The back wall of the Biryusa refrigerator is freezing: 7 reasons and what to do

Have you noticed an ice “coat” on the back wall of the refrigerator Biryusa? This is not just an aesthetic problem - a thick layer of ice impairs heat transfer, causes the compressor to wear out and increases energy consumption by 20-30%. In older models Biryusa (for example, 130K or 140K) ice could appear due to design features, but even in modern units with the system No Frost the rear wall is sometimes covered with frost. What's the matter and how to fix it?

In this article we will look at all possible reasons from trivial misuse to serious breakdowns requiring the intervention of a specialist. You will learn how to diagnose the problem yourself, what manipulations can be done without risk to the equipment, and in which cases it is better not to experiment. We will also present unique data on typical “weak points” of Biryusa refrigerators of different generationswhich are rarely mentioned in general manuals.

1. Why ice forms on the back wall of the Biryusa refrigerator: general reasons

Icing on the back wall is always a consequence of an imbalance between heat and cold inside the chamber. Normally, moisture in the air condenses on the evaporator (located just at the back) and is then removed through the drainage system. If this process is disrupted, the condensate freezes, forming ice. Here are the key factors that lead to this:

• 🔹 Incorrect temperature. In models Biryusa with a drip defrosting system (for example, Biryusa 18C or Biryusa 22K), the back wall may become covered with frost if the thermostat is set to maximum cooling (below +4°C).
• 🔹 Clogged drainage hole. If the water does not go into the pan, it accumulates and freezes. A common problem after defrosting is when crumbs or food particles get into the hole.
• 🔹 Wear of the door seal. Even microcracks in the rubber lead to the entry of warm air, which condenses on the cold wall.
• 🔹 Overload with food. If the refrigerator is full to capacity, air circulation is disrupted and moisture settles on the back wall.

In models with No Frost (for example, Biryusa 110 or Biryusa 132) frost on the back wall - alarm signal. This may indicate fan malfunction, freezing of the drainage tube or leak freon. In such cases, you cannot do without diagnostics.

2. Diagnosing the problem: how to understand what exactly is wrong

Before fixing something, you need to determine the root of the problem. Carry out a simple inspection:

1. Check the door seal. Close the door and place a piece of paper near the joint. If it pulls out easily, the seal is leaking. In models Biryusa older than 2010, the rubber often hardens and cracks.
2. Estimate the number of products. If the refrigerator is more than 70% full, and the food is close to the back wall, this disrupts heat transfer.
3. Look at the drainage hole. It is located at the bottom of the back wall. If water has accumulated there or ice is visible, the system is clogged.
4. Check the temperature settings. Optimal mode for Turks — +4…+5°C in the refrigerator compartment and -18°C in the freezer. If it is set lower, the compressor works without interruption, and the wall freezes.

If after checking everything is in order, but the ice continues to grow, the problem may be technical malfunction:

⚠️ Attention! If a refrigerator Biryusa with a system No Frost freezes from the inside and the fan does not make noise, this is a sign of its breakdown. Do not try to disassemble the back panel yourself: in these models there is a high risk of damaging the electronics.

3. How to remove ice on the back wall: step-by-step instructions

If the problem is not associated with a serious breakdown, you can solve it on your own. Here's what to do depending on the reason:

🔧 1. Cleaning the drainage hole

A clogged hole is the most common cause of ice in models Biryusa 18C, 22K and similar ones. To clean it:

Unplug the refrigerator

Remove all products from the bottom shelf

Carefully clean the hole with a cotton swab or soft wire

Rinse the drainage with warm water using a syringe

Dry the refrigerator for 1-2 hours-->

If ice has already formed, do not try to scrape it off! Place a cloth soaked in hot water on the shelf and close the door for 15–20 minutes. The ice will thaw and it can be removed with a soft sponge.

🔧 2. Replacing or restoring the seal

You can try to “revive” a worn rubber band:

• 🧼 Wash the seal with warm water and soap, then wipe with silicone grease (do not use vegetable oil!).
• 🔥 Heat the elastic with a hairdryer (temperature no higher than 50°C) - this will restore its elasticity.
• 📏 If gaps greater than 2 mm - the seal needs to be changed. For Turkish original elastic bands are suitable Biryusa 8MM-2.101-1 (for old models) or universal 58x590.

🔧 3. Setting the temperature

In refrigerators Biryusa with a mechanical thermostat (for example, Biryusa 6M), the optimal position of the regulator is between 2 and 3. In models with electronic control (Biryusa 132, 140) set:

• Refrigeration camera: +4°C
• Freezer: -18°C (not lower, if not necessary)

⚠️ Attention! In refrigerators Biryusa with a system Frost Free (semi-automatic defrosting) you cannot disable the function Super Cool for a long time. This leads to freezing of the evaporator and, as a consequence, the rear wall.

