The refrigerator stopped freezing: 12 reasons and step-by-step repairs at home

Have you opened the refrigerator, but the food has melted, there is no frost on the back wall, and the motor runs without stopping or is completely silent? The situation is familiar to many: the equipment turns on, the lights are on, but The freezer is not freezingand in the main compartment, instead of coolness, there is room temperature. Don’t rush to call a technician: in 60% of cases, the problem can be fixed on your own in 10-30 minutes.

In this article we will look at why the refrigerator stopped freezing - from a simple settings failure to serious compressor breakdowns. You will learn how all possible reasons, for which the refrigerator stopped freezing - from a banal settings failure to serious compressor breakdowns. You will learn how to diagnose a malfunction using improvised means, what manipulations are safe to do at home, and when it is better to immediately disconnect the equipment from the network. Let us separately focus on hidden symptoms of freon leakwhich are often ignored until critical damage to the system.

The material is suitable for any refrigerator brands: Atlant, Samsung, LG, Indesit, Bosch, Beko and others. The instructions are universal for models with No Frostdrip system and static cooling. If your unit is older than 10 years, pay attention to the block about wear and tear of parts.

1. First steps: what to check before repair

Before disassembling the refrigerator or looking for spare parts, eliminate external factors that do not require intervention in the design. Start with the most obvious:

• 🔌 Power and socket: connect another device (for example, a hair dryer) to the same outlet. If it doesn't work, the problem is with the wiring, not the refrigerator. Check the machine in the panel.
• ❄️ Cooling mode: the mode "Vacation" or "Eco"may have been accidentally activated, which turns off the freezer. On models Samsung and LG this may be a button Fridge or Vacation.
• 📏 Closing the door: even a small gap of 2-3 mm breaks the seal. Check if there is a foreign object obstructing the seal (for example, crumbs or sticky packaging).
• 🌡️ Room temperature: if the refrigerator is standing next to a radiator or in the sun, the compressor may not cope. The norm for work is +16…+32°C.

If everything is in order with external conditions, proceed to diagnosing internal systems. But first unplug the refrigerator this will protect you from electric shock when inspecting parts. Don't forget to remove all the food so that it doesn't spoil during the check.

2. The compressor works, but does not freeze: 4 reasons

The engine hums, but there is no cold? This is a classic symptom of problems with refrigerant or circulation system. Let's consider possible scenarios:

2.1. Freon leak

If the refrigerator stops freezing after moving, mechanical cleaning or a sharp blow, there is a 95% probability that a freon leak is to blame. The refrigerant leaks through microcracks in the tubes and the system stops cooling. Signs:

• 🔍 The compressor works without stopping, but the temperature does not drop.
• 🧊 There is no frost on the back wall (even in freezer).
• 💨 The condenser (grid at the back) is cold, although it should heat up.

It is impossible to fix the leak on your own - you need a special tool for soldering the tubes and refilling the freon. But you can preliminarily confirm the diagnosis:

1. Disconnect the refrigerator and move it away from the wall.
2. Inspect the tubes for oil stains (freon comes out along with the oil).
3. Check the soldering points - cracks often appear there.

What to do if you find a leak?

Do not turn on the refrigerator - this may lead to overheating of the compressor. Contact the service, indicating the model (located on a sticker inside the chamber or on the back). Average cost of repair: 3,500–8,000 ₽ (depending on the volume of freon and the complexity of soldering).

2.2. Clogged capillary tube

Over time, particles of oil, rust or moisture accumulate in the system, which clog thin tubes. The compressor is running, but the refrigerant is not circulating. Symptoms:

• 🔊 The motor hums louder than usual.
• ⏳ The refrigerator cools for a very long time (for example, 6-8 hours instead of 1-2).
• 🌡️ The temperature in the freezer and the main compartment is equally high.

For cleaning you need hydraulic press or pneumatic gun, so this cannot be done at home. However, you can try defrost the refrigerator for 24 hours - sometimes this helps with minor blockages.

2.3. Failure of the thermostat (thermostat)

The thermostat is responsible for turning the compressor on/off. If it breaks, the motor either runs continuously or does not start at all. How to check:

1. Find the thermostat (usually it is hidden under a plastic panel inside the chamber).
2. Remove the protective casing and inspect the contacts for oxidation.
3. Ring the part with a multimeter in resistance testing mode. At room temperature, the resistance should be 0 Ohm (contacts closed).

If the thermostat is faulty, it must be replaced. For models Atlant and Indesit universal thermostats are suitable K-59 or Danfoss 077B6 (cost - 800–1,500 rubles).

2.4. Faulty start-up relay

The relay starts the compressor and protects it from overheating. If a motor breaks down, it can:

• 🔄 Turn on for 5-10 seconds and turn off.
• 🔇 Not start at all (no characteristic hum).
• 💥 Make clicks when trying to start.

