The new refrigerator does not turn off for a long time: reasons and solutions

Have you bought a new refrigerator, but it works non-stop, without turning off for rest? This is a warning sign that cannot be ignored. Normally, the compressor should be turned off periodically - usually for 10-20 minutes every hour. If the unit “threshes” for days on end, this not only threatens excessive energy consumption, but can also indicate serious malfunctions.

In this article we will analyze 7 main reasonswhy the new refrigerator does not turn off - from banal installation errors to factory defects. You will learn how to diagnose the problem yourself, when to call a professional, and in which cases you can do without repairs. We will also provide a checklist for checking the refrigerator before turning it on for the first time and tell you how to prevent breakdowns in the future.

Important: if the refrigerator works without stopping more than 24 hours, and a thick layer of ice forms in the freezer, this is a reason to urgently disconnect it from the network and call a specialist. Further operation may lead to overheating of the compressor and its complete failure.

1. Incorrect installation: 4 critical errors

Up to 30% of cases of continuous operation of a new refrigerator are associated with installation violations. Manufacturers clearly regulate operating conditions, but users often ignore these requirements. Here are the most common mistakes:

• 🔌 Lack of clearance for ventilation. The refrigerator should be positioned at a distance 5-10 cm from walls and furniture. If the rear grille fits tightly to the wall, heat is not dissipated, and the compressor works without interruption, trying to cool the chambers.
• ☀️ Direct sunlight or a heat source nearby. Installation next to a radiator, stove or window on the south side leads to overheating of the case. Even modern models Samsung RB37** or LG InstaView cannot cope with such a load.
• ⚖️ Uneven floor. If the refrigerator is tilted (even by 2-3°), the door may not close tightly. As a result, warm air penetrates inside, and the compressor tries to compensate for the leakage of cold.
• 🔄 Early switching on after transportation. After delivery, the refrigerator must “settle” 4-6 hours in a vertical position. If you turn it on immediately, the oil from the compressor may not have time to drain, which will lead to malfunctions.

How to check? Take a level and check that the installation is even. Measure the temperature in the room - it should be in the range 16-32°C (for most models). If the refrigerator is in an unheated garage or on a balcony in winter, it may not turn off due to the ambient temperature being too low.

⚠️ Attention: If the refrigerator is installed in a niche or built into furniture, make sure that the ventilation holes are not blocked. For models with a system No Frost (for example, Bosch KAN92VI20R) this is critical - without normal air exchange, the evaporator freezes and the compressor works without stopping.

2. Incorrect temperature settings

Many users mistakenly believe that the lower the temperature in the refrigerator, the better. However, setting minimum values ​​(-24°C in the freezer or +2°C in the main chamber) causes the compressor to work hard. This is especially true for inverter models (LG GR-B207, Samsung RT-28K5030), which automatically adjust to the specified parameters.

How to check the settings:

1. Open the instructions for your model and find the section "Recommended temperature conditions."
2. Make sure that the refrigerator the camera is set +4…+6°C, and in the freezer - -18…-20°C.
3. Check whether the mode Super Freeze or Super Coolis activated. These functions are designed for rapid cooling, but should turn off automatically after 6-12 hours.

If you have changed the settings, but the refrigerator still does not turn off, try resetting it to factory settings. To do this, you usually need to press and hold the button Reset or Power Cool for 5-10 seconds (see the instructions for the exact combination).

3. Overload with products or disruption of air exchange

New refrigerators are often bought “in reserve”, filling them to capacity with products. This leads to two problems:

1. Blocking the ventilation holes. In models with No Frost (for example, Indesit ITF 118), cold air circulates through special channels. If they are covered with bags or cans, the temperature in the chamber will rise and the compressor will work without stopping.
2. Thermal inertia. Large quantities of warm foods (for example, after purchasing in a supermarket) require long-term cooling. If you load the refrigerator "to capacity", it may not turn off 12-24 hours.

How to check:

• 📦 Make sure that the food does not touch the back wall (especially in models with drip system).
• 🌬️ Check that the ventilation grilles (usually located on the back wall or under the shelves) are not blocked.
• 🥩 Do not store hot foods in the refrigerator compartment - they increase the temperature and cause the compressor to work harder.

