The refrigerator does not cool well, but the freezer is working: reasons and what to do

Have you noticed that the refrigerator compartment has stopped coping with its task: food spoils faster, condensation forms on the walls, and the temperature inside is higher than normal? At the same time, the freezer compartment works like a clock - the ice does not melt, and the ice cream remains solid. This situation is more common than it seems and is usually associated with uneven distribution of cold between compartments. In 80% of cases, the problem can be fixed without calling a technician, but to do this you need to correctly diagnose the cause.

In this article we will look all possible scenarioswhy the refrigerator does not cool well, but the freezer works properly - from the banal clogged drainage to serious compressor failures. You will learn how to check the cooling system yourself, when to sound the alarm and call a specialist, and in which cases a simple adjustment is enough. We will pay special attention to models with a system No Frost and two-compressor refrigerators, where the diagnostic algorithm is different.

We warn you right away: if your refrigerator belongs to the premium segment (Liebherr, Samsung Family Hub, Bosch VitaFresh), some tips may not be suitable due to unique cooling technologies. In this case, it is better to contact an authorized service center.

1. A clogged drainage system is the most common cause

If the refrigerator compartment is not cooling well, but the freezer is working fine, first check drainage hole. It is located on the rear wall of the refrigerator compartment (usually at the bottom) and serves to drain condensate. Over time, it becomes clogged with crumbs, food debris or mold, which leads to:

  • 🔹 Water accumulation under the vegetable drawers
  • 🔹 Formation ice on the back wall
  • 🔹 Impaired air circulation (cold does not enter the main chamber)

How to clean the drainage yourself:

  1. Unplug the refrigerator and remove all products.
  2. Find the drainage hole (sometimes it hidden under a plastic plug). data-i="77">wire
  3. Use cotton swab, wire or special brush (included with some models Indesit And Atlant).
  4. Rinse the hole with warm water with the addition of baking soda (1 tablespoon per 250 ml).

After cleaning, turn on the refrigerator and check if the water leaves. If the problem remains, the blockage may be deeper - in the drain tube that leads to the container on the compressor.

How to check that the blockage has been cleared?

After cleaning the drainage, place a glass of water in the refrigerator compartment (do not close the lid). After 12 hours, check:

- If there is no ice on the back wall and the water in the glass is cold, the problem is solved.

- If the ice remains and the water is in glass at room temperature - the blockage has not been eliminated or the reason is different.

2. Malfunction of the blower fan (for models with No Frost)

Refrigerators with the system No Frost (Samsung, LG, Bekoare equipped with a fan that evenly distributes cold air between the freezer and the refrigerator compartment. If it fails, the freezer continues to work (since the cold is generated by the evaporator), and the refrigeration compartment stops cooling.

Signs of fan failure:

  • 🔊 No noise (normally a slight hum should be heard during operation)
  • ❄️ Evaporator freezing (ice on the back wall of the freezer)
  • 🌡️ Sharp temperature drop between compartments (in the freezer -20°C, in the refrigerator +15°C)

How to check the fan:

  1. Unplug the refrigerator.
  2. Remove the back panel in the freezer (usually secured with latches or screws).
  3. Try turning the fan blades by hand. If they do not rotate or make a creaking noise, the problem is in the bearings.
  4. Connect the refrigerator and listen to whether the fan starts 5-10 minutes after switching on.
📊 Is your refrigerator with a No Frost system?
Yes, with complete No Frost
Yes, only in the freezer
No, drip system
I don’t know

If the fan does not work, the reasons may be the following:

Cause How eliminate Repair cost (approximately)
Frozen blades Defreeze the refrigerator for 12-24 hours, dry it Free
Motor breakdown fan Replacement of the motor (soldering iron and experience required) RUB 1,500–3,000
Wiring break Call with a tester, restore contact 500–1,500 rub.
Failure of the control board Diagnostics in the service, replacement of the board 3,000–8,000 rub.

3. Freon leak or capillary tube blockage

Freon is a refrigerant that circulates through the refrigerator system and provides cooling. If it occurs leakage or clogging of the capillary tubes (along which it moves), the refrigerator compartment stops cooling, and the freezer can still operate for some time due to the remaining refrigerant.

