The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM replacement for the AMH950453BXAD high-efficiency furnace. This flexible tube carries acidic condensate between the collector box, drain trap, and discharge line inside the furnace cabinet. Over time, factory hoses can crack, harden, or develop biofilm clogs that trigger pressure-switch lockouts and water leaks — making this an inexpensive but essential maintenance replacement.
The OEM hose is cut to the exact factory length and bend radius, ensuring clean routing without kinks that restrict flow. Generic tubing often requires trimming and may not resist acidic condensate as well, shortening service life. For a few dollars, OEM removes the guesswork.
Very Easy (1/5). Power off the furnace, slide the old hose off its barbed fittings (release any clamps), and press the new hose on in the same path. Reseat clamps and confirm no kinks. Under 15 minutes with basic tools.
