A:Answer Hi 0770,
We appreciate your question about the feature of switching the lights off of this Samsung refrigerator model.
The only way to turn off the lights of this refrigerator model is to turn on its Sabbath mode. In Sabbath mode, the buttons, display, and internal
lights do not function. The refrigerator and freezer; however, continue to cool.
Please refer to page 36 of the user manual of this model I have shared below to activate or deactivate Sabbath mode.
