The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the thermostat calls for cooling, the contactor closes and delivers line voltage to the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an AC unit that won't turn on at all, a compressor that hums but doesn't start, or pitted\/burned contacts that cause erratic operation or hard starts.
