What is an F2 fault code ? It has just appeared on my KFN 8462 S Fridge section ?

The error code you are experiencing on your Miele KFN 12823 SD1 with four beeps and flashing of the super freeze LED, along with the 9 and 5 LEDs on the fridge temperature block, is indicating a problem with the fridge evaporator sensor. This sensor is responsible for monitoring the temperature inside the fridge compartment and is located in the fridge section.
According to the service manual, the evaporator sensor for your model is located inside the fridge compartment, behind the light unit and it can be accessed by removing the light cover. The sensor is connected to the main control board via a cable.
It's important to note that the location of the sensor can vary depending on the specific model. In your case, since the sensor seems not to be behind the light unit, it could be that it is foamed-in.
If you want to replace the sensor, you will need to carefully remove the foam insulation in order to access the sensor. This can be a delicate process and it's important to be careful not to damage the insulation, which can affect the cooling efficiency of the fridge.
It's recommended to have a professional technician to help you with the replacement, as it might involve handling with refrigerant and electrical connections.
It's also important to make sure that you have the correct replacement sensor for your model and to follow the instructions in the service manual to ensure a proper installation.

All too often it IS the fan, but not always the way you think. the impeller on the fan is simple plastic an clips on the motor shaft. and can come off very easily. Since there are not two compressors in many refrigerator/freezer combos due to both production and operation costs, the refrigerator "borrows" some of the cold from the freezer so the fan on the freezer side not operating properly will allow the coils to ice up internally, on those that only have the fan on the refrigerator side this is multiplied by the galley way icing up, blocking the cold air from reaching the refrigerator side

Faulty fan I think.

Read your manual. F2 is a fault code telling you a sensor is out of order.
