This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA12NA030000AHAA split-system air conditioner. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a stuck plunger, or a burned coil — your outdoor unit will not energize even when the thermostat calls for cooling, leaving you with warm air and a running air handler.
Compatibility: Engineered specifically for the Payne PA12NA030000AHAA split-system condenser. 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 prior to purchase — same-day shipping means you're back up and running fast.
