The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — the system will appear to receive a call for cooling but the compressor and fan will never energize.
