The contactor acts as the main electrical switch that allows the thermostat's low-voltage (24V) signal to energize the compressor and condenser fan motor at high voltage. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the system will either fail to start entirely, run continuously without shutting off, or short-cycle unpredictably.
