You approached the refrigerator Samsung, and it shows no signs of life: the light inside does not light up, you cannot hear the characteristic hum of the compressor, and the display (if there is one) shows blankness or flashing errors. The situation is familiar to many owners of equipment from this brand, especially after power surges, prolonged downtime or moving. But before you panic and call a technician, it’s worth figuring out: perhaps the problem can be solved in 5 minutes without disassembling the case.
In this article we will consider all possible reasonsreasons why the refrigerator Samsung may not turn on - from trivial (the machine in the panel was knocked out) to serious (the starting capacitor or compressor burned out). For each malfunction, we will provide step-by-step instructions diagnosis information, and also indicate where you can do it yourself, and where you cannot do without professional repairs. We will pay special attention to models with system No Frost and inverter compressors, which have their own “weak points.”
If your refrigerator Samsung not only does not cool, a completely does not respond to switching on (no sounds, lights, indications), start by checking the power and network cable. In 30% of cases the problem lies here. The remaining 70% is distributed between electronics, compressor and thermostat faults. Below is a detailed analysis of each of them.
1. Checking the power: socket, plug, cable
The first thing you need to do is make sure that the refrigerator Samsung generally receives electricity. This may seem obvious, but often users miss basic things. Start with inspection network cable: it must be intact, without kinks, melts or traces of rodents (if the refrigerator is in a private house or in the country).
Next check:
- 🔌 Socket: connect another device to it (for example, charging a phone or table lamp). If it does not work, the problem is in the socket or circuit breaker in the panel.
- ⚡ Circuit breaker: the circuit breaker in the electrical panel could have tripped (especially if the refrigerator is connected via an RCD). Try turning it on again.
- 🔧 Plug and cable: inspect the plug contacts for oxidation or burning. If you have a multimeter, check the integrity of the cable in the “continuity” mode.
If the refrigerator Samsung is connected via surge protector or extension cord, try plugging it directly into the outlet. Cheap filters often cannot withstand the starting currents of the compressor and turn off. Also pay attention to on/off button (if your model has it) - sometimes it is accidentally pressed when rearranging equipment.
2. Display and indication: what do flashing errors mean? If the screen flashes, shows an alphanumeric code, or does not turn on at all, this is a clue to diagnosis. Below is a breakdown of the most common errors:
Modern refrigerators Samsung (series RB, RF, RS**) are equipped with electronic displays that display faults Error codes. If the screen flashes, shows an alphanumeric code, or does not turn on at all, this is a clue to diagnosis. Below is a breakdown of the most common errors:
| Error code | Description of the problem | Possible causes | Recommendations |
|---|---|---|---|
E1 or 1E |
Error in the refrigerator compartment temperature sensor | Faulty sensor, broken wire, oxidation of contacts | Check the connection of the sensor to the control board |
E2 or 2E |
Freezer sensor error | Similar to E1, but for the freezer | Similarly, if repeated - replace the sensor |
E3 or 3E |
Problem with the environmental sensor | The sensor is dusty or faulty | Clean the sensor, check the circuit |
E4 or 4E |
Malfunction of the defrosting system (No Frost) | The defrosting heating element is burnt out, the timer or fusible is faulty fuse | Master diagnostics required |
E5 or 5E |
Fan error | Frozen blades, faulty fan motor | Defreeze the refrigerator by 12 hours |
If the display Samsung does not turn on at all, but the refrigerator hums or the relay clicks, the problem may be in control board or the power supply. In this case:
- Disconnect the refrigerator from the mains for 10 minutes, then turn it on again (sometimes a reset helps).
- Check the voltage in the socket with a multimeter - it should be
220–240 Q. - If after turning on the display blinks and goes out, this is a sign of a board malfunction.
What to do if the display shows "OF OF"
This inscription means that the refrigerator has switched to demonstration mode (like in a store). To exit it, simultaneously press the Power Cool and Power Freeze buttons for 5-10 seconds. If it doesn’t help, unplug the refrigerator for 1 minute.
