This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA13NR04800GADAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to deliver 240V power to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a worn coil, or contacts stuck open or closed — the system will either fail to start entirely, run continuously without shutting off, or trip the breaker repeatedly.
Compatibility: Engineered specifically for the Payne PA13NR04800GADAA 4-ton single-stage R-410A split-system condenser. Always confirm the coil voltage and pole configuration on your unit's data plate before ordering. Our parts specialists are available to verify fitment — your system runs right or we make it right.
