There is an opinion that modern refrigerators, including those with the No Frost system, do not require defrosting. However, from a technical point of view this is wrong. Defrosting helps free both chambers (refrigerator and freezer) from the accumulation of frost and ice, which impairs the quality of food cooling and disrupts the operation of the unit. Defrosting is also carried out for sanitary and hygienic purposes. There are several methods that make cleaning a household appliance easier: defrosting the refrigerator using hot water, a fan and other unusual devices.
Why defrost the refrigerator and how long does it take to defrost?
There are several reasons why you need to defrost the device:
- To maintain the functionality of the device
- To prevent mold growth
- For disinfecting shelves and doors
- To eliminate odor
Many of us have encountered the fact that the refrigerator often smells bad. This is due to the fact that a product is stored in the chamber that has expired and should be thrown away. In addition, unpleasant odors can mix.
The frequency of defrosting depends on the model of the device. If these are old household appliances, such as Minsk, Dnepr, etc., then defrosting is carried out once every 4 weeks. If these are more modern models, then it is enough to clear ice accumulation once every six months. If this is a No Frost system, then defrosting should be done extremely rarely. The technical documentation states that such models defrost independently. But it is still worth disinfecting the camera.

Safety rules for non-standard defrosting methods
The first thing you should do when working with the device is to unplug it from the outlet . After all, water is a good conductor of electricity and this can have a negative effect on you. Second, but no less important, is care when working with heating devices. Do not point them at the connecting rubber, as it may melt. Deformation will allow warm air to easily enter the refrigerator. Subsequently, a new “fur coat” will appear much earlier.
After work, thoroughly wipe everything around, including the internal shelves. Turn on the refrigeration unit, but do not put food in immediately, wait until the temperature drops to normal, otherwise the food will spoil.
To summarize, we can say that cleaning with accompanying actions will take about one day. However, they must be sacrificed in order to save time and money in the future. And for quick defrosting you can use a hairdryer or fan heater.

Is it possible and how to defrost a refrigerator with a hairdryer and hot water?
All of these products are suitable for defrosting a refrigerator.
Defrosting methods:
- Hot water. It should not be poured onto the camera itself. Just put a bowl of hot water inside and close the door. After a while, the air inside the chamber will heat up and the refrigerator will quickly shrink.
- Hair dryer. It is necessary to direct a stream of warm air at ice formations. This will significantly speed up the thawing of the ice.
- Hot water bottles. You need to fill the hot water bottles with hot water and put them in the freezer to let them melt.

Useful tips
Whatever defrosting method is chosen, you should first prepare a sufficient number of dry rags. The ideal choice would be old towels, soft fabrics, sponges. A well-absorbing rag must be placed under the tray into which the melt water flows. This will prevent water from getting onto the floor.
When defrosting the refrigerator, you need to consider the following recommendations:
- You cannot start defrosting without turning off the refrigerator.
- After partial thawing, the ice can be removed using a wooden spatula.
Attention! It is forbidden to pick out ice with sharp objects. For example, a kitchen knife. It is so easy to damage the walls, and such damage cannot be repaired.
- When the walls are cleared of ice, as shown in the photo, it is recommended to wash them well with a soapy solution using any dishwashing liquid.
- Before turning it on, wipe the walls of the freezer with a dry towel.
- After turning it on, it is better to let the freezer work for 2-3 hours without food and only after a while fill it with contents. The desired temperature inside will be established only after a day, so you should minimize the number of door openings.
Housewives should take into account that the formation of ice on walls more than 5 mm thick more often than six months may indicate a malfunction of household appliances. The most common cause is a loose fit of the rubber gaskets on the door, as shown in the photo. Rapid ice formation is also caused by hot foods left in the freezer of a two-compartment refrigerator. This disrupts heat exchange in the device, which leads to overheating of the motor.
Before defrosting a freezer or a two-chamber refrigerator, it is recommended that you read the instructions included with the appliance itself, and only then choose the most suitable method for quick defrosting. The methods described above are often used in practice and are considered very effective and efficient.

Causes of ice formation and the need for defrosting
You need to get rid of frost and ice in the refrigerator and freezer regularly . The device cannot constantly maintain cold inside, since when the door is opened, warm air enters inside and the temperature in the compartments rises.
When the degrees rise above normal, the compressor turns on and again reduces the temperature to the required level. The water in the air of the refrigeration chamber freezes, forming snow and ice build-up on the evaporator and the walls of the chambers. Ice disrupts air exchange and forces the compressor to work constantly at full strength, which leads to increased energy consumption.
Important! Incorrect operation of the compressor due to ice crust reduces the service life of the household appliance. Soon you will need either an expensive compressor replacement or the purchase of a new refrigerator.
The main reasons for increased ice formation:
- turning on maximum cooling in hot weather;
- long stay in the “superfreeze” mode;
- breakdown of the air temperature sensor in the chambers;
- breakdown of the thermostat in the evaporator;
- clogged drainage hole (refrigerator with a drip system);
- failure of the ice defrosting mode;
- freon leak (the device works non-stop);
- wear of the rubber seal - warm air enters the chambers;
- clogged capillary pipeline - refrigerant circulation is difficult;
- breakdown of the solenoid valve between the compartments (in two-chamber refrigerators).
Special attention and caution when defrosting and washing requires a rubber seal , if damaged, the process of ice freezing accelerates.

