The contactor is a high-voltage relay controlled by a 24V signal from the thermostat and control board — when energized, it closes the circuit to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons a packaged unit stops cooling entirely. Symptoms include the unit not turning on, buzzing or chattering noises at startup, or pitted\/burned contact points visible on inspection.
