The Goodman 20171701 is a genuine OEM condensate drain trap for the Amana/Goodman AMH950704CXAD high-efficiency condensing gas furnace. In 95%+ AFUE furnaces, the secondary heat exchanger produces acidic condensate that must drain safely. This trap maintains a proper water seal, blocks flue gases from escaping through the drain, and channels condensate to the drain line. A cracked or clogged trap causes water leaks, pressure-switch faults, and nuisance lockouts.
The OEM 20171701 matches the exact port sizes and float configuration of this furnace's drainage system. Generic traps often require adapters and can leak or trip the pressure switch. For a leak-free condensate seal, OEM is the reliable choice.
Moderate (3/5). Involves disconnecting and reseating drain hoses and pressure-switch tubing; verify all connections are tight and the trap is primed with water before restart. Shut off power first. Professional installation recommended.
