This OEM replacement contactor (part number HN51KC024) is the factory-specified high-voltage relay for the Payne PA13NA024000BFAA split-system air conditioner. The contactor acts as the primary switch that routes 240V power to the compressor and condenser fan motor whenever the thermostat calls for cooling. When contacts become pitted, burned, or the coil fails, the outdoor unit will not energize — leaving your system blowing warm air or failing to start entirely. A chattering or buzzing outdoor unit is another telltale sign of a failing contactor.
Compatibility: Engineered specifically for the Payne PA13NA024000BFAA 2-ton single-stage split-system air conditioner. Always confirm the OEM part number HN51KC024 against your unit's data plate or existing contactor label before ordering. Our HVAC parts specialists are available to verify fitment — order with confidence and get your system back online fast.
