The Goodman 0161F00046 is the OEM condensate drain trap for the Amana AMES920803BNAA high-efficiency (92% AFUE) gas furnace. In a condensing furnace, the secondary heat exchanger produces acidic condensate that must drain away while the trap maintains a water seal so the induced-draft blower can't pull air through the drain line. A cracked, clogged, or leaking trap causes water on the furnace floor, pressure-switch faults, and ignition lockouts — one of the most common high-efficiency furnace complaints.
The genuine OEM 0161F00046 matches the port sizes, orientation, and seal height the furnace was designed for, so it drains correctly and keeps the pressure switch happy. Universal traps frequently need adapters and can alter the water-column seal, triggering nuisance pressure-switch trips. OEM is the reliable fix; a lower-cost generic equivalent is offered as an alternative.
Moderate — some plumbing (30–45 min). Power down the furnace, place a towel or pan for spillage, disconnect the drain and vent tubing, and remove the old trap. Install the new trap in the same orientation, prime it with water to establish the seal, reconnect all hoses snugly, and verify free drainage plus a proper pressure-switch reading before returning the unit to service.
