The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — you'll typically find the system completely unresponsive to cooling calls, or conversely, locked in the \"on\" position and unable to shut off.
