The contactor is a high-voltage relay controlled by the 24V signal from your thermostat or control board. When the thermostat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons a Carrier system hums but won't start, fails to cool entirely, or trips the breaker repeatedly.
