Modern household appliances of the brand Don are deservedly popular due to their reliability and affordable cost, however, even the most advanced units require regular maintenance. Many owners often wonder how often and how exactly the ice removal procedure should be carried out in order to avoid damaging the equipment and extend its service life. Unlike old Soviet models, modern refrigerators may have different cooling systems, which directly affects the algorithm of user actions during maintenance.
Incorrect defrosting can lead to serious consequences, including failure of the compressor or damage to internal plastic panels. That is why it is important to clearly understand what type of refrigerator is in your kitchen: manual defrosting, drip system or No Frost. In this article, we will analyze in detail all the nuances of the process so that you can safely maintain the cleanliness and efficiency of your device.
Ignoring the need to remove ice crust can cause increased energy consumption and deterioration in the quality of food storage. Ice acts as an excellent heat insulator, forcing the compressor to work hard, trying to maintain the set temperature. Let's figure out exactly when the moment comes for carrying out preventive maintenance and what is required for this.
Determining the type of defrosting system in Don models
Before taking active steps, it is necessary to accurately identify the cooling system of your unit, since the approaches to maintenance are radically different. Refrigerators Don can be equipped with a static system that requires manual intervention, or more modern automatic moisture removal technologies. An incorrect determination of the type of system can lead to wasted time or, conversely, to breakdown due to lack of necessary care.
A static system, often called a “crying” or drip system in the freezer, involves the formation of ice on the back wall, which must be periodically removed manually. In such models, moisture condenses on the evaporator, freezes, and then, when the compressor is turned off, flows into a special chute. However, in the freezer compartment of such devices, the ice does not disappear anywhere and builds up in layers, requiring your attention.
The system No Frost (or “no frost”) works on the principle of forced air circulation, in which moisture is removed outside the chambers into a special evaporator, where it is removed. Owners of such models defrost do not need a refrigerator in the classical sense of the word, since the automation itself regulates the evaporator defrosting process. However, sanitary cleaning and preventive maintenance are still required, albeit much less frequently.
How to distinguish No Frost from a drip system?
Visually in the No Frost freezer you will not see an open evaporator (grid) on the back wall - it is usually hidden by a plastic panel. Also, in such models there are often no grid shelves on the freezer doors, since strong cold air blows there.
To accurately determine the type of device you have, refer to the user manual or find the technical sticker located inside the chamber or on the back wall of the case. The model will be indicated there, and from it you can determine the presence of technology Total No Frost or partial implementation of the system. If the documentation is lost, pay attention to the presence of ice crust: if over a month the layer of ice in the freezer exceeds 5-7 mm, then there is no automatic defrosting in this compartment.
When it is necessary to defrost: signs and frequency
The frequency of the procedure directly depends on the operating conditions, humidity in the room and the volume of loaded products. Equipment manufacturers Don recommend focusing not only on calendar dates, but also on the visual condition of the cameras. There are a number of signs that clearly indicate that you can no longer delay defrosting.
The main indicator of the need for cleaning is the thickness of the ice layer on the walls of the freezer. If you notice that the ice has taken up a significant amount of space, narrowing the usable volume, or the door no longer closes tightly due to ice on the seal, the process must be started immediately. Also, an alarming signal is the appearance of extraneous noise during the operation of the compressor or a humming sound that has not previously been observed.
- ❄️ The thickness of the ice on the walls of the freezer exceeds 5-7 millimeters.
- 🚪 The refrigerator door does not fit tightly to the body due to frozen ice on the seal.
- 💧 The appearance of puddles of water under the refrigerator or inside the lower section.
- 📉 A noticeable decrease in the quality of freezing food or an increase in the operating time of the compressor.
On average, for models with manual defrosting, the procedure is recommended to be carried out once every 4-6 months. However, if you often open the door, load warm food, or have high humidity in the room, the intervals may be reduced to 2-3 months. Ignoring these deadlines leads to the fact that the compressor is forced to work almost without interruption, which reduces the life of the refrigeration unit.
Step-by-step instructions: how to defrost a refrigerator Don
The defrosting process requires sequential steps to avoid food spoilage and damage to the internal elements of the refrigerator. You should start with preparation: clear some space around the unit, prepare containers for collecting water and rags for wiping the floor. It is important to act methodically, without trying to speed up the process by physically affecting the ice.
The first step is always to disconnect the device from the electrical network. Unplug the power cord and remove all food from the chambers. It is better to place perishable goods in thermal bags with ice or take them out to the balcony (in winter) so that they do not have time to defrost while the process is in progress. After this, open the doors of all chambers and leave them in this position.
☑️ Defrosting algorithm
Next it is necessary to ensure outflow melting water. Some models Don have special drain holes, but most often the moisture simply drains onto the floor. Place flat trays under the bottom of the refrigerator, and place absorbent rags or towels on the floor. If the ice does not melt on its own, you can speed up the process by placing bowls of warm (not hot!) water inside the chambers.
⚠️ Attention: It is strictly forbidden to use a hair dryer, hot water from a kettle (pour directly onto the plastic) or sharp objects to chip ice. A sudden temperature change can cause cracks in the evaporator, and mechanical impact is guaranteed to damage the cooling system, after which repairs will be very expensive.
