Samsung SR-S2029GRS refrigerator doesn't cool as it should (Temperature from data logger provided) fixit

Hi,

Fridge/Freezer/Temperatures album
I am having issues with this side-by-side fridge-freezer (SR-S2029GRS). It is not cooling the way it should be - at certain times, the freezer reaches temperatures way higher than it should (see pics above).

I used an temperature data logger to record its temperatures, and it seems that it is repeating the same cycle.
Any ideas what is wrong with my fridge?

Thanks in advance.
