You are standing in the kitchen, and suddenly the refrigerator begins to make strange noises gurgling sounds as if water is boiling inside it or liquid is overflowing. First thought: “Is this normal or is it time to call a professional?” The answer depends on many factors - from the model of equipment to operating conditions. In 90% of cases, gurgling is not dangerous, but in 10% it can signal an imminent breakdown.
In this article we will analyze all possible causes gurgling sounds - from harmless (freon circulation) to critical (refrigerant leakage). You will learn how to distinguish operating noise from a malfunction, when you can do it yourself, and when professional repair is required. We also collected unique data on models 2020–2026where gurgling occurs more often due to design features.
Not hurry to panic: modern refrigerators (especially those with No Frostsystem) often “talk” louder than old Soviet models. But if the sound is accompanied by other symptoms - increased temperature in the chamber, puddles under the bottom or the constant hum of the compressor - this is a reason to act.
1. Normal causes of gurgling: when there is no need to worry
Most gurgling sounds are associated with circulation of refrigerant (freon) through the system pipes. This is a natural process, especially noticeable in new refrigerators or after defrosting. This is why it occurs:
- 🔄 Freon movement through capillary tubes. When the compressor is turned on, the liquid refrigerant begins to move, making sounds similar to water pouring.
- ❄️ Evaporator defrosting. In models with No Frost melt water flows through the drainage system, which may be accompanied by gurgling (especially in refrigerators Samsung RB37 i LG GC-B24).
- 🌡️ Thermoregulation. When the temperature in the chamber changes (for example, after loading warm products), the compressor is activated, and freon begins to circulate more intensely.
How to distinguish normal gurgling from a breakdown? Pay attention to periodicity and related symptoms:
- ✅ The sound appears periodically (for example, once every 1-2 hours) and lasts no longer than 1-2 minutes.
- ✅ Refrigerator maintains the set temperature (check thermometer).
- ✅ There is no puddle at the bottom, and ice does not form on the back wall.
If all three conditions are met, sounds most likely not dangerousBut there is a nuance: in refrigerators with inverter compressor (for example, Bosch KIN86** or Liebert HFC-210) gurgling may be louder due to smooth power control. This is not a defect, but a design feature.
⚠️ Attention: If gurgling is accompanied constant humming of the compressor (without pauses), this may indicate overload system or thermostat malfunctionIn this case, diagnostics are required.
2. Gurgling due to the drainage system: when water is to blame
One of the most common reasons is problems with drainage of melt waterIn refrigerators with drip defrosting or No Frost condensate flows through special channels into the pan, where it evaporates. If the drainage is clogged, water accumulates and makes gurgling sounds when moving.
How to check the drainage system:
- Unplug the refrigerator and empty the bottom shelf (in most models the drainage hole is located at the back, under the vegetable drawer).
- Take thin wire or a special brush (come complete with some models, for example Indesit DF 4180) and carefully clean the hole.
- Rinse the drainage warm water and soda (1 tablespoon per 200 ml) using a syringe or syringe.
☑️ Cleaning the drainage system
If after cleaning, the gurgling does not disappear, check:
- 💧 The water level in the pan. Normally, it should be almost dry. If liquid accumulates there, it may be is clogged. evaporation channel (disassembly of the rear panel is required).
- 🔧 The position of the refrigerator. If it is standing is uneven, water can accumulate in one corner, creating sounds when moving.
In models with No Frost (for example Samsung RL62** or ATLANT XM. 6025) gurgling may increase during automatic defrost (usually every 8-12 hours). It is normal if the sound disappears after 10-15 minutes.
3. Problems with refrigerant: when gurgling is dangerous
If gurgling sounds are accompanied by constant, accompanied poor cooling or freezing of the rear wall - this may indicate freon leak or clogged capillary tube. Let's consider both cases.
3.1. Refrigerant leak
Signs of a freon leak:
- ❄️ Refrigerator does not freeze well, but the compressor works without stopping.
- 🔊 Gurgling continuous, similar to “boiling” (sound of bubbles in tubes).
- 💨 Appears on the back wall oil (freon circulates along with the compressor oil).
