Why the TV goes out when the refrigerator is turned off: technical reasons and what do

You turned on your favorite TV series, but as soon as the refrigerator turned off, the TV immediately went out? The situation is annoying and sometimes frightening: it seems that the equipment has “burnt out” or there are electrical problems in the house. In fact, there are several reasons for this behavior - from a banal overload of the outlet to serious faults in the wiring. In this article, we will look at all possible reasonswhy the TV turns off along with the refrigerator, and we will give step-by-step instructionshow to fix it.

It is important to understand: if the problem occurs regularly, it cannot be ignored. Power surges or network overload can lead to equipment breakdowna fire or even an electric shock. We will not scare you with “horror stories” - instead, we will explain how to diagnose yourself fault and when to call an electrician.

Spoiler: in 80% of cases it is not the equipment that is to blame, a improper organization of power supply in the house. But there are exceptions - we’ll tell you about them too.

1. Socket overload: why the TV and refrigerator should not operate from the same extension cord

The most common reason is exceeding the permissible load on the socket or extension cord. Refrigerator and TV, especially modern models, consume a lot of energy. When both devices are connected to the same outlet (or through a tee), when simultaneous start of the refrigerator compressor there is a sharp jump in current. The socket or extension cord may not be able to withstand it - and it triggers automatic shutdown.

How does this manifest itself:

• 🔌 The TV turns off exactly at the moment the refrigerator compressor starts (a characteristic click is heard).
• 🔥 The socket or extension cord plug gets warm (you can check it with your hand).
• ⚡ Other devices in the same socket too “blink” or turn off.

What to do:

• 🔌 Connect the refrigerator and TV to different sockets, preferably on different lines (if the house has several machines in the panel).
• ⚡ Replace the extension cord with a model with overload protection (marked "16A" or "3500W").
• 🛠️ If the socket is old, replace it with a new one with grounding.

⚠️ Attention: Never use cheap Chinese tees without protection - they often cause fires. If you have aluminum wiring in your house (typical of old houses), the risk of overheating increases significantly.

2. Power surges: why the TV “doesn’t like” starting the refrigerator

The refrigerator is one of the few household appliances that creates short-term voltage surgewhen started. In the first seconds of operation, the compressor consumes 3–5 times more current than in normal mode. If the network in the house is unstable, this can lead to:

• 📉 Voltage drop below 190 V (the TV turns off due to protection activation).
• ⚡ A short jump to 250 V (the TV goes into overvoltage protection).
• 🔄 "Blinking" of the screen before turning off.

How to check:

• 🔍 Use voltage tester (multimeter) or network monitor (for example, APC UPS).
• 📊 Record the readings at the moment the refrigerator starts. Normal: 220–230 V ±10%.
• 💡 If the voltage “jumps” more, there is a problem in the network or wiring.

⚠️ Attention: If voltage surges exceed 250 V, it is dangerous not only for equipment, but also for life. In such cases, required install stabilizer or voltage relay for the whole house.

3. walls

If the TV turns off exclusively when the refrigerator is turned off (and not when it starts), the problem may lie in wiringPossible reasons:

• 🔌 Breakage of the neutral wire in the panel or socket (leads to phase imbalance).
• 🔥 Bad contact in the distribution box (sparks, heats up).
• 🛠️ Old aluminum wiringwhich cannot withstand modern loads.

How to diagnose:

1. Unplug the refrigerator from the outlet.
2. Check if the TV is working stably.
3. If yes, connect the refrigerator to another socket (on another wall).
4. If the problem remains, the wiring is to blame; if it disappears, the socket or extension cord.

⚠️ Attention: If when turning off/on refrigerator in the socket is heard crackling or sparks, immediately unplug it and call an electrician. This is a sign short. short circuits in the near future.

What is phase imbalance and why is it dangerous?

Phase imbalance occurs when one phase in the house bears too much load (for example, all powerful appliances are connected to one line). This leads to a voltage drop in this phase and an increase in others. As a result, equipment can fail, and in the worst case, a fire occurs. data-i="166">4. TV protection mechanisms: why is it “afraid” of the refrigerator

4. TV defense mechanisms: why is it “afraid” of the refrigerator

Modern TVs (especially Samsung QLED, LG OLED, Sony Bravia) are equipped with built-in surge protection. voltageIf the network is unstable, the TV can:

• 🔄 Automatically reboot.
• ⚡ Go to protection mode (black screen, indicator flashing).
• 🛑 Completely disconnectif the jump is too strong.

