The contactor acts as a high-voltage relay controlled by a low-voltage (24V) signal from the thermostat. When the thermostat calls for cooling, the contactor closes to send 240V power to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an air conditioner that simply won't turn on — the system may hum, chatter, or show no response at all when cooling is demanded.
