The Goodman 20201902 is the OEM 23-inch condensate drain hose tube built for the WGFM195070S4CAC high-efficiency gas furnace and related Goodman/Amana condensing models. Its precise 23" length spans the collector box or trap to the drain outlet without splicing, keeping condensate flowing freely and protecting the inducer and pressure switch from moisture-related faults.
This genuine Goodman hose arrives pre-cut to the exact 23-inch factory length with the correct inner diameter. Generic tubing must be measured, trimmed, and adapted, and cheaper materials can harden or crack under acidic condensate. The OEM part guarantees a leak-free, warranty-safe fit the first time.
Easy (1/5). Shut off power, release the clamps on the worn hose, remove it, and install the new 23-inch tube along the same routing. About 10 minutes with pliers or a nut driver. Confirm a continuous downhill slope so condensate drains by gravity.
