The freezer works, but the refrigerator does not: 7 reasons and how to fix the breakdown

You open the refrigerator, and instead of the usual chill you feel room temperature - while the freezer regularly freezes the ice and keeps it frozen. Is the situation familiar? This is one of the most common malfunctions of two-chamber refrigerators that owners of equipment Atlant, Indesit, Samsung and other brands encounter. In 80% of cases, the problem is solved without calling a technician - it’s enough to understand its cause.

In this article we will analyze why the freezer works, but the refrigerator does notwhich nodes are to blame for the failure, and what you can do yourself. You will learn how to check the thermostat, sensors, fan and system No Frost without special tools, and also when exactly you need the help of a professional. Do not rush to take the refrigerator to the service - in half the cases the fault is a banal frozen evaporator or lost settings.

We warn you right away: if your refrigerator is with one compressor (usually these are economy class models), the diagnostic algorithm will differ from the technicians with two motors (premium segment). We will analyze both options separately. Also pay attention to electronically controlled systems often break down due to board failures, and mechanical ones - due to breakdown of the thermostat.

1. How a refrigerator works: why the freezer can work, but the main chamber cannot

To understand why one chamber functions and the other does not, you need to understand the principle of operation of the cooling system. Modern refrigerators use two types of designs:

• 🔄 With one compressor —a common motor pumps refrigerant into both chambers, but the distribution of cold is controlled magnetic valve or damper.
• ❄️ With two compressors —each motor is responsible for its own chamber (freezing and refrigerating), which simplifies diagnostics.

In the first case (one compressor), the cold first enters the freezer, and then through evaporator and the tube system - into the refrigerator compartment. If a blockage occurs along this path (for example, frosting or a broken valve), the refrigerator compartment stops cooling, but the freezer continues to operate. In the second case (two compressors), the problem usually lies in malfunction of one of the motors or its control circuit.

It is also important to consider the type of defrosting:

• 🧊 Drip system (found in budget models Biryusa, Pozytron) - the evaporator is located on the rear wall, the frost melts naturally.
• ❄️ No Frost (popular in LG, Samsung, Beko) - air circulation is provided by a fan, and defrosting occurs automatically.

In systems No Frost a common cause of malfunction is icing of air ducts or fan failure. In drip refrigerators, the culprit is usually thermostat or freon leak.

2. TOP 7 reasons why the refrigerator does not cool, but the freezer works

We have collected the most likely causes of failure, sorting them by frequency of occurrence. Start checking from the first points - they require minimal skills and tools.

Now let's look at each reason in more detail.

2.1. Clogged drainage hole or defrost system

If water accumulates in the refrigerator compartment and ice forms on the back wall, it is most likely clogged drainage hole. The water does not go into a special tank, but freezes, blocking air circulation. This problem is typical for models with a drip system (Atlant, Stinol).

How to check:

1. Unplug the refrigerator.
2. Remove all food from the refrigerator compartment.
3. Find the drainage hole (usually at the bottom of the back wall) and clean it with a cotton swab or wire.
4. Rinse the hole with warm water and soda.

Disconnect the refrigerator from the mains|

Find a drainage hole (usually at the bottom of the back walls)|

Clean the hole and rinse with water-->

If after cleaning the problem remains, it may be clogged drain hose (purge required) or faulty evaporator heater (in systems No Frost).

2.2. Failure of the thermostat (thermostat)

The thermostat is a sensor that controls the temperature in the refrigeration chamber. If it fails, the compressor either does not turn on at all, or. works without stopping. In models with mechanical control (for example, Biryusa 130), the thermostat often breaks due to oxidation of the contacts.

Symptoms of malfunction:

• 🔴 The compressor does not starts, although the freezer is working.
• 🔄 The motor runs constantly without turning off.
• 🌡️ The temperature in the refrigerator compartment does not correspond to the set temperature (too high or low).

How to check the thermostat:

1. Disconnect the refrigerator from the network.
2. Remove the protective casing (usually located inside the chamber or behind the refrigerator).
3. Find the thermostat - this is a small box with a tube attached to the evaporator.
4. Ring the contacts with a tester (in the “circuit check” position). At room temperature they should be closed.

If the thermostat is faulty, it must be replaced. For models Indesit and Ardo universal thermostats are suitable K59 or Danfoss 077B6.

2.3. Freezing of the evaporator in No Frost systems

In refrigerators with No Frost (for example Samsung RL-34, LG GA-B489), the cold is distributed among the chambers using a fan. freezes, the air stops circulating, and the refrigerator compartment stops cooling, although the freezer is working normally.

Causes of freezing:

• ❄️ Breakdown heater defrost (heating element).
• 🕒 Malfunction defrost timer.
• 💨 Clogged air channels ice.

