You turned on the refrigerator, and at the same moment the TV suddenly turned off? The situation is unpleasant, especially if it happens regularly. Such a problem can indicate either a banal overload of the outlet or serious malfunctions in the electrical wiring or the equipment itself. In this article we will look at all possible reasonswhy the TV turns off when the refrigerator starts, and we will give step-by-step instructionshow to fix it - from simple checks to complex diagnostics.
Important understand that ignoring the problem is fraught not only with discomfort, but also damage to equipment or even fire due to overheating of the wires. Don’t rush to blame the refrigerator or TV - the electrical network is often to blame. Let's start with the simplest and gradually move on to complex cases.
1. Overloading an outlet or extension cord
The most common reason is exceeding the permissible load per socket or extension cord. The refrigerator, especially when starting the compressor, consumes more 3–5 times more energythan in normal mode. If a TV, microwave or other equipment is connected to the same outlet, the protection is triggered.
How to check this?
- 🔌 Calculate the total power connected devices. When starting, the refrigerator can take up to
1500–2000 W, TV -100–300 W. If the amount exceeds2200 W(for a standard outlet), the problem is overload. - 🔍 Inspect the extension cord: if it is thin, with damaged insulation or designed for
10A (2.2 kW), it needs to be replaced. - ⚡ Try connecting the TV to a different outlet - if the problem disappears, overload is to blame.
The solution is simple: share the load. The refrigerator should be powered from a separate outlet, and the TV from a different line. If there are not enough sockets, install power filter with overload protection or extend a new line.
2. Faulty wiring or circuit breaker
If the TV turns off only when starting the refrigerator, and not during its operation, the problem may lie in poor contact or worn wiring. When starting the compressor, a short-term surge currentoccurs, which leads to a voltage drop or tripping of the protection.
Signs of wiring malfunction:
- 💡 Flickering of light when the refrigerator is turned on.
- 🔥 Foreign odors (burnt plastic or rubber) sockets.
- 🔌 Heating of the plug or socket after operation of the refrigerator.
- ⚡ Frequent operation of the machine in the panel for no apparent reason.
What to do?
- Disconnect the refrigerator and TV from the network.
- Check
automatic switchin the panel: if it is older than 10 years or is designed for10Areplace it with16A. - Inspect the socket: melted contacts or blackened wires - a signal for replacement.
- If you do not have the skills to work with electricity, call an electrician to check cable cross-section i contact quality.
3. Power surges in the network
Refrigerators with inverter compressors (for example, LG Inverter Linear or Samsung Digital Inverter) create pulse loadat startup, which can cause a voltage sag. If your network already has unstable voltage (lower 200V or higher 240V), the TV, especially with LED backlight, may turn off.
How to check?
- 📊 Buy multimeter or voltage recorder (for example, Elitech SP 301) and measure the voltage in the socket when starting the refrigerator.
- 💡 If the voltage drops below
190Vor rises above250V, the problem is in the network. - 🔌 Check whether the voltage indicator on stabilizer (if any) is blinking.
Solutions:
- 🛡️ Install voltage stabilizer for TV (with a power of
500 W). - 🔧 If the problem is in the refrigerator, connect it through surge protector with surge noise protection.
- 📞 Contact the management company - perhaps the problem is in the transformer substation.
What is an inverter compressor?
Inverter compressors smoothly regulate power, but when starting up they can create short-term peak loads of up to 2-3 kW. This is more economical than conventional compressors, but is more sensitive to quality. network.
4. Malfunction of the refrigerator starting relay
If the TV turns off precisely at the moment the compressor startsand not during its operation, it may be to blame starting relayIt is responsible for starting the engine, and if it malfunctions short circuits or jumps currentthat affect other devices.
Signs of a faulty relay:
- ❄️ Refrigerator does not freeze or does it intermittently.
- 🔊 You can hear clicking from the back of the refrigerator when you try to start.
- ⚡ The TV turns off only on the first start after inactivity.
How to check?
- Unplug the refrigerator.
- Remove the back cover (if the model allows it).
- Find starting relay (usually a black box next to the compressor).
- Check it for melts, cracks or burning smell.
If the relay is faulty, it must be replaced. For models Atlant, Indesit or Beko universal relays like DANFOSS 103N0012 or Emerson 210-1056are suitable. For the exact model, check the brand of the relay on the label on the compressor.
☑️ Diagnostics of the starting relay
5. Problems with the TV power supply
Sometimes it is not the refrigerator that is to blame, but TV power supply. If it is worn out or not designed for power surges, then when the refrigerator starts, the protection may be triggered. This is especially true for old TVs with CRT or cheap LED models without stabilization.
How to determine?
- 🔌 Connect the TV to another outlet (for example, in another room). If the problem remains, the power supply is to blame.
- 💡 Look at power indicator: if it blinks or goes out when you start the refrigerator, the unit cannot cope with the load.
- 🔊 Listen: if from the TV are heard squeaking or crackling at the moment of shutdown, this is a sign of a malfunction of the capacitors in the unit.
Solutions:
- 🔧 Take the TV to a service center to check capacitors i diode bridge in the power supply.
- 🛡️ Connect the TV via UPS (uninterruptible power supply) - this will protect against surges.
- 🆕 If the TV is older than 10 years, consider replacing it - modern models are less sensitive to voltage surges.
