Why the back wall of the refrigerator freezes Eyelid: causes and what to do

You opened the refrigerator Veko and found that the back wall was covered with a thick layer ice or frost? This is not just an aesthetic problem - ice indicates a malfunction in the system. Normally, modern models (including line Veko RCS-100, Veko RKN-120 and others) should maintain uniform cooling without the formation of ice build-ups. If the back wall turns into a “snow cap,” this leads to increased energy consumption, food spoilage and the risk of compressor breakdown.

In this article we will analyze 7 key reasons freezing of the back wall in refrigerators Veko —from trivial operating errors to serious technical malfunctions. You will learn how to diagnose the problem yourself, when you can get by with simple defrosting, and when you need to call a technician. We will pay special attention models with the No Frost system (for example, Veko RCN-180 NF), where ice often indicates a breakdown of the fan or sensors.

We warn you right away: ignore the ice on the rear the wall is not allowed. According to service centers, in 60% of cases, this problem leads to failure of the thermostat or compressor within 6-12 monthsif the root cause is not eliminated. But the good news is that half of the faults can be solved without repair!

1. Violation of operating rules: 3 user mistakes

Most often, the back wall of the refrigerator Veko is covered with ice due to improper use. The manufacturer clearly regulates the operating conditions in the instructions, but many users ignore these rules. Let's consider three typical mistakes:

• 🔥 The door is constantly open or its loose closure. Even a small gap of 2–3 mm allows warm air to enter, which condenses on the back wall. In models Veko with mechanical control (for example, Veko RCS-85) this is especially critical - the thermostat does not have time to adjust the temperature.
• 🍲 Hot foods on the shelves. Placing pots of soup or freshly cooked food will speed up the formation of condensation. In refrigerators Veko with a drip defrosting system (for example, Veko RKN-140) this leads to icing of the drainage hole.
• 🧊 Excessive loading products. If the shelves are packed to capacity, the circulation of cold air is disrupted. As a result, the back wall becomes supercooled, and moisture from the food settles in the form of frost. This is especially true for models with a bottom freezer (for example, Veko RCN-160).

How to check if you are to blame for the problem? Start the refrigerator in test mode: unload it by 70%, make sure that the door closes tightly (check the seal), and do not place warm food inside for 2-3 days. If ice does not form, the reason was in operation.

⚠️ Attention: In refrigerators Veko with electronic control (series Inverter) frequent door openings can disrupt the sensor settings. After such failures, the system sometimes begins to “freeze” the rear. wall, trying to compensate for the heat gain.

2. Malfunctions of the defrosting system: drip vs No Frost

Refrigerators Veko are equipped with two types of defrosting systems: drip (in budget models, for example, Veko RCS-100) and No Frost (in premium ones, for example, Veko RCN-180 NF). systems

In models with with a drip system. data-i="119">drainage hole the most vulnerable spot - drainage hole at the bottom of the back wall. If it is clogged with crumbs or mold, the water does not flow into the tray, but freezes on the spot. It’s easy to check: turn off the refrigerator, let the ice melt and see if the water leaves through the hole. If not, clean it.

In refrigerators Veko No Frost the problem often lies in the fanthat distributes cold air. If it is broken, the back wall stops cooling evenly, and moisture condenses in the form of ice. Listen: if the refrigerator is quieter than usual or you hear it. extraneous sounds (grinding, squeaking) - most likely the fan is to blame.

How to check the operation of the fan in No Frost?

Open the refrigerator and listen: in normal mode, 5-10 minutes after closing the door, the fan should start working (a slight air noise, if you can’t hear it, it means it’s not working). it is faulty or blocked by ice. Do not try to disassemble the system yourself - in models Veko the fan is located behind the rear panel and is attached to the evaporator.

3. Problems with the thermostat and temperature sensors

The thermostat (or thermostat) is the “brain” of the refrigerator that controls temperature. In models Veko it can be mechanical (in old series) or electronic (in new ones, for example, Veko RCN-185 Inverter). If the thermostat fails, the compressor starts working without stopping, freezing the back wall.

Signs of a thermostat malfunction:

• ❄️ The refrigerator does not turn off on its own (the compressor hums constantly).
• 🌡️ The temperature in the chamber drops below +2°C (check with a thermometer).
• 🔄 Ice forms even after complete defrosting and cleaning.

