The contactor acts as the main electrical switch between your thermostat's 24V control signal and the high-voltage power supplied to the compressor and condenser fan motor. When the contactor fails, the most common symptom is an air conditioner that simply won't turn on — the thermostat calls for cooling, the control board responds, but no power reaches the load side. Pitted, burned, or welded contact points are the typical cause, often visible on inspection.
