You are correct, the temperature control is preset, however slider may influence it.
That said, if you see a real 23 F, there is nothing you can slide it to get that cold.
The fridge has a limp mode so to speak. If it cannot sense anything, it runs none stop in a last ditch effort to keep your food cold.

Doemetic states:
Limp Mode:
This control system contains a feature where it will continue to operate the cooling system in event of a failure of a major operating component. If the control cannot read the temperature sensor and control to the preset temperature, then the control will run the cooling unit continuously at the energy source available. The refrigerator will continue to operate in this mode indefinitely or until a new sensor is installed and the system is reset.

If this is the issue, it can point to these things:
The thermistor (temp sensor) if not working correctly, Maybe loose wire.
The control board has issues.
Do you have an ohm meter? You can test the thermistor in a cup of ice water. Should get 8,000 to 10,000 ohms when the sensor is in ice water for 8 to 10 minutes. Unplug it at the control bard, connection P2 and test at the wire leeds from the sensor.
Hope this helps
John
