OEM Goodman 23 in. Condensate Drain Hose Tube for AMH951155DXAF — 20201902

The genuine Goodman 20201902 is the 23-inch condensate drain hose tube engineered for the AMH951155DXAF high-efficiency gas furnace. This longer run carries acidic condensate from the collector box and pressure-switch assembly to the drain trap. Because it is cut and formed to the factory 23-inch length, it routes cleanly inside the cabinet without sagging loops that hold water or over-tight bends that restrict flow.

• Part number: 20201902
• Length: 23 inches
• Type: Condensate drain hose / tube
• Equipment: Gas furnace (condensing / high-efficiency)
• Fits model: AMH951155DXAF and compatible Goodman/Amana furnaces
• Material: Chemical-resistant polymer for acidic condensate

OEM vs. Generic: You can trim generic tubing to length, but matching the exact inside diameter and wall flexibility of the original is guesswork. An undersized or overly stiff generic hose can leak at the barbs or trap condensate that back-pressures the drain and nuisance-trips the pressure switch. The OEM 20201902 arrives at the correct 23-inch length with the right bore, so it drops in and drains as designed.

Install difficulty: Easy (1/5). Turn off furnace power, remove the old hose from both fittings, and press the new 20201902 fully onto each barb. Reattach any clamp and confirm the run slopes continuously toward the drain. Run a heat cycle and check for leaks before buttoning up.

This is the exact OEM Goodman replacement — the right length, the right material, the right fit for your AMH951155DXAF.
