The Goodman 0161F00046 is a genuine OEM condensate drain trap for AMSS920803BNAA and compatible high-efficiency Goodman/Amana furnaces. On a condensing (90%+ AFUE) furnace, the trap collects acidic condensate from the secondary heat exchanger and maintains a water seal that blocks flue gases from escaping the drain line. A cracked or clogged trap causes water leaks, pressure-switch faults, and nuisance lockouts.
The OEM 0161F00046 is molded to the exact port spacing and hose-barb diameters of your furnace, so it seals without adapters or leaks. Generic traps often require modification and can bypass the pressure-switch tap, triggering false faults. OEM is the reliable, drop-in choice.
Easy–Moderate (2/5). Roughly 20–30 minutes. Cut power, place a rag or pan to catch condensate, release the hose clamps, swap the trap, and reconnect all hoses to their original ports. Flush and prime the trap with water before restart to establish the seal.
Compatible with Goodman and Amana furnaces using part 0161F00046. Verify your existing part number before ordering.
