The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the thermostat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons a packaged unit appears completely unresponsive: you may hear a faint click with no compressor engagement, notice pitted or burned contact points, or find the system stuck in a no-cooling lockout.
