The Goodman 20171701 is a genuine OEM condensate drain trap for the GMV91155DXBA 96% AFUE furnace and compatible Goodman/Amana high-efficiency models. In a condensing furnace, the secondary heat exchanger produces acidic condensate that must drain away while the trap's water seal blocks combustion flue gases from escaping into the drain line and the home. A cracked, clogged, or missing trap triggers pressure-switch faults and lockouts.
The OEM Goodman trap matches the exact port diameters, mounting orientation, and float configuration of the GMV9 cabinet. Generic traps rarely align with the factory drain routing and can leak or fail to hold the proper seal, leading to pressure-switch nuisance trips. We recommend OEM for reliable drainage.
Moderate. Requires disconnecting drain tubing and mounting hardware, then priming the trap with water before startup. Plan for 20–30 minutes. Kill power first and inspect all hoses for cracks while you're in there.
