My bosch KGU 3201 / GB 07 is working i.e. still cool/ freezing but it cannot keep to -18 on the freezer even though it is set to super cool 🙁
Temperature goes up and down if the super is turned off. Super is on now all the time but it struggles to keep below -10
The fridge seems fine keeping to +3
Can anyone give me advise as to what is wrong or sugguest a fix?
