The Goodman 20214203 Drain Angle Fitting is a genuine OEM condensate drain elbow designed for the Goodman GCH90704CXAA high-efficiency gas furnace. This angled fitting redirects condensate flow around the furnace cabinet, connecting drain hoses and the trap at the correct angle so water drains freely instead of pooling. In condensing furnaces, a properly seated drain angle prevents trapped condensate that would otherwise trip the pressure switch and cause intermittent no-heat lockouts.
The OEM 20214203 is molded to Goodman's exact angle and port diameter, mating precisely with the factory drain hoses and trap for a leak-free seal. Generic elbows often have the wrong angle or a loose fit, causing seeping joints and water damage inside the cabinet. Because this fitting handles acidic condensate, the exact-fit OEM part is the reliable choice.
Easy (1/5). Shut off power to the furnace, disconnect the drain hoses from the old angle, and press the new 20214203 into place in the same orientation. Confirm each hose seats fully and the joints are snug. Prime the trap, run a heat cycle, and check for drips.
