How a Veko refrigerator works correctly: signs of normal operation and the first symptoms of malfunctions

Turkish brand refrigerators Veko have long established themselves as reliable and functional devices in the mid-price segment. However, even the highest quality equipment requires proper operation - and for this you need to understand how a working refrigerator should work. Deviations from the norm in noise, temperature or the on/off cycle often signal future breakdowns, which are easier to prevent at an early stage.

In this article we will analyze to the main parameters of normal operation refrigerators Veko (including popular series Veko RCN, Veko RCS and Veko RK), we will explain which sounds and vibrations are considered acceptable and which are not, and also give a checklist for self-diagnosis. We will pay special attention a unique feature of compressors Veko: their operating cycle may differ from European brands due to the climate class SN-T (subtropical), which most models are oriented towards..

If your refrigerator suddenly begins to hum loudly, does not freeze well, or, conversely, freezes “tightly” into the ice, do not rush to call a technician. Perhaps his behavior fits into technical norms that you simply were not aware of. And if not, we will tell you what to pay attention to first.

1. Temperature conditions: what indicators are considered normal

The optimal temperature in the refrigerator Veko depends on the zone and the set mode. The manufacturer recommends the following ranges for most models (unless otherwise stated in the instructions):

• 🥦 Refrigerator compartment: from +2°C to +6°C (ideally +4°C for most products). At temperatures above +6°C, active growth of bacteria begins; below +2°C, freezing of leafy greens and some fruits is possible.
• ❄️ Freezer compartment: from −18°C to −24°C. Mode Super Freeze (if available) briefly lowers the temperature to −30°C for quick freezing.
• 🥛 Freshness zone (0°C): only in models with technology FreshZone (for example, Veko RCN 385220). Maintains temperatures around 0°C for meat, fish and dairy products.

Important: temperature spread across shelves —this is normal! The top of the refrigerator compartment is usually 1-2°C warmer than the bottom (closer to the compressor). To check the accuracy, use external thermometer (not the built-in sensor!) and place it in the center of the middle shelf for 12 o'clock.

⚠️ Attention: If the temperature in the freezer rises above −12°C, and the compressor runs without stopping - this is a sign of a thermostat or a malfunction of the thermostat. data-i="104">Attention: freon leaks or thermostat malfunction. In models Veko with the system No Frost (For example, Veko RCS 514220) this behavior may also indicate icing of the fan.

2. Compressor operating cycle: how long should it work and rest

The refrigerator compressor Veko works cyclically: it turns on for cooling and turns off when it reaches the set value temperature. Normal work coefficient (ratio of work time to rest time) depends on:

• 🌡️ Room temperature (in hot weather the cycle is shortened).
• 📦 Load levels (full refrigerator cools longer).
• 🔄 Operating modes (in Super Cool mode the compressor can operate for up to 2 hours without stopping).

For most models Veko (2018–2026) the following guidelines apply:

• 🔴 Active phase: 15–30 minutes (depending on the compressor power).
• 🟢 Pause: 20–40 minutes (in hot weather it can be reduced to 10–15 minutes).
• ⚠️ Alarm signal: if the compressor runs for more than 1 hour without stopping and the temperature in the chambers does not drop - diagnostics are required.

Models with an inverter compressor (for example, Veko RK 392520) work differently: they do not turn off completely, but reduce the speed. In this case, continuous low hum this is the norm, and not a breakdown. The main thing is that the temperature is kept within the specified limits.

3. Acceptable sounds and vibrations: what should be alarming

Refrigerators Veko are not silent, especially models with a classic (not inverter) compressor. Here normal soundsthat should not cause concern:

• 🔊 Low-frequency hum when the compressor is running (comparable to a quiet rumbling).
• 💨 Air noise in models s No Frost (fan distributes cold).
• 💧 Gurgling or overflowing of liquid - this is freon circulating.
• 🔥 Clicks when the compressor is turned on/off (the starting relay is activated).

And now - sounds that require attention:

• 🚨 Loud knocking or rattling - perhaps the compressor fastenings are loose or the tubes are touching the housing.
• 🌀 Whistling or hissing is a sign of a freon leak (requires urgent repairs!).
• 🔄 Cyclic clicking without starting the compressor - the relay or thermostat is faulty.
• ❄️ Ice cracking in the freezer - a signal about excess icing (defrosting is needed).

⚠️ Attention: If the refrigerator Veko with the system No Frost started to “howl” loudly (high-pitched hum), immediately unplug it! This is a sign of icing of the fan, which can lead to overheating of the motor.

Why is the new Veko refrigerator louder than the old one?

In the first 1-2 weeks of operation, the compressor may make more noise due to the running-in of parts. Also modern models. (for example Veko RCN 385220) are equipped with more powerful fans for uniform cooling, which adds noise. If the sound does not decrease after 2 weeks, check the installation (the refrigerator may be touching furniture or a wall).

4. How to check the tightness and seals of doors

Poor fit of the sealing rubber is one of the most common reasons increased energy consumption and unstable temperature in refrigerators Veko. You can check the tightness in three ways:

1. Test with a sheet of paper: close the door, holding the sheet between the seal and the body. If the sheet is easily pulled out, the elastic is worn out.
2. Visual inspection: the seal should be evenly pressed around the entire perimeter, without cracks or deformations.
3. Condensation on the door: if drops form on the outside - inside the chamber increased humidity due to the suction of warm air.

