The contactor is a high-voltage relay that receives a 24V signal from the thermostat or control board and closes its contacts to send line voltage to the compressor and condenser fan motor. When a contactor fails — due to pitted or fused contacts, a burned coil, or a stuck plunger — the system will either refuse to start entirely or run continuously without responding to thermostat commands.
