Hi
Common fault on these is grills blocked behind lower plastic grill below freezer door. Clean out all dust and fluff, then see if fridge temp lowers. If not it is usually the yellow thermister located inside freezer, remove drawers and you will find the removable panel at the back. I picked a thermister up on ebay for £6. Disconect from mains and simply plug in new one or try fully defrosting both fridge and freezer for 24 hous
