutes often collapse, harden, or fail to seal at the collector box, leading to slow drips and repeat service calls. Choosing OEM protects your warranty and guarantees a leak-free condensate path.
Easy (1 of 5). Most homeowners and technicians can swap this hose in under 15 minutes with basic hand tools. Power down the furnace, slide the old hose off the barb fittings, route the new 23-inch tube along the original path, secure the clamps, and run a test cycle to confirm free-flowing drainage.
Always confirm your model and part number before ordering. If you need help verifying fitment for your AMVM961005DXBA, contact our HVAC parts team.