Signs of a freon leak:

  • 🔧 The compressor runs without stopping (no on/off cycles)
  • 🧊 The condenser (grid at the back) does not heat up
  • 📉 The temperature in the refrigerator increases gradually (not sharply)

How to check:

  1. Unplug the refrigerator and move it away from the wall.
  2. Inspect capillary tube (thin copper tube running from the compressor to the evaporator).
  3. If there are oily stains or swelling on it, this is a sign of a leak.
  4. Check condenser (grid at the back): normally it should be warm. If it is cold, there is no freon.

Inspect the capillary tube for damage|

Check the temperature of the condenser (should be warm)|

Listen to the compressor (if there is a leak, it works without pauses)|

Pay attention to oil traces on the tubes -->

Freon leakage is serious damage that cannot be repaired on your own. You will need:

  1. Find the location of the leak (using a leak detector).
  2. Repair the damage (soldering or replacing the tube).
  3. Evacuate the system and fill in a new one freon.

Repair cost: from 3,500 to 10,000 rubles, depending on the model. In some cases (for example, if the leak occurs in the foamed part of the housing), repair may not be cost-effective.

4. Failure of the thermostat or temperature sensor

The thermostat (or thermostat) is responsible for maintaining the set temperature in the refrigerator compartment. If it fails, the compressor either does not turn on at allor works without stopping, but the cold does not flow in the required volume. In this case, the temperature in the freezer can remain normal, since it is cooled by a separate circuit (in two-compressor models) or with a higher priority (in single-compressor models).

How to check the thermostat:

  1. Turn off the refrigerator from the mains.
  2. Remove the thermostat protective cover (usually located inside the refrigerator compartment or on the top panel).
  3. Locate the two wires going to the thermostat and connect them to each other (use a screwdriver with an insulated handle!).
  4. If after closing the compressor starts, the thermostat is faulty.

The cost of replacing the thermostat:

  • 🔧 Mechanical thermostat: 800–2,000 rubles. (depending on the model)
  • 🔧 Electronic sensor: 1,500–4,000 rubles.

If you are not confident in your abilities, it is better to call a specialist. Incorrect connection of the thermostat can lead to compressor overheating or short circuit.

5. Problems with the door seal

A worn or damaged seal allows warm air into the refrigerator compartment, causing the temperature to rise. The freezer can work normally because:

  • 🔄 It has more powerful thermal insulation.
  • 🔄 It opens less often.
  • 🔄 In some models (Liebherr, Siemens) the freezer has a separate circuit cooling.

How to check the seal:

  1. Close the refrigerator door and try to insert a sheet of paper between the seal and the body If the sheet passes easily or falls out, the seal is not airtight..
  2. If the sheet passes easily or falls out, the seal is not airtight.
  3. Inspect the rubber for cracks, deformations or contamination.

How to restore the seal:

  • 🧼 Cleaning: wash the seal with warm water and soap, dry.
  • 🔥 Restoring shape: heat the rubber with a hairdryer (not higher than 60°C) and shape it with your hands.
  • 🛠️ Replacement: if the seal is torn or has lost elasticity, it needs to be replaced (cost: 1,000–3,000 rubles).
How to temporarily improve the fit of the seal?

If a new seal has not yet been purchased, but the refrigerator is needed urgently "reanimate", use magnetic tape (sold in hardware stores). Glue it around the perimeter of the door - this will improve the tightness for 1-2 weeks.

6. Malfunction of the control board

In modern electronically controlled refrigerators (Samsung, LG, Haier), control boardis responsible for the distribution of cold. If it fails, the following symptoms may be observed:

  • 📛 The refrigerator compartment does not cool, but the freezer is working.
  • 🔄 The compressor turns on for 5-10 seconds and turns off.
  • 📵 The display shows an error (for example, E1, F2 or OF OF on models Indesit).

Causes of board failure:

  • ⚡ Voltage surges in network.
  • 💧 Moisture ingress (for example, during defrosting).
  • 🔥 Overheating due to poor ventilation.

What to do:

  1. Unplug the refrigerator for 10-15 minutes, then turn it on again. Sometimes this helps. reset the error.
  2. Check fuse on the board (if it is burnt out, replace it).
  3. If the board is damaged (blackened tracks, swollen capacitors) - replacement is required.

Repair cost:

  • 🔧 Diagnostics: 500–1,000 rubles.
  • 🔧 Replacement of the board: 3,000–10,000 rubles (depending on the model).

