The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube built for the AMVC950704CXAA modulating variable-speed gas furnace and compatible Goodman & Amana condensing models. The pre-cut 23" length is matched to the factory drain routing, carrying acidic condensate from the secondary heat exchanger and collector box to the trap without kinks or slack. A cracked or clogged hose causes leaks, blocked-drain lockouts, and nuisance pressure-switch faults — this exact-length replacement restores reliable drainage.
The OEM 20201902 arrives at the exact 23" length with the correct diameter, so there is no guesswork trimming or risk of a too-short run. Generic bulk tubing can be the wrong ID, kink at bends, or degrade under condensate acidity. OEM guarantees the right fit the first time.
Easy (1/5). Cut power to the furnace, remove the old hose from both barbed fittings, seat the new 23" tube fully, and confirm the drain flows clear. No specialty tools; about 15 minutes.
Always shut off power before service. Confirm your model for fitment or contact us with questions.
