Hi my name is ***** ***** can you kindly let me have the model number of you appliance please - likely starting with RS............
OK do you want to do this job yourself?
The problem is that the fridge fan has frozen up and is not circulating air within the fridge cavity. To carry out the repair you need to remove the back covers (behind the shelves and remove all the ice. This has to be done without breaking any of the plastic or polystyrene and is best achieved by using a steamer or wallpaper stripper. It will take about an hour to do it.
Good you now need to switch the appliance off - leave it off for about ten seconds and then back on and that will reset the temperatures in the display module and the reading should be corrected. Would you now kindly rate the information given by selecting from the star rating system at the top of the page, thank you for using JA and have a good evening.
