The contactor acts as the primary switching device that allows 240V power to reach the compressor and condenser fan motor when the thermostat calls for cooling. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the system will either fail to turn on entirely, run continuously without shutting off, or trip the breaker repeatedly.
