The Goodman 20201901 is a genuine OEM condensate drain hose tube engineered for the Amana/Goodman AMH950904CXAC and compatible 95%-efficiency gas furnaces. This molded tube carries acidic condensate through the drain circuit — connecting the collector box, drain trap, and outlet. As factory hoses age they harden, crack, or plug with sediment, causing leaks, standing water in the trap, and nuisance pressure-switch shutdowns. Fresh hoses keep the condensate system flowing and the furnace running without fault codes.
The OEM hose matches the exact factory length, diameter, and bends for a precise drop-in fit. The generic equivalent is a compatible tube at a lower price for repairs where you can trim to length. Both are rated for acidic condensate and furnace operating temperatures.
Easy (1/5). Typically 5–10 minutes: shut off furnace power, pull the old hose from its barbed connections, and push on the replacement. Verify secure, leak-free fittings and confirm clear drainage on the first heating cycle.
