Why the Bosch refrigerator turned off: reasons and solutions (2026)

You opened the refrigerator door Bosch, and inside it is warm, the light does not light, and the unit is silent like a fish on ice. Is the situation familiar? A sudden refrigerator shutdown is one of the most stressful breakdowns: food spoils, and the reasons are not always obvious. But don’t panic: in 70% of cases, the problem can be solved on your own without calling a technician.

In this article we will look at why your all possible reasonsaccording to which your Bosch (be it a model KGE39AW20R, KGN39VL35 or another from the line) could turn off - from the banal (the traffic jams were knocked out) to serious (compressor burned out). You will learn how to diagnose the problem by external signswhat manipulations are safe to carry out with your own hands, and when it is better to immediately call the service center. We will pay special attention hidden "chips" Boschto which are not written in standard instructions - for example, how to reset an error E:24 without losing the warranty.

1. Let's check the obvious: power supply and network problems

The first thing to do is to rule out electrical problems. Even if “everything works” in the outlet, this does not guarantee stable power for the refrigerator. Start with basic checks:

• 🔌 Plug and socket: unplug the plug from the outlet and inspect it for melting, blackening or a burning smell. Plug another device into the socket (for example, a phone charger) - if it doesn’t work, the problem is in the socket or circuit breaker.
• ⚡ Automatic switch: check the panel on the landing or in the apartment. If the circuit breaker (usually 10–16 A) works, try turning it on again. If it knocks out repeatedly - do not turn on the refrigerator until the cause is eliminated (possibly a short circuit).
• 📊 Network voltage: refrigerators Bosch are sensitive to surges. Use a tester or multimeter to measure the voltage at the outlet. Norm: 220–240 V. If the value is lower 190 V or higher 250 V the problem is in the network, not in the equipment.

If everything is in order with the electricity, but the refrigerator still does not turn on, proceed to the next step. Please note: some models Bosch (for example, series VarioStyle) have overvoltage protection - during the jump they are turned off and do not turn back on automatically. In this case, you need to manually press the button Reset (usually located on the back panel or inside the camera).

2. Does the display show an error? Deciphering fault codes

Modern refrigerators Bosch are equipped with a self-diagnosis system. If an error code is on the display (for example, E:01, E:24 or the indicator is flashing Alarm), this significantly narrows down the search for the problem. Here are the most common codes and their meaning:

If your refrigerator Bosch is not equipped with a display (for example, models KGN33NW30 or KSV33NW30), pay attention to light indicators:

• 🔴 Red indicator: temperature is higher than normal (the compressor may have turned off).
• 🟡 Yellow indicator: mode super freezing or super cooling is active (can block normal mode).
• 🟢 Green indicator: everything is fine, but the refrigerator is not freezing? Check the temperature settings.

How to reset error E

24 without voiding the warranty?: If the display lights up E:24, try the following:

1. Unplug the plug from the outlet for 10–15 minutes.

2. Turn the refrigerator back on and immediately press the button combination Super Cooling + Fridge Temp (hold for 5 seconds).

3. If the error disappears, the problem was a board failure. If not, the module needs to be replaced (only in service!).

3. The compressor does not start: diagnostics and solutions

The compressor is the “heart” of the refrigerator. If it is not working, the refrigerator will not cool. Here's how to check its condition:

1. Listen to the compressor: put your ear to the back wall of the refrigerator (bottom). Normally you should hear a slight hum or click from the relay when starting up. Silence or loud cracking are signs of a malfunction.
2. Check the relay: this is a small box attached to the compressor. If you hear a knock when shaking or see carbon deposits, the relay needs to be replaced.
3. Measure resistance: unplug the refrigerator, remove the cover from the compressor and check the resistance of the windings with a multimeter. Normal values:
   • Between C-S: 20–40 Ohm
   • Between C-R: 10–20 Ohm
   • Between S-R: the sum of the two previous values

If the readings differ or tend to infinity, the compressor has burned out.

