The contactor acts as the main electrical switch 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 — the system will hum or fail to start entirely, leaving you with no cooling even when the thermostat is calling.
