The contactor is a high-voltage relay that physically closes the circuit to send line voltage to the compressor and\/or condenser fan motor whenever the 24V thermostat signal calls for cooling. When the contactor fails — through burned contacts, pitted surfaces, a stuck plunger, or an open coil — the system will not respond to cooling calls, leaving you with a unit that hums but won't start, or one that doesn't respond at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole configuration | 24 VAC coil voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 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 factory tolerances.
