York 331-02957-000 Control Board Kit

The York 331-02957-000 Control Board Kit is a critical OEM replacement component designed specifically for managing the defrost cycles and sequence of operations in York heat pump systems. As a veteran technician, you know that timing and accuracy are paramount when preventing coil freeze-ups; this defrost control board utilizes advanced sensors and logic to monitor frost accumulation on the evaporator coils and initiate a reversal of the refrigeration cycle at precisely the right threshold. This HVAC control board kit is the direct replacement for legacy part number 331-09178-000, engineered to integrate seamlessly into existing wiring harnesses and chassis mounts.

Specifically calibrated for high-performance units like the HC5B(024-060)F1 and HC8B(024-060)F1 series, the S1-331-02957-000 ensures synchronized control of the compressor, fan motors, and reversing valve. By maintaining strict voltage tolerances and relay response times, this York replacement board prevents unnecessary system strain and maximizes heat transfer efficiency during extreme low-ambient conditions. When you are on a service call for a locked-out unit or erratic defrost behavior, this OEM kit provides the specific fit and reliability needed to restore factory-spec operation without the troubleshooting headaches of universal alternatives.

• Precise Defrost Management: Uses advanced algorithms to detect frost buildup, preventing coil icing and ensuring continuous heat pump performance.
• OEM Compatibility: Specifically engineered as a direct drop-in replacement for 331-09178-000, ensuring pin-for-pin terminal alignment.
• System Protection: Integrated safety features safeguard the compressor and fan motors against short-cycling and voltage fluctuations during the defrost transition.
• Optimized Efficiency: Reduces energy waste by terminating the defrost cycle exactly when the coils are clear, minimizing auxiliary heat run time.

• How do I confirm if this board replaces my current one? This kit is the official superseding part for the 331-09178-000 and s1-331-02957-000. Always verify the model number of your outdoor unit, such as HC5B or HC8B, before installation.
• What are the signs of a failing defrost control board? Common symptoms include the outdoor coil becoming a solid block of ice, the unit getting stuck in defrost mode, or the fan not restarting after a cycle.
• Does this board require programming? As a genuine York OEM kit, it comes pre-configured with the logic profiles required for compatible 2-ton through 5-ton heat pump models.
