Please leave the fridge and freezer switched on during your entire stay and also when you leave! For the freezer compartment, the switch should show a red dot as shown in the image below (outlined in red).
Unfortunately, the light from the refrigerator is broken. However, so that you can still see something in the dark, we have installed a small lamp (green border) with batteries on the right side of the refrigerator.
If this no longer works, the batteries are probably empty and need to be charged. To do this, simply remove the lamp. It is only attached with a magnet.
To open the lamp, simply turn the black cover to the left and then remove the batteries. A charger can be found in the white cupboard under the TV, on the far left.
