Re: Samsung fridge freezer fridge not cooling
It has a PCB no defrost timer.
If it was iced up And not covered in a white snow all over the defrost system will be working ok.
On this model the most common problem is the drain in the freezer blocks up.
This is normaly a non return valve sticking it is fitted at the back above the compressor and is just made of rubber. Trim it off a bit with a pair of scissors just enough to stop it sticking together.
Make sure you defrost the drain so the water can run away.
