An annoying creaking refrigerator can turn quiet evenings into torture, disturbing the peace of all apartment residents. Often this sound appears suddenly, causing the owner to think about a serious breakdown or the need for expensive repairs. However, in most cases, the problem lies in banal friction of parts, which can be eliminated yourself without calling a technician.
Before looking for tools, you need to accurately determine the source of the unpleasant sound. Refrigeration equipment makes sounds of a different nature: humming, gurgling, clicking and, of course, creaking. Localization of the source is the first and most important step to silence. If the sound comes from below, most likely the problem is in the compressor or its mounting, and if from above, you should check the fan or evaporator.
It is important to understand that not all sounds indicate a malfunction. Some models Indesit or Stinol may squeak slightly when the plastic expands due to temperature changes. However, if the sound becomes constant and loud, it cannot be ignored. Prolonged friction without lubrication leads to accelerated wear of moving parts and can damage the unit.
Diagnostics of the sound source
To effectively eliminate the problem, you need to act methodically. First, listen at what point in the operation of the equipment the creaking appears. This can happen at startup compressor, while the system is running No Frost or when the door is opened. Sometimes extraneous noise occurs only during certain defrosting cycles.
Try to gently press on different parts of the housing. If, when you press the side wall or top panel, the sound changes or disappears, it means that the case itself or poorly secured trim elements are resonating. In such cases, it is often enough to simply tighten the fastening screws or install an additional seal.
If the creaking is clearly mechanical and comes from the inside of the unit, a more in-depth diagnosis will be required. The most common cause of creaking in modern models is drying out of the lubricant in the fan bushings or compressor suspension. Do not rush to disassemble the entire refrigerator, start with a visual inspection of the accessible components.
- 🔍 Listen to the nature of the sound: a rhythmic squeak often indicates the fan, and an intermittent squeak often indicates the compressor.
- 👂 Place your ear against the back wall (being careful) to understand where exactly the sound originated.
- 👐 Gently rock the body: if the legs are unstable, vibration can cause friction between the tubes and metal parts.
Elimination of vibration of the body and tubes
Often the cause of noise is banal vibration. A refrigerator is a massive appliance, and if it is not installed level, the running motor will cause the entire body to vibrate. These vibrations lead to the fact that copper tubes they begin to rub against each other or against the walls of the cabinet. Fixing this is quite simple, but care is required.
Check the installation of the unit. Use a building level or simply judge by eye whether the refrigerator is level. The legs should be twisted so that the body is stable and does not wobble with a slight push. If the refrigerator is standing crookedly, the compressor works with increased load, which increases vibration and provokes the appearance of squeaks in places where parts come into contact.
⚠️ Attention: Before moving the refrigerator, be sure to unplug it and let it stand for at least 2-3 hours. This is necessary to allow the refrigerant and oil to drain to the bottom of the system, otherwise the compressor may be damaged when restarting.
If everything is in order with the installation, inspect the area around the motor at the back. The tubes may touch due to movement during transportation. Gently, without sudden movements, try to separate them with your hands. Pieces of porous rubber are ideal for isolating touch points. or special vibration-isolating material.
Sometimes the tubes are attached to the body with plastic clips, which dry out over time and begin to creak. In this case, regular lubrication or replacement of fasteners will help. Also check that the back wall of the refrigerator does not touch the furniture or the wall - even a minimum gap of 5-7 centimeters is necessary for normal air circulation and absence of resonance.
Repair and lubrication of the compressor
The compressor is the heart of the refrigerator, and it is it that most often becomes the source of noise. Inside the black metal tank is a motor suspended by springs. If these springs rust or become dislodged, they begin to rub against the body, producing a nasty metallic squeak. Internal valves can also be a source of sound, but repairing them at home is impossible.
To access the compressor, you will need to remove the back panel at the bottom of the refrigerator. It is usually secured with several screws or latches. Be careful: there may be dust and cobwebs inside, which are best removed immediately with a vacuum cleaner. Dust on a hot compressor not only smells when heated, but also impairs heat transfer.
Inspect the motor suspension. If the springs are rusty, they can be carefully lubricated. To do this, it is best to use WD-40 to clean off rust, and then apply a thick lubricant, for example, litol or graphite lubricant. Liquid oils are not suitable here, as they will quickly drain and stop working.
| Lubricant type | Temperature range | Application | Durability |
|---|---|---|---|
| Litol-24 | from -40 to +120°C | Springs, bushings | High |
| WD-40 | from -50 to +100°C | For cleaning only | Low (evaporates) |
| Silicone grease | from -40 to +200°C | Rubbers, plastic | Medium |
| Graphite lubricant | up to +300°C | Friction metal pairs | Very high |
If the creaking comes from inside the most sealed compressor casing, then, alas, this is a sign of wear on the internal mechanical parts. In this case, only replacing the unit with a new one will help. However, it often happens that it is the external fastening elements that make noise, and their maintenance returns silence.