7. Two-compressor refrigerators: individual reasons

If your refrigerator has two compressors (for example, Atlant, Stinol, Gorenje), then the freezer and refrigerator compartment are cooled independently. In this case, if the refrigerator compartment does not cool, but the freezer is working, the problem lies in:

  • 🔧 Refrigeration compressor chamber (may not turn on or work ineffectively).
  • 🔧 Refrigeration compartment thermostat.
  • 🔧 Freon leak in the refrigeration chamber circuit.

How to diagnose:

  1. Listen to see if the refrigeration chamber compressor starts (it is usually located on the right or left below).
  2. Check the temperature of the condenser (grids at the back) - if it is cold, the compressor does not work.
  3. Inspect start relay the compressor (black box on compressor) - if it gets hot or smells like burning, it needs to be replaced.

Repair cost:

Breakage Repair cost
Replacement compressor 5,000–12,000 rub.
Replacing the start relay 800–2,000 rub.
Refilling freon into the refrigeration chamber circuit 3,500–7,000 rubles.

In two-compressor refrigerators, repairs are usually more expensive, but there is a plus: if one compressor breaks down, the second one continues to work, and the food in the freezer does not spoil.

What to do if nothing helps?

If you have tried all the methods, but the refrigerator compartment still does not cool, and the freezer is working, perhaps the problem lies in:

  • 🔧 Clogged filter drier (replacement required).
  • 🔧 Failure of the four-way valve (in inverter models).
  • 🔧 Evaporator malfunctions (freezing or corrosion).

In these cases, you cannot do without professional diagnostics, contact the service center, having previously clarified:

  • 📋 Refrigerator model (located on the sticker inside or on the back).
  • 📋 Symptoms of breakdown (when they appeared, how they manifest themselves).
  • 📋 Have there been any attempts at self-repair.

If the refrigerator is under warranty, do not try to repair it yourself - this may lead to refusal of warranty service.

FAQ: Frequently asked questions

❓ The refrigerator stopped cooling after defrosting. What to do?

Most likely, after defrosting the compressor did not turn on or the drainage was clogged. Check:

  1. Is the refrigerator connected to the network (sometimes after defrosting they forget to plug in the plug).
  2. Is the compressor running (should vibrate slightly and be warm).
  3. Is the drain hole clean.

If the compressor does not start, wait 12 hours - it may be "thawing" after a long period of inactivity.

❓ Can the refrigerator cool poorly? because of the heat in the room?

Yes, if the room temperature is above 30°C, the refrigerator may not be able to cope with the load. In this case:

  • Set the temperature control to maximum.
  • Do not open the door unless necessary.
  • Check whether the refrigerator is located next to the battery or stove.

If the problem does not disappear, it may be necessary refilling freon or cleaning the condenser.

❓ Why in the refrigerator with No Frost ice builds up in the freezer, but the refrigerator compartment does not cool?

This is a sign. In refrigerators faulty defrost system. In refrigerators No Frost the evaporator should automatically defrost every 8-12 hours. If this does not happen, the ice blocks the fan and the cold stops flowing into the refrigerator compartment. replacement:

  • 🔥 defrost heating element (heating element).
  • 🕒 defrost timer (in mechanical systems).
  • 📛 Defrost sensor (in electronic systems).
❓ How much does it cost to repair if the refrigerator does not cool and the freezer works?

The cost depends on the cause:

Breakage Cost (RUB)
Drainage cleaning Free (on your own) or 500–1,000 (in service)
Replacement of No Frost fan 1 500–3 000
Replacing the thermostat 800–2 000
Refilling freon 3 500–7 000
Replacing the control board 3 000–10 000

It is difficult to name the exact price - it depends on the model of the refrigerator and the region. In Moscow and St. Petersburg, repairs are usually 20-30% more expensive than in the regions.

❓ Is it possible to use a refrigerator if it does not cool well?

Short-term (1-2 days) - yes, but with caution:

  • 🥩 Store perishable foods (meat, fish, dairy) in the freezer.
  • 🥬 Keep vegetables and fruits in the coldest areas (usually at the back wall).
  • 🧊 Use cold accumulators (if available).

Prolonged use of a faulty refrigerator can lead to:

  • 🦠 Reproduction of bacteria (especially at temperatures above +5°C).
  • 🔥 Overheating of the compressor (if it works without stopping).
  • 💸 More expensive repairs (for example, if a compressor burns out due to a freon leak).
