Suggested solution:

First, adjust the set temperature of the refrigerator, a little higher.

Try to avoid putting steaming food directly in the refrigerator, which will increase the consumption of electricity for no reason, and the food so combined is not very good for your health.

Reduce the frequency of opening and closing refrigerator doors.

It is suggested that some foods with high moisture content should be sealed with plastic wrap and then put into the refrigerator, which can not only keep fresh more effectively, but also reduce power consumption.

Check whether the sealing strip is still working, and you can contact the refrigerator maintenance personnel to directly replace it with a new one.

6. Contact the after-sales maintenance personnel of the refrigerator to check whether the thermostat of the refrigerator is out of order. If there is a problem, you can directly replace it and try not to repair it.
