The Goodman 20201902 23-Inch Condensate Drain Hose Tube is a genuine OEM replacement for the AMS950704CXAB high-efficiency gas furnace and compatible Goodman/Amana models. Cut to a precise 23 inches, this flexible hose routes condensate between the secondary heat exchanger, drain trap, and outlet with the correct length and bend radius for the furnace cabinet. A cracked, brittle, or clogged hose causes leaks and drain backups that lead to pressure-switch faults — this exact-length replacement restores clean condensate flow.
The OEM Goodman 20201902 arrives pre-cut to the exact 23-inch length and correct diameter for this furnace, so it drops onto the factory barbs without measuring, trimming, or guesswork. Generic bulk tubing must be sized by hand and can kink or leak if the length or diameter is off. The matched OEM hose is the fastest, most reliable fix.
Very Easy (1 of 5). A 5–10 minute job: power down the furnace, slide the old hose off its barbed fittings, press the new 23-inch hose fully onto both connections, and secure any clamp. Prime the trap with water and check for leaks before returning the furnace to service.
