Can I defrost the no-frost fridge?

Do I have to defrost my LG No Frost fridge?

It is a misconception that refrigeration units equipped with an auto-defrost function do not require special maintenance. Defrost refrigerators with a No Frost system should be defrosted for the following reasons:

  • All foods contain moisture, which is released into the environment. This is particularly true for liquid foods, drinks, fruit and vegetables. Liquid particles precipitate on the walls and freeze, forming ice.
  • The fridge defrosts, but does not defrost automatically. Sometimes it is necessary to remove dirt that accumulates on the walls and shelves. This helps to prevent the growth of pathogenic microorganisms and the appearance of unpleasant odors.
  • When the compressor is turned off, condensation forms on the walls, which must be drained through the gutters. These elements can become clogged, causing liquid to accumulate in the refrigerator.

Defrosting the Bosch refrigerator

There are two options for defrosting: built-in and manual. In the first case, it is a drip system. Drip defrosting involves the formation of condensation flowing down the back of the unit, making it known as “weeping”. Despite the automatic system, for hygienic purposes, such a unit should be additionally defrosted 1-2 times a year.

To defrost by the second method, by hand, it is necessary to first disconnect the unit from the power supply. Then take out the foodstuffs stored inside. To prevent food from spoiling, you can carefully wrap it in kitchen towels or newspapers and put it away from direct sunlight.

After the Bosch refrigerator has defrosted, it should be cleaned.

You can use a solution of water with detergent and alcohol. You need about 1 capful of the product for 1 liter, add the alcohol in the ratio of 1:4. This will not only help to clean the surface, but also to disinfect it.

Next, the rooms need to be aired out. After turning it back on, you can put the food back. Depending on the amount of ice, the entire process can take from 1 to 12 hours. In the case of “No Frost” it will take less time. 1-2 hours, otherwise the process is the same.

Defrosting the Bosch double refrigerator

Defrosting the Bosch two-compartment refrigerator is carried out on the same principle, although you should pay attention to the presence of one or two compressors.

Instructions to defrost the Bosch two-chamber fridge:

  • Unplug the unit and remove food from both compartments.
  • Place a tray or container underneath the freezer where the water will drain off. Put towels on the bottom of the chamber.
  • Clean any frost off the walls of the chambers, then wash them with a solution of water and detergent according to the recipe in the previous section. Then wipe them down well and leave them to dry.

To defrost a Bosch dual-chamber refrigerator quickly, you can put closed containers with hot water inside. Do not allow sharp temperature changes, so the use of boiling water or powerful heaters is not recommended.

Breaking off pieces of ice, the use of hard sponges and agents with abrasive particles can damage the surface of the walls, this is also best avoided.

The chambers of a unit with two compressors can be defrosted all at once or separately. Therefore, the instruction for defrosting the two-chamber “Bosch” refrigerator, which has two compressors, in general, will not differ.

After the chambers have been washed and dried, you can load the food back in. It is worth defrosting a Bosch two-compartment refrigerator once every six months, depending on the degree of icing.

Defrosting the freezer compartment

In Bosch refrigerators, you can defrost the freezer compartment using the same principle. The main problem here is the ice.

You should start with the top compartment, where the ice accumulates the most. Wipe the surface with a sponge soaked in warm water. If there is too much ice, you can try using a hair dryer. Avoid too high temperatures.

When the ice is completely thawed, rinse and dry the chamber. You can do this once or twice a year.

Defrosting the Bosch built-in freezer

In order to defrost the built-in refrigerator “Bosch”, it will be enough to follow the instructions above. To prevent moisture from getting on nearby furniture, it is worth carefully watching its outflow.

Tips for defrosting LG fridges quickly

You can find tips online to help speed up defrosting:

  • Place a heating pad or a bowl of hot water in the freezer.
  • Spray the walls with heated spray water.
  • Put the heater turned on in front of it so the water does not get on it.
  • Turn on the hair dryer, direct the hot jet inside from a distance of 30 cm. Don’t blow on the rubber seal. it will deform.
  • Turn off the unit in hot weather.

