The contactor is a high-voltage relay that receives a low-voltage (24V) signal from the thermostat and closes the circuit to supply line voltage to the compressor and condenser fan motor. When the contactor fails, you'll typically see the outdoor unit fail to energize entirely, hear a chattering or humming at the contactor, or notice pitted and burned contacts from repeated arcing — all resulting in a no-cool or no-heat condition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole | 40A FLA (Full Load Amps) | 24V 50\/60Hz Coil | 240\/277V Load Voltage | OEM Part Number: HN52TC040\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM contactor with factory-spec coil resistance and contact ratings.
