Why the display is not responding properly in Samsung French Door Refrigerator?

Please follow the following points :
● If the refrigerator display is showing 88 88 (all eights) and is still cooling properly, unplug the refrigerator for 60 seconds and then plug it back in.
● If the display returns to normal after approximately 2 minutes service is not required. However, if the display does not return to normal service is required.
