Hi all I am looking for some advice on this three door american side by side, electrolux from John Lewis. It gets too cold in fridge and the display on front says +14 and above. It seems to have a built in sensor behind evaporator wall which is not available on the spare parts list on the electrolux website. Does anyone know of a diagnostic test on the module as this seems the only part that could have failed other than the sensor? Thanks Gary
