The contactor acts as the primary electrical switch that sends line voltage to the compressor and condenser fan motor when the thermostat calls for cooling. When the contactor fails — due to pitted contacts, a burnt coil, or contact welding — the unit will either fail to start entirely, short-cycle unexpectedly, or run continuously without responding to thermostat signals.
