Two-compressor models Atlant have earned a reputation as reliable equipment that can operate for years without serious failures. However, even the highest quality system No Frost or Low Frost requires periodic maintenance. Owners often wonder: is it really necessary to defrost such a unit if it is equipped with modern moisture removal technologies? The answer is clear: yes, hygienic defrosting is necessary to maintain cleanliness and efficient operation of the equipment.
The process of turning off a two-compressor machine has its own nuances, which differ from the control of single-chamber or older models. Here it is important not only to let the ice melt, but also to correctly distribute the load on the system when restarting. Ignoring the rules This can lead to an unpleasant odor, the growth of bacteria, or even failure of the seals.
In this article we will analyze in detail the algorithm of actions that will help you carry out the procedure safely. You will learn why dual-circuit system requires special attention to the sequence of turning on the cameras and how to avoid typical mistakes made by inexperienced users.
Design features of two-compressor models
The main difference between such refrigerators is the presence of two independent circuits cooling. One compressor is responsible for the freezer compartment, and the second is responsible for the refrigerator compartment. This allows you to set different temperature conditions and turn off one camera while the other continues to operate normally. It is this feature that dictates the specifics of defrosting.
In models with a system Full No Frost visible ice does not form on the evaporators, since moisture is removed through drainage. However, condensation and frost can accumulate in areas where cold air flows through ducts or on door seals. In addition, over time, a thin layer of ice forms in the hidden cavities of the housing, which interferes with heat transfer.
⚠️ Attention: Despite the presence of an automatic defrosting system, manufacturers recommend carrying out complete hygienic cleaning with disconnection from the network at least once a year.
Understanding the design helps to avoid panic when one of the compressors is turned on after turning on starts later than another or works intermittently. This is normal behavior for intelligent system temperature control.
Preparation for the defrosting procedure
Before starting active actions, it is necessary to prepare the workplace and empty the chambers of the contents. This is the most time-consuming stage and requires advance planning. Find a place to store food in advance so that it does not have time to spoil while the process is underway.
Gather the necessary equipment: you will need absorbent rags, basins for collecting water and, possibly, an old towel for the floor. If the kit came with a special grid for collecting melt water, be sure to use it by installing it in the lower part of the freezer. Atlant refrigerator There was a special grid for collecting melt water, be sure to use it, installing it at the bottom of the freezer.
- 🧊 Prepare thermal containers or cooler bags for temporary storage of food.
- 🧹 Find a soft sponge and a non-abrasive detergent for internal cleaning in advance.
- 🔌 Make sure that the power cord is long enough to easily unplug from the outlet.
It is important to check the condition sealing rubber bands even before you start washing. If they are cracked or dirty, defrosting is the ideal time to clean or replace them. Dirt on the seal breaks the tightness, forcing the compressors to work harder.
Step-by-step instructions: how to do it correctly turn off
The process of turning off a two-compressor unit must be sequential. First you need to unload all the products from both chambers. Then you should turn the temperature controls to the “0” or “Off” position, if such a function is provided by the design of your Atlanta.
Only after this can you unplug the cord from the socket. Sudden pulling of the plug under load can cause sparking, so we first stop the electronics and then break the power circuit. The doors of both chambers must be left open for air access.
☑️ Checklist before defrosting
If your model allows you to turn off the cameras independently, you can take advantage of this advantage. For example, the freezer is defrosted first while the refrigerator compartment continues to operate, and vice versa. However, completely defrosting the entire device at once is usually more effective for general cleaning.
Do not forget to remove all removable elements: shelves, drawers Cristal, baskets and egg containers. They need to be washed separately in warm water, since a sharp temperature change (for example, washing ice glass in hot water) can lead to cracks.
Natural and accelerated defrosting: what to choose
The safest method for equipment Atlant natural thawing. Ice melts at room temperature without stressing the plastic elements and evaporator tubes. This process can take from 10 to 24 hours depending on the thickness of the ice and the temperature in the room.
Many users try to speed up the process by using a hairdryer or placing bowls of hot water inside. Using a hairdryer is acceptable, but with great caution: the air flow should be warm, not hot, and it should be directed not at the plastic, but at the ice crust. Overheating of the plastic may deform the internal panels.
| Method | Time | Safety | Efficiency |
|---|---|---|---|
| Natural | 12-24 hours | High | Medium |
| Warm water (bowls) | 2-4 hours | Medium | High |
| Hair dryer | 30-60 min | Low (risk of overheating) | Very high |
⚠️ Attention: It is strictly forbidden to use sharp objects (knives, screwdrivers) to chip ice. One careless movement can puncture the evaporator, and repairs will cost more than a new refrigerator.
