The contactor is the high-voltage relay that receives a low-voltage (24V) signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will appear completely unresponsive: the thermostat calls for cooling, but nothing happens. In other cases, a welded contactor causes the unit to run continuously even when cooling is not demanded.
