Modern household appliances are equipped with various systems and functions that facilitate the operation and maintenance of them. In specialized stores you can purchase both a built-in and a free-standing refrigerator. A different class of energy consumption by the device will save. Also on sale are installations with different volume of freezers and noise level. Despite these innovations, such a question as defrosting a refrigerator always remains relevant.
Today, all produced refrigeration units have such types of defrosting, due to which the process of cleaning from ice is much easier. These include the following types of defrost:
- manual;
- drip;
- auto;
- No-frost system.

Today, refrigeration units with new defrosting systems of such brands as Bosch, Stinol, Lg, Beko, Samsung, Indesit, Zanussi and others are very popular.
Why defrost a refrigerator
The reason for the formation of ice on the walls of the freezer is the ingress of warm air. And, if you notice that freezing is happening too fast and in large quantities, then perhaps the reason is a rubber band or a violation of the thermostat.
Defrosting will eliminate odors from the refrigerator. Also, this process is necessary for the proper operation of the entire system. c With a large layer of ice coat, the device is forced to work with greater intensity. And also in case of untimely clearing of ice, the device consumes more electricity.
Timely defrosting of the refrigerator extends the life of the compressor!
Regardless of which defrosting system your appliance is equipped with, it is advisable to wash it once every six months. This should be done with a soft sponge with baking soda and warm water. This procedure will allow you to clean the refrigerator from bacteria and eliminate odor.
How often do you need to defrost a refrigerator
The frequency with which the refrigeration unit needs to be defrosted depends only on the amount of ice on the walls. Its volume depends on the temperature in the kitchen, type of defrosting and proper operation. So, if you use an old device with manual defrosting, then you will have to do it once a month. And for modern refrigerators equipped with the No frost system, one defrosting in half a year is enough.
Auto Defrost
Devices with automatic defrosting are a godsend for its owner. After all, such a refrigerator itself determines when it needs to be thawed. And such a process does not require disconnection from the network. The principle of operation of this system is as follows: under the action of heat, ice melts - and water flows through a special trough into the tank.
Drip system
Refrigerators with drip defrosting system are very popular among buyers. For such devices, an evaporator is located on the rear panel, which is responsible for cooling. There is a drain hole below the evaporator. When the compressor stops working, the ice melts - and the water enters a special container for evaporation. When the tube becomes clogged, it is necessary to clean the system from contamination.
Unlike an automatic system, a drip needs more time to defrost. But at the same time, it is more reliable, because the defrosting process occurs naturally.And in the event of a breakdown, repairing such a refrigeration appliance will be cheaper.
No frost system
The appearance of No frost refrigerators (from English - without freezing) has become a real revolution among household appliances. This type of defrosting implies the complete absence of any icing inside the equipment. The secret of such a system is that a special ventilating device provides a constant movement of air and due to this moisture is not collected, and ice does not form.
The main advantages of the know frost system are:
- does not require constant defrosting;
- evenly cools the entire area;
- constant circulation of frosty air extends the shelf life of products.
When choosing a refrigerator in the household appliance department, you can see the Frost Free marking and Full no frost. What does this mean? Let's try to find the answer. The Frost Free designation indicates that the refrigerator compartment has a drip type of defrosting, and the freezer has a know-how frost. And the Full No Frost dual-compressor models feature No Frost fans on both sides of the refrigeration unit.
With the advent of such household appliances for the kitchen, a lot of information has appeared about the harmfulness of the know frost system. In fact, this is not true. Just because of air circulation, products need to be stored packed in storage containers or special bags. And the effect on human health is no more than any household electrical appliance.
Defrosting Stages
How to defrost a refrigerator? If you still have an old refrigeration unit at home, then the defrosting process is carried out in several stages:
- Set the temperature sensor to 0 degrees.
Setting the sensor to zero degrees before defrosting
- Open the refrigerator door fully.
- Disconnect the appliance from electrical power.
- Empty the refrigerator completely from food.
- Remove all available shelves and containers.
- If the refrigerator does not have a reservoir for collecting water, then take care of a container for melt ice.
- Leave the refrigerator compartment for 5-12 hours.
- After the ice has completely melted, wash the refrigerator with warm water and liquid detergent.
- After drying completely, turn on the power supply.
If you have a two-compressor refrigerator in the kitchen, then you can defrost it both at the same time two chambers, or alternately. First turn off the refrigerator and defrost, and only then defrost the freezer.
Quick Defrost Tips
In the case when it is necessary to speed up the process of defrosting a refrigeration unit, you can use some simple tricks.
- In the freezer with an ice coat, you can put a hot water bottle.
- Place a pot or bowl of boiling water on a board or any other stand. After it has cooled completely, pour water and pour hot.
- At a sufficient distance, you can install a heat fan. The main thing is to ensure that the device does not come into contact with water.
- You can use a spray gun - spray hot water on the walls with ice.
Spraying the refrigerator with a spray gun
In order to break off the ice coat from the walls, you can not use a knife or scissors. These sharp objects can scratch the surface or damage the tube through which the freon enters.
Can I defrost a refrigerator with a hairdryer?
Is it possible to speed up the defrosting of the refrigerator using a hairdryer? You can, if you do this very carefully. To do this, keep the hair dryer at a distance no closer than 30 cm from the freezer. And be sure to ensure that the appliance does not come into contact with water. Otherwise, the flow of hot air can deform the sealing gum, and this will facilitate the passage of warm air inside during operation.