6. Incorrect grounding or absence of an RCD
In old houses it is often missing grounding, and in new ones it may be done incorrectly. When the refrigerator starts, this leads to current leakageto which the RCD (residual current device) or the TV power supply reacts. If there is no RCD, surges can damage the equipment.
How to check the grounding?
- 🔌 The socket should have three wires: phase, neutral and ground (yellow-green).
- 📊 Use socket tester (for example, Kewtech KT63) - it will show whether the grounding is connected correctly.
- ⚡ If you feel tinglingwhen you touch the body of the refrigerator or TV, this is a sign of a leak.
Solutions:
- 🔧 Install RCD on the refrigerator line (leakage current
30 mA). - 🏠 If there is no grounding, contact an electrician to organize it (in a private house) or install potential equalization systems (in an apartment).
- ⚠️ Never connect grounding to pipes or batteries! This is life-threatening.
7. The influence of other household appliances
Sometimes the problem is not in the refrigerator, but in other equipmentconnected to the same line. For example, washing machine, air conditioner or microwave can create interference, which is added to the surge from the refrigerator and leads to the TV turning off.
How to identify the culprit?
- 🔌 Turn off one by one all appliances from the network, leaving only the refrigerator and TV.
- 📊 If the problem disappears after turning off a device, it is causing interference.
- 💡 Pay attention to induction cookers i welding machines —they greatly influence the network.
Solutions:
- 🔧 Redistribute devices among different sockets and machines.
- 🛡️ Use interference filters for sensitive equipment.
- 📊 Install multi-tariff counter with the power quality analysis function.
What to do if nothing helps?
If you have tried all the methods, but the TV still turns off when you start the refrigerator, it’s time to contact a specialist. Here is a checklist for a visit to the technician:
☑️ Preparation for an electrician's visit
Possible deep reasons:
| Cause | Symptoms | Solution |
|---|---|---|
| Faulty refrigerator compressor | The refrigerator hums, but does not freeze; the TV turns off every time it starts | Replacing the compressor or refrigerator |
| Poor insulation of the wiring in the wall | Smell of burning, sockets get hot, the machine switches off without load | Replacement of wiring (full or partial) |
| Incompatibility of equipment with the network | The problem appears only with certain models of refrigerators/TVs | Installing a stabilizer or UPS |
| Problems in the transformer substation | Power surges in all neighbors, flickering lights in the evenings | Collective appeal to energy sales |
Critical information: If the TV turns off with a characteristic click and does not turn on again until it is completely disconnected from the network, this is a sign that the overvoltage protection has tripped. In this case, DO NOT turn it on again without diagnostics - this may lead to damage to the motherboard!
FAQ: Frequently asked questions
Can the TV break due to constant shutdowns when starting the refrigerator?
Yes, if shutdowns occur due to voltage surgesit can damage the power supply, motherboard or LED backlight TV models. with thin wires in the power supply (for example, cheap Chinese LED-TV).
To avoid breakdowns, use a surge protector with surge protection or UPS.
Why did the problem appear suddenly, although everything worked fine before?
Probable reasons:
- 🔌 Wear of wiring —over time, the contacts oxidize and the resistance increases.
- ⚡ Deterioration in power quality in the network (for example, after connecting new consumers in the house).
- 🛠️ Faulty refrigerator compressor —over time, it begins to consume more current when starting up.
- 📺 Failure of capacitors in the TV power supply.
Start with a check sockets and extension cords - often the problem lies in them.
Is it possible to connect a refrigerator and TV through one extension cord with a filter?
Technically it is possible, but only if:
- 🔌 The extension cord is designed for
16A (3.5 kW)and has overload protection. - 🛡️ It has varistors (protection against power surges).
- ⚡ The total power of the refrigerator and TV does not exceed
2.5 kW.
However the best option — connect them to different outlets, especially if the refrigerator has an inverter compressor.
Which voltage stabilizer should I choose for my TV?
The following models are suitable to protect the TV from surges:
| Model | Power | Suitable for | Price (approximately) |
|---|---|---|---|
| Resanta ACH-500/1-C | 500 W |
LED TVs up to 43" | 2 500 ₽ |
| Energy Classic 1000 | 1000 W |
TVs 50–65" and receivers | 5 000 ₽ |
| Calm R 600ST | 600 W |
For sensitive equipment (OLED, QLED) | 7 000 ₽ |
For a refrigerator, it is better to choose a separate stabilizer with a power of 2000 W (for example, Resanta ACH-2000/1-C).
What what to do if the problem occurs only at night?
Night shutdowns of the TV when starting the refrigerator are often associated with:
- ⚡ Drop in voltage in the network due to increased load (neighbors turn on heaters, air conditioners).
- 🌡️ Operation of the refrigerator in intensive freezing mode (at night the temperature in the room is lower, and the compressor turns on more often).
- 🔌 Faulty night tariff meter (interference occurs in some models).
Solution: install voltage relay (for example, Zubr D63t) or connect the TV via UPS.
If after reading the article you still have not found the reason, contact an electrician with network analysis equipment (for example fluke analyzer). In 90% of cases, the problem is solved by replacing the socket, installing a stabilizer or redistributing the load. Do not delay diagnostics - this will save your equipment from serious damage!
