The average temperature of a fridge is 5°C. However, if the items located in the bottom of the product, such as milk, lettuce, tomatoes, etc, begin to freeze the thermostat is probably incorrectly set. Try adjusting the thermostat position between 1 and 2. Re-adjust until the desired temperature is achieved.
Important
In the interest of consumer safety, any adjustments, alterations or replacement
parts should only be made or fitted by a suitably qualified and competent person
with the machine disconnected from the mains supply.
