The Goodman 20171701 Condensate Drain Trap is a genuine OEM assembly for the GMH950704CXAC 96% AFUE condensing gas furnace. High-efficiency furnaces produce acidic condensate during combustion, and this trap safely drains that moisture while maintaining the water seal that prevents flue gases from escaping and keeps the pressure switch reading correctly.
The trap's internal geometry sets the water-seal height that both drains condensate and blocks flue gas — get it wrong and you risk pressure-switch faults, water backup, or exhaust leakage. Genuine OEM traps match factory port sizing and orientation for a clean, leak-free fit. Generic universal traps often require adapters and can leak or clog.
Moderate (3/5). Requires disconnecting condensate lines and hoses; shut off power and gas, and have towels ready for residual water. Prime the trap with water and verify free drainage before returning the furnace to service. Consult a licensed HVAC technician if unsure.
