You turned on the refrigerator VEKO, heard the characteristic click of the relay, the motor hummed for 1-2 seconds - and immediately everything went quiet? This problem occurs in models VEKO RKN-2050, VEKO RKN-220 and other series, especially after 5-7 years of operation. In 80% of cases, only 3 components are to blame: the start-up relay, the compressor or the electronic control unit. But there are also less obvious reasons that are not written about in standard instructions.
This article is an analysis of all possible faults with step-by-step diagnostics, which does not require professional equipment. You will learn how to distinguish a burnt-out relay from a jammed compressor, why a refrigerator can “blink” during voltage surges, and when to call a repairman. And also - a list of VEKO models with a factory defective thermostat (2018-2020 production), which were recalled under warranty.
1. Start-up relay: why it clicks and turns off the refrigerator
The most common reason for a “short start” is a malfunction start-protection relay. This small unit (usually black or gray, attached to the compressor) performs two functions: it starts the motor and protects it from overheating. If the relay fails, the compressor does not receive enough voltage for stable operation and turns off after 1-5 seconds.
How to check the relay yourself:
- 🔊 Listen for clicks. A healthy relay makes one clear click when starting. If you hear multiple clicks in a row, this is a sign of “sticking” contacts.
- 🔧 Remove the relay (disconnect the terminals and unscrew the screws) and shake. Will there be a rattling sound? This means that the magnetic core inside has broken off.
- 📏 Check the resistance with a multimeter. Between the contacts
3-4(winding) there should be 10-30 Ohms, between1-2(motor contacts) - 0 Ohms.
In models VEKO RKN-240W i VEKO RKN-260 a relay defect is often found Danfoss 103N0012 - its spring loses its elasticity after 3-4 years of operation. Replacing with an analog StartCap 103R0052 solves the problem for 5+ years.
⚠️ Attention: If the relay gets very hot (you can get burned), you should not touch it with your bare hands - use insulated pliers handles. Overheating indicates a short circuit in the compressor winding.
2. Compressor: jamming, interturn short circuit or wear
If the relay is working properly, but the refrigerator VEKO still turns off after a couple of seconds, the problem is compressor. Three-dimensional scenario:
- Shaft jamming —the motor cannot turn due to lack of oil or metal shavings.
- Interturn short circuit —the windings close together, triggering the protection.
- Wear of the piston group —the compressor starts, but does not create the required pressure and turns off.
Compressor diagnostics:
- 🔧 Check the shaft: turn off the refrigerator, remove relay and try turning the compressor shaft with a screwdriver through the technological hole. If it does not rotate, it is jammed.
- 📊 Measure the resistance of the windings:
- Between
C-S(common and starting winding): 20-40 Ohms. - Between
C-R(common and working): 10-20 Ohm. - Between
S-R(starting and working): the sum of the two previous values.
Deviation by more than 30%? This means that the windings are damaged.
- Between
In models VEKO RKN-185 and VEKO RKN-210 compressors are often defective Embraco EGX 90H —their windings overheat due to thin insulation. If the resistance between the housing and the contacts is less than 1 MOhm, the compressor is “broken” and must be replaced.
How to check the compressor without a multimeter?
If there is no multimeter, turn on the refrigerator and put your hand on the compressor housing. A healthy motor vibrates evenly and heats up to 50-60°C. If the case is cold, but the relay clicks, the compressor does not start. If the housing is hot (more than 70°C), but the motor does not hum, there is an interturn short circuit.
3. Thermostat or electronic control unit: hidden faults
In refrigerators VEKO s mechanical thermostat (models before 2019), the problem may lie in its incorrect operation. If the thermostat is stuck in the off position, the compressor will be commanded to stop immediately after starting. In electronic models (VEKO RKN-245W, VEKO RKN-280), a firmware failure or failure of the triac in the control unit may be to blame.
Signs of a thermostat/electronics malfunction:
- 🔄 The refrigerator turns on and turns off at intervals of exactly 1-2 minutes (cyclically).
- 📉 The temperature in the chamber does not correspond to the set one (for example, +15°C at the set +5°C).
- 💡 All indicators are flashing on the control panel or an error is on
E1/E2.
How to check thermostat:
- Remove the thermostat knob and find two wires going to it.
- Close them together (for example, with a paper clip). If the refrigerator starts and works without stopping, the thermostat is faulty.
In electronic models, resetting the settings to factory settings (hold "Mode" + "Temp" button for 10 seconds) helps in 40% of cases. If not, flashing or replacement of the board is required.
| VEKO model | Control type | Frequent malfunction | Repair method |
|---|---|---|---|
| VEKO RKN-2050 | Mechanical thermostat | Sticking thermostat contacts | Replacing the thermostat K59-L1433 |
| VEKO RKN-240W | Electronic unit | Firmware failure (error E3) |
Flashing or replacing the board |
| VEKO RKN-185 | Mechanical | Breakage of the thermostat capillary tube | Replacing the thermostat + refilling with freon |
| VEKO RKN-280 | Electronic | Failure of the compressor triac | Replacement of the triac BTA16-600B |
4. Problems with power supply: why is the VEKO refrigerator sensitive to voltage
Refrigerators VEKO (especially models with inverter compressors) react sharply to power surges. If your network often has less than 190V or more than 240V, the start-up relay may falsely operate, thinking that the compressor is overloaded. Also, the problem may lie in:
- 🔌 Faulty socket — oxidized contacts create additional resistance.
