The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the thermostat calls for cooling, the contactor closes to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an AC system won't start: symptoms include a unit that hums but won't run, fails to energize at all, or runs continuously without shutting off due to welded contacts.
