The contactor is a high-voltage electromechanical relay that acts as the primary power switch for your compressor and condenser. When your thermostat sends a 24V signal, the contactor coil energizes, closing the high-voltage contacts to start the system. A failed contactor is one of the most common causes of a complete no-cool or no-heat condition — symptoms include the outdoor unit failing to start, audible chattering or humming at the contactor, pitted or burned contacts, or the unit running continuously without shutting off.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole | 30A Full Load Amps (FLA) \/ 150A Locked Rotor Amps (LRA) | 24 VAC Coil Voltage | 50\/60 Hz | OEM Part Number HN51KC024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, manufactured to exact factory tolerances for the PH4ANG048000BCAA.
