Fan in freezer not working - Daewoo FRSU20IA Freezer

When the top half of a freezer is not working properly it is a sign that the air circulation within the freezer is not functioning. In other words, the freezer refrigerant is still working properly, but the cold air it produces isn't going anywhere: Instead, it is sinking to the bottom of the freezer (heat rises) where it does an excellent job of keeping that half of the freezer cold while missing the top section entirely.

The air circulation problem is usually caused by a fan issue. Find where your fan connects to the refrigerant system and pumps the air out into the freezer. If the fan blades are stuck or frozen, you may be able to loosen them or replace the fan. If the fan works mechanically but does not turn on the problem lies with the motor instead. In this case, you can replace the motor or call a professional it may also be fan or evaporator
