The Goodman 20214203 is a genuine OEM condensate drain angle (elbow) fitting for the AMV90905DXBB 90%+ AFUE variable-speed furnace. This molded angle directs condensate around tight furnace cabinet corners while maintaining a smooth flow path from the collector box to the drain trap. A cracked or mismatched angle fitting causes leaks, air-side pressure faults, and water pooling inside the cabinet.
Generic elbows seldom match the factory barb diameter, causing slip-offs and drips. This OEM Goodman fitting provides an exact, secure connection to the matching drain hoses (20201901 / 20201902) for a reliable, leak-free assembly.
Easy (1 of 5). Press-fit replacement in under 10 minutes. Always shut off power and gas first. Consult a licensed HVAC technician if unsure.
