The contactor acts as a high-voltage relay, receiving a 24V signal from the thermostat and closing the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — whether from pitted contacts, a burned coil, or contacts stuck open or closed — the system either won't start at all or runs continuously regardless of thermostat commands.
