The contactor acts as the primary switching device that connects line voltage to the compressor and condenser fan motor when the thermostat calls for cooling. A failed contactor is one of the most common causes of a system that simply won't turn on — symptoms include the outdoor unit staying completely off, a chattering or buzzing noise from the contactor itself, or burned\/pitted contact points visible on inspection.
