Beko CSA22002 The refrigerator does not turn off all the time ..

Hello,

At the beginning, I am sorry as there was already this topic, unfortunately I could not find a similar one.

Starting off, my refrigerator has not turned off for some time .. It wants to freeze all the time. I think the freezer is okay. Only the tube behind the rear middle drawer is frozen and very frosted (there is ice on it and the set level is on the thermostat 2). Thermostat replaced with a new one. The refrigerator has water droplets on the back wall.
Unfortunately you have to forgive me, I'm green on this topic. Do you have any ideas what it might be? What's wrong with her ? And how much can the repair cost?

Thanks so much for all the info.

Greetings.

There were many similar topics.
If the refrigerator works all the time without any visible effect, the symptom is that there are only water drops on the back wall of the refrigerator and they should be frozen and the surface should be covered with frost, you simply have a loss of refrigerant due to a leak in the system.
You can't do anything yourself here.
The service technician could refill the refrigerant, but if there is a leak, the problem will return in some time.
You need to remove the leak and this may not be feasible in practice and you need to look around the aisle of the refrigerator.