To check relay:

1. Remove it from the compressor (usually it is attached to the motor).
2. Shake the part - if you hear a knock, this is a sign of mechanical wear.
3. Ring the coil with a multimeter: there should be resistance 20–40 Ohm.

Replacing the relay will cost 500–1,200 ₽. For refrigerators Samsung and LG relays RLS-4 or DANFOSS 103N0020.

3 are often suitable. The compressor does not turn on: 3 critical breakdowns

If the motor does not hum, does not heat up or vibrate, the problem may be electrical circuit or a mechanical breakdown of the compressor. Let's consider the main reasons:

3.1. The compressor burned out

This is the most expensive breakdown - replacing the motor will cost 5,000–12,000 rubles (depending on the model). Signs:

• 🔌 The refrigerator does not respond at all when plugged in.
• 💥 When you try to start, the automatic switch in the panel is triggered.
• 🌡️ The compressor housing is excessively hot (more 70°C).

Check the compressor with a multimeter:

1. Turn off the refrigerator and discharge the capacitor (short-circuit it with a screwdriver with an insulated handle).
2. Remove the cover from the compressor terminals.
3. Ring the windings: the resistance between the contacts should be 10–30 Ohm.

If the device shows 0 Ohm (short circuit) or ∞ (break), the compressor is faulty.

3.2. Failure of the electronic control unit

In modern refrigerators (for example, Samsung RL-60 or LG GA-B489) an electronic board is responsible for the operation of the compressor. If it fails:

• 📛 Errors appear on the display (for example, E1, F5 or dH).
• 🔄 The compressor turns on chaotically or does not respond to commands.
• 🎛️ Buttons do not work controls.

Independent repair of the board is possible if you have experience in soldering microcircuits. In other cases, it is better to order a new one (price - 2,000–5,000 rubles) or give it for reflashing (1,500–3,000 rubles).

3.3. compressor

If the compressor does not burn out, but does not start, a break in the internal winding is possible. This happens due to:

• ⚡ Power surges in the network.
• 🔄 Frequent switching on/off (for example, with a faulty thermostat).
• 🕒 Natural wear (after 10-15 years of operation).

Diagnostics:

1. Ring the compressor windings (as described above).
2. If there is resistance between any contacts ∞, this is an open circuit.
3. Check the circuit for a short to the case: one multimeter probe on the metal body of the compressor, the second - on each contact in turn. The resistance should be ∞.

4. Problems with the No Frost system: why the upper chamber does not freeze

Refrigerators with No Frost (for example, Bosch KAN92VI20 or Beko GNE114620X) have additional components that may fail if the freezer does not freeze and the fan does not. is working, check:

4.1. Fan malfunction

The fan distributes cold air to the chambers. If it is broken:

• 🌬️ It’s cold in the freezer, but not in the main compartment.
• 🔇 There is no characteristic air noise when the door is opened.
• ❄️ Ice forms on the back wall of the freezer (the fan does not blow through the evaporator).

How to check:

1. Unplug the refrigerator and remove the back panel of the freezer.
2. Find the fan (usually it is located behind the evaporator).
3. Try to turn the blades by hand - if they do not rotate, the problem is in the bearing.
4. Test the winding with a multimeter: the resistance should be 200–500 Ohm.

Replacement of the fan will cost 1,000–2,500 rubles. For models Samsung a fan is suitable DA97-06013A.

4.2. Breakdown of the defrost heater

In systems No Frost there is a heating element that melts the ice on the evaporator. If it burns out:

• 🧊 The evaporator becomes covered with ice (visible after removing the back panel of the freezer).
• 🌡️ The temperature in the freezer rises to 0…-5°C.
• 🔄 The refrigerator often turns on and off.

Check:

1. Get to the heater (it is located under the evaporator).
2. Test it with a multimeter: there should be resistance 20–40 Ohm.
3. If the device shows ∞, the heating element is burnt out and requires replacement.

4.3. Defrost timer malfunction

The timer controls the defrost cycle. breakdown:

• ⏳ The refrigerator works without shutting down for 6-12 hours.
• 🧊 The evaporator is covered with a thick layer of ice.
• 🌡️ The temperature in the freezer is unstable (either -18°C, then -5°C).

To check the timer:

1. Locate it (usually it is located next to the compressor or on the control board).
2. Turn the timer knob clockwise until it clicks - if the refrigerator does not go into defrost mode, the part is faulty.

5. Mechanical breakdowns: door, seal, sensors

Sometimes the problem lies not in the electrical system, but in mechanical parts. yourself without special tools.

5.1. Wear of the door seal

The rubber seal loses its elasticity over time, and warm air penetrates into the chamber. Signs:

• 🌬️ Condensation accumulates on the walls of the refrigerator.
• 🧊 The compressor works almost without stopping.
• 📏 A gap of more than 2 mm is visible between the door and the body.

