Carrier 308589-402 Condensate Trap

The Carrier 308589-402 Condensate Trap is a critical OEM replacement part engineered for high-efficiency drainage in residential and commercial HVAC systems. Designed specifically for condensing furnaces and rooftop units, this HVAC trap assembly prevents the backflow of combustion gases and ensures structural integrity by managing moisture removal from the primary and secondary heat exchangers. Built with durable, corrosion-resistant materials, the 308589-402 maintains a consistent water seal, which is essential for preventing air leaks that could disrupt the pressure switch operation or lead to condensate overflow and potential heat exchanger fouling.

For field technicians, this Carrier furnace part offers a compact footprint (approximately 6.3 x 3.05 x 2.95 inches) that fits within tight cabinet constraints. Proper installation of the 308589-402 trap is vital to prevent refrigerant line freezing and ensure the system meets its rated AFUE efficiency. As a genuine OEM component, it provides exact equipment compatibility, reducing the risk of nuisance trips or mechanical damage caused by improper drainage dynamics in high-demand environments.

• Optimized Drainage: Engineered to facilitate rapid moisture removal, preventing water buildup and internal component corrosion.
• System Reliability: Maintains a secure water seal to prevent flue gas leakage and ensure consistent pressure switch signals.
• Durable Construction: Fabricated from robust, heat-stabilized materials to withstand the thermal stresses of continuous furnace cycles.
• Precision Fit: Direct OEM replacement for Carrier, Bryant, and Day & Night equipment, ensuring seamless integration with existing drain lines.

• How do I know if the Carrier 308589-402 needs replacement? Look for visible cracks in the plastic housing, persistent water leakage at the trap base, or pressure switch lockout codes caused by poor drainage.
• Is this trap compatible with all Carrier condensing furnaces? While it is widely used, always verify your specific model and serial number to ensure the internal porting and mounting points align with your unit's requirements.
• Can I clean the 308589-402 instead of replacing it? While flushing with a condensate neutralizer or water can remove debris, any structural damage or hardening of the material necessitates a full replacement to maintain safety standards.