You can check the thermostat with a multimeter (in resistance mode), but this will require access to its contacts. In mechanical models Veko the thermostat is usually required. located next to the temperature control knob. In electronic ones, it is built into the control board, and diagnostics are more difficult.

Another possible reason is malfunction of the temperature sensor (in models with a display). If the sensor transmits incorrect data, the system “thinks” that the refrigerator is warmer than it actually is, and causes the compressor to work harder. This leads to icing on the back wall. In service centers, such a sensor is checked using a diagnostic scanner connected to the control board.

⚠️ Attention: In refrigerators Veko with an inverter compressor (series Inverter), a faulty thermostat can lead to motor overheating. If you notice that the body of the refrigerator has become hot and ice is growing quickly, immediately unplug it and call a technician.

4. Freon leak or clogged capillary tube

If the back wall of the refrigerator Veko is covered with ice unevenly (for example, only in one corner) or the compressor works without interruption, but the temperature in the chamber does not drop below +6...+8°C - possible freon leakage or blockage capillary tube.

Causes of freon leakage:

• 🔧 Mechanical damage to the circuit (for example, during transportation or careless cleaning).
• 🕳️ Corrosion of tubes (relevant for refrigerators older than 7–10 years).
• 🔥 Overheating of the compressor due to a faulty fan (in models No Frost).

It is impossible to independently determine a freon leak - this requires leak detector an experienced technician. However, you can suspect a problem based on the following signs:

• The compressor works without stopping, but the refrigerator does not freeze well.
• On the back wall, ice forms only in one place (where the leak is located).
• After defrosting, the refrigerator does not reach the temperature for a long time.

A clogged capillary tube is another common problem. It can become clogged due to moisture entering the system or the formation of paraffin deposits. In this case. freon does not circulate normally, and the back wall begins to freeze. There is only one solution - flushing the system or replacing the tube.

5. Malfunction of the door seal: how to check and replace

The rubber seal (or magnetic rubber band) ensures the tightness of the refrigerator. deformed or dirty, warm air penetrates inside, causing condensation and ice to form on the back wall. In refrigerators Veko the seal is especially vulnerable in the corners and on the bottom edge of the door.

How to check the seal:

1. Take a sheet of paper (A4 format).
2. Place it between the door and the body of the refrigerator.
3. Close the door and try to pull out the sheet.

If the sheet comes out without resistance the seal is not sealed. Check all sides of the door.

Causes of seal wear:

• 🧽 Pollution (grease, crumbs, mold).
• 🔥 Drying from time (rubber loses elasticity after 5–7 years).
• 🚪 Mechanical damage (cracks, tears).

If the seal is dirty, it can be cleaned with warm soapy water and lubricate with silicone grease (do not use vegetable oil!). If the rubber has lost its shape, try restoring it with a hair dryer (heat the seal for 1-2 minutes, then press the door and let it cool). In case of serious damage, replacement will be required.

⚠️ Attention: B refrigerators Veko with two doors (for example, Veko RCN-200), the seals on the freezer and refrigerator compartments may differ. When replacing, buy components strictly for your model - universal rubber bands often do not provide complete tightness.

6. Malfunctions of the electronic control board

In modern refrigerators Veko (series Inverter, Smart Cooling) is responsible for temperature control electronic control board. If it fails, the compressor may operate in the wrong mode, causing icing of the rear wall. Frequent causes of failures:

• 🌩️ Power surges on the network (especially relevant for regions with unstable power supply).
• 💧 Moisture ingress on the board (due to condensation or leaks).
• 🕰️ Wear of elements (capacitors, resistors) after 5–7 years of operation.

Signs of board malfunction:

• The refrigerator spontaneously turns on/off.
• Appears on the display errors (for example, E1, E2 —for decoding, see the instructions for your model).
• Temperature in the chamber jumps (either too low, then too high).
• Ice forms unevenly, sometimes only in one section.

It is not recommended to repair the board yourself - this is a complex electronic unit. However, you can reset the settings to factory settings, if the refrigerator is equipped with such a function. To do this:

1. Disconnect the refrigerator from the network for 5-10 minutes.
2. Turn it back on and simultaneously press the Super Cool and Super Freeze (in models with a display).
3. Hold them for 10-15 seconds until you hear a beep.

