The freezer does not freeze - causes and ways to fix the breakdown

Have you opened the freezer, but instead of the usual cold you feel room temperature? The food began to thaw, and frost appeared on the walls or, conversely, everything was dry, like in the desert? This problem is familiar to many owners of refrigerators - from budget Indesit and Atlant to premium Liebherr and Samsung. But don’t rush to call a technician: in 60% of cases, the malfunction can be fixed on your own, saving on repairs.

In this article we will look at why the freezer stops freezing - from banal icing to serious compressor breakdowns. You will learn how all possible reasons, due to which the freezer stops freezing - from banal icing to serious compressor breakdowns. You will learn how to diagnose the problem by external signs, what manipulations you can do yourself, and when exactly it’s time to call the service center. We will pay special attention models with the No Frost systemwhere malfunctions are often disguised as “normal” operation of equipment.

We will immediately warn you: if your refrigerator under warranty Do not disassemble it yourself - this will void the warranty. But even in this case, knowing the reasons for the breakdown will help control the honesty of the craftsmen and avoid unnecessary expenses.

1. Check the obvious: 5 “everyday” reasons

Before committing complex breakdowns, eliminate simple operating errors. Often the freezer stops freezing due to incorrect settings or external factors that the user does not even notice.

• 🔌 No power. Check if the indicator on the control panel is lit. Perhaps the plug has fallen out of the socket, the circuit breaker on the panel has tripped, or the power cable has been broken (this is important for refrigerators with a short cord that are often moved).
• ❄️ Defrost mode. Some models (for example Bosch KGN39XL45 or LG GA-B409) have an automatic defrost function that turns off refrigeration for 10-30 minutes. Wait an hour - if the temperature does not return, look for another reason.
• ⚙️ Temperature settings are lost. Optimal mode for the freezer: -18°C. If someone accidentally changed the value to -12°C or -8°C, the camera will work at half capacity. Check the display or mechanical regulator.
• 🚪 The door is not closed tightly. Even a small gap of 2–3 mm leads to the entry of warm air. Inspect the rubber seal for cracks or deformation. Carry out a test with a sheet of paper: if it is easily pulled out when the door is closed, the seal is broken.
• 🌡️ Heat in the room. If the refrigerator is located next to a stove, radiator, or in direct sunlight, the compressor may not be able to cope with the load. Normal operating temperature for most models: +16…+32°C.

If all the items from the list are in order, but the freezer still does not work, we move on to diagnosing technical faults.

2. Evaporator icing: when No Frost fails

Systems No Frost i Low Frost should prevent ice formation, but in practice even they require maintenance. If the freezer has stopped freezing, and a thick layer of snow or ice is visible on the back wall, the problem is icing of the evaporator. Reasons: Due to the melting of ice, water does not flow into the pan, but freezes on the evaporator, forming a “fur coat”. Relevant for models evaporator icing.

Reasons:

• ⏳ The drainage hole is clogged. Due to the melting of ice, water does not flow into the pan, but freezes on the evaporator, forming a “fur coat”. Relevant for models Atlant MXM-1808, Biryusa 110.
• 🌀 The fan is faulty. In No Frost systems, a fan drives cold air around the chamber. If it breaks (for example, due to icing of the blades), the cold ceases to be distributed.
• 🔥 The defrost heater has burned out. This element is turned on periodically to melt the ice on the evaporator. If it burns out, ice accumulates, blocking the circulation of the refrigerant.

How to fix:

1. Unplug the refrigerator and defrost it at least 12 hours (ideally - a day). Do not use a hairdryer or hot water - a sudden temperature change can damage the plastic.
2. After defrosting, clean the drainage hole at the bottom of the chamber. Use a cotton swab or a special brush (included with some models).
3. Check the operation of the fan: when the door is open, it should start in 1-2 minutes. If not, replacement may be required.

