The contactor is a high-voltage relay that receives a low-voltage (24V) signal from the thermostat and closes to supply line-voltage power to the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will appear completely unresponsive or fail to cool despite the thermostat calling for cooling.
