Brand refrigeration equipment Atlant has proven itself to be reliable and durable, however, even the most advanced equipment requires regular maintenance. Owners often wonder about the need and frequency of defrosting, especially considering that the model range includes both classic systems and modern solutions No Frost. Ignoring this process in models with a drip system can lead to a decrease in cooling efficiency, increased energy consumption and even compressor failure.
Many users mistakenly believe that modern units do not need defrosting at all, or, conversely, carry out this procedure too often unnecessarily. Key factor here is the type of system installed defrosting, which directly affects the algorithm of actions. Understanding the design features of your device will allow you to avoid typical mistakes, such as chipping ice with sharp objects or using a hairdryer, which can cause irreparable damage to the evaporator.
In this guide, we will look in detail at how to properly prepare the equipment for the procedure, what actions are strictly prohibited and how often this needs to be done for different modifications. Compliance with the technology will extend the life of the seals, preserve the original heat transfer characteristics and ensure the hygiene of the internal space.
Determining the type of defrosting system
Before taking active steps, you must clearly identify what type of cooling system is installed in your unit. The model range Atlant covers a wide range of technologies, from time-tested “crying” evaporators to advanced full automation systems. It depends on whether you will need to completely unplug the appliance or just wash the shelves.
Device with manual defrosting or a drip system (often called Drop System) accumulate frost on the back wall of the refrigerator compartment. During operation of the compressor, this frost periodically thaws, and the water flows into a special groove. However, over time, especially if there is high humidity or doors are opened frequently, the layer of ice may become too thick to evaporate. In the freezer compartment of such models, ice constantly builds up and requires mechanical removal.
The system No Frost (or Frost Free in combined versions) works on a different principle. The fan drives dry cold air through the chambers, and the automation periodically turns on the heating element to defrost the hidden evaporator. In such models, ice does not form inside the chambers in principle. If you see ice in a refrigerator with the declared system No Frost, this is a signal of a malfunction, and not of normal operation.
⚠️ Attention: An attempt to defrost a working refrigerator No Frost by turning off the power does not make technical sense and is performed only for the sake of sanitization. Ice should not form there.
To accurately determine the type of system, refer to the product data sheet or look for a sticker with technical characteristics, usually located inside the chamber or on the back wall of the case. Also, the type of system is often indicated in the model name: the presence of the letters NF or the phrase “No Frost” directly indicates that there is no need for manual defrosting.
Technical characteristics and model designations may vary depending on the year of manufacture. It is recommended to check the details of your specific modification in the official user manual.
Preparation for the defrosting procedure
Proper preparation is half the success and a guarantee of food safety. You should start by emptying the cameras of their contents. If there are few products, they can be temporarily transferred to a nearby refrigerator or taken out to the balcony (in winter), packed in thermal bags or blankets to maintain the temperature.
After emptying the shelves, you must disconnect the unit from the power supply. To do this, remove the plug from the socket. Strictly prohibited pull the wire to remove the plug, as this may damage the contacts or insulation. Only after completely turning off the power can you begin to remove removable elements: glass shelves, plastic containers, vegetable boxes and ice trays.
☑️ Preparation checklist
Prepare a place in advance to collect melt water. Despite the fact that the design includes moisture inlets, if a large volume of ice intensively melts, water can overflow them and flow onto the floor. Place several large terry towels or rags around the device that absorb moisture well. It is also worth preparing a basin or wide container if you plan to collect water quickly.
It is important to ensure air access to the internal space. Leave the refrigerator and freezer doors completely open throughout this process. This will speed up the natural melting of the ice and help any unpleasant odors disappear if they have already been absorbed into the plastic.
Step-by-step defrosting process
The safest method recommended by manufacturers is natural thawing. After you have turned off the device and opened the doors, all you can do is wait. Depending on the thickness of the ice crust and the room temperature, this process can take from 3 to 24 hours. You should not rush things by using aggressive methods that can damage the delicate inner coating of the chambers.
During the melting process, make sure that the moisture collectors and placed rags are filled. If necessary, change the rags to dry ones or pour out the collected water. If an ice plug has formed in the drain hole, you can carefully clean it with a special brush or soft wire, but this must be done with great care so as not to pierce the tube.
Is it possible to use a hair dryer?
The use of a hair dryer is permissible only in extreme cases and with precautions. The air flow should be warm, but not hot, and it should be directed not directly at the plastic, but at the ice mass from a distance of at least 30-40 cm. Prolonged exposure to hot air can deform plastic parts or damage the seals.
After all the ice has melted and the water has melted, you must thoroughly wipe the internal surfaces dry. Pay special attention to corners, panel joints and rubber seals. A humid environment is an ideal place for bacteria and mold to grow, so dryness before turning on is critical.
⚠️ Attention: Never use a knife, screwdriver or other sharp object to chip ice. Damage to the evaporator, which is often located immediately behind the plastic wall, will lead to a refrigerant leak and expensive repairs, which are often not economically feasible.
Care for seals and internal surfaces
The defrosting period is the ideal time for general maintenance cleaning While the chambers are empty and dry, you should wash all removable parts (shelves, drawers) in warm water using a mild detergent. Aggressive chemicals, abrasive powders or solvents cannot be used, as they can damage plastic or glass.
