Carrier 308589-401 Condensate Trap

The Carrier 308589-401 Condensate Trap is a critical OEM replacement part engineered for high-efficiency condensing furnaces and AC systems. This factory authorized part is designed to manage the precise drainage path of corrosive condensate produced during the combustion and cooling process. Built from durable, chemical-resistant materials, the 308589-401 trap prevents the backup of moisture into the secondary heat exchanger or inducer housing, which is a common cause of furnace pressure switch errors and system lockouts. With its 1/4 inch and 5/8 inch inlet ports and a 5/8 inch outlet, this trap ensures a proper water seal to maintain the static pressure balance required for safe operation. For veteran techs, this is the standard solution for Carrier furnace condensate drainage issues, effectively resolving error codes 31, 32, and 42. Utilizing a genuine Carrier 308589-401 ensures an exact fit and restores the integral safety drainage required for high-performance HVACR equipment.

• OEM Compatibility: Specifically engineered to fit Carrier, Bryant, and Payne high-efficiency equipment, ensuring a seamless interface with existing drain line connections.
• System Protection: Effectively prevents water from backing up into the inducer motor and secondary heat exchanger, mitigating the risk of premature component failure and corrosion.
• Accurate Drainage: Provides the necessary U-trap configuration to maintain the water seal against positive and negative pressures within the cabinet.
• Durable Construction: Made from high-grade materials specifically tested to withstand the acidic nature of furnace condensate.

What are the signs that a 308589-401 trap needs replacement?
Technicians should look for sloshing sounds in the inducer motor, water leaking from the trap seams, or persistent pressure switch failed to close codes. If debris buildup cannot be cleared through standard flushing, a full replacement is required to restore flow.

Will this trap resolve furnace error code 42?
Yes, code 42 on many residential units indicates a condensate double trap or blockage issue. Replacing a cracked or severely fouled 308589-401 is the standard protocol for clearing this fault.

Can I use an aftermarket universal trap instead?
Using the genuine Carrier 308589-401 is highly recommended over universal kits to ensure the port sizes and internal baffle designs match the original airflow and drainage specifications of the unit.