3. Start relay and compressor: why the refrigerator clicks but does not start
One of the most common reasons why the refrigerator Samsung does not turn on, but at the same time clicks are heard is a malfunction start relay or itself compressor. Clicking sounds indicate that the relay is trying to start the compressor, but it does not “catch.” Here's how to diagnose it:
- 🔧 Compressor relay: contacts often burn out or the coil fails. To check, remove the relay (it is attached to the compressor) and inspect the contacts for carbon deposits. If you have a multimeter, check the winding resistance (should be within
20–50 Ohm). - ⚙️ Compressor: if the relay is working properly, but the compressor does not start, it may be jammed or the winding is burnt out. Check the resistance between the compressor terminals (between
C-S,C-R,S-R).Normal values:C-S ≈ 20 Ohm,C-R ≈ 15 Ohm,S-R ≈ 30 Ohm.
If the compressor hums, but does not start, and the relay is hot, this is a sign turn-to-turn short circuit in the compressor windingIn this case, the compressor will need to be replaced, since it cannot be repaired. Please note: in refrigerators Samsung with inverter compressors. (series Digital Inverter) the relay is often built into the control board, and its replacement requires soldering.
☑️ Compressor diagnostics
4. Thermostat and control board: hidden faults
If the refrigerator Samsung does not turn on, but the light inside is on and the compressor is silent, the problem may lie in thermostat (in mechanical models) or control board (in electronic models). Here's how to check them:
Thermostat (installed in models without a display, for example, Samsung RL-33**):
- 🔍 Find the thermostat - it is usually located inside refrigerator compartment, behind the plastic panel.
- 📊 Check it with a multimeter: in the "maximum" position the resistance should be
0 Ohm(contacts closed), in the "off" position -∞(open). - 🔧 If the thermostat does not click when you turn the knob, it is faulty and must be replaced.
Control board (in models with a display, for example, Samsung RB-37 J5240):
- 🕳️ Inspect the board for the presence of swollen capacitors, burnt tracks or traces of moisture.
- 🔌 Check the voltage at the input of the board (should be
12 Vor5 Vdepending on the model). - 🔄 Try resetting the board by turning off the refrigerator for 10 minutes.
A common problem with the boards Samsung — triac failureIf you do not understand electronics, it is better to entrust the repair of the board to a specialist. Soldering it yourself without experience can lead to complete failure of the module. building.
5. No Frost system: why the refrigerator does not turn on after defrosting
Refrigerators Samsung with the system No Frost (for example, models Samsung RL-44, RS-552) have additional components that can block switching on after defrosting or a power outage. Main reasons:
- ❄️ Frozen. fan: if there is water left after defrosting, it could freeze on the fan blades, blocking its rotation. The refrigerator will not turn on until the fan starts working.
- 🔥 The defrosting heating element has burned out: if the heater that melts the frost is burned out, the system No Frost blocks the start of the compressor.
- ⏱️ The defrost timer is faulty: if the timer is stuck in the “defrost” position, the compressor will not will start.
To fix the problem:
- Unplug the refrigerator for 12-24 hours so that the ice completely melts.
- Check the fan rotation manually - it should easily scroll.
- Test the defrosting heating element with a multimeter (the resistance should be
20–60 Ohm).
If after defrosting the refrigerator Samsung turns on, but after a few hours it turns off again and does not start - this is a sign malfunction defrost sensor or fuse (it burns out when the heating element overheats).
6. Additional reasons: from the door switch to the firmware
Sometimes the refrigerator Samsung does not turn on for less obvious reasons. more details:
- 🚪 Faulty door switch: if the switch that turns on the light when the door is opened is stuck in the “door open” position, the refrigerator may block the compressor from starting. Check if the light goes out when the door is closed.
- 🔄 Firmware failure: in “smart” models Samsung Family Hub (for example RF23J9011), software failures are possible. Try resetting the settings to factory settings through the menu or by turning off the power for 1 minute.
- 🌡️ Condenser overheating: if the refrigerator is located close to the wall or battery, the capacitor (grid at the back) overheats, and thermal protection turns off the compressor. Provide a gap of at least
5 cm.
It is also worth checking surge filter (if it is built into the refrigerator plug In models). data-i="226">it often fails after power surges. To check, connect the refrigerator directly to the outlet, bypassing the filter. Samsung it often fails after power surges. To check, plug the refrigerator directly into the outlet, bypassing the filter.