If the refrigerator has been overloaded, unload it by 30-40% and leave it running empty 6-8 hours. If after this the on/off cycle returns to normal, the problem was in the loading. Otherwise, look for another reason.

4. Malfunctions of sensors or electronics

In modern refrigerators, sensors and a control board are responsible for regulating the temperature. If at least one of the elements fails, the compressor may receive incorrect signals and work without stopping. Let's consider typical breakdowns:

• 🌡️ Fault temperature sensor. If the sensor in the refrigerator or freezer compartment transmits incorrect data (for example, it shows +10°C instead of +4°C), the compressor will try to cool the chamber to the set value indefinitely.
• 🔧 Failure of the control board. In refrigerators with an electronic unit (Samsung RL-44**, ATLANT XM 4625-101) after a power surge or incorrect connection, the firmware may fail. This leads to the compressor “freezing” in continuous operation.
• 🔌 Problems with the thermostat. In mechanical models (for example, Birusa 130), the thermostat often fails - it simply does not open the circuit, and the motor runs without interruption.

How to diagnose:

1. Disconnect the refrigerator from the mains on 10-15 minutes, then turn it on again. If the problem is a temporary electronics failure, this may help.
2. Listen to see if the thermostat relay clicks when it tries to turn off. The absence of clicks may indicate that it is broken.
3. If the refrigerator has a display, check the error codes. For example, in models LG the error ER FF indicates a fan malfunction, and ER DH a problem with the sensor.

⚠️ Attention: If you suspect an electronics malfunction, do not try to repair the board yourself. In 90% of cases this leads to even more serious damage. Contact a service center - diagnostics of sensors and boards require special equipment.

How to check a temperature sensor with a multimeter?

To do this you need:

1. Disconnect the refrigerator from the network.

2. Find the sensor (usually it is located behind the plastic panel in the camera).

3. Disconnect the connector and measure the resistance at room temperature (for most sensors it should be in the range 4-6 kOhm).

4. Place the sensor in a glass of cold water and measure the resistance again - it should change.

If the readings do not change, the sensor is faulty.

5. Freon leak or clogged capillary tube

If the refrigerator does not turn off, but doesn't freeze well this is a sign of a refrigerant leak or a blockage in the system. Freon circulates in a closed circuit, and any disruption of its movement leads to failures:

• ❄️ The condenser (grid at the back) remains cold even after long-term operation.
• 🔥 The compressor gets very hot, but the refrigerator compartment does not cool.
• 💧 Forms on the back wall condensation or ice (in models with a drip system).

Causes:

• 🛠️ Mechanical damage to tubes during transportation or installation.
• 🕳️ Corrosion of aluminum tubes (relevant for refrigerators older than 3 years, but sometimes found in new ones).
• 🔧 Clogged filter drier due to poor quality assembly.

This problem cannot be eliminated on your own - it requires refilling freon or replacement of the capillary tube (per. 2026) - from 3,500 to 8,000 rubles, depending on the model and complexity of the work.

⚠️ Attention: If you suspect a freon leak, immediately disconnect the refrigerator from network. Operating the compressor “dry” (without refrigerant) leads to its overheating and breakdown, and repairs will cost. 10,000-15,000 rubles.

Unfortunately, even new refrigerators can have hidden defects. According to statistics, up to 5% equipment is returned to service centers within the first month of operation. Let's consider typical cases:

• 🏭 Defective compressor. If the motor was initially assembled with a defect (for example, a leaky housing or damaged valves), it will not be able to create the necessary pressure in the system. As a result, the refrigerator. will work without stopping, but will not cool.
• 🔄 Incorrect charging of freon at the factory. Sometimes air or moisture gets into the system, which leads to corrosion and blockages.
• 🔧 Errors after warranty repairs. If the refrigerator has already been in service, there may be problems with soldering tubes, incorrect refilling of freon or damage to the insulation.

How to proceed:

1. Check the warranty card If the refrigerator is under warranty, contact the official service center of the brand.
2. Take a photo or make a video of the refrigerator in operation - this will help the technician quickly identify the problem.
3. If the repair has already been carried out, ask for a certificate of completion - this will help determine whether the service center is at fault.

