This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA13NR04800GAAAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to send 240V power to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your outdoor unit will simply not respond when the thermostat calls for cooling. You may hear the indoor air handler running while the outdoor unit stays completely silent, or notice the system running continuously without shutting off.
Compatibility: Designed specifically for the Payne PA13NR04800GAAAA 4-ton single-stage split-system condenser. Always verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Not sure if this part fits your system? Our HVAC parts specialists are available to confirm fitment before you buy — same-day shipping available on all in-stock orders.