3. Freon leak: how to recognize and what to do

Freon is a refrigerant that circulates through the refrigerator system, providing cooling. If the tubes are damaged, gas escapes and the freezer stops freezing. Signs of a leak:

• The compressor is running continuously (no on/off cycles).
• Condenser (grid on the rear wall) room temperature (normally it should be warm).
• There are oily spots on the floor under the refrigerator (freon is mixed with oil from the compressor).

Causes of leakage:

• 🛠️ Mechanical damage tubes (for example, when moving the refrigerator or careless defrosting with a knife).
• 🕳️ Corrosion aluminum tubes (relevant for older models or with high humidity in the room).
• 🔧 Defective soldering (found in new refrigerators if the assembly was of poor quality).

Freon leakage cannot be eliminated independently - special equipment is required to evacuate the system and charge it with new refrigerant. Average repair cost: 3,500–8,000 ₽ (depending on the model and volume of freon).

⚠️ Attention: Freon is non-toxic, but if leaked in large quantities it can cause dizziness. If you smell a chemical smell, ventilate the room and turn off the refrigerator.

4. Compressor failure: symptoms and diagnosis

The compressor is the “heart” of the refrigerator. If it fails, the freezer stops freezing completely. Signs of malfunction:

• 🔇 The compressor does not start (no characteristic hum).
• 🔥 The compressor housing is too hot (normally it should be warm, but not scalding).
• ⚡ The refrigerator knocks out the machine when turned on (indicates an interturn short circuit).
• 🕒 Compressor works, but does not turn off (may indicate a loss of power).

How to check the compressor:

1. Unplug the refrigerator and remove the back cover (in most models it is secured with latches or screws).
2. Find the compressor - this is a black “tank” with tubes and a relay on top.
3. Test the windings with a multimeter:
   • Resistance between contacts C-S (common winding and starting winding): ~20–40 Ohm.
   • Resistance between C-R (common and working): ~10–20 Ohm.
   • Resistance between S-R (starting and operating): the sum of the two previous values.

If the resistance is equal 0 (short circuit) or ∞ (open), the compressor is faulty.

The cost of a new compressor is from 4,000 to 15,000 rubles (depending on the model). Replacement with labor will cost 6,000–20,000 rubles. For refrigerators older than 10 years, such repairs are often unprofitable - it’s cheaper to buy a new one.

What to do if the compressor hums, but does not start?

This is a sign of a malfunction start relay the part that “starts” the compressor. The relay costs 500–1,500 rubles and is replaced in 10 minutes. To check it, shake the part: if you hear a knocking sound (as if something is loose inside), the relay is burnt out and requires replacement.

5. Malfunction of the thermostat or electronic board

The thermostat (in mechanical models) or the electronic control unit (in modern refrigerators) are responsible for regulating the temperature. If they fail, the compressor either does not turn on or works chaotically.

Signs of a thermostat failure:

• 🌡️ The refrigerator does not respond to temperature changes on the regulator.
• 🔄 The compressor turns on for 5-10 seconds and immediately turns off.
• ❄️ The temperature in the freezer is too low (for example, -25°C instead of -18°C).

How to check the thermostat:

1. Find the thermostat (usually it is located next to the temperature control knob).
2. Remove the terminals and test the contacts with a multimeter in circuit test mode. At room temperature there should be short circuit (resistance ~0 Ohm) between the contacts.
3. Place the thermostat in ice for 10 minutes - if it is is working, the circuit will break.

Signs of a faulty electronic board:

• 📱 Errors flash on the display (for example, E1, F2 —for decoding, see the instructions for the model).
• 🔄 The refrigerator spontaneously turns on/off.
• 🎛️ The buttons on the control panel do not work.

⚠️ Attention: If the control board fails due to a power surge, install voltage stabilizer before replacing it (for example, Resanta ASN-1000). again.