Using these methods is undesirable. there is a risk of damaging the appliance. It is better to let the cooling system thaw naturally and follow the manufacturer’s recommendations.

Peculiarities of defrosting

To defrost an appliance equipped with the no-frost system, it is necessary to perform rather simple manipulations in sequence:

  • Unplug the fridge. Only after that we open its doors and unload the contents of the chambers.
  • Now take out the shelves, containers and all removable parts. Thoroughly wash them from dust and dirt, erase stains, put them out to dry.
  • First the chambers should be wiped with a dry cloth to collect not only the dirt but also the remaining condensate. Then wipe all surfaces with a cloth moistened in a soap solution. If there is an unpleasant odor or serious contamination, a baking soda solution should be used.
  • Wipe the surfaces with a clean, damp cloth and then use a dry cloth. Although a no-frost appliance is capable of drying itself out on its own, it is not worth testing its capabilities.
  • Now the appliance should stand for the recommended 24 hours with the doors open.
  • Insert the trays and shelves into the cleaned chambers and load the foods. After closing the doors tightly it is time to plug in the fridge. By the way, you should not open and close the doors immediately in the usual mode, you should wait at least half an hour for the device to work properly.

As with most conventional refrigeration units, no-frost appliances are recommended to defrost in the cooler months. Otherwise, a sharp temperature drop can provoke a breakdown. If the situation is such that manipulation must be performed in a hot day, you should at least cool the room as much as possible with the available means and plan the beginning of the procedure for the evening or night time.

Manual defrosting system in the refrigerator

Manual defrosting of the freezer compartment speaks for itself. this means that approximately once a year or so, you will need to turn off the freezer and defrost it, freeing it from freezing and ice, if any. The thawed water will then need to be collected and poured out, and the camera washed and wiped clean.

Moisture from the air and food placed in the freezer will accumulate on the walls and freeze, so frost and ice will constantly form inside the chamber. If it does not have an automatic defrost system, the unit is defrosted manually.

How to defrost a fridge with a manual defrosting system

Clean ice and snow from the refrigerator at room temperature. Unplug it, take the food out of the chambers, and place containers and cloth strips on the shelves where the melt water will accumulate. Wait for natural defrosting.

The large pieces of ice that fall off are discarded. Then wash the unit with a soapy solution. Detergents must not contain chlorine, strong alkalis or acids. After the procedure, the surface is thoroughly wiped clean.

Advice. If you have free time, leave the appliance for 2 to 3 hours until all moisture has evaporated from inaccessible areas.

After drying, the food is returned to the shelves and the unit is plugged in.

In the summertime, minor defrosting takes 2-3 hours, stronger defrosting takes 6-8 hours. In a winter or cooler environment, the process takes much longer. To avoid waiting several hours for natural defrosting, you can use accelerated procedures:

Using heating devices. hair dryers, heaters, heat guns, etc., which are set at a safe distance. The internal parts of the refrigerator are not designed for exposure to high temperatures, so this method should be used with caution. Allowable value of heating. 60 ° C. In order to speed up the process, an additional fan is installed.

Blow through with room temperature air. This reduces the defrosting time by half in summer. A fan is used to create airflow.

Plastic bottles with warm water and lids with a hole are placed in the chamber. The method is effective and fast. the unit is cleared of ice for 10-15 minutes. Do not use boiling water.

To defrost with steam, place several containers of hot water in the refrigerator and close the door. The larger the container and the higher the temperature of the liquid, the faster the process goes. To accelerate the water, periodically change to a hotter one.

Defrosting is carried out when the technique is minimally loaded with products. To preserve them in the cold, they are taken out onto a balcony or placed in a cellar. If this is not possible, or if it is warm outside, other storage methods must be used. For example, wrap the food in plastic bags, stack them side by side and cover them with a warm blanket. This way they create an insulating layer that does not let them thaw for a few hours.

