The contactor is a high-voltage switching relay that receives a 24V signal from the thermostat or control board and closes to allow line voltage to energize the compressor and condenser fan motor. When it fails — due to pitted contacts, a stuck plunger, or a burned coil — the unit will either fail to start entirely, run continuously without shutting off, or short-cycle unpredictably.
