The contactor receives a 24V signal from the thermostat and closes its contacts to send line voltage to the compressor and condenser fan motor. When it fails, common symptoms include the AC unit not turning on, the compressor failing to energize, or — in the case of welded contacts — the system running non-stop even when cooling is not called for.