How to eliminate:

1. Turn off the refrigerator for 12-24 hours to completely defrost.
2. After defrosting, check the operation of the fan - it should blow cold air evenly.
3. If after 1-2 days the problem returns, the heater or timer needs to be replaced.

What will happen if you do not repair a frozen evaporator?

If you ignore freezing, ice will completely block the air ducts, and the refrigerator compartment will stop cooling even after defrosting. In the worst case, the compressor will wear out, which will lead to its breakdown (replacement cost starts from 8,000 rubles).

3. Diagnosis of faults in single-compressor and double-compressor refrigerators

The problem-finding algorithm depends on how many compressors are in your refrigerator. This can be determined by:

• 📋 Technical data sheet (the number of motors is indicated).
• 👁️ Appearance: two compressors are usually located at the bottom rear (two black cylinders).
• 🔧 Operating behavior: in On two-compressor models, the freezer and refrigerator can be turned off independently.

If you are not sure, look at the refrigerator model on the manufacturer's website - the configuration is always indicated there.

3.1. Single-compressor refrigerators: checking the magnetic valve

In models with one compressor (Atlant MHM 1705, Stinol 101), the cold is distributed between the chambers using magnetic valve (or solenoid valve). If it jams, freon flows only into the freezer, and the refrigerator compartment remains warm.

Symptoms valve failure:

• 🔊 Clicking when switching modes (sometimes audible even without a stethoscope).
• ❄️ The freezer works, the refrigerator does not (or vice versa, if the valve is stuck in a different position).
• 📉 Temperature in the refrigerator compartment rises to +15...+20°C.

How to check:

1. Turn off the refrigerator.
2. Find the valve - it is located on the tube between the compressor and the evaporator (usually at the back, at the bottom).
3. When you turn on the refrigerator in The valve should click within 5-10 minutes. If there is no click, it is faulty.

Replacing the valve will cost 2,500–4,000 rubles (depending on the model). In some cases it helps tapping the valve (carefully, with a wooden tool handle), but this is a temporary solution.

3.2. Two-compressor refrigerators: checking a separate circuit

In refrigerators with two compressors (Liebherr CN 4015, Samsung RB-30 J3200), each motor is responsible for its own chamber. If the refrigerator compartment does not work and the freezer freezes, the problem lies in:

• 🔋 Refrigerator compartment compressor (does not start or works intermittently).
• 📡 Board controls (does not give a signal to turn on).
• 🧊 Freon leak in the refrigeration compartment circuit.

Diagnostics:

1. Listen to see if the refrigeration chamber compressor turns on (a slight hum should be heard).
2. Check whether the indicators on the control panel are lit (if not, there may be a problem with the board).
3. Inspect the back wall of the refrigerator for oil stains (a sign of a freon leak).

If the compressor does not start, but you hear the relay clicking, most likely the motor jammed or the winding has burned out. In this case, a replacement will be required (cost - from 5,000 rubles).

4. Freon leak: how to determine and what to do

Freon is a refrigerant that circulates through the system and provides cooling. If this happens leak, the compressor runs “idle”, pumping air instead of freon. This is one of the most serious breakdowns, as it requires recharging the system searching for the leak.

Signs of a freon leak:

• 🔊 The compressor works without stopping, but does not cool.
• 🧊 There is no condensation on the back wall of the refrigerator (normally there should be some).
• 🛠️ Oil stains are visible on the tubes or compressor (freon comes out along with the oil).
• 🌡️ Temperature in the refrigerator compartment rises to room temperature.

What to do:

1. Disconnect the refrigerator from the mains.
2. Inspect the back wall for oil smudges (especially in places where the tubes are soldered).
3. If you find a leak (usually microcracks or corrosion), do not try to solder it yourself - special equipment is required.
4. Call a specialist to vacuum systems and refill with new freon.

Repair cost:

• Leak diagnostics - from 1,500 rubles.
• Refilling with freon (depending on type) - 3,000–6,000 rubles.
• Replacement of pipes or evaporator (for serious damage) - from 8,000 rubles.

5. Problems with the electronic control board

In modern refrigerators with electronic control (LG, Samsung, Bosch) the board is responsible for the distribution of cold. If it fails, the following failures are possible:

• 📛 The refrigerator does not respond to temperature settings.
• 🔄 The compressor turns on and immediately turns off (click-click mode).
• 💡 Errors are displayed on the display (for example, E1, F2 —the decoding is in the instructions).
• ❄️ The freezer works, but the refrigerator does not (the board does not send a signal to the valve or fan).

Causes of board failure:

• ⚡ Power surges in the network.
• 💦 Moisture ingress (condensation or leakage).
• 🕒 Natural wear and tear (after 7-10 years).

How to check:

1. Unplug the refrigerator for 10–15 minutes, then turn it on again. Sometimes this resets errors.
2. See if the indicators on the panel are lit. If not, the problem is in the power supply to the board.
3. Ring the fuse on the board (if you have the skills to work with a multimeter).