Leakage most often occurs in places soldering of tubes or because corrosion of aluminum parts (relevant for refrigerators older than 7-10 years). It is impossible to eliminate it yourself - it requires refilling freon soldering of the damaged area.
⚠️ Attention: Freon no odor, but its leak can lead to compressor overheating and complete failure of the refrigerator. If you suspect a leak - immediately turn off the equipment and call a specialist.
3.2. capillary tube
The capillary tube is a thin channel through which freon enters the evaporator. If it becomes clogged (for example, due to oil oxidation or moisture ingress), the refrigerant begins to “gurgle”, trying to push through the obstacle.
Symptoms blockage:
- 🌡️ The temperature in the refrigerator compartment rises, but in the freezer remains normal (or vice versa).
- 🔊 The sound is similar to "squelching" with a metallic tint.
- ⏳ The compressor runs longer than usual (on/off cycles are lengthened).
The blockage is removed flushing the system or replacing the capillary tube. This cannot be done at home - special equipment is required for evacuation and refilling freon.
| Cause of gurgling | Associated symptoms | Can I fix it myself? |
|---|---|---|
| Freon circulation | Short-term sounds, normal temperature | Yes (no need to do anything) |
| Clogged drainage | Water under the drawers, gurgling when the door is opened | Yes (cleaning the drainage) |
| Freon leak | Poor cooling, oil on the tubes, continuous gurgling | No (a master is required) |
| Clogged capillary tube | Uneven cooling, long compressor cycles | No (a master is required) |
| Compressor malfunction | Loud humming + gurgling, case overheating | No (replacement required) |
4. Gurgling in refrigerators with No Frost: system features
Refrigerators with No Frost (for example, LG GA-B489, Samsung RB3000, ATLANT MHM 2835) gurgle more often due to automatic defrosting. They are equipped with fanwhich distributes cold air, and heating element (heating element) that thaws ice on the evaporator.
During defrosting (usually every 8-12 hours) you can hear:
- 💦 Gurgling water —this is melt water flowing down the drainage system.
- 🌀 Fan noise —it turns on to evenly distribute the temperature.
- 🔥 Slight crackling —the heating element heats up (normal for models with Full No Frost).
If gurgling in No Frostthe refrigerator has become louder than usual, check:
- Condition door seal. A worn rubber band allows warm air to pass through, causing the defrosting system to work more often.
- Loading food. If the refrigerator is full, the fan has to work harder, which increases the noise.
- Temperature conditionsin hot weather or when installed next to the stove No Frost turns on defrosting. more often.
In models. c Low Frost (for example, Beko CN 325120) gurgling may be due to freezing of the evaporator. If ice appears on the back wall of the refrigerator compartment, it is required manual defrosting (despite the presence of the system No Frost c). freezer).
5. Gurgling after defrosting or transportation
If the refrigerator began to gurgle immediately after defrosting or transportation, this is due to two factors:
- Redistribution of freon and oil. During prolonged downtime or tilting of the equipment, the refrigerant and compressor oil are mixed after switching on. zone, which is accompanied by gurgling (can last up to 1–2 days).
- Accumulation of condensateAfter defrosting, water remains in the drainage system, which flows into the pan with a characteristic sound.
What to do:
- ⏳ Wait 24-48 hours. If the gurgling does not disappear, look for other reasons.
- 📏 Check the level of the refrigerator. It should stand. strictly horizontal (use a building level). accumulation of water and increased gurgling.
- 🔌 Make sure the voltage is stable.Electricity surges can cause incorrect operation of the compressor and, as a result, unusual sounds.
⚠️ Attention: If the refrigerator transported lying down (for example, in a car), before turning it on you need maintain in an upright position for 4–6 hoursOtherwise, oil from the compressor will get into the tubes, which will lead to hydraulic shock and breakdown.
What happens if you turn on the refrigerator immediately after transportation?
If you do not wait the recommended time, the oil from the compressor may clog the capillary tube. This will lead to its failure. In 80% of cases, such repairs cost 50–70% of the cost of a new refrigerator. motor overheating and its failure. In 80% of cases, such repairs cost 50–70% of the cost of a new refrigerator.
