This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA13NR030000ABAA split-system air conditioner. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to power the compressor and condenser fan motor. When a contactor fails — due to pitted contacts, a burned coil, or contacts that weld shut — your system may hum and fail to start, run continuously without shutting off, or simply produce no response at all when cooling is called for.
Compatibility: Designed specifically for the Payne PA13NR030000ABAA 2.5-ton single-stage split-system air conditioner. Always verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you purchase — same-day shipping means you're back up and running fast.
