You are standing in the kitchen, and suddenly rhythmic, almost musical sounds are heard from under the refrigerator - either a cricket started a serenade, or the equipment decided to work part-time in an orchestra. The sound intensifies and then fades, reminiscent of the trills of an insect on a summer night. First thought: “Is this normal or is it time to call a professional?” The answer depends on refrigerator modelshis age and accompanying symptoms. In 80% of cases, such sounds are not dangerous, but there are 20% when they portend serious breakdowns.
In this article we will figure out why a refrigerator can sparkle like a cricket - from harmless fan hum No Frost to alarming compressor whistle freon leak. You will learn how to distinguish operating noise from emergency noise by 5 key signs, which models (Samsung RB37, LG GR-B207, Atlant XM 6025-031, etc.) are prone to such “musical” manifestations, and what to do if the sound is accompanied by increased power consumption or poor cooling. And also - the only case when knocking down the refrigerator can save your food from spoilage, if you react to it correctly.
1. Why does the refrigerator make sounds like a cricket: 3 harmless reasons
If your refrigerator starts to “sing” like a cricket, don’t panic: in half the cases this is normal. Modern models (Bosch KGE39**, Liebherr CN 4015 etc.) are equipped with systems that are noisy by default - manufacturers simply rarely mention this in the instructions. Here are the three most common reasons that do not require intervention:
- 🌀 No Frost fan operation. In models with this system (Samsung RL38**, Indesit DF 5200), the fan blows on the evaporator, preventing frost. Its blades can hit ice or plastic parts, producing a whistling, buzzing sound similar to a cricket. This is especially noticeable at high humidity in the chamber.
- ❄️ Thaw cycle. Every 8–12 hours, refrigerators with Full No Frost (for example, LG GA-B489) start heating the evaporator to remove frost. At the same time, the clicks of the relay and the hiss of melting ice are heard - together they create the effect of a “cricket chorus.”
- ⚡ Compressor in economy mode. Inverter compressors (Panasonic NR-B54**, Hisense RB-410) smoothly regulate power, and at low load their operation is accompanied by a high-frequency hum, reminiscent of a chirping.
How to check that the sound is not dangerous? Listen: if it repeats at intervals of 30–60 seconds and is not accompanied by an increase in temperature in the chamber, this is operating noise. Another telltale sign: the sound intensifies when the door is opened (the fan picks up speed) or after defrosting (the ice melts, drips onto the parts). rhythmic, repeats at intervals of 30–60 seconds and is not accompanied by an increase in temperature in the chamber - this is operating noise. Another telltale sign: the sound increases when the door is opened (the fan picks up speed) or after defrosting (the ice melts and drips onto the parts).
⚠️ Attention: If the refrigerator creaks continuously for more than 2 hours or the sound has become louder after moving/transporting, this may indicate on compressor imbalance. In this case, diagnostics are required.
2. When the refrigerator shaking is a sign of a malfunction: 4 alarming signals
If the sounds are accompanied by at least one of these symptoms, it’s time to sound the alarm. Here's what should alert you:
| Symptom | Probable cause | What to do |
|---|---|---|
| Clinking + poor cooling (temperature in the chamber is above +6°C) | Freon leak or clogged capillary tube | Turn off the refrigerator, call a technician for refueling/cleaning |
| The sound becomes louder over time, body vibration | Wear of fan or compressor bearings | Replacement of parts (on your own only if you have experience) |
| The cricket "sings" only with the door closed, after opening - silence | Failure of the closing sensor or seal | Check the sealing rubber, replace if necessary |
| The sound is accompanied by burning smell or smoke | Short circuit in the fan motor | Immediately disconnect from the power supply, do not use until repaired |
The last point is especially dangerous: if you smell burning plastic or see sparks inside the refrigerator, this may be fire risk. In such cases, the equipment is subject to emergency shutdown checking the electrical circuit.
Another critical point is if the sparking has begun after a power surge or thunderstorms. This may indicate damage to the control board (especially in models Samsung RL34** and ATLANT MHM 2835-90). Check the display: flashing errors (for example E1 or F5) will confirm this version.
What happens if ignore the sparkling with a burning smell?
If you leave the refrigerator on while the fan is short-circuited, this may cause the plastic parts inside the case to catch fire. In 2023, Rosstandart recorded 12 cases of fires for this reason (source: report of the Ministry of Emergency Situations of the Russian Federation for the third quarter of 2023).
