When you press the fridge or freezer temperature adjustment key, the characters in the fridge or freezer temperature display zone will flash. At this time you can adjust the temperature. After adjustment, if there is no key action in 5 seconds, the displayed value will stop flashing and return to original value to display actual temperature. In this case some users may think in mistake that the temperature cannot be set,but it is normal in fact.
Because the temperature you set is different with the actual temperature in the compartment, it needs a temperature balance process. After that it will display the setting temperature gradually.
Do not worry,it is a normal phenomenon.