Refrigerator that does not need to be defrosted: name
Recommended defrosting methods
The refrigerator must be defrosted regularly, regardless of the type of system. Multilayer ice forms over time on any surface
Refrigerators with different defrosting systems
Modern models are equipped with ice prevention systems: drip and No Frost. Depending on this, the defrosting methods will be different.
Drip defrosting system
Most middle-class refrigerators are equipped with a drip defrosting system. Freezing the freezer compartment from ice is carried out manually. The principle of operation of the drip system is alternating freezing and thawing, when the compressor is automatically activated and turned off at a certain time.
When the device is turned on, the temperature in the refrigerator drops, and a layer of frost appears on the back of the device. When the ice thickness reaches 5-7 mm, the device needs to be defrosted.
When the compressor is turned off, condensation forms on the evaporator, which then flows into the pan through special drains. As a result of defrosting, the layer of frost completely disappears, and the walls of the device remain completely dry.
No Frost
No Frost is a more advanced defrosting system in premium models. Cooled air passes into both chambers through a fan. The compressor and evaporator are located in a special compartment: moisture concentration and evaporation occurs here.
It is a mistake to think that devices with a No Frost system do not need defrosting. If the frost is not removed in time, the rubber bands on the doors begin to wear out, and warm air gets inside the chambers. This leads to rapid wear of the device. In addition, stains and streaks from food appear in the compartments, and small crumbs accumulate in the cracks.
Freezer
To defrost your freezer separately, temporarily transfer all foods to the main compartment or remove them completely from the refrigerator. If this is not possible, then a few hours before turning off the device, set the temperature regulator to maximum: this will help preserve food longer without additional cooling.
To properly defrost the freezer, follow the algorithm:
- Turn the thermostat to “0”.
- Disconnect the freezer from the electrical outlet.
- Remove all food items from the freezer.
- Remove the melt water tray and rinse it thoroughly.
Then leave the freezer door open until the layer of frost has completely melted. To speed up the process, you can use a special plastic scraper to remove thawing ice. After completely freeing yourself from ice and frost, proceed step by step:
- Wipe the inside of the freezer with a soft cloth and vinegar or soapy water.
- Walk along all the walls of the chamber with a dry cloth, wiping thoroughly until there is no moisture left on the surface.
- Leave the device for several hours to dry completely.
- Connect the freezer to the mains and return to the set temperature (usually medium).
When the chamber has cooled down to the desired temperature, place all the products back.
Step-by-step algorithm
Every housewife should know how to properly defrost a refrigerator.
Important! Natural thawing is the safest defrosting method.
To do this, we suggest that you read the detailed instructions:
- Set the operating mode control lever to the zero position.
- Unplug the power cord from the outlet. Remember, you cannot defrost a refrigerator that is turned on, this will disrupt the operation of the compressor and damage the unit.
Sealed bags keep food fresh while defrosting
- Completely empty the device of its contents. During the cold season, food can be taken out onto the balcony. When it’s warm, place it in a large basin and cover it with a thick blanket to keep it cold.
- Remove all removable elements (shelves, drawers, containers).
- Check the melt water collection tray. If there is none, place rags and containers.
- Give the ice time to melt. During the natural defrosting process, ice melts on average in 2–8 hours. But in general, how long you need to defrost the refrigerator will depend on the thickness of the ice layer .
- After all the ice has melted, you need to thoroughly rinse the refrigerator and wipe it dry.
- Upon completion of cleaning, return all shelves and drawers to their place, set the temperature and turn on the device.
Important! You can load food back only after the refrigerator has reached the desired temperature.
Use soft cloths to clean the interior surface
You can defrost the freezer in the refrigerator by following the same instructions. But in two-compressor models you do not have to completely turn off the entire unit; it is enough to turn off the power to only one of the chambers.
Features of defrosting 2-chamber refrigerators
Defrosting a refrigeration unit with two compressors is even easier and more convenient than a classic single-chamber appliance. The owner of a two-chamber model has the opportunity to defrost the compartments either one by one or simultaneously.
Defrosting should be done more often if there is a high level of humidity in the room.
In the first case, the upper camera is turned off first. At this time, all products from it can be folded into the lower part. And having finished with the upper compartment, do everything the other way around. This is much more comfortable, because there is no need to think about where to put the supplies. But there is an obvious disadvantage - separate defrosting will take twice as long.
The last stage of defrosting
