1. Clean the door sealing strip: The sealing strip is the key to prevent airflow from entering the freezer. If the sealing strip is blocked by dust, dirt or dirt, the door will not close tightly. You can use a soft cloth and neutral detergent to clean the sealing strip to remove dirt and odor.
2. Adjust the foot pad of the refrigerator: Many foot pads of the freezer can be lifted and lowered, which is convenient for adjusting the height. If it is not balanced, it will lead to the skew or vibration of the door frame and affect the door seal. You can change the angle of the door by adjusting the foot pad to achieve the appropriate tightness.
3. Check the lock of the door: Some freezers have special locks. If they are not pushed in smoothly, the door will not close tightly. While cleaning the sealing strip, you can check the lock by the way and replace it if it is dirty or deformed.
4. Check the condenser: the condenser itself will not affect the opening and closing of the door, but it is the key component of the internal cooling of the freezer. When the condenser is blocked or fails, it will lead to the difficulty of internal air circulation, which will further affect the overall work of the freezer. You can use a vacuum cleaner to clean the dust and dirt around the condenser, thus improving work efficiency.
5. Adjust the controller: If the above problems do not exist, there may be a problem with the controller. According to experience, we can shorten or extend the refrigeration time of the refrigerator, and gradually increase or decrease the temperature to reach a suitable state. At the same time, you can also consider replacing the controller, so that electrical professionals can maintain and replace it according to relevant requirements.
