Prevent food freezing in your refrigerator, here are some measures you can take to prevent it

Check the temperature:

Make sure the temperature inside the refrigerator is set correctly. The recommended temperature is usually 3 to 5 degrees Celsius (37 to 41 degrees Fahrenheit) for the refrigeration compartment and -18 degrees Celsius (0 degrees Fahrenheit) for the freezer. Use a thermometer to measure the actual temperature and adjust the controls as needed.

Avoid overloading the refrigerator:

If the refrigerator is too full, the airflow can be obstructed, leading to ice formation. Make sure to leave enough space between the food items to allow for proper air circulation.

Inspect the door seals:

Ensure that the door seals are in good condition and seal properly. Worn or damaged seals can allow warm air to enter, causing ice formation. Regularly clean the seals with warm water and mild soap to keep them clean and flexible.

Avoid placing hot foods:

Do not place hot foods directly in the refrigerator as this can raise the internal temperature and lead to ice formation. Allow the foods to cool to room temperature before placing them in the refrigerator.

Check the thermostat and controls:

If the temperature inside the refrigerator is not consistently maintained, there may be an issue with the thermostat or controls. Check if they are functioning correctly and, if necessary, refer to the manufacturer's manual or contact a specialized technician.

Regularly defrost:

If ice has already formed in the freezer, it is important to regularly defrost it. Follow the manufacturer's instructions to properly carry out the defrosting process. Built-up ice can affect cooling performance and contribute to further ice formation.

Keep air ducts clean:

Ensure that the air ducts inside the refrigerator are not blocked by food or containers. Regularly clean these ducts to allow for proper airflow.

If you follow these tips and the problem persists, it would be advisable to contact the authorized service center of the manufacturer for a more detailed inspection of the refrigerator.
