The Goodman 20201902 is a factory-original 23-inch condensate drain hose for the WGFM295090V5DAB high-efficiency modulating gas furnace. Cut and formed to a specific 23" length, it connects the collector box/trap circuit to the drain outlet along the furnace's designed routing path. The correct length matters: too long and the hose sags into a water-trapping loop, too short and it kinks — both cause pressure-switch faults and nuisance lockouts on condensing furnaces. Replace hardened, cracked, or scaled tubing to keep condensate flowing.
Our OEM Goodman hose arrives at the exact 23" factory length with the correct bend, so it seats on the barbed fittings and clears the cabinet without cutting or splicing. Generic bulk tubing must be measured and trimmed and can loop or crimp. OEM guarantees the right length and a leak-free, drop-in fit.
Rating: Easy (1/5). Cut power, remove the old hose from its fittings, push on the new 23" tube, and clip it in place. Under 10 minutes, no tools. Confirm the run drains downhill with no standing-water loops.
