The contactor acts as the primary switching device that closes the high-voltage circuit to the compressor and condenser fan motor whenever the thermostat calls for cooling. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the outdoor unit will not energize at all, or may run continuously without responding to thermostat commands.
