The Goodman 0161F00046 Condensate Drain Trap is a genuine OEM replacement designed for the AMSS921005CNAA high-efficiency gas furnace and compatible Goodman/Amana models. This trap collects condensate produced by the secondary heat exchanger and routes it safely to the drain while blocking flue gases from escaping into the living space. A cracked, clogged, or missing trap is one of the most common causes of nuisance lockouts, water leaks, and pressure-switch faults on 90%+ AFUE furnaces.
This is a factory OEM Goodman part engineered to the exact port geometry and slope of your furnace's drain system. Generic universal traps often require adapters, may not seat squarely against the collector box, and can leak or trigger blocked-drain switches. For a leak-free, code-compliant repair, the OEM trap is the reliable choice.
Easy (1 of 5). Most homeowners can replace this trap in 15–20 minutes with basic hand tools. Power down the furnace, disconnect the drain lines, remove the old trap, prime the new trap with water, and reconnect. Always verify condensate flow before returning the unit to service.
