The Goodman 20214203 is a genuine OEM condensate drain angle fitting for the WFD195045S3BAA high-efficiency gas furnace and compatible Goodman/Amana models. This angled elbow connects sections of the condensate drainage system, redirecting acidic water between the collector box, trap, and drain hose while maintaining the proper slope inside a tight cabinet. A cracked or leaking angle fitting lets condensate escape onto the burner assembly and control board, and can allow air to bleed into the drain path and trip the pressure switch.
The OEM 20214203 matches the exact angle, barb diameter, and seal geometry of the original Goodman fitting for a drop-in, leak-free connection. Generic elbows may use the wrong bend or bore, require adapters, and are prone to slipping loose under thermal cycling. Genuine parts ensure a factory seal and preserve your warranty.
Replacement takes about 10–15 minutes. Shut off the furnace, remove the clamps or clips on each side of the old fitting, detach it, and press the new angle fully onto both hose ends. Confirm the drain maintains a downhill slope, then test for leaks and free condensate flow before returning the furnace to service.