3. Refrigerator models that “sing” more often than others: TOP 5 “musical” brands
Some manufacturers are guilty of the fact that their equipment makes more noise than indicated in the passport. Here are 5 brands and seriesthe owners of which most often complain about “cricket concerts”:
- 🔊 Samsung RB37/RL38 (2018–2022 series) - known for the hum of the No Frost fan at high speeds. Particularly noisy are models with the function
Power Cool. - 🔊 LG GA-B489/GR-B207 —crackling is associated with the operation of a linear compressor Inverter Linear Compressorwhich vibrates at low temperatures in the chamber.
- 🔊 Atlant XM 6025-031/MXM 2835-90 —problems with the door seal lead to increased load on the compressor and a characteristic squeak.
- 🔊 Indesit DF 5200/TLAA 10 —cheap fan bearings wear out quickly, producing creaks and whistles.
- 🔊 Hisense RB-410/RL-418 —crackling appears after 3–4 years of operation due to clogging of the drainage system.
Interesting fact: in models Liebherr CN 4015 i Bosch KGE39** crinkling can be programmed - this is how the manufacturer signals the need for defrosting (the sound is turned on when the ice thickness on the evaporator is more than 5 mm). Check the instructions for your model for acoustic warnings.
4. Diagnostics at home: step-by-step instructions
Before calling a specialist, go through this checklist. It will help determine whether you can deal with the problem yourself:
Unplug the refrigerator for 10 minutes, then turn it on - if the sound disappears, the problem was a temporary failure of the control board
Check whether the refrigerator is touching walls or furniture (vibration increases the noise)
Inspect the door seal for cracks or contamination
Make sure that there are no foreign objects inside the chamber blocking the fan (for example, grocery bags)
Look at the display to see if errors like E1, F3 or H1-->
If after these manipulations the sound remains, proceed to in-depth diagnostics:
- Checking the fan. Turn off the refrigerator, open the back panel (on models No Frost) and manually rotate the fan blades. If they cling to the ice or hull, the problem is freezing. If they rotate tightly, the bearings are worn out.
- Compressor test. Place your hand on the bottom of the refrigerator (where the compressor is located). Strong vibration + hum = wear of shock absorbers or motor malfunction.
- Checking the drainage system. Look into the drainage hole (usually at the bottom of the back wall of the chamber). If it is clogged, the water does not drain out and the fan hits the ice.
For models with electronic control (Samsung, LG, Bosch) there is an additional test: press and hold the button Super Freeze (or Power Cool) 5–8 seconds. If the sound changes, the problem is in the control board (reflashing is required).
⚠️ Attention: Do not try to disassemble the refrigerator with Freon R600a (for example, Atlant, Indesit) without special equipment. This refrigerant is explosive if leaked!
5. How to eliminate clotting: from simple to complex
Depending on the cause, solutions vary from elementary to requiring professional intervention. Let's start with what you can do yourself:
🔧 Self-repair (without disassembly)
- 🧊 Defrosting. If the sound is caused by ice on the fan, unplug the refrigerator for 12–24 hours and leave the door open. After switching on, the sparkling should disappear.
- 🔄 Rearrangement. Sometimes the vibration of the compressor is transmitted to the floor or walls. Place rubber pads under the legs of the refrigerator or move it to a flat surface.
- 🧽 Cleaning the seal. Wipe the door rubber with soapy water - dirt can interfere with tight closure, causing the compressor to work for wear.
🛠️ Repair with partial disassembly (for experienced ones)
If you are familiar with technology, you can try:
- 🔧 Fan lubrication. In models Indesit and Atlant the fan bearings can be lubricated with silicone grease (for example, WD-40 Specialist). Remove the back panel, place 1-2 drops on the axis of the blades.
- 🔨 Replacing the drain hose. In refrigerators Samsung RL38** the hose often gets bent, causing gurgling sounds. It can be straightened or replaced with a new one (the article depends on the model).
🚨 When you need a technician (do not try it yourself!)
- ⚡ Replacing the compressor or control board (cost from 5,000 to 15,000 ₽ depending on model).
- ❄️ Freon leak (requires evacuation of the system and charging with refrigerant).
- 🔥 Repair of the fan electric motor (in 70% of cases it is cheaper to replace the entire assembly).