How to restore the seal:

1. Warm the rubber with a hairdryer (temperature 50–60°C) - this will restore its elasticity.
2. If there are cracks, seal them with silicone sealant.
3. For a complete replacement, select a seal according to the model of the refrigerator (cost - 800–2,000 ₽).

5.2. Temperature sensor failure

The sensor transmits temperature data to the control board. If it is lying:

• 🌡️ The refrigerator freezes too much or weakly.
• 📛 On the display shows an incorrect temperature (for example, -18°C, although in the freezer 0°C).
• 🔄 The compressor turns on randomly.

Check:

1. Find the sensor (usually it is located on the back wall of the chamber).
2. Measure its resistance with a multimeter at room temperature. For most sensors it should be 4–7 kOhm.
3. Place the sensor in a glass of cold water - the resistance should increase.

5.3. Warp of the door.

If the door hangs crookedly, the seal does not fit tightly. Reasons:

• 🔧 The hinges are loose.
• 🚪 The refrigerator is standing on an uneven surface.
• 💥 There was a mechanical impact (for example, blow).

How to adjust:

1. Check the level of the refrigerator (use a building level).
2. Tighten the hinges with a screwdriver or wrench (usually needed cross screwdriver; wrench 10; data-i="269">Some breakdowns require professional equipment and experience. Here are situations in which or 10mm wrench).
3. If the hinges are bent, replace them (cost: 300–800 RUR per piece).

6. When to call a professional: 3 cases when amateur activity is dangerous

Some breakdowns require professional equipment and experience. Here are the situations in which you should not repair the refrigerator yourself:

Also contact a specialist, if:

• 🔥 The refrigerator sparks or smokes when turned on.
• 💥 Triggers automatic machine in the panel when you try to start.
• 🧪 You you suspect a freon leak, but cannot find the location of the damage.

7. Prevention: how to avoid breakdowns

To make the refrigerator last longer, follow simple rules:

• 🧹 Defrosting: carry it out every 6 months (even for No Frost) Use plastic scraperto avoid damaging the walls.
• 🔌 Network: connect the refrigerator. through voltage stabilizer (especially in rural areas or old houses).
• 🧴 Caring for the seal: wipe the elastic band soap solution once a month and lubricate silicone grease.
• 📦 Location products: do not place hot dishes and do not stuff the chamber to capacity - this disrupts air circulation.
• ☀️ Installation location: keep the refrigerator away from direct sunlight and heating devices (minimum distance - 50 cm).

For models with No Frost additionally:

• 🌬️ Not block the ventilation holes with products.
• 🧊 Once a year, clean the drainage hole (use a cotton swab or a syringe).

FAQ: Frequently asked questions about refrigerators that do not freeze

❓ The refrigerator does not freeze, but the light is on - what does this mean?

This indicates problem with compressor, thermostat or electronic board. First, check if the motor is working (put your hand on the body - it should vibrate). data-i="324">or thermostat or start protection relay. If the motor is silent, the problem is compressor or power.

❓ Is it possible to repair the refrigerator yourself if it is under warranty?

No. Any independent intervention (even replacing the light bulb) voids the warrantyContact the brand’s service center - repairs will be free. if the breakdown is not your fault. Exception: replacing the seal or adjusting the hinges (this is not considered interference with the design).

❓ How much does it cost to charge freon in the refrigerator?

The cost depends on the type of refrigerant and volume systems:

• R-134a (modern models) - 3,500–5,000 ₽;
• R-600a (isobutane, used in Atlant, Indesit) — 4 000–6 000 ₽;
• R-12 (old Soviet refrigerators) - 5,000–8,000 ₽ (due to shortage refrigerant).

The price usually includes diagnosing leaks, soldering pipes and checking the system for leaks.

❓ Why does the refrigerator freeze but does not turn off?

This is a sign that the compressor is wearing out. Possible reasons:

• 🧊 Freon leak — the motor is trying to compensate for the lack of refrigerant;
• 🌡️ Faulty thermostat —does not give a shutdown command;
• 🔥 Clogged capillary tube —the compressor cannot pump freon;
• 🚪 Problems with the seal —warm air enters the chamber.

Urgently disconnect the refrigerator from the network and call a technician - continuous operation of the compressor leads to its overheating and breakdown.

❓ How long can food be stored if the refrigerator does not freeze?

The timing depends on the type of food and the room temperature:

Product	Room temperature	Maximum shelf life
Meat, fish	+20°C	2–4 hours
Dairy products	+20°C	4–6 hours
Vegetables, fruits	+20°C	6–12 hours
Ready meals	+10…+15°C	8–12 hours

To extend shelf life, wrap food foil or put it in thermal bag so ice.

⚠️ Attention: If your refrigerator is over 15 years old, repair may not be economically feasible. The cost of replacing a compressor or control board sometimes exceeds 50% of the price of a new unit. Before repairing, check with the technician how long the refrigerator will last after repair.
