1. Low temperature setting: If the temperature of the freezer is set too low, the water in the freezer will freeze.

2. Poor sealing of the freezer door: If the freezer door is poorly sealed, it will cause outside air to enter the freezer, which will freeze the moisture in the freezer.

3. The humidity in the freezer is too high: If the humidity in the freezer is too high, the water in the freezer will freeze.

Solution:

1. Adjust the temperature: raise the temperature of the freezer to avoid freezing due to low temperature.

2. Replace the sealing strip: If the freezer door is poorly sealed, you can replace the sealing strip to ensure that the door is well sealed.

3. Reduce humidity: You can put some desiccant in the freezer to reduce humidity and avoid freezing.
