I have the same problem, and on page 3, bottom right of the instruction manual the model no reads 000000000, so possibly your model no is 00. Also as a quick fix, remove all contents from fridge and freezer, keep doors open for 2 days, then close doors and restart as normal if it was the first time on. Believe me it works as I have to do this occasionaly with mine. This was an engineer who advised this as the pipework in the freezer freezes up and does not allow the cold air to keep your fridge cold.So by defrosting if you like of these pipes it resets the workings,
