The contactor is a high-voltage relay controlled by your 24V thermostat signal — 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 an AC system hums but won't start, trips a breaker, or simply won't respond to a cooling call.
