Why does the refrigerator freeze and should this layer of snow be removed?

Faced with the phenomenon of refrigerators freezing after long periods of use, many people do not know the cause and whether they should remove this layer of frost from the refrigerator or not.

After a period of use, many refrigerators have a layer of spongy, white snow. This layer of snow becomes increasingly thick and hard, affecting the functionality of the refrigerator.

Snow often forms in patches on the walls of the refrigerator, even clinging to the food in the freezer. The thicker the refrigerator is frozen, the lower its ability to cool and preserve food, the storage area is narrowed and it consumes a lot of electricity.

Reasons why the refrigerator freezes

There are many reasons why refrigerators freeze, including:

• Habit of putting hot food in the refrigerator and frequently opening the refrigerator : Frequently opening the refrigerator and putting hot food in increases water vapor in the refrigerator compartment, causing the device to not focus on cooling in the right place. The amount of steam introduced into the above cabinet freezes into snow.
• The refrigerator door is open : Water vapor from outside is also the cause of frost in the refrigerator.
• Not regularly cleaning the refrigerator : If you do not clean the refrigerator regularly, food, dirt, and grease will fall out, causing the gears to become worn or stuck, and the heat transfer process will decrease sharply, thereby causing a layer of snow. thicken.
• Timer - defrost relay is broken : In most refrigerators, the timer is located right in the vegetable compartment or at the back of the refrigerator, in the electrical box next to the compressor. Its task is to switch the compressor off to defrost mode. When this important part is broken, the defrost process will pause. The burned motor coil causes ice to freeze in the refrigerator, forming layers of snow.
• Cold clams - the refrigerator's negative circuit is not clear, the electric fuse is broken, which is also the cause of the refrigerator freezing.

The formation of a thick layer of snow in the refrigerator causes many problems for users, such as:

• Narrow the usable space
• Makes noise from the fan
• Reduces cooling performance as well as the ability to preserve food
• Consumes more electricity but is not as effective.

Removing this frozen layer is essential and should be done as soon as possible.

Should we pry off the layer of snow in the refrigerator?

With the above causes and harmful effects, removing this layer of frozen snow is necessary and should be done as soon as possible to promote the inherent uses of the refrigerator, increase food preservation efficiency and reduce electricity consumption. consumption capacity.

How to remove frost in the refrigerator:

• First, you need to remove all food from the refrigerator, including items in the freezer and refrigerator.
• Open the refrigerator door all the way and place a cup of hot water inside to let the heat of the water melt the snow. A quicker way is to use a fan or dryer to melt the snow faster.
• After the snow melts, use a clean towel to wipe the entire surface of the refrigerator; The compartments can be removed and cleaned, then dried and reinstalled in the cabinet.
• Put food in the refrigerator and use normally. Watch to see if your refrigerator works more efficiently afterward.
• In case you discover that the refrigerator has signs of freezing due to the above reasons, call an electrician to replace new parts, helping the refrigerator operate normally.
• In addition, to keep the refrigerator working well and without frost, you need to note:
• Adjust the appropriate temperature: Cool compartment from 3 - 5 degrees Celsius, freezer about - 18 degrees Celsius.
• Clean and defrost the refrigerator regularly so that cold air circulates evenly throughout the inside of the refrigerator and food is better preserved.
• Maintain your refrigerator periodically every 3 - 4 months so that the cooling system operates normally.