6. Gurgling in the freezer: individual reasons. data-i="290">If gurgling sounds come from
If gurgling sounds come from the freezer compartment, this may be due to:
- ❄️ Freezing of the evaporator. The temperature in the freezer is lower, so the ice builds up more intensely. During automatic defrosting, melt water flows out with a characteristic pattern. gurgling.
- 🔄 Switching valve operation (in refrigerators with one compressor for two chambers, for example, ATLANT MHM 1843). data-i="297">Operation of the switching valve
- 💧 Clogged freezer drainage. Unlike the refrigerator compartment, the freezer drainage hole becomes clogged less often, but cleaning it requires disassembling the rear panel.
How to check the freezer:
- Defrost the chamber and inspect evaporator (the ribbed panel on the back). If it is covered with ice, defrosting or replacement is required. heating element (in models with No Frost).
- Listen does the sound change? when switching modes. For example, in refrigerators Indesit BIAA 13 the valve makes a click and a short gurgle when changing the chamber.
If the freezer stopped freezingbut the gurgling persists, this is a sign freon leakage in freezing circuit or temperature regulator failure.
7. When to call a technician: 5 critical symptoms
You can fix it yourself only clogged drainage or incorrect installation. gurgling is accompanied by at least one of these signs, professional help is required:
- ❌ The refrigerator does not cool (temperature in the chambers is above +8°C).
- ❌ The compressor runs without stopping (no on/off cycles).
- ❌ Oil is visible on the back wall or tubes (a sign of freon leakage).
- ❌ There is a smell of burning or plastic (may indicate overheating compressor).
- ❌ Gurgling is accompanied by vibration or knocking (compressor failure is possible).
The cost of repairs depends on the cause:
| Problem | Average cost of repair (2026) | Time frame |
|---|---|---|
| Drainage cleaning | 800–1 500 ₽ | 30–60 minutes |
| Refilling freon | 3 500–6 000 ₽ | 2–4 hours |
| Replacement of the capillary tube | 4 000–7 500 ₽ | 3–5 hours |
| Compressor repair | 5 000–12 000 ₽ | 4–6 hours |
⚠️ Attention: Prices and terms may vary depending on the region and model of the refrigerator. For example, repair built-in refrigerators (for example, Liebherr ICBN 3366) costs 20–30% more due to the difficulty of accessing parts.
Before calling the technician, write down the refrigerator model (located on the sticker inside the camera or on the back) and describe the symptoms as accurately as possible. This will help diagnose the problem over the phone and save time.
FAQ: Frequently asked questions about gurgling in the refrigerator
My refrigerator gurgles only at night. Is this normal?
Yes, this is normal. At night, the room is quieter, so the sounds of freon circulation or drainage become more noticeable. Also at night, the compressor may turn on more often due to lowering the temperature in the room (the refrigerator strives to maintain the set mode). If you don’t hear any sounds during the day, there is nothing to worry about.
The refrigerator gurgles and does not freeze. What to do?
This is a sign freon leakage or compressor breakdown. Immediately unplug the refrigerator and call a technician. Continuing to operate in this condition can lead to motor burnout.
After defrosting, the refrigerator gurgles and does not turn off. What's the matter?
Probable reasons:
- Incorrect defrosting (for example, they scraped the ice with a knife and damaged the evaporator).
- Clogged capillary tube due to moisture entering during defrosting.
- Failure of the thermostat (the refrigerator “does not understand” that it has already reached the desired temperature).
A technician needs diagnostics.
In the freezer gurgles, but the refrigerator is quiet. Is this a breakdown?
Not necessarily. In the freezer, gurgling may be due to:
- Automatic defrosting (in models with No Frost).
- Operation switching valve (if the refrigerator is single-compressor).
- Accumulation of condensate in the freezer drain.
If the freezer is operating normally (temperature −18°C and below), the sounds are not dangerous.
The refrigerator gurgles and smells like plastic. What is it?
The smell of plastic +. gurgling - critical symptom. This may indicate:
- Overheating of the compressor (risk of fire!).
- Melting of wire insulation (for example, due to a short short circuit).
- Oil leakage from the compressor (if oil gets on heated parts).
Immediately unplug the refrigerator and do not turn it on until the technician arrives!