☑️ Compressor diagnostics
Maintenance of the No Frost system and fan
In refrigerators with a system No Frost the fan is responsible for air circulation. Over time, its bearing or bushing loses lubrication, and the device begins to creak or buzz unpleasantly. This sound is usually heard at the top of the freezer or behind the back wall of the refrigerator compartment.
To reach the fan, you often have to defrost the refrigerator completely (at least 24 hours), as it may be hidden behind a layer of ice and a plastic panel. Once defrosted, remove the panel and locate the fan. Check whether ice or foreign objects are interfering with it.
If the blades are clean, but when rotating by hand you feel a tight movement or hear a creaking sound, lubrication is necessary. Remove the fan and drop a couple of drops of sewing machine oil or special bearing grease into the center of the axle. Sleeve bearing is especially sensitive to the quality of the lubricant, so you should not skimp on it.
⚠️ Attention: Do not use food-grade vegetable oil butter! It thickens over time, turns into a sticky mass and finally jams the fan, which will lead to overheating of the motor.
Also check the integrity of the blades. If one of them is cracked or deformed, there will be an imbalance that will cause vibration and noise. In this case, it is easier to replace the part with a new one, choosing an analogue in size and connection connector.
How to understand that the fan is faulty?
If after defrosting and lubrication the sound does not disappear, and the fan rotates with visible difficulty, most likely the bearing has exhausted its service life. In this case, only replacing the unit will help.
Creak of the door and seals
Sometimes the source of irritation is not the equipment, but its door. If you hear a characteristic creaking noise when opening, the problem lies in the hinges or rubber seal. Over time, the hinges wear out, dust gets into them, and metallic friction increases.
To eliminate the creaking of the hinges, they must be lubricated. Depending on the design, access to the mechanism may be hidden by decorative overlays. Use spray lubricant with a thin tube to reach the pivot point. After treatment, open and close the door several times so that the lubricant is distributed evenly.
The rubber seal can also creak, especially if it is new or, conversely, too old and has lost its elasticity. The friction of rubber against the metal of the body creates an unpleasant sound. Rubbing the seal with a special rubber conditioner or regular silicone grease will help solve the problem.
- 🚪 Check the geometry of the door: if it is skewed, the load on one of the hinges will be higher, which will cause creaking.
- 🧼 Clean the end of the door and the body from adhering fat and dirt, which act as abrasive.
- 🧴 Regularly treat rubber with silicone to prevent drying out and cracking.
It is important to monitor the condition of the seal, since its damage leads not only to noise, but also to loss of cold, which increases energy consumption. If the rubber is cracked, it is better to replace it entirely.
Prevention and general recommendations
To prevent the creaking of the refrigerator from becoming a constant companion of your life, it is important to carry out regular prevention. Even if the equipment is currently operating silently, periodic inspection will extend its life. Once every six months, it is recommended to move the unit, wipe the rear grill from dust and check the stability of the legs.
Do not overload the shelves and do not place heavy bottles on the door if this is not provided for by the design. Load imbalance leads to deformation of the body and hinges, which is guaranteed to lead to the appearance of extraneous sounds in the future. Uniform distribution of products inside the chambers is the key to quiet operation.
Monitor the temperature conditions. Setting the temperature too low causes the compressor to run almost continuously, which increases wear and tear on all moving parts. The optimal temperature in the main chamber is +4...+5°C, and in the freezer compartment -18°C.
If you notice that the nature of the noise has changed, do not wait for a final breakdown. Timely lubrication or adjustment can save the situation. Remember that cheap repairs at an early stage are always more profitable than replacing expensive components later.
Why does a new refrigerator squeak?
A new refrigerator may squeak due to shipping bolts that have not been removed, or because the parts have not yet “got in.” It could also be due to uneven installation in the new space. Let the equipment stand for several hours after turning it on so that the refrigerant is distributed, and check the installation level.
Is it possible to lubricate the refrigerator without turning it off?
It is strictly forbidden to carry out any repair work related to removing panels or accessing electrical parts while the refrigerator is plugged in. This is life-threatening and may cause a short circuit. Always unplug the device from the outlet before starting work.
The creaking disappears if you press the panel with your hand. What to do?
This is a sure sign that the panel is poorly secured or resonates. You need to remove this panel, check the integrity of the fasteners and, possibly, seal the contact points with vibration-proof tape or sealant before reinstalling.
How often should door hinges be lubricated?
It is recommended to carry out preventive lubrication of the hinges once every 1-2 years, or as soon as squeaking occurs. If you use a spray lubricant with Teflon, it lasts longer and attracts less dust than conventional oil-based compounds.
