The contactor is a high-voltage relay controlled by the 24V thermostat signal — when your thermostat calls for cooling, the contactor closes, sending line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system won't respond at all: you may hear a click with no compressor startup, notice the system is completely unresponsive, or find pitted and burned contacts upon inspection.