After all the ice has melted, it is necessary to thoroughly wash the internal surfaces of the chambers. Use a soft sponge and a weak solution of soda or a special refrigerator cleaner. Pay special attention to the rubber seals on the doors - dirt and mold often accumulate in the folds, which must be carefully removed. The final step will be to thoroughly wipe all surfaces dry with a soft cloth.
What not to do: common mistakes when defrosting
The desire to quickly complete the procedure often leads to fatal mistakes that can disable the equipment forever. The most common mistake is using knives, screwdrivers or spatulas to break off ice. The aluminum evaporator, hidden behind a plastic panel or located open, has very thin walls, and it is easy to break them with a sharp object.
Another dangerous mistake is the use of electrical appliances to heat the air inside the chamber. Hair dryers, fan heaters, and other heating devices create uneven heat, which can warp plastic parts, melt shelf fasteners, and even damage wiring. In addition, moisture from melting ice entering a working electrical appliance creates the risk of a short circuit.
| Action | Consequence | Risk of breakdown |
|---|---|---|
| Chipping ice with a knife | Damage to the evaporator, freon leak | High (circuit replacement required) |
| Heating with a hairdryer | Deformation of plastic, overheating of wiring | Medium (replacement panels, wiring) |
| Pouring boiling water | Cracks in the body, burns to hands | Medium (replacing internal containers) |
| Turning on a wet refrigerator | Short circuit, board failure | High (electronics repair) |
Also, do not turn on the refrigerator immediately after you have wiped off visible water. Moisture could remain inside the plastic panels and in hard-to-reach places, which needs time to evaporate. Leave the doors open for a while after washing to make sure the internal chambers are completely dry.
fridge care after defrosting
Proper care after completion of the defrosting procedure is no less important than the process itself. After you have washed and dried the compartments, let the refrigerator idle for about 30-60 minutes before loading food. This will stabilize the temperature regime and make sure that the equipment functions correctly.
Pay attention to the condition of the drainage hole, if it is provided for in the design of your model. Don. It often becomes clogged with crumbs or mucus, which leads to stagnation of water in the refrigerator. You can clean it with a special flexible brush or a regular cotton swab, carefully inserting it into the hole and making several rotational movements.
To maintain freshness and prevent the appearance of unpleasant odors, you can use natural absorbers. Place an open container with activated carbon, soda or a special refrigerator freshener inside the chambers. This will help maintain a pleasant microclimate and absorb excess odors from food.
Regularly check the condition of the rubber seals. They should be clean and pliable after defrosting. If you notice that the rubber has cracked or lost its shape, it should be replaced, as a leak in the chamber will lead to the constant formation of ice and increased load on the compressor. The seals can be lubricated with special silicone grease or glycerin.
Features of defrosting double-chamber and single-chamber models
The design of the refrigerator plays a key role in organizing the defrosting process. Single-chamber models, where the freezer compartment is a small compartment inside the main chamber or a separate door, require complete emptying of food. In such devices, the cold is distributed evenly, and the entire volume has to be defrosted at once.
Two-chamber refrigerators Don with a system Low Frost or partial No Frost may have features. In some cases, the freezer compartment requires manual defrosting, while the refrigerator compartment is serviced automatically. It is important not to confuse these zones and not to try to “help” the automation in the refrigerator compartment, since the water there should drain on its own.
If you have a model with two compressors, it is theoretically possible to defrost the chambers one by one, turning off only one of them. However, manufacturers do not recommend (doing this) unless absolutely necessary, as this creates additional load on the control system. It is better to completely defrost all chambers at the same time, it is more hygienic and efficient.
⚠️ Attention: In two-chamber models with one compressor and an air distribution system, defrosting one chamber while the other is running is impossible. A power outage will affect the entire unit.
When defrosting two-chamber models, pay attention to the joints between the chambers. Often it is in the joints of plastic panels that moisture and dirt accumulate. Thorough drying of these areas will help avoid the appearance of mold and unpleasant odors in the future.
Frequently asked questions (FAQ)
Is it possible to defrost the Don refrigerator in winter by placing it on the balcony?
It is strictly not recommended. Sudden temperature changes can damage plastic parts and seals. In addition, operation of the compressor at low ambient temperatures (below +5°C) is prohibited by the instructions, since the oil in the compressor thickens, which leads to breakdown.
How long does complete defrosting take?
The time depends on the thickness of the ice and the temperature in the room. Typically the process takes from 3 to 8 hours. Do not try to artificially speed up this process, as this is the main risk of damaging the evaporator.
Is it necessary to defrost a refrigerator with a No Frost system?
Technically, there is no need to remove ice, since the system does it automatically. However, once every year or two it is recommended to carry out general cleaning with unplugging to wash and disinfect the internal surfaces.
What to do if the refrigerator does not turn on after defrosting?
Check the integrity of the power cord and the presence of electricity in the outlet. If everything is fine, moisture may have gotten into the contacts of the thermostat or control board. Let the device dry for a few more hours in a warm room. If the problem is not solved, you will need to call a specialist.
Is it possible to wash the refrigerator with soapy water?
It is not advisable to use ordinary soap, as it can leave a smell and film. It is better to use a solution of baking soda (1 tablespoon per liter of water) or special products for household appliances that do not contain abrasives and chlorine.
