Owners of modern household appliances are often faced with the need to defrost, and two-compressor models Atlant are no exception. The main advantage of this design is the possibility of independent operation of the refrigeration and freezer compartments. This allows you to carry out maintenance of one chamber without disturbing the temperature regime in the second, which is especially important when storing large volumes of products.
However, despite the technical autonomy, the process requires a clear understanding of the operating principles of the system No Frost or Low Frost, if they are present, or a classic drip system. Errors in the sequence of actions can lead to failure of the electronics or damage to the seals. In this article, we will analyze in detail the algorithm of actions that will help you quickly and safely complete the procedure.
It is worth noting that ignoring the need for defrosting leads to the formation of an ice coat, which significantly increases energy consumption and reduces the efficiency of freezing. The compressor begins to wear out, trying to compensate for the loss of cooling capacity through a layer of ice. Therefore, regular maintenance is not just a matter of cleanliness, but a necessity to extend the life of the unit.
The principle of operation of a two-compressor system
The key feature of refrigerators Atlant with two compressors is the presence of two separate circuits. One circuit is responsible for cooling the refrigerator compartment, and the second is responsible for the freezer compartment. It is this engineering feature that makes isolated defrosting possible. When you turn off one of the circuits, the second continues to function normally, maintaining the set temperature.
It is important to understand the difference between moisture removal systems. In models with manual defrosting or system Low Frost ice builds up on the walls of the evaporator, hidden behind the back panel or at the bottom of the chamber. In systems No Frost moisture is removed automatically, but even they require preventive washing and removal of ice in hard-to-reach places once a year.
⚠️ Attention: Never try to speed up the defrosting process using a hairdryer or other heating devices aimed directly at the plastic. A sharp temperature change can cause microcracks in the evaporator housing, which will lead to freon leakage.
Technical documentation for most models Atlant confirms that the compressor operating cycles are synchronized electronically, but manual control allows you to break this cycle for a specific circuit. This gives the user complete control over the service process without the risk of spoilage of food in the next compartment.
Why does ice interfere with the operation of the refrigerator?
The ice crust acts as a heat insulator. The evaporator ceases to effectively remove heat from the chamber, sensors record the increase in temperature and command the compressor to work longer. This leads to overheating of the motor windings and increased energy consumption.
Preparation for the defrosting procedure
Before starting any manipulations, it is necessary to properly prepare the workspace and the unit itself. First, empty the freezer of food. If there is perishable food in the refrigerator compartment, make sure the door is closed to keep it cold. For freezer products, prepare containers with refrigerant or blankets for thermal insulation in advance.
Next, you need to ensure the safety of the electrical appliance. Turning off the power is a mandatory step, but there is a nuance in dual-compressor models. You don’t just need to unplug the plug from the socket, but also correctly complete the current work cycle. It is recommended to turn the temperature regulator to position "0" or "Off" 15-20 minutes before physically disconnecting from the network.
- ❄️ Prepare in advance basins for collecting melt water and rags for wiping the floor.
- 🧼 Prepare a mild detergent and sponge for subsequent cleaning.
- 🔌 Make sure the power cord is dry and has no visible damage to the insulation.
- 🧤 Wear rubber gloves if you plan to use cleaning products.
Check the stability of the refrigerator. During defrosting, a significant amount of water may leak from the system, and if the floor is slippery, the unit may move. Place old towels or absorbent diapers under your feet. This will protect the floor covering from swelling and damage.
☑️ Preparation checklist
Step-by-step instructions: how to turn off only the freezer
The process of turning off the freezer in two-compressor Atlanta depends on the type of control panel. In mechanical models, each circuit has its own thermostat. They are usually located inside the cameras or on the top panel of the case. You need to find a regulator that is responsible specifically for the freezer compartment (often it is marked with a snowflake or numbers from 1 to 7).
In electronic models, control is carried out through the display. Here the algorithm may differ. Often you will need to press and hold the setting button of the appropriate camera until the power off symbol appears or the minimum temperature is reached. In some modifications Atlant with a control system EcoMode it is enough to simply set the temperature in the freezer to the maximum value (for example, +5°C or the "Vacation" mode), although completely turning off the compressor is more reliable.
| Control type | Action for freezer | Indication | Reaction time |
|---|---|---|---|
| Mechanical | Rotate the knob to position "0" | Relay click | Instantly |
| Electronic (buttons) | Holding the "Temp" button | Display flashing | 3-5 seconds |
| Touch | Touch the camera icon | Light signal | 1-2 seconds |
| Mixed | Switch on body | The lamp lights up | Instantly |
After you have turned the control to the off position, wait about 5-10 minutes. The compressor should stop working and you will hear a characteristic click from the thermostat. Only after this can you safely remove the plug from the socket if you are planning open defrosting, or leave it on if you are using the automatic defrosting mode (although for complete cleaning it is better to completely de-energize).
