The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the stat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. When the contactor fails, pitted or burned contacts cause the system to hum without starting, fail to energize at all, or run continuously without shutting off.
