The contactor acts as the primary electrical switch that allows 240V power to flow to the compressor and condenser fan motor when your thermostat signals a call for cooling. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed 24V coil — the system will appear completely unresponsive or will fail to start despite the thermostat calling for cooling.
