The contactor is the high-voltage switching relay that closes when your thermostat sends a 24V call for cooling, energizing the compressor and\/or condenser fan motor. When the contactor fails — through burned contacts, a welded coil, or a worn armature — the system will either fail to start, drop out unexpectedly mid-cycle, or run continuously without responding to thermostat commands.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole | 24V AC Coil (50\/60Hz) | 25A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | OEM Part Number: HN51KB024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM contactor, manufactured to exact factory tolerances.
