Condensation is usually a result of humidity entering into the fridge or when the fridge door is left open for long intervals. It may also be a result of not having enough space around your fridge or it may not be level from when the fridge was installed.

The ideal set temperature of the cabinet must be 3 degrees Celsius for fridge and -18 degrees Celsius for the freezer. 


If condensation or water drops appear on the doors, turn the Energy Saver mode off.

The heater on the door is not operating when energy saver mode is ON.

Energy Saver - Touching this button turns Energy Saver mode on and off. When you turn Energy Saver on, the Energy Saver icon lights.

Turn Energy Saver off and the icon goes off.

The Energy Saver function automatically turns on when power is supplied to the refrigerator.

If condensation or water drops appear on the doors, turn the Energy Saver mode off.

The reason why frost occurs is due to water vapor hitting cold coils and then frost forms.

Just like the steam from your breath on a cold window, the water vapor condenses and turns into water.

As the water condenses onto the coils, it freezes and thus forms a layer of frost.

Cool air in the freezer goes out and warm air enters the freezer when opening and closing door.

Warm air contains small moisture particles, these moisture particles stick to the inner wall and food with lower temperature creating frost.

It is a natural phenomenon and it is a same principle as a frosty car window during the winter.


If you wish to remove it just wipe out frost with a dry cloth.

Steps to prevent condensation occurring in your refrigerator
1 Ensure the freezer door is not obstructed by any items placed inside.
2 Check the door seals by closing the door and ensuring they are sitting flat on the cabinet surface. If any deformation (wave) or a split is found, a replacement is recommended.
3 Ensure food (especially large containers) is not stacked and is not blocking the air vents. This will result in poor cold air circulation in some areas of the storage compartment.
4 Make sure all food is covered or put in sealed containers. Moisture from foods such as vegetables and fruit can cause condensation forming inside your fridge.
5 Finally locate the temperature control in the fridge and freezer compartment and set the temperature to 3 degrees Celsius for fridge and -18 degrees Celsius for the freezer (preferred).

Please note:

- Hot items placed directly into the freezer/fridge also results in water deposition on the internal surfaces.

- Allow the items to cool down before any food items are placed in your refrigerator.