6. Capillary tube clogged: why the refrigerator “chokes”

The capillary tube is a thin channel through which freon enters the evaporator. Over time, it can become clogged due to:

• 🛢️ Oil deposits (a mixture of freon and oil forms paraffin plugs).
• 🔧 Metal shavings (entered by careless repair).
• 🧊 Moisture in the system (if the refrigerator was left turned off for a long time with the door open).

Signs of blockage:

• The compressor works without stopping, but the freezer does not cool.
• Condenser (grid at the back) cold (normally it should heat up).
• The evaporator tube is covered with frost only at the beginningand then dry.

The blockage can only be eliminated flushing the system with special equipment. Average cost of repair: 5,000–10,000 rubles. In some cases, the capillary tube needs to be replaced.

7. When to call a technician: 3 critical cases

Some breakdowns require professional intervention. Do not delay calling a technicianif:

1. The compressor does not start, but you have ruled out problems with the relay and thermostat. It is possible turn-to-turn breakdown or a winding break.
2. A chemical smell has appeared in the refrigerator (indicates a freon or oil leak). from the compressor).
3. On the display shows an errorwhich cannot be reset (for example, F5 in Samsung or H1 in LG).

Average prices for repairs in service centers (Moscow and the region, 2026):

⚠️ Attention: Prices may vary depending on the refrigerator model and region. In provincial cities, repairs are usually 20–30% cheaper. Always check the final cost. before starting work.

FAQ: Frequently asked questions about a non-working freezer

The freezer does not freeze, but the light inside is on. What is the problem?

The light indicates that power is being supplied, but the compressor does not start. Reasons:

• Faulty starting relay (clicks, but the compressor does not hum).
• Burnt thermal fuse (relevant for models with No Frost).
• Problems with electronic board (diagnostics needed).

The first thing you can do yourself is to check the relay. It is located on the compressor and is attached to a latch. If you hear a knock when shaking, the relay has burned out.

The refrigerator is new, but the freezer does not freeze well. What should I do?

Possible reasons:

• Transport modeIn some models (for example, Liebherr CNef 4315) you need to manually after delivery. disable the transport mode (instructions in the manual).
• Incorrect installation. If the refrigerator is uneven or too close to the wall (less than 5 cm), air circulation is disrupted.
• Defective compressorIt is rare, but possible. Contact the store for a replacement under warranty.

Check whether the mode is turned on super freezing (if any). data-i="276">Is it possible to use a refrigerator if the freezer does not work?

Can I use the refrigerator if the freezer doesn't work?

Technically yes, but with reservations:

• If it does not work freezer onlyand the main compartment cools, the refrigerator can be used temporarily, but do not store perishable foods in it (meat, fish, milk).
• If the compressor works without stoppingthis leads to its overheating and accelerated wear. It is better to turn off the refrigerator before repair.
• In models. with with one compressor (for example, Atlant MXM-1705) a malfunction of the freezer can lead to spoilage of food in the main compartment.

For temporary for food storage, use cooler bags or ice in thermal containers.

How much does it cost to diagnose a freezer?

The cost of diagnostics depends on the service center:

• Free - if you agree to repairs in the same service.
• 500–1 500 ₽ - if you only need diagnostics (without repairs).
• 2 000–3 000 ₽ - visit of a technician to your home (includes inspection and consultation).

In some services (for example, "RemBytTekhnika" or "Cold Service") diagnostics are included in the cost of repairs. Always clarify this point when calling.

How to extend life freezer after repair?

To avoid repeated breakdowns:

• Defrost the refrigerator every 6-12 months (even if you have No Frost).
• Do not put in the freezer hot foods - this increases the load on the compressor.
• Check sealing rubber once every 3 months. Wipe it with a weak solution of soda (1 tsp per glass of water) for elasticity.
• Use voltage stabilizerif your network has frequent surges.
• Do not overload the freezer. Optimal load: 2/3 of the volume.

For models with No Frost, it is recommended to clean the ventilation holes with a vacuum cleaner once a year (at minimum power).
