The contactor acts as the primary high-voltage relay in your outdoor unit, receiving a 24V signal from the thermostat and closing to deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or welded contacts, a burned coil, or a stuck plunger — the most common symptoms are an AC or heat pump that won't turn on at all, a unit that runs continuously and won't shut off, or a loud buzzing\/chattering from the control compartment with no cooling or heating output.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole | 24 VAC Coil (50\/60 Hz) | 30A FLA | 150A LRA | 240V Line Voltage | Normally Open | 1\/4\" Quick-Connect Coil Terminals | 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, manufactured to exact OEM tolerances.
