This is a communication fault that you are seeing it means the outside circuit board is not communicating with the display panel inside, it could be a shorted wire, control board issue etc. The only way to know is to get a volt meter and do some testing to see what the issue is. What I would do that sometimes will work is disconnect the 12 volt supply at the back of the fridge for a few mins and then hook it back up and see if the fault goes away. When you disconnect the DC supply then the panel will go blank and not show the fault. IF the fault comes back then some in depth troubleshooting will need to be done, to help you out on this see the link below page 34, this is a service manual and will step you through the checking the wires.

Hope this helps. Robert
