The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube for the Amana/Goodman AMVC950453BXAB high-efficiency condensing furnace. It carries acidic condensate from the collector box to the drain trap along the furnace's designed routing, helping prevent overflow, corrosion, and moisture-related control failures.
Cutting generic tubing to length seems simple, but the wrong inside diameter or wall stiffness leads to kinks and slow drainage that trip the pressure switch. This OEM Goodman 20201902 arrives pre-cut to the exact 23-inch factory length with the correct bore, so it seats on the barbed fittings without leaks and maintains proper drainage slope.
Easy (1/5) — Push-on slip fit secured with a hose clamp; no cutting or special tools needed. A typical replacement takes 5–10 minutes. Disconnect power and gas before servicing.