Special attention is required sealing rubber bands on the doors. Over time, dirt, crumbs and mold accumulate in the folds of rubber, which impairs the seal of the door. Wipe the elastic bands with a soft sponge soaked in a weak solution of vinegar or soda, and then wipe dry. To maintain the elasticity of the rubber, you can treat it with a special agent or ordinary glycerin.
The inner walls of the chamber should also be washed. Baking soda solutions or special refrigerator care products are well suited for disinfection. After wet cleaning, be sure to let the surfaces dry completely or wipe them with a dry cloth before connecting to the network.
Frequency of defrosting refrigerators Atlant
The regularity of the procedure directly depends on the type of system and operating conditions. For models with manual defrosting (where the ice must be removed manually), an interval of 3-6 months is considered optimal. However, if you notice that the layer of ice in the freezer has exceeded 5–7 mm, defrosting should be done immediately, without waiting for the planned date.
Units with a drip system in the refrigerator compartment require defrosting the freezer approximately once every six months. The refrigeration chamber itself in such models is defrosted automatically, but once a year it is still recommended to turn it off for thorough washing and disinfection.
Below is a table that helps you navigate the frequency of maintenance depending on the model:
| System type | Refrigeration camera | Freezer | Signs of necessity |
|---|---|---|---|
| Manual | Once every 6 months. | Once every 3-4 months. | Ice layer > 5 mm |
| Drop | Automatic | Once every 6 months. | Increasing "fur coat" |
| No Frost | Automatic | Automatic | For washing only |
| Combined | Automatic | Once every 6-8 months | Decreased efficiency |
It is worth considering that frequent opening of doors, storing food in open containers (which increases the humidity inside) and a loosely closed door accelerates the formation of ice. In such conditions, you will have to defrost the appliance more often.
Typical errors when defrosting
Ignorance of technical nuances often leads to situations where an attempt to help the equipment turns into a breakdown. One of the most common mistakes is using a hairdryer on maximum power or using hot water to speed up the process. A sudden temperature change can cause cracks in the plastic case or deformation of the evaporator.
Another mistake is turning on the device immediately after the ice has melted. The compressor and refrigerant need time to return to normal and the interior walls to dry completely. Turning on a wet refrigerator can cause a short circuit in the electrical contacts.
Also, users often forget to check the drain hole after defrosting. If there is debris or a piece of ice left in the drainage channel, condensation will subsequently begin to accumulate at the bottom of the refrigerator compartment and flow out, damaging the floor and creating dampness.
⚠️ Attention: Do not leave the refrigerator to defrost unattended for a long time if there are children or pets in the house. Open doors and puddles of water on the floor can cause injury or damage to property.
Completing the process and first start-up
After thoroughly cleaning and drying all surfaces, you can begin assembly. Replace all shelves, drawers and containers. Make sure they are secured correctly and do not wobble. Close the refrigerator doors tightly.
Now the device can be connected to the mains. However, don't rush to load the products right away. Let the refrigerator idle for 2 to 4 hours. This is necessary to ensure that the correct temperature conditions are established inside the chambers. Loading warm foods or a large volume of food immediately after switching on will cause the compressor to work with overload, trying to cool the entire volume.
Check the operation of the unit: listen to how the motor works, whether there are any extraneous noises, whether it cools well enough. If everything is in order, you can carefully fill the chambers with products, observing the rules of product proximity and not blocking the ventilation holes.
Possible problems after defrosting
Sometimes after the defrosting procedure, users are faced with the fact that the refrigerator has stopped freezing or started working incorrectly. This is often due to water getting into the system or an ice plug blocking the capillary tube. In such cases, it may be necessary to defrost again during the day to completely evaporate moisture from hard-to-reach places.
If the problem persists, the temperature sensor or thermostat may have been damaged during the cleaning process. It is also possible that freon may leak due to careless handling of a sharp tool. In such situations, independent repair is impossible and you need to call a specialist.
Proper and timely care of the refrigerator Atlant is the key to its long service. Regular defrosting not only keeps food fresh, but also saves energy, since a thick layer of ice acts as a heat insulator, causing the compressor to work harder.
Is it possible to defrost the Atlant refrigerator without unplugging it?
Absolutely not. Defrosting is possible only when the device is completely disconnected from the power supply. A running compressor will try to maintain the temperature, which will make the ice melting process endless, and can also lead to engine failure due to overload or moisture getting on the electrical contacts.
How long can you not turn on the refrigerator after defrosting?
The minimum downtime before turning it on again is 2 hours, but an interval of 3-4 hours is considered optimal. This time is necessary for the internal elements to completely dry and the pressure in the cooling system to stabilize.
What to do if a plastic smell appears after defrosting?
An unpleasant odor may be a result of the use of aggressive chemicals when washing or water getting on the heating elements (if a hair dryer was used). It is necessary to rinse the chambers again with a soda solution and ventilate the refrigerator well with the doors open during the day.
Is it necessary to defrost an Atlant refrigerator with the No Frost system?
Technical defrosting (removing ice) is not required for such models, since they are equipped with an automatic moisture removal system. However, once every 6-12 months it is recommended to turn off the appliance to carry out sanitary treatment, wash shelves and remove dust from the condenser at the back.
