The Goodman 20214203 Condensate Drain Angle is a genuine OEM component engineered for the WGFM195090S4CAD 95% AFUE modulating gas furnace and other compatible Goodman/Amana high-efficiency models. On condensing furnaces, the drain angle routes acidic condensate away from the secondary heat exchanger and into the drain assembly. A cracked, warped, or leaking drain angle can cause water pooling, nuisance pressure-switch lockouts, and corrosion inside the burner compartment — so replacing it with the correct factory part keeps the furnace draining cleanly and running safely.
OEM vs. Generic: This is the genuine Goodman OEM part, molded to the exact port geometry and drain angle of your furnace's collector box. Universal or generic drain fittings often require adapters, can seat improperly, and risk slow leaks that void your equipment warranty. The OEM 20214203 drops in without modification and maintains factory drainage performance.
Install difficulty: Easy (DIY-friendly). Typical replacement takes 15–20 minutes with basic hand tools. Always shut off power and gas before servicing, verify the tubing seats fully, and check for leaks by running a condensate test after reassembly. If you are unsure, consult a licensed HVAC technician.
