This OEM contactor (part number HN51KC024) is the factory-specified replacement for the Carrier CH14NB03600GABAA split-system condenser. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the thermostat calls for cooling, the contactor closes and delivers line voltage to both the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an air conditioner that simply won't turn on, a unit that runs constantly without cycling off, or visible pitting and burning on the contactor's contact points.
Compatibility: Designed specifically for the Carrier CH14NB03600GABAA 3-ton split-system condenser. Always verify coil voltage and pole configuration against your unit's wiring diagram and data plate before ordering. Our fitment team is available to confirm compatibility before you purchase — no guesswork required.