If allowed to warm food to cold water temperature, bags are lowered into a container with liquid. It is desirable to have a flow-through. This is how fish, meat, and uncooked foods are kept. Also, ice is used for storage. It is poured into a container, in which the food packets are then placed.

Important! When defrosting, do not break the ice with your hands or use other objects such as a knife, scraper, spatula, etc. The body of the refrigerator is not designed for such loads. A small scratch can cause a breakage.

If the chamber is not defrosted, the frozen layer begins to act as an insulator, since it has a lower coefficient of heat transfer. As a result, the following problems occur:

  • In older models of units where the freezer is located on top, the freezing chamber gradually freezes and spoils the foods in it;
  • If ice is left on for a long time, the walls are covered with a thick layer of ice and, as a result, the ice chamber volume is reduced
  • The frozen layer slows down the air cooling, which changes the operating mode of the cooling system and overloads it;
  • Due to the increased load, the equipment wears out faster, the risk of failures and breakdowns increases, and the service life of the household appliance decreases;
  • Compressor run time increases, increasing energy consumption and resulting in additional costs.

Ignoring ice in the freezer for a long time can also lead to more serious consequences. Increased load results in risk of wiring damage and fire.

Procedure every 6 or 12 months, frequency depends on the refrigerator model and operating conditions. If the unit is equipped with good heat protection and the door is rarely opened, it is defrosted after a considerable period of time. Old units in the average mode of use in winter clean the frost once in 3 months, in summer. once in 2 months.

In today’s world, manual defrosting is practically unheard of. After all, innovative developments are constantly coming up with new means to combat the “ice coat”.

Why the manual defrosting of the freezing chamber is a disadvantage

Automatic defrosting in the refrigerator occurs regularly. Freezers without a No Frost system are cleaned of ice and snow by hand. There are models that have two temperature regulators. one for the freezer and one for the fridge compartment. In this case, it is possible to defrost the freezing chamber separately. In order to preserve the frozen food during this time, they are put into the fridge. If there is only one regulator, the appliance has to be defrosted completely. The procedure is carried out 1-2 times a year, in older models more often. once in 2-3 months.

What is an automatic fridge defrost and how does it differ from manual defrosting

Below we will tell you what it is. automatic defrosting of the fridge compartment. The first type is a drip system. It is used in most modern models and only in cold storage rooms. It is notable for its simplicity and efficiency. The evaporator (cooling element) is located behind the rear wall of the unit and has a drain installed underneath. When the compressor is running, there is a formation of ice. When it stops working, the ice melts and the droplets go down the drain. From there, the water flows into a special tray which is located on the motor, where it evaporates. This occurs gradually and unobtrusively.

Types of procedure

The Know Frost Refrigerator defrosts automatically, without any direct involvement of the human being: the system controls the evaporation of humidity and melting of the ice.

  • Partial. only one of the chambers (freezer compartment) is equipped with the system. Refrigerator defrosting is performed by the drip type;
  • full. the system covers both chambers, defrosting. by wind type.

REFERENCE! There are refrigerator models with a system that combines the principles of wind and drip defrosting.

Windy type

Evaporator in electrical appliances in the enclosure behind the back of the unit. Cold air is blown from the inside of the refrigerator by the built-in fan, which condenses on contact with the evaporator and settles on its external walls.

Refrigerator stops working for a few minutes, the heater turns on and the condensate disappears from the surface of the evaporator. After that the motor is switched on and the cycle repeats.

How Does Miele’s NoFrost Work?

  • Food must be stored in closed containers or wrapped in food film, as it can dry out;
  • High cost of the refrigerator;
  • Increased noise level during operation of the appliance and electricity consumption.

Drip type

Frost formed on the evaporator (the device is also located on the rear wall of the refrigerator) melts after the engine is turned off. Water leaks through a channel into a special container, where it evaporates as a result of exposure to warm air.

