The contactor acts as the primary switching device that closes the high-voltage circuit to the compressor and condenser fan motor when the thermostat calls for cooling. A failed contactor is one of the most common reasons an air conditioning system won't turn on — symptoms include a unit that hums but won't start, burned or pitted contact points, or a compressor that fails to energize despite the thermostat calling for cooling.
