The contactor acts as the primary switching device that closes the high-voltage circuit to the compressor and condenser fan motor whenever the thermostat calls for cooling. A failed contactor is one of the most common causes of a completely unresponsive air conditioning system — symptoms include the unit not starting at all, audible buzzing or chattering at the contactor, or burnt\/pitted contact points visible on inspection.
