The Goodman 20171701 is a genuine OEM condensate drain trap designed for the high-efficiency Amana/Goodman AMH950453BXAB gas furnace. In a 95%+ AFUE condensing furnace, the drain trap safely channels acidic condensate away from the secondary heat exchanger while maintaining the pressure seal that keeps flue gases out of the drain line. A cracked, clogged, or aged trap can cause water leaks, pressure-switch faults, and nuisance lockouts.
The OEM trap matches the exact port geometry and internal baffle design of your furnace, preserving the correct pressure seal and drainage path. Generic traps often require adapters and can trigger pressure-switch errors if the seal height differs. Choose OEM for a leak-free, code-correct fit.
Rating: Easy (2/5). Disconnect the drain hoses, remove the mounting screws, swap the trap, and reconnect. Flush and prime the new trap with water before startup. Power off the furnace before servicing. Suitable for most DIYers.
