The contactor is the primary high-voltage switching relay in your air conditioning system — when the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the high-voltage contacts that power the compressor and condenser fan motor. A failed contactor is one of the most common causes of a completely unresponsive outdoor unit: the system may hum without starting, fail to energize at all, or run continuously due to welded contacts.