  • Low cost of refrigerators with this type of defrosting;
  • reliability and practically complete elimination of frost formation in the refrigerator.
  • Drip type defrosting only applies to refrigeration chambers;
  • defrosting requires more time and disconnection of the appliance from the network.

How to get rid of unpleasant odors?

Unpleasant smells in the device are usually caused by improper storage of food (failure to respect the rules of commodity composition, storage of spoiled food, etc.).д.).

To get rid of the “aroma”, first of all, find out and eliminate the cause of its occurrence.

The following methods can help eliminate pungent odor from the refrigerator:

  • Mix vinegar and water in equal proportions and wash the inner walls of the chamber;
  • Crush 20-30 tablets of activated charcoal, pour it on plates or in bags of gauze cloth, put the remedy inside the refrigerator;
  • well “absorb” various aromas crushed citrus peels (lemon, orange), black tea, sugar, rice, vanilla, coffee beans (grind them beforehand): as in the previous cases, place them in bags of linen cloth, gauze, put inside the household appliance.

Special balls for refrigerators which are sold in stores of household chemicals effectively remove even the most corrosive smell.

The mineral components they contain eliminate the unpleasant “aroma” and prevent mold. The balls work for 3-4 months, after this period the preparations should be replaced with new ones.

TIP! Do not forget to take care of the appliance if you need to leave for a long time: defrost, wash the device and leave it turned off, with the door open.

Check the food in the unit periodically, discard food that has expired, store food in lidded containers.

Cleanliness in the refrigerator is not only a guarantee of your health, but also of the long service life of your kitchen appliances.

What is the principle of the technology?

It is impossible to imagine today a modern refrigerator without an automatic defrosting system. The practicality of the functionality has long been appreciated by housewives, and manufacturers continue to improve it.


  • It does not require frequent defrosting. defrosting once a year is enough to maintain the smooth operation of the equipment;
  • No temperature difference. the upper and lower shelves of the chamber are equally cold, which allows you to provide equal freshness to all products;
  • Can work in both the refrigerator and freezer compartments.


  • Does not relieve the user from defrosting;
  • Makes more noise due to the operation of an additional fan;
  • The evaporator “steals” part of the chamber space, which makes it less roomy;
  • consumes more electricity;
  • Has a higher cost.

Defrosting systems in all modern refrigerators belong to one of two types. drip or wind. Both systems prevent formation of ice, but they differ fundamentally in the principle of functioning.

Drip type

This type of defrost is sometimes referred to the “No Frost” system, although the drip system is only indirectly related to it.

In refrigerators of the drip type, on the back wall there is an evaporator to which the channel for blowing the refrigerant is connected. Under the action of the refrigerant, the evaporator becomes cooler than other surfaces, becoming a sort of trap for moisture. Moisture droplets settle only on the evaporator and gradually crystallize.

A special sensor monitors the amount of frost accumulated on the evaporator. As soon as the layer becomes too large, the automatic system shuts down the compressor. Evaporator begins to heat up, ice melts and flows in the form of droplets into the allotted container, from where it evaporates on its own.

Frosted type

The evaporator is also responsible for the operation of the wind-driven system. The part is installed in the back wall and concealed under the casing so it won’t come into contact with the food. The evaporator is equipped with a small fan that disperses cold and warm air streams inside the chamber.

Thanks to the continuous ventilation frost does not have time to settle on the walls, and the ice droplets quickly thaw without forming a layer of ice. Melt water flows through separate channels and evaporates over time.

No Frost system compares favorably to drip auto-defrost because of its compatibility with freezers.

How to wash a fridge without defrosting

It is not necessary to defrost the fridge “Samsung” “No Frost” or any other brand completely to maintain order. If there is an unpleasant smell or spilled liquid foods, you can simply wipe the walls and shelves, pre-disconnect the device from the mains.

Do not defrost more than once a year unless necessary. Frequent defrosting of the No Frost refrigerator can damage the device.