4. Typical mistakes during defrosting that lead to ice

Many users themselves provoke icing by improperly defrosting the refrigerator. Here's what you can't do:

• ❄️ Use sharp objects to chip ice - it damages the plastic and evaporator tubes. In Turk 130K and similar models the wall is thin, it is easy to pierce it.
• 🌡️ Place hot objects (pots, hair dryers) to speed up defrosting. A sudden change in temperature can damage the seal and electronic components.
• 💦 Do not wipe off the moisture after defrosting. The remaining water freezes and the cycle repeats.
• ⏳ Turn on the refrigerator immediately after defrosting. You need to let it dry for at least 1-2 hours, otherwise the moisture will freeze again.

Proper defrosting Turks looks like this:

1. Unplug the refrigerator.
2. Remove all food and shelves.
3. Place a tray to collect water.
4. Wait for natural thawing (do not speed up the process!).
5. Wipe all surfaces dry cloth.
6. Leave the door open for 1-2 hours to dry.
7. Turn on the refrigerator and wait until the temperature rises before loading the food.

5. When to call a professional: signs of serious damage

Not all problems can be solved on your own. Contact the service center if:

• 🔧 The refrigerator Biryusa works without stopping, but does not cool (the back wall is covered with ice) - this is a sign freon leak or capillary tube clogged.
• 🌬️ In models with No Frost fan noise is not heard - most likely, it is broken and the cold is not distributed evenly.
• ⚡ The refrigerator receives an electric shock or sparks when turned on - this may be due to damage to the electronics due to ice.
• 📉 The temperature in the chamber is unstable (either too low or too high), and frost appears and disappears on the back wall - faulty thermostat or temperature sensor.

Average repair cost for Biryusa (for 2026):

⚠️ Attention! If your refrigerator Biryusa was manufactured before 2010, some spare parts (for example, original thermostats or compressors) may be discontinued. Check their availability at the service center to consent for repairs.

6. Prevention of icing: how to prevent the problem

To prevent the back wall of the refrigerator Biryusa from becoming covered with ice, follow these rules:

• 📅 Defrost the refrigerator at least once every 3 months (even if there is system No Frost).
• 🥩 Do not place hot foods into the refrigerator. Wait until they cool down to room temperature.
• 🧊 Do not overload the freezer. The optimal load is no more than 2/3 of the volume.
• 🔄 Check the seal every six months. At the first signs of wear (cracks, deformation), replace it.
• 🌡️ Control the temperatureUse a separate refrigerator thermometer to make sure the thermostat is working. correctly.

For models Biryusa with a drip defrosting system (18C, 22K), it is useful to wipe the back wall once a month with a weak solution of vinegar (1 tablespoon per 1 liter of water). This prevents the formation of mold and improves it. heat exchange.

What to do if the Biryusa refrigerator freezes up after moving?

After transporting the refrigerator (especially lying down), oil from the compressor can get into the cooling system. This leads to unstable operation and icing. Solution: leave the refrigerator in an upright position for 12-24 hours before turning it on. If the problem persists, you need a technician to check the compressor.

7. Frequently asked questions about Biryusa refrigerators and frost

❓ Why is the back wall freezing in the Biryusa 130K refrigerator, even though it is frozen? with a drip system?

In the model Turk 130K (and similar ones), the drip system works effectively only with proper operation. If you put warm foods in the refrigerator, often open the door or do not defrost it in time, the moisture does not have time to evaporate and freezes. Also check if the drainage is clogged - in this model it often becomes clogged due to its narrowness. holes.

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

You can use a hair dryer, but with caution: keep it at least 30 cm from the surface, set the minimum temperature and do not direct the air flow towards the seal or electronic elements B. refrigerators Biryusa with plastic walls (for example, 6M) there is a high risk of plastic deformation from hot air.

❓ Why does the back wall freeze again after replacing the thermostat?

This may be due to several factors:

• Poor quality thermostat (especially if non-original spare parts were used).
• Incorrect setting of the new thermostat (needs to be calibrated according to the instructions for your model).
• Problems with the temperature sensor (in electronic models Biryusa it may give incorrect readings).
• Freon leak that was not eliminated before replacing the thermostat.

If the problem recurs, a comprehensive diagnosis is required.

❓ Which Is the seal suitable for Biryusa 22K?

For the model Biryusa 22K the original seal is suitable Biryusa 8MM-2.101-1 (for the refrigerator) and Biryusa 8MM-2.102-1 (for the freezer) If the original cannot be found, you can use universal seals with a magnetic one. insert, for example 58x590 or 60x600. The main thing is that the length matches the perimeter of your door.

❓ Why is everything fine in the freezer, but the back wall freezes in the refrigerator compartment?

This is a typical problem for two-chamber refrigerators Biryusa with one compressor Reasons. may be as follows:

• Faulty switching valve between the chambers (cold goes only to the freezer, and moisture freezes in the refrigeration chamber).
• Clogged capillary tube in the area responsible for the refrigeration chamber.
• Does not work fan (in models with No Frost).
• The temperature in the refrigerator compartment is set too low (below +3°C).

In most cases, a specialist diagnosis is required.
