The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to energize the compressor and condenser fan motor. When a contactor fails, the most common symptoms are an AC unit that simply won't turn on, a compressor that won't engage despite the thermostat calling for cooling, or a unit that hums loudly without starting. Pitted or burned contacts are the leading cause of contactor failure in residential condensers.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V AC coil voltage | 30–40 amp rated | OEM part number HN51KC024 | Factory-matched electrical specifications for Carrier CA13NA03000GAABA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors use silver-alloy contact tips rated for the exact inrush current of your Carrier compressor.
