The contactor acts as the main switching device that allows 240V power to flow to the compressor and condenser fan motor when the thermostat calls for cooling. When a contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your system will either refuse to turn on entirely, fail to shut off, or short-cycle unpredictably.
