Defrosting the freezer in an Atlant two-compressor refrigerator: complete instructions with nuances

Two-compressor refrigerators Atlant - a popular solution for those who value independent control of the refrigeration and freezer cameras. However, even the most advanced equipment requires regular maintenance, and defrosting the freezer remains a mandatory procedure. Unlike single-compressor models, here the process has its own characteristics: you can turn off only the freezer compartment without affecting the refrigerator compartment, but it is important not to disrupt the operation of the system No Frost (if it is provided).

In this article we will look at how to properly defrost a freezer in a two-compressor Atlant - from preparation before final drying, we will take into account the nuances for models with manual defrosting and No Frost, and also tell you what mistakes most often lead to breakdowns. We will pay special attention to the safety and security of products. If you have never encountered defrosting such equipment or doubt your actions, this guide will help you avoid typical problems.

Why does a two-compressor refrigerator Atlant need to be defrosted?

Many owners mistakenly believe that equipment with a system No Frost or two compressors does not require defrosting. In fact, even such models require periodic maintenance - just less often than refrigerators with a drip system. Here are the key reasons:

• 🧊 Ice accumulation in the drainage system. Over time, ice plugs form in the condensate drainage channels, which interfere with normal air circulation and increase the load on the compressor.
• ❄️ Reduced cooling efficiency. A thick layer of frost on the evaporator acts as a heat insulator, causing the compressor to work longer and consume more electricity.
• 🦠 Bacteria reproduction. Moisture and food residues in the freezer create a favorable environment for microbes, even if the temperature remains low.
• 🔧 Prevention of breakdowns. Regular defrosting helps to notice malfunctions in time: for example, oil leaks under the compressor or uncharacteristic noises.

For models Atlant with manual defrosting, it is recommended to carry out the procedure every 3–6 months (depending on the intensity of use). For No Frost - once every 12–18 months, but not less often! Ignoring this rule may lead to failure of the thermostat or fan.

Preparing for defrosting: what needs to be done before turning off the refrigerator

Improper preparation is one of the main causes of breakdowns after defrosting. To avoid problems, follow this algorithm:

1. Adjust the temperature in advance. The day before defrosting, set the freezer to the lowest possible temperature (usually this -24°C or Super Freeze). This will help the food stay cold longer.
2. Prepare food containers. Use thermal bags, ice containers, or wrap food in several layers of newspaper. Do not put meat and fish in plastic bags - they can tear from the weight.
3. Turn off the water supply (if you have a dispenser or ice maker). In models Atlant with the function Ice Maker be sure to drain the water from the tank, otherwise it will freeze in the hoses.
4. Remove all shelves and drawers. They need to be washed separately in warm water and soda (do not use abrasive detergents!).

Pay special attention to products that cannot be re-frozen: for example, defrosted meat, shrimp or semi-finished products. It is better to cook or eat them immediately. If there are products in glass containers (for example, sauces) in the freezer, remove them first - the glass may burst due to temperature changes.

⚠️ Attention: If your refrigerator Atlant is equipped with a system No Frost, but ice still forms on the back wall of the freezer, this is a sign of a malfunction of the fan or defrost heater. In this case, defrosting will not help, diagnostics are required!

Step-by-step instructions: how to defrost a freezer in a two-compressor Atlant

The main advantage of two-compressor models is the ability to turn off only the freezer compartment, leaving the refrigerator to work. This saves time and energy. Here's how to do it correctly:

Step 1: Turning off the freezer

In refrigerators Atlant with two compressors (for example, series XM or NM), the freezer compartment is controlled separately thermostat. To turn off only it:

1. Find on the control panel (usually inside the freezer or on the top of the case) a button or switch labeled Freezer or a snowflake icon ❄️.
2. Turn the control to OFF or press the hold button (in electronic models).
3. Make sure that the freezer compressor has stopped working - it can be identified by vibration and a characteristic hum (the second compressor responsible for the refrigeration chamber should continue to work).

Step 2: Accelerating defrosting

Do not wait until the ice melts on its own - this may take up to 10–12 hours. Proven methods will help speed up the process:

• 💨 Fan. Direct air flow from a table fan into an open freezer. Do not use a hair dryer - it can melt plastic parts.
• 🍲 Pots with hot water. Place containers of boiling water on the freezer shelves (no higher than 60–70°C!) and close the door for 15–20 minutes. Repeat the procedure until the ice begins to break off.
• 🧂 Saline solution. For an especially thick layer of frost, mix 2 tbsp. spoons of salt with 1 liter of water and apply to the ice with a sponge. Salt will speed up the melting, but do not overdo it - an aggressive solution can damage metal parts.

Under no circumstances try to break off the ice with a knife or other sharp objects! This can damage evaporator (thin aluminum tubes), and repairs will cost half the cost of the refrigerator. If the ice does not come off, let it melt naturally.

Step 3: Removing water and drying

After the ice melts, there will be water at the bottom of the freezer. It must be removed as quickly as possible to avoid corrosion of metal parts:

1. Use soft rags or sponges - they absorb moisture better than paper towels.
2. Wipe the drainage hole (usually located on the back wall) with a cotton swab dipped in alcohol. This will prevent clogging.
3. Leave the freezer door open for 1–2 hours to dry completely. At this time, you can wash the shelves and seal.

