The Goodman 20214203 is a genuine OEM condensate drain angle fitting for the GMH950905CXAA high-efficiency gas furnace and compatible Goodman/Amana condensing models. This angled elbow directs condensate flow around the furnace cabinet and connects the collector box or trap to the drain hose, maintaining proper slope so condensate drains freely. A correct-fit OEM angle prevents the standing water and back-pressure that can trip the furnace's pressure switch.
Genuine OEM 20214203 fittings match the exact bend angle and barb dimensions of the factory drain assembly for a secure, leak-free seal. Generic elbows may have mismatched angles or diameters, causing drips, poor drainage, and nuisance lockouts.
Easy (DIY-friendly). Detach the connected hoses, swap the angle fitting, and reconnect. No special tools required. Shut off power and gas before servicing and confirm the condensate path maintains a continuous downward slope.
