The Goodman 0161F00046 Condensate Drain Trap is the genuine OEM trap for the AMSS960803BNAA 96% AFUE gas furnace and related Goodman/Amana high-efficiency models. In a condensing furnace, the secondary heat exchanger produces acidic condensate that must drain freely; this trap maintains the water seal that lets condensate exit while blocking flue gases from escaping into the cabinet. A cracked or clogged trap is a frequent cause of pressure-switch lockouts and nuisance shutdowns.
The OEM trap matches factory port sizes, elbow orientation, and internal baffle geometry so it seats to the collector box without leaks and holds the correct water column. Generic traps often mismatch port diameters or seal height, causing slow leaks and false pressure-switch faults. For a condensing furnace, OEM fit is worth it.
Easy to Moderate (2.5/5). Power down the furnace, remove the door, disconnect the inlet and outlet hoses and clamps, unseat the old trap, then install and re-clamp the new one. Prime the trap with water before restarting. Typically 20–30 minutes with basic hand tools.
