The Goodman 20214203 is the OEM condensate drain angle — an elbow fitting that directs condensate flow around tight cabinet corners inside the GMH950904CXAD 96% AFUE gas furnace. This molded angle connects drain hose segments and the collector box while maintaining the correct pitch for gravity drainage. A cracked or misaligned angle causes slow leaks, air locks, and pressure-switch faults, so a precise-fitting replacement is essential to a clean condensate path.
The genuine 20214203 is molded to the exact angle and barb diameter the furnace was engineered around, ensuring a tight, leak-free seal at each hose connection. Generic elbows vary in bend and fitting size, risking drips and improper drainage slope. For a small part that controls a critical water path, OEM is the smart repair.
Easy (1/5). Roughly 10 minutes. Power down the unit, loosen the clamps on both hose ends, remove the old angle, and press the new fitting into place with hoses re-seated and clamped. Confirm proper downward pitch and a clear trap before restarting.
