Re: Miele KFN12924SD warm fridge
As Tony has said you have to remove the PCB at the bottom right hand corner to connect the sensor on your model.
Not easy if you are not an engineer.
The fitting of the sensor new cover is not difficult if you follow the instructions.
If you do decide to fit the sensor yourself then I would advise you to remove the PCB carefully and also take photos as you go in case you pull any leads off so you will know where to re connect them.
If you have never fitted one it can be difficult to refit the clear plastic cover to protect the connections from water or damp.
