If you check on the following video, you will see something strange. https://youtu.be/Gq976-zFGf0 The panel’s led is blinking. If I open the main door of the cabin, or of the small for the freeze, the panel seems to work. Sometimes the motor of the refrigerator sounds to work.
When I close the door (main or the second), the problem returns. Any suggestions, please?
I did fix the problem. I called on the representatives in Athens (Greece) and they told me that they don’t have a new board. Also, on the central service in Italy, they don’t have this board anymore. But a technician advised me to replace the capacitors. Finally, yes! The problem was on the board. I replace three capacitors with new… any now my fridge works fine. The difficult was to uninstall the board from the fridge without breaking something. But now everything is ok.
