The Goodman 20214203 Condensate Drain Angle is a genuine OEM component engineered for the GKS90905DXAD 90%+ AFUE gas furnace and compatible GKS90 series models. During high-efficiency operation, combustion produces acidic condensate that must be routed cleanly out of the furnace cabinet. This drain angle directs that flow away from the heat exchanger and inducer, preventing pooling, corrosion, and nuisance lockouts.
Choosing this genuine OEM Goodman drain angle guarantees an exact dimensional match to the factory drain path, so the assembly seats properly and seals without leaks. Generic or universal drain fittings often require trimming, adapters, or extra sealant and can shift condensate flow enough to trigger pressure-switch faults. For a condensing furnace, a precise, watertight fit is essential to reliable operation.
Easy (1/5). This is a simple drain-path component. Cut power at the disconnect, disconnect the condensate line, swap the angle, and reconnect. Most homeowners with basic tools can complete the job in minutes; if you are unsure of your furnace's drain routing, consult a licensed HVAC technician.
