The Goodman 20201901 is a genuine OEM condensate drain hose for the WGFM195090S4CAD gas furnace and compatible Goodman/Amana high-efficiency models. It carries condensate between the collector box, drain trap, and cabinet drain outlet along a factory-defined path, molded to resist the kinks and low spots that cause standing water and pressure-switch faults.
This OEM hose matches the original barb sizing and pre-formed geometry, dropping in without trimming or adapters. Generic tubing can fit loosely, leak at the connections, or sag and pool condensate. For a reliable, warranty-safe repair, we recommend the genuine OEM part.
Very Easy (1.5/5). Cut power, note the routing, remove the old hose from its fittings, seat the new hose fully on each barb, and confirm a continuous downward slope. Roughly 10–15 minutes with no special tools. Run water through to check for leaks before restarting.
