The Goodman 0161F00046 is a genuine OEM condensate drain trap for the VMSS960804CNAA 96% AFUE high-efficiency gas furnace. In condensing furnaces, acidic condensate must drain freely while the trap maintains a water seal that keeps the pressure switch reading correctly. Over time, traps crack, clog with debris, or grow biofilm — leading to water leaks, overflow shutdowns, and pressure-switch lockouts. A fresh OEM trap restores proper drainage and reliable operation.
The OEM trap matches the furnace's exact port spacing, inlet/outlet diameters, and internal geometry, so it seats without adapters and maintains the correct water column for the pressure switch. Generic traps frequently require rework and can throw off draft-proving. OEM is the clean, correct fit.
Moderate (2/5) — Disconnect condensate hoses, remove the old trap, flush the lines, and install the new trap with fresh clamps. Prime with water before restarting. Roughly 20–30 minutes.
