The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube built for the AMVC950905CXAA variable-speed gas furnace and related Goodman/Amana high-efficiency models. Its precise length carries corrosive condensate from the collector box and inducer assembly to the drain trap and out of the cabinet.
Over years of exposure to acidic condensate, drain tubes harden, crack, or clog with biofilm and scale. The result is water pooling at the furnace base, a tripped pressure switch, or an intermittent no-heat condition. This OEM replacement restores clean drainage and eliminates those failure modes.
A cut-to-length generic hose can leave you short or force a strained routing that kinks and leaks. This factory 23-inch tube arrives pre-sized to the exact factory run, guaranteeing a clean, leak-free installation.
Easy (1/5) — A quick sub-15-minute repair. Cut power, detach the old hose from both ends, inspect and flush the trap, then connect the new tube. No special tools required.
