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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier CH14NB03600GABAA | Replaces OEM part number HN51KC024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier contactor built to exact factory tolerances.
