The fridge setting is at 3 (of a range of 1 to 5) and hasn't been changed all summer. Once in the past, the control was accidentally turned to the highest setting and this was only discovered when liquids stored in the fridge began to freeze, but that hasn't happened since that one occasion: despite the presence of the ice, milk, fruit juice and so on are still liquid.
The fridge is the top half of a Beko fridge-freezer and the freezer is working perfectly. Should I be concerned about this? Does it indicate that something's wrong somewhere? Many thanks.
