The contactor is a high-voltage relay controlled by a low-voltage (24V) signal from the thermostat or control board. It switches line voltage to the compressor and condenser fan motor whenever a cooling call is made. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will not energize, leaving you with warm air or a completely unresponsive outdoor unit.
