Repair to Bosch fridge freezer KGV3104GB
This MIGHT be the same as yours!
Detach top panel above fridge door and "hinge" it down towards you attached to its connecting wires. See if the connector on the right has a thick black wire (nearest the fridge) and two brown wires. The faulty fridge temp. sensor can be shorted out by connecting the black wire to the brown wire next to it. I managed this by bridging the corresponding points on the PCB with a blob of solder. My fridge freezer works OK now on the freezer sensor. Hope this works with yours!
