The Goodman 20214203 is a factory OEM condensate drain angle (elbow) fitting designed for the WGFD293090V5DAB gas furnace and compatible Goodman/Amana high-efficiency models. This angled fitting redirects the condensate drain line around tight cabinet corners, connecting the collector box or drain tube to the trap while maintaining the correct downhill slope for gravity drainage.
A properly angled drain path is essential on high-efficiency furnaces — the wrong bend can create a low spot that holds water, triggers the pressure switch, and shuts the unit down. This OEM angle is molded to the exact geometry Goodman engineered for these cabinets.
Generic elbows may not match the barb diameter or angle of the factory drain system, forcing awkward adapters that invite leaks. The genuine Goodman 20214203 mates directly with the OEM drain tubes and trap for a secure, drip-free seal on the first try.
Easy (1 of 5). Shut off furnace power, disconnect the existing drain sections, insert the angle fitting between them, and press each connection fully home. About 10 minutes with no tools. Confirm the completed drain line slopes continuously downward and re-prime the trap before startup.
