Miele KFN12923SD – Fridge Sensor – Which one…

Hi guys,
So looks like my fridge sensor is gone.. Its either too warm or too cold in the freezer, Followed all the guides for checks and it’s still pointing towards the sensor. Not much in way of technical help for the Miele..
Anyone know what the expected working range of the sensor is before going faulty ?
There are a few different sensors online for this and not sure what one is correct one.. Not sure of the difference between the Evaporator temp sensor 7323302 and another one mention s 3100mm 4.7k ohm and the ones on whitegoods for sale where
All the ones on line are repair kits that you need to splice, no direct replacement with the pre made plug.. And no mention of the resistance range for this model..

Any help would be appreciated..

Fridge Details are.
