The contactor acts as a high-voltage relay, switching power to the compressor and condenser fan motor when the thermostat sends a 24V signal. When the contactor fails — due to pitted contacts, a burnt coil, or a stuck plunger — the system will either fail to start entirely, run continuously without shutting off, or trip the breaker repeatedly.
