The Goodman 20201901 is a genuine OEM condensate drain hose tube engineered for the AMH950453BXAE gas furnace and compatible Goodman/Amana high-efficiency models. It routes acidic condensate away from the heat exchanger and inducer assembly to the drain trap, protecting internal components from corrosion and water damage. A cracked, brittle, or clogged drain hose is one of the most common causes of nuisance pressure-switch lockouts and water pooling inside the burner compartment.
This is the factory OEM Goodman part, molded to the exact bend radius and fitting diameter of the original. Generic aftermarket hoses often use thinner walls and universal barbs that kink, leak at the collar, or fail to seat on the drain trap — leading to repeat service calls. Choosing OEM guarantees a drip-tight seal and full compatibility with your furnace's condensate management system.
Easy (1/5) — Typically a 5–10 minute swap. Power down the furnace, slide the old hose off the barbed fittings, and press the new one into place. No special tools required. Inspect the drain trap and clear any blockage while you have access.
