The Goodman 20214203 is a genuine OEM condensate drain angle fitting designed for the AMV90453BXAB high-efficiency gas furnace. This molded elbow directs condensate from the collector box or drain pan into the drain line at the correct angle, keeping the condensate path sealed and properly pitched so water never backs up into the inducer or trips the pressure switch.
The OEM 20214203 matches the exact port diameter and angle of the AMV90453BXAB drain system for a leak-free press fit. Generic elbows may not seal at the collector-box connection and can create low spots that hold water. OEM ensures proper drainage and protects your warranty.
Easy — 10–15 minutes. Cut power, detach the old angle, seat the new fitting on the drain port, reconnect the hose, and check for free-flowing condensate.
