The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the stat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioner stops responding: you may hear a click with no compressor startup, notice pitted or fused contacts on inspection, or find the unit completely unresponsive to cooling calls.