How to fix it:

• 🔧 Go to Settings → Support → Self-diagnosis (path may vary depending depending on the model).
• 📋 Check error log —there may be a fault code (for example, E01 for Samsung means problems with power supply).
• 🔄 Reset the TV settings to factory settings (if the error recurs).

Critical information: If the TV does not turn on at all after turning off (does not respond to the remote control and buttons), this is a sign of a burnt-out power supply. In this case, repairs are required at a service center.

5. Refrigerator malfunctions: when the problem is in the compressor or relay

Sometimes it is not the TV or the wiring that is to blame, but the refrigerator itself. If when it turns off, sharp voltage surgeoccurs, this may be due to:

• 🔧 Faulty start relay compressor (it “sticks” and creates current surges).
• 🛠️ Worn out compressorwhich consumes too much energy when starting.
• ⚡ Breakage to the housing (life-threatening!).

How to check:

• 🔊 Listen to the operation of the refrigerator: if the compressor hums too loud or clicks at startup, this is a sign of a malfunction.
• 💡 Check to see if the refrigerator body is shocking (touch it carefully with the back of your hand).
• 📊 Use current clamps (if any) to measure the inrush current. Norm: no more 10–12 A for household models.

⚠️ Attention: If the refrigerator electric shock or it smells burning, immediately disconnect it from the network and call a technician. Operating such a device is dangerous!

6. External factors: why the problem may not be in the equipment

Sometimes the TV turns off when the refrigerator is turned off for reasons not directly related to electricity:

• 🌩️ Thunderstorm or unstable weather —lightning can cause impulse noise in the network.
• 🏗️ Construction work nearby — welding machines or hammer drills create voltage surges.
• 🔌 Neighbors connected a powerful device (for example, an air conditioner or heater) to the same phase.

What to do:

• 📅 Keep outage diary: record time and circumstances (weather, working devices at neighbors).
• 🔌 Install surge protector with protection against impulse interference (for example, Pilot Pro or APC SurgeArrest).
• 📞 Contact management companyif the problem is widespread (neighbors also complain).

7. What to do if nothing helps: step-by-step action plan

If you have tried everything, but the TV still turns off when the refrigerator is turned off, follow this. algorithm:

1. Step 1. Isolate the problem
   • Disconnect the refrigerator from the network.
   • Check whether the TV works stably without it.
   • Connect the refrigerator to another outlet (in another room) - is the problem still there?
2. Step 2. Check the power quality
   • Use voltage tester to measure network parameters.
   • If the voltage is outside the limits 190–240 V, install stabilizer.
3. Step 3. Diagnose the equipment
   • Check TV error log (in the support menu).
   • Inspect plug and refrigerator cord for melting.

Step 4. Contact a specialist

• If the problem is in the wiring, call electrical.
• If in the refrigerator - repair experts.
• If on the TV - service center.

⚠️ Attention: Do not try to repair the refrigerator or TV yourself if you do not have experience. Errors when working with compressor. data-i="274">power supply unit or power supply can lead to irreversible damage or electric shock.

How much does the repair cost?

The cost of diagnosing a refrigerator is from 1500 ₽, replacing the start relay - from 2500 ₽. Repair of the TV power supply - from. 3000 ₽. Installation of a voltage stabilizer at home - from 5000 ₽ (excluding the cost of the device).

FAQ: Frequently asked questions about turning off the TV together with the refrigerator

Can the TV burn out due to power surges from the refrigerator?

Yes, if surges exceed 250 V or occur regularly. Modern TVs have protection, but it does not always work on time. To avoid breakdown, use surge filter or voltage stabilizer.

Why does the problem appear only at night?

Most likely, at night additional loads are turned on in your house or at the substation (for example, heaters from neighbors or street lighting). This leads to a voltage drop. The solution is to install voltage relay, which will turn off the equipment when leaving. parameters are beyond acceptable limits.

The refrigerator is new, but the TV is old - what's the matter?

Probably, the new refrigerator has a more powerful compressor, which creates a larger starting current. Old TVs (especially those with CRT) are more sensitive. to power surges. Try to connect the TV through uninterruptible power supply (UPS).

Is it possible to use one extension cord for the refrigerator and TV?

It is strictly not recommended. energy-intensive devices in the house. Connecting them together to one extension cord leads to overheating of contacts and the risk of fire. Use separate sockets with grounding.

After a power surge, what should you do?

Turn it off first. from the network for 10-15 minutes - the protection may have worked. If it does not help:

1. Check the fuse in the plug (if any).
2. Try to plug the TV into another outlet.
3. If the screen remains black, contact a service center (the unit is probably burned out supply).
