This OEM condensate drain trap (part number 0161F00046) is a factory-specified component for the Goodman/Amana AMVC960803BNBA 96% AFUE variable-speed modulating gas furnace. On high-efficiency condensing furnaces, the secondary heat exchanger produces acidic condensate that must drain safely away from the burner assembly. The drain trap maintains a proper water seal that prevents flue gases from escaping through the drain line while allowing condensate to flow freely, protecting both efficiency and combustion safety.
This is a genuine Goodman OEM part built to exact factory tolerances for the furnace's specific drain port geometry and trap depth. Generic or universal traps often use the wrong seal height, which can lead to condensate backup, nuisance pressure-switch lockouts, or water leaks around the cabinet. Choosing OEM protects your equipment warranty and guarantees a leak-free, direct fit.
A basic DIY replacement for most homeowners and a quick job for any HVAC technician. Power off the furnace, disconnect the drain hoses, remove the old trap, install this replacement, and reconnect the lines. Always prime the trap with water before restarting to establish the seal. No special tools required.
