1. Insufficient temperature: the freezing room of the refrigerator needs to be kept at a low temperature of about-18℃. If the temperature is not enough, the food will not freeze. At this time, you can check the temperature setting of the refrigerator and adjust it to the correct temperature.
2. Poor sealing of the freezer door: If the freezer door is poorly sealed, it will lead to the leakage of cold air, which will lead to an increase in temperature, thus affecting the freezing effect. You can check whether the door sealing strip is intact and loose, and replace it in time if there is any problem.
3. Circuit or electronic equipment failure: If the refrigerator is equipped with electronic equipment such as electronic control panel or temperature sensor, there may be a failure that leads to improper temperature control, thus affecting the freezing effect. It is necessary to find out the cause of the failure and replace the damaged parts in time.
4. Poor air circulation: Poor air circulation in the freezing room will cause uneven distribution of cold air in the whole space, thus affecting the freezing effect. You can check whether the vent is blocked and whether there are other objects around that affect air circulation.
5. Clogged condenser: Clogged condenser can also cause the freezer to freeze. Condenser blockage is usually caused by dust or dirt accumulation caused by long-term use, so it is necessary to clean the condenser in time and keep it clean.
