Beko fridge freezer CDA543FS the back section of the fridge compartment covers with ice, I have switched it off for 48 hrs and retried it but still freezes. Replaced the thermostat complete with control switch but still freezes. Contacted beko in case it was one of the affected models, serial number starts with a 7 just outside the recall range. Help would be much appreciated.
