The Goodman 20171701 condensate drain trap is a genuine OEM component for the AMH950703BXAG high-efficiency condensing furnace. The trap collects acidic condensate from the secondary heat exchanger and inducer, maintaining a water seal that allows condensate to drain freely while preventing flue gases from escaping through the drain line. A properly sealed trap is essential for safe, code-compliant operation.
The trap's port spacing, seal geometry, and internal baffling are specific to this furnace's drainage layout. Our OEM Goodman trap connects to the factory hoses without adapters and maintains the correct water-seal height. Generic traps often require rework and may not seal against flue-gas leakage — OEM is the reliable choice for this safety-related drainage part.
Moderate (3/5). Shut off power and gas, remove the condensate hoses and mounting screws, drain and replace the trap, then reconnect and prime it with water to establish the seal. Check for leaks and confirm proper drainage before returning the unit to service. Clean or replace the trap periodically to prevent clogging.
Condensate system service is best handled by a qualified HVAC technician.