- 🔋 Weak network filter —if the refrigerator is connected through an extension cord with thin wires.
- ⚡ Lack of grounding —leads to interference in the electronic unit.
How to check the power:
- Connect the refrigerator directly to the outlet (without extension cords).
- Use voltage stabilizer (for example, Resanta ASN-1000) and observe the operation for 2-3 hours.
- Check the voltage with a multimeter when the compressor starts. If it drops below 180V, there is a problem in the network.
⚠️ Attention: Never connect a refrigerator VEKO with an inverter compressor through a UPS (uninterruptible power supply) with a modified sine wave. This leads to overheating of the windings!
5. Freon leak or clogged capillary tube
If the refrigerator VEKO turns on for 1-2 seconds and then turns off with a pause of 5-10 minutes, it is possible freon leak or clogging in the capillary system. In this case, the compressor cannot create the required pressure and current protection is triggered.
Signs of leakage/clogging:
- ❄️ The freezer does not it’s freezing, but the light inside is on.
- 🔊 The compressor hums louder than usual, as if it’s “straining.”
- 🕳️ Oil stains are visible on the back wall of the refrigerator (a sign of a microcrack in the circuit).
Independent diagnostics:
- Turn off the refrigerator and defrost it for 12 hours.
- Turn it on again. If the compressor starts and runs for more than 10 seconds, there is a blockage in the capillary tube. If not, there is a freon leak.
In models VEKO RKN-220 i VEKO RKN-260 it often becomes clogged filter drier (the white cylinder on the compressor tube). Replacing it together with refilling freon (R134a or R600a, look on the nameplate) solves the problem.
Do not turn on the refrigerator for more than 5 minutes|Check the back wall for oil stains|Remove food and defrost for 12 hours|Call a technician with refueling equipment

6. Additional reasons: from a capacitor to a manufacturing defect
If all of the above components are working properly, check:
- 🔋 Start capacitor (if present in the model). Swelling or electrolyte leakage is a sign of a malfunction. Normal capacitance: 15-40 µF (checked with a multimeter in the
Cx). - 🧲 Sensor temperature mode (in electronic models). If it is lying, the control unit gives a false shutdown command. It is checked by replacing it with a known good one.
- 🏭 Factory. defect. In batches VEKO 2018-2020, there were compressors with defective valves (EGX 70/80H series) They could work for 1-2 years and then start shutting down after 1-3 seconds.
In models VEKO RKN-200 i VEKO RKN-215 sometimes it fails evaporator fanIf it is blocked by ice or burned out, the electronic unit “thinks” that the system. overheated and turns off the compressor.
7. When to call a technician: 3. cases when amateur activity is dangerous
Some malfunctions require professional equipment and experience. Contact the service center if:
- 🔧 Required refilling freon - this cannot be done without a vacuum pump and a leak detector.
- ⚡ Required compressor replacement —a soldering station and skills in working with refrigerant are required.
- 🔄 Required reflashing the electronic unit —without original software and adapter can “kill” the board completely.

FAQ: Frequently asked questions about malfunctions of VEKO refrigerators
My VEKO RKN-240W refrigerator turns on for 2 seconds and turns off. The relay clicks, but the motor does not start. What should I do?
Rather. total the compressor is jammed or its winding has burned out. Check:
- The resistance of the windings (should be 10-40 Ohms). If “infinity” is an open circuit, if 0 is a short circuit.
- Is it possible to rotate the compressor shaft manually (through the technological hole). If not, it is jammed.
In 90% of cases, the compressor needs to be replaced. Models VEKO RKN-240W often installed motors Embraco EGX 90Hthat are sensitive to voltage changes.
The VEKO refrigerator turns on and immediately turns off, and the display shows error E1. What does this mean?
Error E1 in refrigerators VEKO indicates problem with the temperature sensor or an open circuit. Try:
- Turn off the refrigerator for 10 minutes, then turn it on again (sometimes resetting the error helps).
- Check the wires going from the sensor to the control board (they may be chafed or oxidized).
- Replace the sensor with a known good one (for example, NTC 10kOhm).
If the error remains, the control board is faulty.
After moving, the VEKO refrigerator began to turn off after 3 seconds. What's wrong?
Most likely, during transportation:
- 🔌 The contacts of the start-up relay or compressor have come loose (check the tightness of the connections).
- 💧 The capillary tube of the thermostat is damaged (if the model is mechanically controlled).
- 🧲 The temperature sensor has moved (in electronic models).
Turn off the refrigerator for 12 hours, then turn it on. If the problem remains, check the relay and the compressor.
Is it possible to replace the start-up relay on a VEKO refrigerator yourself?
Yes, this is one of the easiest operations for you. you will need:
- Phillips screwdriver.
- New relay (suitable for your compressor model).
- Multimeter (optional, for checking contacts).
Algorithm:
- Disconnect the refrigerator from the network.
- Remove the relay cover (usually secured with 1-2 screws).
- Take a photo of the wire connections, then disconnect them.