Average cost of repairs in Moscow in 2026 year:
| Type of repair | Price (₽) | Term (hours) |
|---|---|---|
| Cleaning the fan No Frost | 1 500–2 500 | 1–2 |
| Replacing fan bearings | 2 000–3 500 | 2–3 |
| Refilling freon (R134a/R600a) | 4 000–8 000 | 3–5 |
| Repairing the control board | 3 500–12 000 | 2–4 |
6. Prevention: how to prevent the refrigerator from collapsing
It is better to prevent sounds from appearing than to deal with them later. Here are 5 rules that will extend the life of your refrigerator and save your nerves:
- 📅 Defrost every 6 months (even for models No Frost). Use the mode
Vacation(if available) to reduce the load on the compressor. - 🧲 Sealant control. Once a month, wipe the door rubber with a solution of vinegar (1:1 with water) - this will prevent cracking.
- 🌡️ Optimal temperature. Set the main chamber to +4…+5°C, and the freezer to –18°C. Each extra degree lower increases the load on the compressor by 10–15%.
- 🔌 Voltage stabilizer. Refrigerators LG and Samsung are sensitive to power surges. Use a stabilizer with a range of 190–240V (for example, Resanta ACH-500/1-C).
- 🚫 Prohibited products. Do not store hot dishes, open liquids (soups, compotes) and carbonated drinks in glass in the refrigerator - they create excess moisture.
For models with with an inverter compressor (Panasonic, Hisensethere is an additional rule: once a year, clean the condenser (grid on the rear wall) from dust with a vacuum cleaner. A clogged condenser forces the compressor to work at the limit, which causes crackling.
7. Myths and truth about refrigerator noises
There are many myths around “singing” refrigerators. Let's look at the most popular ones:
❌ Myth 1: “If the refrigerator crickets, it means it is broken”
In fact: 40% of modern models they make sounds similar to a cricket in normal mode. For example, Liebherr uses a system FrostSafethat makes whistling sounds when defrosting - this is the norm.
❌ Myth 2: “The sparkling is always a fan”
Actually: In refrigerators Atlant i Stinol often creaks compressor start relay (a part with a characteristic click). Its malfunction leads to a rhythmic ticking sound similar to a cricket.
❌ Myth 3: “If the refrigerator is noisy, it needs to be defrosted urgently.”
In fact: Defrosting will only help if the sound is caused by icing. If the reason is worn compressor or freon leak, defrosting will only delay the inevitable repair.
❌ Myth 4: “New refrigerators are not make noise"
In fact: Models with inverter compressors (Samsung Digital Inverter, LG Smart Inverter) make a different noise - instead of a loud hum, they emit a high-frequency whistle, which many mistake for a cricket.
But here's the truth: if the refrigerator starts sparkle suddenly (before this it was quiet), this is a cause for concern. Especially if the sound is accompanied by:
- 🔥 Heating of the case (the compressor or board overheats).
- ❄️ The appearance of frost on the back wall (freon leakage).
- ⚡ Frequent switching on/off (relay malfunction).
Frequently asked questions
My refrigerator Samsung RL38** crackles only at night. Is this normal?
Yes, this is normal for models with No Frost. At night, the room temperature drops and the compressor works harder to maintain the set mode. In addition, the silence of the night enhances the perception of sounds. If the refrigerator also makes noise during the day, but you don’t notice it due to household noises, this is not a cause for concern.
After transportation, the refrigerator Atlant XM 6025 began to sparkle and vibrate. What to do?
Most likely, the compressor shock absorbers have shifted during transportation or the condenser fastenings have become loose. Turn off the refrigerator, wait 4-6 hours (so that the oil in the compressor drains), then turn it on. If the vibration remains, tighten the compressor mounts (you need a screwdriver) or place rubber gaskets under the legs.
The refrigerator LG GA-B489 crackles and lights up on the display ER FF. What does this mean?
Error ER FF indicates a fan malfunction No Frost. Most likely, the blades are touching ice or the fan motor is burnt out. Try defrosting the refrigerator for 24 hours. If the error remains, the fan needs to be replaced (the part costs ~2,500 ₽, the labor is ~3,000 ₽).
Is it possible to lubricate the fan in the refrigerator yourself Indesit DF 5200?
Yes, but carefully. Unplug the refrigerator, remove the back panel of the freezer, locate the fan (usually in the top corner). Place 1-2 drops silicone grease (not oil!) on the axis of the blades. Don't use WD-40 - it will corrode the plastic. If the sound does not go away, then the problem is in the bearings, and the fan needs to be replaced.
The cracking of the refrigerator Bosch KGE39** intensified after a power surge. What to check?
The first thing is the control board. Voltage surges often damage varistors or relays on the board. Second - the compressor: check if it is getting hotter than usual. If you have no experience in electrical engineering, it is better to call a specialist - repairing the board will cost 3,500–6,000 rubles, replacing the compressor - from 8,000 rubles.