If the reset does not help, contact the service center. The cost of repairing the board in refrigerators Veko ranges from 3,000 to 8,000. rubles (depending on the model and complexity of the breakdown).

7. Incorrect installation of the refrigerator

Even a new refrigerator Veko can freeze if it is installed in violation of the rules, but many users ignore them. data-i="244">(battery, stove, direct sunlight). This causes the compressor to work harder, which leads to icing on the back wall.

• 🔥 Too close to the heat source (battery, stove, direct sunlight). This causes the compressor to work harder, which leads to icing on the back wall.
• 🪟 Poor ventilation (the refrigerator is close to the wall or furniture The minimum distance to the walls is 5 cm from the back and 2 cm from the side). sides.
• ⚡ Uneven floor. If the refrigerator is tilted, the door may not close tightly, letting warm air in.
• 🌡️ Extreme temperatures in the room (below +10°C or above +30°C). In such conditions, the cooling system does not work correctly.

How to install the refrigerator correctly Veko:

1. Choose a place away from the stove, radiator and windows.
2. Make sure the floor flat (use a level). Adjust the legs if necessary.
3. Leave gaps: 5 cm at the back, 2 cm at the sides.
4. Connect to socket with grounding (required for models with electronic control!).

If the refrigerator is already installed, but the back wall is frozen, check the room temperature In models Veko with climate class N (For example, Veko RCS-120N) the optimal ambient temperature is from +16°C to +32°C. At +10°C the compressor may not turn off, which will lead to ice.

What to do if the back wall is already covered with ice?

If ice has already formed, first of all defrost the refrigeratorBut this needs to be done correctly so as not to aggravate the problem:

1. Unplug the refrigerator from the network.
2. Remove all products and place them in a cool place place (for example, in a cooler bag).
3. Leave the door open for 12-24 hours (depending on the thickness of the ice).
4. Do not use a hair dryer or sharp objects to speed up the process - this may damage the plastic or tubes.
5. After defrosting Rinse the internal surfaces with a warm solution of soda (1 tablespoon per 1 liter of water) and wipe dry.

If after defrosting and turning on the refrigerator, ice forms again within 1–2 days - the problem lies in technical malfunction (thermostat, sensor, freon leak). In this case, diagnostics is required.

For models Veko No Frost the defrosting procedure is slightly different:

• Turn off the refrigerator and leave the door open 8–10 hours (instead of 24).
• After defrosting, check the operation fan (should turn on 5-10 minutes after closing the door).
• If the fan does not work or you hear extraneous sounds, call a technician.

⚠️ Attention: In refrigerators Veko with the system No Frost you cannot wash off the ice with water - this can lead to a short circuit of the fan or control board. Use only a dry cloth or sponge.

FAQ: Frequently asked questions about freezing of the back wall in Veko refrigerators

Can I use the refrigerator if the back wall is covered with ice?

Short-term (1-2 days) - yes, but this will lead to increased energy consumption and the risk of compressor failure. Long-term operation with ice reduces the service life of the refrigerator by 30–50%. If the ice does not melt after defrosting, be sure to look for the reason.

How often do you need to defrost a Veko refrigerator with No Frost?

The manufacturer claims that the models No Frost do not require defrosting. However, in practice it is recommended to carry out preventative defrosting once a year this removes accumulated moisture and prevents the formation of mold in the drainage system.

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

This may indicate on:

• Poor quality thermostat (defective or non-original part).
• Problems with temperature sensor or control board.
• Freon leak (if the compressor works without stopping).

Re-diagnosis is required.

Is it possible to replace the door seal yourself?

Yes, if you are confident in your skills. Seals for refrigerators Veko are sold in service centers or on AliExpress (indicate the exact model!). To replace you will need:

1. Remove the old rubber band (carefully so as not to damage the plastic of the door).
2. Clean the groove from glue and dirt.
3. Install a new seal, starting from the upper corners.
4. Warm the rubber band with a hairdryer (for a better fit).

If you are not sure, trust it to the specialist.

How much does it cost to repair a Veko refrigerator if the back wall is frozen?

The cost depends on the reason:

• Replacing the thermostat: 1 500–3 000 ₽.
• Cleaning the drainage system: 1 000–2 000 ₽.
