The contactor is a high-voltage relay controlled by the 24V thermostat circuit — when the thermostat calls for cooling or heating, the 24V coil energizes and pulls in the contacts, sending line voltage to the compressor and\/or condenser fan motor. When a contactor fails, symptoms include the system not turning on at all, a loud humming or chattering noise from the outdoor unit, welded contacts causing the system to run continuously, or visibly burned and pitted contact surfaces.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole (single-pole) | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50\/60 Hz | OEM Part # HN51KC024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part engineered to exact OEM tolerances.
