Beko gne16122w

HI all
As you can see, this is my first post here, so please be patient with me.
I have a Beko gne16122w fridge (that gave me trouble almost from day one) which stooped now working altogether. I can hear the compressor start to work but id does not freeze nor cool at all. I would like to ask if it's possible to "bypass" the whole system by connecting the compressor (Embraco EGZ90HLC) directly to the mains and find out if its cooling or does it have a coolant control valve that blocks the coolant flow?
Does any of you people have the service manual/schematic diagram of this fridge?
Any help/ideas will be highly appreciated.
