The contactor is a high-voltage relay that connects and disconnects power to the compressor and condenser fan motor whenever the thermostat calls for cooling. When it fails — due to burned or pitted contacts, a stuck plunger, or a failed 24V coil — the system will either refuse to start entirely, run continuously without shutting off, or fail to energize the compressor while the fan runs.