Cleaning and disinfection after defrosting

Defrosting is the ideal time for general cleaning. Here's how to properly clean your freezer:

For disinfection, you can use specialized products (for example, Bagi or Cillit Bang for refrigerators), but avoid compounds with chlorine - they spoil the plastic and leave a persistent odor. After cleaning, wipe all surfaces dry and leave the freezer to ventilate for another 30–40 minutes..

⚠️ Attention: If the sealing rubber has lost elasticity or become cracked, it must be replaced. Check the tightness with a simple test: press a sheet of paper between the door and the body. If it pulls out easily, the seal is worn out.

Typical errors during defrosting and their consequences

Even experienced users sometimes make mistakes that lead to breakdowns. Here are the most common of them:

• ❌ Use of sharp objects to remove ice → Damage to the evaporator and leakage of freon. The repair will cost 5–7 thousand rubles.
• ❌ Defrosting with the compressor on → Overheating of the motor and failure of the start relay (a characteristic sign is that the refrigerator does not turn on after defrosting).
• ❌ Ignoring the drainage hole → Clogged and leaking water under the refrigerator, which leads to corrosion of the case.
• ❌ Turning on the freezer immediately after washing → Formation of condensation on electronic boards (in models with a display, this can cause a short circuit).

Another common problem is incorrect connection after defrosting. For example, if you accidentally turn your freezer to maximum mode immediately after washing, the compressor may not be able to cope with the load. Optimal algorithm:

1. Connect the refrigerator to the network.
2. Set the temperature in the freezer to -16°C.
3. Wait 1-2 hours until the system stabilizes, and only then load products.

What to do if after defrosting the freezer does not freeze?

If the compressor is humming, but the cold is not getting cold, check:

1) Is the drainage hole clogged (water can block air circulation).

2) Is the seal damaged (a slightly open door leads to freezing of the evaporator).

3) Is the thermal fuse tripped (in this case, the refrigerator needs to be rebooted - turn it off for 10 minutes).

If the problem persists, the control board has probably failed or compressor - diagnostics are required at a service center.

How long does defrosting take?

The defrosting time depends on several factors:

• 🧊 Ice thickness. A layer of 1–2 cm will melt in 2–3 hours, and a layer of 5–7 cm will take up to 8–10 hours.
• 🌡️ Room temperature. In a cool kitchen (below +20°C), the process will take 30–50% longer.
• 🔄 Acceleration method. Without auxiliary means (fan, hot water), defrosting can last for a day.
• 🔌 Type of system. Freezers with No Frost defrost faster, but require mandatory drying of the ventilation ducts.

To speed up the process, you can combine methods, but do not overdo it. For example, if you use both a fan and pots of water, the ice will melt in 3-4 hours. However, make sure that the temperature inside the freezer does not rise higher +40°C as this may damage the thermostat.

How often do you need to defrost a two-compressor unit Atlant?

The frequency of defrosting depends on the model and operating conditions. Here are some rough recommendations:

If you often open the freezer or store a lot of wet food in it (for example, fresh vegetables without packaging), defrost it on 20–30% more often. It is also worth considering climatic conditions: in regions with high humidity (for example, in St. Petersburg), ice grows faster than in a dry climate.

⚠️ Attention: Details of technical recommendations (for example, defrosting frequency for a specific model Atlant) may vary. Check them in the operating instructions for your refrigerator.

FAQ: Frequently asked questions about defrosting two-compressor refrigerators Atlant

Is it possible to defrost a freezer without turning off the refrigerator compartment?

Yes, in two-compressor models Atlant the freezer and refrigeration compartments operate independently. You can turn off only the freezer while leaving the refrigerator on. To do this, use a separate temperature regulator for the freezer (usually it is indicated by the ❄️ icon or the inscription Freezer).

What to do if after defrosting the freezer does not turn on?

First check:

1. Is the refrigerator connected to the network (sometimes the plug may fall out sockets).
2. Has the thermal fuse tripped (wait 10-15 minutes and try turning it on again).
3. Is the power cord or plug damaged.

If the freezer still does not work, but the light inside is on, the problem may be in the compressor or start relay. In this case, contact the service center.

How to defrost a freezer Atlant with the No Frost system?

Although No Frost implies automatic defrosting, it still needs to be cleaned every 1-1.5 years. manually:

1. Turn off the freezer (it is not necessary to turn off the refrigerator compartment).
2. Remove all products and shelves.
3. Wipe the walls and ventilation grilles with a soda solution (do not use abrasives!).
4. Blow drainage hole and check the operation of the fan (it should rotate freely).

Carefully inspect the evaporator (usually hidden behind the back panel) - if there is ice on it, this is a sign of a malfunction of the defrosting system.

Is it possible to use a hair dryer to speed up defrosting?

No, this is dangerous! from a hair dryer can:

• Melt plastic parts (especially the seal).
• Damage electronic components (in models with a display).
• Cause overheating of the compressor if it accidentally turns on.

It is better to use a fan or pots with warm (not hot!) water.

How long can food be stored without cold during defrosting?

It depends on the type of food and storage conditions:

• Meat and fish - no more than 2 hours at room temperature (it is better to use a thermal bag).
• Frozen vegetables/fruits - up to 4 hours (they retain temperature longer).
• Dairy products and semi-finished products - no more than 1.5 hours.

If defrosting is taking longer, place the food in a bowl with cold water and ice.
