The contactor acts as the primary switching device that connects line-voltage power to 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 unit will either fail to start entirely, run continuously without cycling off, or trip the breaker repeatedly.