If the compressor hums but does not start, there are two possible reasons:

1. Motor jammed - replacement is required compressor.
2. Malfunction of the starting capacitor —you can replace it yourself (part cost: from 500 rubles).

4. Problems with the thermostat and electronic module

The thermostat (or thermostat in mechanical models) is responsible for turning the compressor on/off. If it breaks, the refrigerator may either not turn on at all or work without stopping. How to check:

• 🔧 Mechanical thermostat: Find the temperature control knob (usually inside the refrigerator compartment). Turn it from the minimum to the maximum value - you should hear a click (closing contacts). If there is no click, the thermostat is faulty.
• 📱 Electronic thermostat: in models with a display (for example, Bosch KAN92VI30), check whether the refrigerator responds to temperature changes in the menu. If the settings are not saved, the problem is in the control board.

The electronic module (board) is more difficult to diagnose. Signs of its malfunction:

• The refrigerator turns on for a few seconds and immediately turns off.
• The display shows chaotic symbols or does not respond to buttons.
• The compressor runs continuously, but the temperature does not drop.

Attention: board repair requires special equipment. Do not try to solder it yourself - this can lead to complete failure of the refrigerator.

5. The door does not close: seal, hinges, distortion

It would seem that there is something complicated here - I closed the door and that’s it. But if the seal is worn out or the refrigerator is not level, the chamber is not sealed, the temperature rises, and the compressor shuts down due to overload. Check:

Press the sheet of paper tightly to the seal and close the door - if the sheet falls out, the seal is faulty|

Check the hinges: the door should not sag or open spontaneously|

Make sure that the refrigerator is level (use level). Maximum permissible misalignment: 1–2°|

Inspect the seal for cracks, dirt or deformations (especially in the corners) -->

If the seal is damaged, it can be restore (in temporary mode) or replaced. To restore:

1. Heat the deformed areas with a hairdryer (temperature 60–70°C).
2. Shape the seal with your fingers and secure with masking tape for 12 hours.
3. Lubricate the rubber with silicone grease (do not use vegetable oil!).

But remember: this is a temporary measure. For a full repair, the seal needs to be replaced (cost: from 1,500 rubles).

6. Clogged drainage system and other “minor” breakdowns

Sometimes the refrigerator turns off not because of a serious breakdown, but because of “little things” that are easy to fix on your own:

• 💧 Clogged drainage hole: if water does not leave the refrigerator compartment, it can freeze. and block the fan (in models with NoFrost). This leads to overheating and shutdown. Clean the hole with a wire or a syringe with warm water.
• ❄️ Icing of the evaporator: in refrigerators with LowFrost (for example Bosch KGN39XW25R) ice on the evaporator can block air circulation. Defrost the refrigerator for 12-24 hours.
• 🔄 Fan failure: if in models with NoFrost does not work fan, the compressor overheats and turns off. Check whether the blade rotates when the door is open (in some models, the fan turns on only when the door is closed).

Another common problem is incorrect settingsFor example, if the mode is activated Holiday (vacation), the refrigerator is operating in economy mode and may appear to be "off". To deactivate it, press and hold the button Holiday (or Vacation) for 3 seconds.

How to defrost a Bosch refrigerator with NoFrost right?

1. Unplug the refrigerator.

2. Remove all food and shelves.

3. Leave the doors open for 12-24 hours (do not try to speed up the process with a hairdryer or hot water!).

4. After defrosting, wipe the internal surfaces with a solution of soda (1 tablespoon per 1 liter of water).

5. Turn on the refrigerator and let it work for 2-3 hours without food to stabilize the temperature.

7. When to call a technician: signs of serious breakdowns

Some breakdowns are not allowed. fix it yourself. Contact the service center Boschif:

• 🔥 It smells like burning or smoke is visible from under the refrigerator - a sign of a short circuit or fire.
• ⚡ The compressor hums, but does not start, and after turning off for 10-15 minutes the situation does not exist. changes.
• 💻 The display shows an error E:24 or E:FF after a reboot.
• 🧊 The refrigerator does not freeze, but the light inside is on —a freon leak is possible.

