The Goodman 0161F00046 Condensate Drain Trap is a genuine OEM component for the AMSS920403ANAA high-efficiency condensing gas furnace and compatible Goodman/Amana models. In a 90%+ AFUE furnace, combustion produces acidic condensate that must drain away while maintaining a water seal that blocks flue gases from escaping into the cabinet. This molded trap provides that seal. A cracked, clogged, or missing trap causes water leaks, pressure-switch faults, and ignition lockouts.
The OEM 0161F00046 is molded to the precise port spacing, hose-barb diameters, and internal trap geometry your furnace requires. Generic traps often leak at the connections or fail to hold the correct water seal, triggering pressure-switch errors. The OEM trap is the reliable choice for condensing units.
Moderate (2/5). Requires disconnecting several condensate hoses and clamps and priming the trap with water before startup. Cut power, note hose routing, swap the trap, reconnect and clamp, then fill the trap. Around 30 minutes.