In models Veko with magnetic seals (for example, Veko RK 392520), the magnet loses strength over time. Service life of the rubber band — 5–7 years, but with active use (frequent opening) it is reduced to 3–4 years. You can replace the seal yourself: original spare parts for Veko sold with article numbers like VEKO-UPL-{model}.

Check with a piece of paper the tightness around the entire perimeter|

Inspect the rubber for cracks and dirt|

Wipe the seal with soapy water (dirt breaks the seal)|

Check the door fastening - it should not sag

-->

⚠️ Attention: If after replacing the seal the door still does not close well, check hinges. In refrigerators Veko with a top freezer (for example, Veko RCS 514220), the hinges sag over time. You can adjust them with a hex key (size 5 mm).

5. Defrosting and care: how often and why it is important

Even refrigerators with system No Frost require periodic defrosting - at least once a year. For models Veko with a drip system (for example, Veko RCN 385220) the recommended interval is every 6 months. Why is this important:

• ❄️ Ice on the back wall impairs heat transfer and makes the compressor work longer.
• 🦠 Mold and bacteria accumulate in the drainage hole, which leads to an unpleasant odor.
• 💡 Energy consumption increases by 15–20% with a thick layer of frost.

Step-by-step instructions for defrosting:

1. Unplug the refrigerator and remove all food.
2. Place a tray to collect water (in models Veko the drainage hole is located at the back, under the bottom shelf).
3. Open the doors and wait for complete defrosting (do not use a hairdryer or hot water!).
4. Rinse the internal surfaces with a soda solution (1 tablespoon per 1 liter of water).
5. Clean the drainage hole with a cotton swab (crumbs often get into it).
6. Wipe dry and turn on the refrigerator. Let it work for 2 hours without food.

⚠️ Attention: In refrigerators Veko s system No Frost (for example, Veko RCS 514220) Do not wash off frost with hot water - this will damage the plastic parts of the ventilation system. Use only warm water (up to +40°C).

6. Energy consumption: how much should a Veko refrigerator eat? Refrigerators belong to the energy consumption class

Refrigerators Veko belong to the energy consumption class A+ or A++ (in new models, the average energy consumption depends on the volume and type). compressor:

If your refrigerator consumes more than normal, check:

• 🔌 Operating mode: in mode Super Cool or Super Freeze consumption increases by 20-30%.
• 🌡️ Room temperature: at +30°C in the room, energy consumption increases by 15–20%.
• 🧊 Ice thickness: a layer of frost 5 mm thick increases consumption by 10%.
• 🚪 Opening frequency: Each opening of the door adds 1-2 minutes of compressor operation.

7. Frequent malfunctions and their first signs

Refrigerators Veko break down less often than European brands due to their simple design, but they also have “weak points.” symptoms: typical malfunctions and their symptoms:

If your refrigerator Veko was manufactured before 2020, pay attention to condenser (the grille at the back In older models, it is often clogged with dust, which leads to overheating). The compressor needs to be cleaned with a soft brush (not metal!) every six months.

How to check the thermostat without a multimeter?

1. Unplug the refrigerator.

2. Remove the thermostat knob (it is usually attached to a latch).

3. Find the two wires going to the thermostat and short them together (for example, with a paper clip).

4. Turn on the refrigerator - if the compressor. has worked, the thermostat is faulty and requires replacement.

⚠️ Be careful: work only with the power off!

Frequently asked questions

Why does the Veko refrigerator get very cold in the refrigerator compartment (food freezes)?

This is a typical problem for models with mechanical thermostat (for example, Veko RCN 385220). Reasons:

• The temperature regulator is set incorrectly (turn it closer to the position 2–3).
• The thermostat is faulty - it “thinks” that the chamber is warmer than it actually is.
• The capillary tube is clogged (freon does not circulate normally).

First try adjusting the temperature. If this does not help, you need to diagnose the thermostat.

The new Veko refrigerator gurgles and clicks loudly - is this normal?

Yes, in the first 1-2 weeks after purchase, such sounds are normal. They are associated with:

• Freon circulation through the system (gurgling).
• Operation of the start relay. (clicking when the compressor is turned on).
• By running in new parts (may be a little louder than later).

If the sounds do not disappear after 2 weeks or become louder, check the compressor mount and installation level.

How to turn on the “Holiday” mode on the refrigerator Veko?

Mode Holiday is present in most models Veko with electronic control (for example, Veko RCS 514220To activate it:

1. Press and hold the button Holiday (or Vacation) 3 seconds.
2. The indicator will light up on the display H or Vacation.
3. The temperature in the refrigerator compartment will rise to +12°C...+15°C, and in the freezer will remain −18°C.

To exit the mode, press and hold the same button again.

Is it possible to place the Veko refrigerator next to the battery?

No, this violates the operating rules Veko requires:

• Distance to heat sources (radiators, stoves, ovens) - no less 50 cm.
• Indoor temperature - no higher than +32°C (for classes SN-T).
• Good ventilation at the back (the gap to the wall is 5–10 cm).

If you place the refrigerator next to the radiator, the compressor will work almost non-stop, which will lead to its premature wear.

What to do if the Veko refrigerator does not turn on after turning off the lights?

Possible causes and solutions:

• The compressor protection has tripped. Wait 10-15 minutes and turn on the refrigerator again.
• The fuse has blown. Check the surge protector (if any) or the socket.
• Failure of the control board. Unplug the refrigerator from the outlet for 1 minute, then turn it on again.
• The relay is faulty. If clicks are heard after turning on, but the compressor does not start, the relay needs to be replaced.

If the refrigerator does not turn on after these manipulations, call a technician.
