The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the thermostat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor typically results in the system not responding to a cooling call at all, intermittent compressor shutdowns, or visible pitting and burning on the contact points.