The cost of repair depends on the breakdown:

⚠️ Attention: if your refrigerator Bosch is under warranty (usually 2-5 years, depending on the model), do not disassemble it yourself! This will void the warranty. Contact an authorized service center - repairs will be provided. free.

8. Prevention: how to avoid repeated shutdowns

To ensure that the refrigerator Bosch serves for a long time and does not turn off suddenly, follow these recommendations:

• 🔌 Use a voltage stabilizer (especially if you live in area with frequent power surges). grille 2–3 kW.
• 🧹 Clean the rear grille from dust and pet hair at least once every 6 months. A clogged capacitor leads to overheating.
• 🚪 Do not slam the door - this will deform the seal and hinges. Close it smoothly.
• ❄️ Do not place hot foods into the refrigerator - this increases the load on the compressor.
• 🔄 Defreeze the refrigerator (even with NoFrost) once a year for prevention.

If your refrigerator Bosch is older than 10 years, think about replacing Modern models (for example, Bosch Serie 8) consume 30–40% less electricity and have improved protection against voltage surges.

FAQ: Frequently asked questions about turning off Bosch refrigerators

The Bosch refrigerator has turned off and does not turn on, but the light inside is on. What is the problem?

If the light is on, but the compressor does not work, there are three possible reasons:

1. Malfunction of the thermostat (for mechanical models) or control board (for electronic ones).
2. The compressor or start relay has burned out.
3. Freon leakage (in this case, the compressor may turn on briefly, but there will be no cold).

Check whether a click is heard when turning the thermostat knob (for mechanical models, if not). - replace the thermostat. For electronic models, board diagnostics are required.

After a power outage, the Bosch refrigerator does not turn on. What should I do?

Follow this algorithm:

1. Wait 10-15 minutes - the power surge protection may have tripped.
2. Check whether the machine in the control panel has tripped.
3. If the refrigerator does not turn on, unplug the plug from the socket for 1 minute, then plug it back in.
4. If there is an error on the display, reset it (see the section on error codes).
5. If nothing does not help - call a technician (the board or compressor may have burned out).

The Bosch refrigerator turns off 5-10 seconds after turning it on. Why?

This behavior is for two problems:

1. Malfunction of the starting relay - it turns on the compressor, but immediately turns it off due to a short circuit or winding break. The relay costs 500–1,500 rubles and is replaced in 10 minutes.
2. Interturn short circuit in the compressor —in this case, the compressor heats up, but does not start. Replacement is required (from 8,000 rubles).

To distinguish one from the other, touch the compressor after turning it off: if it is hot, it is the problem, if it is cold, the relay is to blame.

Is it possible to replace the compressor in a Bosch refrigerator yourself?

Technically yes, but this not recommended for three reasons:

1. Special equipment is required for vacuuming the system and charging freon.
2. Errors during replacement can lead to freon leakage or damage to the new compressor.
3. Independent repair will void the warranty (if it is still valid).

The cost of replacing the compressor in the service: 3,000–5,000 rubles (plus the price of the part If the refrigerator is older than 7 years, it is sometimes more profitable to buy a new one.

The Bosch refrigerator has turned off and “Alarm” is flashing on the display. What does it mean?

Indicator Alarm in one of the chambers Reasons: a critical increase. temperature in one of the cells. Reasons:

• The door is not closed properly or the seal is damaged.
• Hot food has been placed in the refrigerator.
• The drainage hole is clogged (in models with NoFrost).
• The temperature sensor or fan is faulty.

To reset the signal, press the button Alarm Reset (or hold Super Cooling 3 seconds). If the indicator lights up again, look for the cause of overheating.
