The Goodman 20201901 is a genuine OEM condensate drain hose tube built for the AMH950453BXAA high-efficiency gas furnace and other compatible Goodman and Amana models. This pre-formed tube carries condensate from the collector box and drain trap to the discharge point, protecting the heat exchanger area from standing water and corrosion.
The OEM Goodman 20201901 matches the factory length, inner diameter, and bend radius for the AMH950453BXAA, so condensate flows freely and the drain trap primes correctly. Generic tubing can be over- or under-sized, leading to slow drainage, gurgling, or pressure-switch faults. Choose OEM for a guaranteed fit and full flow.
Easy — Detach the old hose from its barbed fittings, release any clamps, and press the replacement tube firmly onto both ends. Confirm a leak-free seal and a continuous downhill slope to the drain. Minimal tools required.
Always shut off power and gas before servicing. This is a genuine OEM Goodman/Amana replacement part.
