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 it fails, the most common symptoms are an AC unit that won't turn on, a system that runs continuously without cycling off, or visible pitting and burning on the contact points inside the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V coil voltage | Factory-rated amperage for Carrier CH13NA03700GACBA | Direct OEM replacement, part number HN51KC024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier contactor manufactured to exact factory specifications.
