Are only some food such as vegetables/fruits/tofu frozen?
Food can freeze when the set temperature is lower
than the food’s optimal temperature.
Also when those easily frozen are located near the cold air outlet,
they can freeze.
How to fix
1. Avoid storing bean sprouts and tofu near the cold air outlet
as they can be freeze easily.
Place them in front of the shelf and adjust the temperature to middle or low.
2. Store vegetables/fruits in vegetables and fruit drawers.
