This is the factory-specified OEM replacement contactor (part number HN51KC024) for the Payne PA13NR03000GABAA split-system air conditioner. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from the thermostat and closes the circuit to send 240V power to the compressor and condenser fan motor. When the contactor fails — whether from pitted contacts, a stuck plunger, or a burned-out coil — the outdoor unit will not energize, leaving you with warm air or no cooling at all.
Compatibility: Designed as a direct OEM replacement for the Payne PA13NR03000GABAA single-stage split-system condenser. Cross-references OEM part number HN51KC024. Verify pole count, amperage, and coil voltage on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — same-day shipping on all in-stock orders.
