New is not equal better

After 25 years I have decided to share my faithful Siemens refrigerator to a contemporary model of energy efficiency class A +++. Due to my good experience with Siemens, I have decided for the model KI24LA75.
Unfortunately you have to take in the new model also into account that the area is almost 15 liters less than in the old device, but I knew that before.
The first surprise came but then when I took cakes from the freezer. These were strangely soft for a frozen product.
When measuring the temperature I arrived at 4 ° C + in the freezer. My first suspicion that the machine was broken, has not unfortunately been confirmed. After a few phone calls and many experiments we came up with the solution.

The thermostat of the refrigerator is in the right wall in the second compartment from below, mounted in the form of a small box. Once it is conceded the refrigerator and touch any of these products this box, all the control starts skidding. With us a liter of milk touched this place. This fluttered before the thermostat, the fridge is cold enough because the milk of course takes a lot longer to warm up than the surrounding air. However, other products delay the cooling significantly, once they touch the wall at this point.
Even without the products touch the thermostat, the temperature varies in the freezer between -25 ° C and -4 ° C. From Siemens I am now very disappointed. Also in this company is now well-cheap, cheap, and again cheap produce in the foreground. Unfortunately, the consumer pays a much inflated price for this poor quality. Was probably my last Siemens device. This quality I get at cheap manufacturers.