Repairing the board will cost 3,000–7,000 rubles. In some cases it helps flashing (if there is a software failure). For models Samsung i LG you can often find firmware on thematic forums (for example, 4PDA).

⚠️ Attention! If you are not confident in your soldering skills, do not try to repair the board yourself. Incorrect actions can lead to a short circuit or breakdown of other components.

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

Not all faults can be fixed by yourself if:

• 🔧 Required refilling freon (needs vacuum equipment).
• 🔌 There are signs oil leaks from the compressor (dark spots, burning smell).
• ⚡ The refrigerator electric shock or sparks (electrical problem).
• 💻 The display shows an error that cannot be reset (E5, F7 etc. etc.).
• 🛠️ You need replace the compressor or a control board.

Average prices for repairs (Moscow and regions, 2026):

Before agreeing to repairs, ask the technician:

1. Precisely state the cause of the breakdown (not “the board burned out,” but “the triac burned out Q1 on the power line fan").
2. Provide a guarantee for the work (minimum 6 months).
3. Show replaced parts (if it is a compressor or board).

⚠️ Attention! If the technician suggests “topping up the freon without looking for a leak,” refuse - this is a temporary solution. After 1–2 months, the gas will evaporate again, and the problem will return.

7. Prevention: how to avoid refrigerator breakdowns

To make the refrigerator last longer without failures, follow simple rules:

• 🧊 Defrosting: even in systems No Frost every year, turn off the refrigerator for 12–24 hours for preventative cleaning.
• 🔌 Voltage stabilizer: connect the refrigerator through a surge protector or stabilizer (especially important for country houses and old houses).
• 🚪 Tight closure doors: check the sealing rubber bands (they should fit without gaps).
• 🧹 Cleaning the back wall: once every six months, vacuum the condenser (grid at the back) - this will improve heat transfer.
• 🌡️ Temperature: do not place the refrigerator next to the radiator or stove (optimally - at +18...+22°C indoors).

Also avoid:

• 🚫 Overloading the chambers (especially freezers) - this disrupts air circulation.
• 🚫 Storing hot foods - steam accelerates the formation of ice.
• 🚫 Opening the door frequently in hot weather (the compressor wears out).

If your refrigerator is no longer new (over 7 years old), get into the habit of checking once a month:

• Temperature in the chambers (optimally: +4°C in the refrigerator, –18°C in the freezer).
• The presence of frost on the back wall (in drip systems it should not be).
• Compressor noise (extraneous knocking or hum is a sign of wear).

Frequently asked questions (FAQ)

❓ The refrigerator does not cool, but the freezer is working - what should you do first?

Start with the simplest checks:

1. Make sure that the refrigerator is connected to the network and the lights are on indicators.
2. Check whether the temperature settings have gone wrong (perhaps you accidentally set +10°C).
3. Defrost the refrigerator for 12 hours - if the problem is freezing, this will help.
4. Inspect the drainage hole and clean it.

If all else fails, proceed to diagnosing the thermostat or valve (depending on the model).

❓ Is it possible to refill freon yourself?

No, it is dangerous and technically difficult. To refill freon you need:

• Special equipment (vacuum pump, pressure gauges, freon cylinder).
• Knowledge of the type of refrigerant (R134a, R600a, etc.).
• Ability to solder copper pipes (if leak).

Errors during refueling can lead to explosion of a cylinder (freon under pressure) or compressor breakdown. Entrust it to the professionals.

❓ How much does it cost to repair if the refrigeration chamber does not work?

The cost depends on the reason:

• Replacement thermostat — 1 500–3 000 ₽.
• Board repair — 3 000–7 000 ₽.
• Replacing the magnetic valve — 2 500–4 000 ₽.
• Refilling freon — 3 500–6 000 ₽.
• Replacing the compressor — 5 000–12 000 ₽.

If the refrigerator is older than 10 years, sometimes it is more profitable to buy a new one (especially if replacement is required compressor or circuit board).

❓ Why does the refrigerator not cool after defrosting?

Possible reasons:

• The system got into wet air —you need to vacuum and refill the freon.
• Burned compressor (if it does not start after defrosting).
• Problems with starting relay (clicks, but the motor does not start).
• In models No Frost the defrost heater could burn out defrost heater.

Try turning off the refrigerator for 1 hour, then turning it on again. If it doesn’t help, call a specialist.

❓ Which refrigerator models break down more often?

According to statistics from service centers (2023–2026), most often owners face this problem:

• Atlant (MHM, XM series) - problems with thermostats and leaks freon.
• Indesit (models with No Frost) - evaporator freezing and board failure.
• Samsung (RB, RL series) - electronic module failures.
• Stinol - drainage system blockages.
• Beko —failures of magnetic valves.

The most reliable in this regard are Liebherr i Bosch (less likely to require repairs in the first 7-10 years).
