The Goodman 0161F00046 drain trap is a genuine OEM condensate trap for the AMVM970804CNAA 97% AFUE modulating furnace. High-efficiency condensing furnaces produce acidic condensate that must drain freely while the trap maintains a water seal to block flue gases from escaping into the cabinet. A cracked or clogged trap causes water leaks, pressure-switch faults, and no-heat lockouts — making this a key maintenance and repair part.
The genuine OEM trap matches the exact port sizes, orientation, and internal geometry of the AMVM97 condensate system, so hoses seat correctly and the water seal holds. Generic traps often have mismatched port diameters that leak or restrict flow, triggering pressure-switch errors.
Moderate (2/5) — Disconnect condensate hoses, release the mounting clip, drain residual water, and fit the new trap. Priming the trap with water before startup is recommended. Roughly a 20–30 minute job.