How to reset a Samsung refrigerator to factory settings
In most models, this requires simultaneously pressing and holding the buttons Power Cool i Fridge within 5-8 seconds. After resetting, all settings (temperature, modes) will return to standard.
7. When to call a service technician: signs of serious breakdowns
Not all faults can be fixed on your own. center:
- ⚡ Short circuit in the compressor: if, when you turn on the refrigerator, the machine in the panel knocks out or you smell a burning smell.
- 💻 Failure of the control board: if the display flashes, shows errors that are not reset, or the refrigerator turns on and immediately turns off.
- ❄️ Freon leakage: if the compressor is running, but the refrigerator does not cool, and oil stains are visible on the back wall.
- 🔧 Mechanical damage: cracks in the tubes, deformation of the case after a fall.
The cost of repair depends on the model and type of fault. For example, replacing a compressor in a refrigerator Samsung RL-34 will cost 8 000–12 000 ₽, and repairing the control board will cost 3 000–6 000 ₽Before the technician’s visit. mandatory:
- Write down the model of the refrigerator (located on the sticker inside or on the back).
- Take a photo of the error codes (if any).
- Describe the symptoms in as much detail as possible (when the problem appeared, what preceded it).
8. Prevention: how to avoid breakdowns in the future
To ensure that the refrigerator serves for a long time and does not refuse to turn on, follow these simple steps. rules: Samsung served for a long time and did not refuse to turn on, follow simple rules:
- 🔌 Use voltage stabilizerif your network has frequent surges. Refrigerators Samsung are sensitive to changes, especially models with electronic control.
- ❄️ Defrost the refrigerator at least once a year (even if it has No Frost). This will prevent ice from accumulating on the fan and heating element.
- 🧹 Regularly clean condenser (grid at the back) from dust. A dirty condenser leads to overheating and thermal protection.
- 🚫 Do not place the refrigerator next to stove, radiator or windowwhere it is exposed to direct sunlight rays.
Also avoid:
- 🔌 Frequently turning on/off the refrigerator (the interval between starts should be at least
5–10 minutes). - ❄️ Storing hot foods (this increases the load on the compressor).
- 🧊 Using sharp objects to remove ice (the evaporator can be damaged).
If you are leaving for a long time (for example, to the country in winter), do not leave the refrigerator Samsung turned on in an empty room. Turn it off, wash it, leave the door ajar, and put a moisture absorber inside.
FAQ: Frequently asked questions about malfunctions of Samsung refrigerators
The Samsung refrigerator clicks, but does not start. What could it be?
Clicks indicate. response starting relay, which tries to start the compressor. Reasons:
- The relay is faulty (needs to be replaced).
- The compressor is jammed or burned out (diagnostics required).
- Low voltage in the network (check with a multimeter).
If clicks are repeated every 5-10 seconds, this is a sign turn-to-turn short circuit in the compressor.
After turning off the light, the Samsung refrigerator stopped working turn on. What to do?
First check:
- If the machine in the control panel has tripped.
- The integrity of the network cable and plug.
- Is there an error code on the display (for example,
E4- problem with the system No Frost).
If everything is in order, but the refrigerator does not turn on, it is possible that the varistor (overvoltage protection) has burned out or the control board has failed.
Samsung refrigerator turns on for 5 seconds and turns off. What's the matter?
This is a typical symptom:
- Failure of the control board (the triac that controls the compressor often fails).
- Overheating of the compressor (thermal protection is activated).
- Short circuits in the compressor winding (need replacement).
If the refrigerator is new - possible defective compressor. Contact the service center under warranty.
The display of the Samsung refrigerator shows “OF OF”. How to remove it?
This is demonstration modewhich is included in stores. To exit:
- Press and hold the
Power CoolandPower Freezebuttons simultaneously for 5-10 seconds. - If that doesn’t help, unplug the refrigerator for 1 minute.
If the message appears again, the button or control board is faulty.
Is it possible to replace the compressor in a Samsung refrigerator yourself?
Theoretically yes, but in practice it is a complex and dangerous process:
- Required special equipment to vacuum the system and refill freon.
- You need to accurately select the compressor model (they differ in power and type of freon).
- If you make mistakes, you can cause damage capillary tube or evaporator.
If you do not have experience, it is better to entrust the replacement to a professional. Cost of work: 5 000–8 000 ₽ + compressor price.
