AEG santo N9 fridge not working?

It is 3 years old, the freezer works but not the fridge, can't adjust the temperature. We took the back plate off but can't seem to remove the fan cover, I see three tiny tabs which look like they have to be pushed in but the thing will not budge.

New thermostat required at a guess.
