Re: Samsung f/f not cooling
On your model you have an inverter compressor.
It sounds like the compressor is faulty.
On most inverter compressors samsung give a 10year warranty
If it is covered then it should be replaced free of charge.
The other fault could be the inverter
PCB this would not be covered.
An engineer should be able to check as the inverter pcb has a neon on it that will flash a fault code.
If it is not covered by a 10 year warranty then I would get a local fridge engineer with Samsung experience.
