The Goodman 20171701 Condensate Drain Trap is a genuine OEM assembly designed for the AMH950704CXAA high-efficiency gas furnace and compatible Goodman/Amana models. In a 95% AFUE furnace, combustion produces acidic condensate that must be safely captured and drained. This trap maintains the water seal that lets condensate flow out while blocking flue gases from escaping into the cabinet.
This factory-original trap is molded to fit the furnace's exact port geometry and float/pressure passages. Universal or generic traps often require adapters, leak at mismatched fittings, or disrupt the pressure-switch reference, triggering ignition lockouts. The OEM part drops in cleanly and preserves the furnace's designed drainage path.
Moderate — replacement takes 20–30 minutes and involves disconnecting drain lines and pressure-switch tubing. Shut off power and label each hose before removal. Flush the trap and inspect for algae or scale buildup; clogged condensate traps are a leading cause of pressure-switch faults and short cycling. Prime the new trap with water before restarting so the seal is established immediately.
