The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the call for cooling comes in, the contactor closes its contacts to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an air conditioning system that powers on but won't cool, or one that simply refuses to start. Symptoms include chattering or buzzing at the contactor, pitted or burned contacts, or a unit that runs constantly without cycling off.