If you choose the method with bowls of hot water, be sure to place a towel or wooden board under them. Contact of the hot bottom of the cookware with the plastic bottom of the chamber can leave indelible marks or melted areas.
Why can’t you pour boiling water directly onto ice?
Direct contact of boiling water with an ice crust creates a sharp thermal shock. Plastic becomes brittle in the cold and can crack due to temperature changes. In addition, steam from boiling water can damage electrical contacts and sensors located inside the case.
Cleaning and disinfecting internal chambers
While the ice is melting, it’s time to start cleaning. Use a weak solution of baking soda or a special refrigerator cleaner. Aggressive chemicals with chlorine or acids can damage the coating of the internal plastic and leave a persistent chemical odor, which is then absorbed into the food.
Pay special attention to the drainage hole, which is usually located on the back wall of the refrigerator compartment. It often becomes clogged with crumbs and mold. You can clean it using a special brush or soft wire wrapped in cotton wool. After cleaning, run warm water over the canal to make sure it is clear.
Rubber seals on the doors must be wiped thoroughly, removing dirt from the folds. This is where black mold most often settles. For disinfection, you can use a weak solution of vinegar, but after it the surface must be wiped with clean water.
- 🍋 Citric acid perfectly eliminates unpleasant odors and degreases surfaces.
- 🧼 Do not use abrasive sponges - they leave micro-scratches where dirt accumulates.
- 💧 Carefully wipe all surfaces dry before assembly to avoid the formation of new ice.
After washing, leave the doors open for another 30-40 minutes so that the insides refrigerator finally dry and the smell of the detergent disappears. A humid environment is an ideal condition for the development of bacteria.
Correct startup after defrosting
Starting a two-compressor system requires following a certain sequence. First, plug in only the freezer compartment (or the one where the main compressor is located, if the model allows separate control via the panel). Let it work for 1-2 hours without loading food.
Then you can turn on the second camera. This phased start-up reduces the peak load on electrical network your home and allows each compressor to return to operating mode smoothly. If you turn on both circuits simultaneously immediately after inactivity, they can work without shutting down longer than usual, raising the temperature.
Make sure that the temperature controls are set to the correct position. For the main chamber this is usually 3-4 divisions (about +4...+5°C), for the freezer - maximum freezing mode or standard -18°C. After the refrigerators get cold, you can carefully load the food.
Common mistakes when servicing equipment
One of the most common mistakes is trying to turn on the unit immediately after washing, without waiting for the electrical contacts and sensors to dry. Moisture inside the case can cause a short circuit or corrosion of the contacts.
Another mistake is ignoring the tilt level check. If the refrigerator is not level, the doors may not close tightly on their own. This leads to the constant entry of warm air inside, the formation of a “fur coat” and increased load on compressors.
Some users forget to lubricate the seals with silicone grease after each general cleaning. Without lubrication, the rubber dries out, cracks and no longer holds the cold. This is a consumable item that requires care to extend its service life.
⚠️ Attention: If after defrosting and turning on the refrigerator makes an unusual noise, knocks or does not freeze for 4-5 hours, do not attempt to repair it yourself. Contact an authorized service center.
Table of recommended maintenance intervals
The frequency of defrosting depends on operating conditions and room humidity. Below are indicative data that will help plan the care of your equipment Atlant.
| System type | Recommended frequency | Signs of need | Procedure time |
|---|---|---|---|
| Drip (crying) | 1 time every 4-6 months | Ice on the back wall | 8-12 hours |
| No Frost / Low Frost | 1 time every 12 months | Smell, dirt, ice on the doors | 4-8 hours |
| Combined | 1 time every 6 months | Decreased efficiency | 10-14 hours |
Compliance with these intervals ensures that your refrigerator will consume less electricity and last the period stated by the manufacturer. Regular care is the key to food freshness and the health of your family.
Is it possible to defrost a refrigerator without unplugging it?
Technically, if you have a model with the function of turning off one chamber, you can defrost it one by one. However, complete defrosting with power off is necessary for safety and thorough cleaning. It is prohibited to leave the device turned on during active washing with water.
What to do if a strong odor appears after defrosting?
Use special odor absorbers, activated carbon or just a saucer with ground coffee. If the smell does not go away for several days, mold may have penetrated into hard-to-reach places, such as under the plastic or in the drainage channel, and disassembly is required.
Do compressors need to be lubricated with oil after defrosting?
No, compressors in refrigerators Atlant are sealed and do not require user maintenance. You only need to lubricate the rubber door seals with a special compound or glycerin to maintain elasticity.
Why does the refrigerator not turn off for a long time after defrosting?
After defrosting, it is warm inside, and the system takes time (sometimes up to a day) to cool the volume of chambers and products to the set temperatures. This is normal operation, not a breakdown.