- After completely cleaning the device from frozen masses, you need to carry out a detailed washing of the device. Mix 100 gr. baking soda with 80 ml. table vinegar (6%), add 20 g. rosemary ether. Scoop a little product onto a kitchen sponge and thoroughly wipe the refrigerator walls and door seals. Finish drawers and shelves with the same composition. Leave for 30 minutes.
- After this period, prepare a solution: mix 2 packets of vanilla sugar with 400 ml. warm water, wait until the granules dissolve. Remove the previous mixture with paper towels, then dip a cloth into the solution and wipe the entire cavity of the device. Wash the drawers, seals and shelves under the shower, moisten them with vanilla solution.
- You have already freed yourself from any aromas that might have arisen after defrosting. Now you need to dry the cavity of the device, containers and containers. Wipe with a dry cloth to remove any additional moisture. Don't forget to thoroughly dry the seals; they will absorb water and become loose.
- Insert the shelves into the refrigerator openings, turn on the fan and direct the air flow through the center of the appliance. Wait about 20 minutes, then place containers for vegetables and eggs on the middle shelves and dry them too.
- Wipe the floor covering around the refrigerator, eliminating possible short circuits. Leave the door open for approximately 1 hour to ensure the appliance is well ventilated. To avoid the appearance of foreign aromas after defrosting, sew a cotton bag and put dry citrus zest in it.
- At the end of the hour, close the refrigerator, connect it to the network, and set the desired temperature. Do not rush to lay out the food; wait until the unit has completely cooled down. Repeat defrosting as often as the type of your refrigerator requires.
What not to do
- Just do not defrost a refrigerator connected to the network. As a result of similar actions, the thermostat will break down, and ice will begin to accumulate several times faster.
- Containers with boiling water are only allowed to be placed in the main cavity of the refrigerator, but not in the freezer.
- Do not use a hair dryer to dry hair when defrosting freezers. The area of ice masses in this compartment is very large, so there will be almost no benefit from a weak hot air flow. But there is a risk of an expected short circuit if, for no apparent reason, drops of water fall on the hair dryer.
- Do not use sharp objects, such as ice picks, when you want to pick out a frozen block. There are situations when, due to inexperience, the owners pierced the walls of the refrigerator, rendering the device unusable.
Defrosting a refrigerator is not difficult if you have good knowledge. Use an oil heater or a “Wind” type device, point the fan at the refrigerator cavity, and place bowls of boiling water.
Correctly turning on the refrigerator after defrosting
It is important not only to defrost the refrigerator correctly, but also to turn it on correctly after the process is completed. Once the device has been cleared of ice, washed of dirt and disinfected of mold and bacteria, it must dry thoroughly; to do this, it is left open for several hours.
After drying, the door is closed, the average temperature level is set and the device is turned on. Products are loaded into a dry and clean refrigerator no earlier than after 1-2 hours so that the air and surfaces of the chambers are cooled evenly. After loading the food, it is recommended not to open the doors for another couple of hours to speed up cooling.
Cleaning refrigerators with automatic defrosting system
Regular cleaning of ice is necessary for older models of refrigerators .
Modern models are equipped with systems (drip, air-drip or No Frost), in which the cold is distributed evenly. As a result, the question of how to defrost the freezer does not arise, since ice does not form. The water simply flows into the drainage hole along the back wall and evaporates. But if this hole becomes clogged, the system fails.
Therefore, devices with an automatic defrosting system will still have to be turned off periodically just to clean the drainage hole and the evaporator tube from accumulated dirt, as well as to wash and disinfect the device itself.
Important! It is not necessary to unplug and defrost the refrigerator if you are leaving for a short time. Modern models have a Holiday function, or something similar, which allows you to keep food at the minimum permissible temperature in the chambers, while reducing energy consumption.
When is defrosting necessary?
A so-called fur coat forms on the walls of the freezer. This is a deposit of ice that can reach up to 5 cm. Moreover, the more frost deposit, the harder it is for the refrigerator to work. The old unit needs to be cleaned much more often, ice covers important parts, and it completely fails. New models have an automatic self-cleaning unit, but despite this, you need to defrost the freezer from time to time.
The procedure becomes necessary if the following problems are noticed:
- The resulting “fur coat” reaches 2 or more centimeters.
- Due to plaque, it is difficult to remove frozen food from the chamber.
- The refrigerator began to freeze worse.
- The “fur coat” makes it difficult to close the door.
Excessive ice formation significantly reduces the service life of equipment.
Defrosting is a mandatory procedure; it is aimed at unloading the refrigerator. Frosty deposits block the passages, so increased work of the compressor is required, as a result of which it wears out faster. In addition, an abundant “fur coat” provokes the formation of bacteria in the freezer and negatively affects the condition of the food. As a result, they quickly deteriorate and an unpleasant odor appears.
