you probably have a defrosting issue as well, plug it out and defrost the freezer side, ideally it needs dismantling to see if there is a big build up of ice in there , if so when its defrosted plug it back in and if the temp in the fridge area comes back to normal and stays normal somebody didnt close the doors properly, if the problem comes back after a week or so the defrost elements are not doing their job. it may be down to the condenser being clogged up causing an over run
