The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose/tube for the AMH950703BXAG 96% AFUE condensing gas furnace. This length routes condensate from the collector box or secondary heat exchanger to the trap and drain line. Cut to the factory-correct 23" span with the proper bends, it prevents the kinks and low spots that hold water and cause draft pressure-switch faults.
Trimming generic hose to length risks a poor fit and leaks at the fittings. This OEM tube arrives at the exact 23" specification with molded ends that seat cleanly on the original ports, and its condensate-rated material outlasts standard vinyl tubing.
Easy. Around 10–15 minutes with no special tools. Cut power, release the clamps or friction fittings, remove the old tube, and install the new 23" tube along the same path. Check for a steady downward slope with no trapped water before returning the furnace to service.
