The Goodman 20171701 Condensate Drain Trap is the genuine OEM trap assembly for the AMEH960805CXAA high-efficiency (90%+ AFUE) gas furnace. On a condensing furnace, the drain trap performs two critical jobs: it channels acidic condensate away from the secondary heat exchanger and inducer, and it maintains a water seal that prevents flue gases and pressure loss from escaping through the drain line.
A cracked, clogged, or wrong-fit trap is one of the most common causes of pressure-switch faults, water pooling in the burner box, and intermittent shutdowns. This factory part arrives with the correct port configuration and barb sizes so it drops straight onto your furnace without adapters.
OEM vs. Generic: The OEM 20171701 matches the exact port layout and internal geometry of your furnace, preserving the proper water seal and pressure reference. Generic traps frequently have mismatched barbs or wrong trap depth, leading to leaks, gurgling, and pressure-switch trouble codes that are frustrating to diagnose.
Install difficulty: Moderate (2/5). Shut off power and gas, disconnect the drain hoses, remove the old trap, prime the new trap with clean water to establish the seal, and reconnect all ports. Plan on 15–20 minutes; clearing the lines while you are in there is recommended.
