The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube for the AMVC950704CXAD high-efficiency condensing gas furnace. Cut and formed to a specific 23" length, it routes acidic condensate from the furnace's collector box to the drain trap and outlet. When the original tube stiffens, cracks, or clogs, condensate backs up and can trip the pressure switch into a no-heat lockout — this direct replacement restores clean drainage.
The OEM Goodman 20201902 arrives pre-cut to the exact 23" factory length, so it drops in without trimming or guesswork. Our Generic equivalent provides the same acid-resistant tubing at a value price for techs comfortable sizing their own runs. Both are guaranteed to fit this model.
Rating: Easy (1/5). A fast 5–10 minute swap — release the clamps at both ends, pull the old hose, and press the new 23" tube onto the fittings along the original path. Verify leak-free connections and good drainage. Power down the furnace before servicing.