⚠️ Attention: In some older models Atlant the thermostats may be doubled or have a common power button. Carefully study the instructions for your specific model so as not to turn off the refrigerator entirely.
Acceleration of the ice thawing process
The natural thawing process can take from 3 to 10 hours depending on the thickness of the ice cover and the temperature in the room. If you only unplugged the freezer, some heat from the refrigerator compartment may penetrate through the partition, but not enough to defrost quickly. There are several safe ways to speed up the process.
The most effective and safe method is using containers with warm water. Pour warm (not boiling water!) water into bowls or baking trays and place them on the freezer shelves. Close the door tightly. The warm steam generated inside the enclosed space will begin to actively act on the ice crust, softening it much faster than air at room temperature.
You can also use a fan to direct a stream of air at room temperature into the open freezer. This will ensure constant air circulation and prevent the formation of stagnant cold zones. However, make sure that dust or animal hair does not get into the chamber.
It is strictly forbidden to use sharp objects (knives, screwdrivers, ice picks) to chip ice. Aluminum evaporator tubes in refrigerators Atlant are located very close to the inner wall of the chamber. One careless movement will lead to a puncture, leakage of freon and expensive repairs, which are often not economically feasible.
Cleaning and disinfection of the chamber
After all the ice has melted and the water has drained, the stage of hygienic processing begins. Even if the chamber visually seems clean, during operation bacteria and mold could settle in the micropores of the plastic, which cause an unpleasant odor. Use a weak solution of baking soda (1 tablespoon per liter of water) or special products for cleaning refrigerators.
Thoroughly wipe all surfaces, including shelves, drawers and, most importantly, the rubber door seal. It is in the folds of the seal that dirt most often accumulates. After wet cleaning, be sure to wipe all surfaces dry with a clean rag. Residual moisture can quickly turn into a new ice crust when turned on.
- 🧽 Use a soft sponge to avoid scratching the plastic.
- 🚿 Do not pour water directly on the walls - it is better to wet the cloth.
- 👃 To eliminate the smell, wipe walls with half a lemon or place activated carbon tablets.
Pay special attention to the drainage hole, if it is provided for in the design of your model. In two-compressor Atlantakh it may be located on the back wall of the freezer. Clean it with a special brush or soft wire to ensure free flow of condensate in the future.
Starting and setting up after defrosting
When the chamber is washed and dried, you can start starting. Plug in the refrigerator. If you used a mechanical thermostat, first set the knob to the middle position (usually number 3 or 4). A sudden start at maximum cooling will create unnecessary stress on the compressor that has just started.
Allow the freezer to idle for 1-2 hours. During this time, the temperature will drop to operating values and the system will stabilize. Only after this can you start loading products. If you load warm food at once, the compressor will work non-stop, trying to cool a large volume, which is harmful to the motor.
⚠️ Attention: Specifications may vary slightly depending on the year of manufacture of the model. Check the product data sheet to clarify the recommended temperature conditions.
Check the tightness of the door. After defrosting and cleaning, the seal could move. The door should close tightly, without gaps. If you notice that it does not fit tightly, you may need to adjust the hinges or replace the seal.
Frequent errors and troubleshooting
Despite the simplicity of the procedure, users often make mistakes that nullify all efforts. One of the most common is an attempt to turn on the refrigerator immediately after washing, without waiting for the internal surfaces to dry. Moisture that gets into electrical contacts or sensors can cause a short circuit or incorrect operation of the electronics.
Another mistake is ignoring signs of a malfunction. If, after defrosting, the refrigerator Atlant hums louder than usual, does not turn off, or, conversely, does not gain temperature, this may indicate problems with the refrigerant or thermostat. In such cases, independent repair is dangerous, it is better to contact a service center.
Also, users often forget to check the condition of the ventilation holes between the cameras (if they are present in a particular model). Their blockage with food disrupts air circulation, which leads to uneven cooling and ice formation in unexpected places.
What to do if a strong smell appears after defrosting?
If the smell does not disappear after washing with soda, try using professional odor absorbers or an ozonizer. Also check if water has entered the space behind the back panel, where the insulation may be located - in this case, complete drying will be required within 24 hours.
Is it possible to defrost a freezer if there is a lot of food in the refrigerator compartment?
Yes, in two-compressor models it is safe. The refrigerator compartment will maintain its temperature as its compressor continues to operate. The main thing is not to keep the refrigerator door open for too long while loading/unloading food from the freezer.
How often do you need to defrost a two-compressor Atlant?
The recommended frequency is 1-2 times a year. However, if you notice that the layer of ice on the walls exceeds 5-7 mm, defrosting must be carried out immediately, regardless of the timing.
