In a high-efficiency furnace, the secondary heat exchanger produces acidic condensate that must drain freely while the trap maintains a water seal — preventing flue gases and combustion-air pressure from escaping through the drain line. A cracked, clogged, or missing trap triggers pressure-switch faults and furnace lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComponent: Condensate drain trap assembly\u003c\/li\u003e\n\u003cli\u003eMaterial: Molded corrosion-resistant polymer\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS90905DXAA and compatible condensing furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20171701\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eFunction: Maintains water seal, routes acidic condensate to drain\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e trap matches the exact port diameters, inlet\/outlet geometry, and mounting footprint of your furnace, so hoses seat correctly and the water seal holds. Generic traps rarely align with Goodman's multi-port design and often leak or restrict flow, leading to intermittent pressure-switch open faults that are hard to diagnose.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Plan on 20–30 minutes. Power down the furnace, place a towel to catch residual water, disconnect the drain hoses (note each connection), unclip the old trap, and fit the new one with the same hose routing. Prime the trap with clean water before restarting so the seal is established. Flushing the trap seasonally extends its life.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eDisconnect power before servicing.
