The Goodman 20214203 is a genuine OEM condensate drain angle (elbow) fitting for the GCH91155DXAA high-efficiency gas furnace and compatible Goodman/Amana equipment. This molded angle redirects condensate flow between the collector box, trap, and drain hose at the precise geometry the furnace cabinet requires. A cracked, brittle, or leaking drain angle is a common source of water under the furnace and can lead to pressure-switch faults if the condensate path is disrupted.
Drain angles must match the furnace's exact connection size and bend to seal properly. The OEM 20214203 seats leak-free against the factory hoses and trap, while generic fittings frequently mismatch the port diameter and weep condensate onto the base pan and controls. For a leak-critical joint, the OEM part is the reliable choice.
Very Easy (1/5). Pull the old angle from its slip connections, press the replacement fully into place, and re-secure hoses or clamps. Power down the furnace before servicing, then run the unit and verify the joint is leak-free with condensate flowing freely.