Average time to eliminate a manufacturing defect:

Problem	Repair period	Cost (if not under warranty)
Replacement of compressor	3-7 days	from 8,000 rubles
Elimination of freon leakage	1-3 days	from 3,500 rubles
Replacement of the control board	2-5 days	from 5,000 rubles

7. External factors: power surges, climate

Sometimes the continuous operation of the refrigerator is not due to a breakdown, but to external conditions. Let's consider less obvious reasons:

• ⚡ Unstable voltage in the network. If the voltage drops below 190 V or rises above 240 V, the compressor may not work correctly. In some regions, this is a common problem - check the voltage. tester.
• 🌡️ Extreme temperatures. If the refrigerator is in a room where the temperature is higher +32°C or lower +10°C, it may not turn off. This is due to the limitations of the climate class (specified in the instructions).
• 🔌 Faulty socket. Poor contact or oxidation of the terminals leads to a voltage drop, which forces the compressor to work at the limit.

Solutions:

• Install voltage stabilizer (for example, Resanta ASN-1000 or Stil IS1000). This will protect the refrigerator from surges and extend the life of the compressor.
• If the refrigerator is in an unheated room, move it to a room with normal temperature or buy a model with an extended climate class (SN-T or ST).
• Check the outlet - connect another device to it (for example, a table lamp). If the lamp is blinking, the outlet needs to be repaired.

What to do if the refrigerator does not turn off: a step-by-step plan

If you have read the article and still do not understand why the refrigerator is working. without stopping, follow this algorithm:

1. Step 1. Check the installation.
   • Make sure the refrigerator is level (use a level).
   • Check ventilation gaps (5-10 cm on all sides).
   • Measure the temperature in the room (should be 16-32°C).
2. Step 2. Set the temperature.
   • Install in the refrigerator compartment +4…+6°C, in the freezer - -18…-20°C.
   • Disable the modes Super Freeze or Super Coolif they are active.
3. Step 3. Unload the refrigerator.
   • Remove excess food, leave only what is necessary.
   • Check whether the bags are blocking the ventilation holes.
4. Step 4. Diagnose faults.
   • Listen to whether the thermostat clicks when turned off.
   • Check whether the condenser (grid) is heating up back).
   • Pay attention to the error codes on the display (if any).
5. Step 5. Contact the service.
   • If self-diagnosis does not help, call a specialist.
   • Tell him the symptoms and what you have already checked - this will save time.

If the refrigerator is under warranty, do not try to repair it yourself - this may deprive you of the right to free repairs. Take a photo of the problem and contact an authorized service center.

FAQ: Frequently asked questions about the continuous operation of the refrigerator

How long can a new refrigerator work without stopping after the first turn on?

Normally - from 2 to 8 hours, depending on the model and room temperature If after 12 hours the compressor does not turn off, This is a cause for concern. Inverter refrigerators (LG, Samsung) can work longer due to smooth power control.

Can the refrigerator not turn off due to a dirty condenser?

Yes, if the grill on the back wall is clogged dust or dirt, heat exchange is disrupted and the compressor works without interruption. Clean the condenser with a soft brush or vacuum cleaner (at least once a year).

What to do if the refrigerator does not turn off, but freezes normally?

Most likely, the problem is in the temperature sensor refrigerator compartment or thermostat. Also check if the mode Vacation is turned on (in some models it turns off the refrigerator compartment, but the freezer continues to work).

How can you tell that the compressor is broken and not just working in overdrive?

Signs of a compressor breakdown:

• Severe noise, knocking or vibration during operation.
• The compressor housing is excessively hot (do not touch hand).
• The refrigerator does not cool, although the motor is running.
• An error appears on the display (for example, E1 or F5 in models Indesit).

In this case, urgent repair or replacement is needed compressor.

Is it possible to fill the refrigerator with freon?

No. Refilling the refrigerant requires special equipment (vacuum pump, pressure manifold) and certified freon. Incorrect filling can lead to explosion or poisoning (Freon is toxic if leaked). Contact the professionals.
