Owners of household appliances are often faced with a situation where the usual smooth hum of the unit is replaced by annoying rattling or loud knocking. If The Indesit refrigerator is rattling, this symptom cannot be ignored, as it may indicate wear of the moving parts or incorrect installation. Modern models, such as Indesit EF 18 or DSB 200, are designed for quiet operation, so the appearance of extraneous sounds is a signal of the need for diagnostics.
The first thing to do is to determine the nature of the sound. This may be an intermittent clicking sound, a continuous rumble or vibration of the housing. Refrigerator noise often occurs due to the fact that the motor-compressor is working under increased load or is losing balance. In some cases, the problem lies not in a breakdown, but in a banal violation of operating rules.
Self-diagnosis allows you to save your budget, since many faults are eliminated without calling a technician. However, if compressor makes metallic clanging sounds, this may indicate serious internal damage. It is important to distinguish between operating noise and emergency knocking in order to prevent complete failure of the equipment.
The main causes of noise when the motor is running
The main source of sound in any refrigerator is the compressor. The models Indesit use both classic piston and more modern inverter engines. If the unit rattles, it means that the operation of its internal mechanisms or fastenings is disrupted. Often the cause is wear of the piston group or valves.
When motor-compressor gets old, the gap between the parts increases, which leads to shocks and rattling. It is also worth checking whether the motor housing itself is vibrating against the metal elements of the cabinet. Sometimes it is enough to place a rubber gasket to eliminate resonance.
Another reason may be overheating. If condenser clogged with dust, the compressor works harder, trying to maintain the set temperature. This leads to increased vibration and the appearance of characteristic rattling. Regular cleaning of the heat exchanger helps prolong the life of the unit.
⚠️ Attention: If you hear a loud metallic knock immediately after turning on, immediately unplug the device. Continuing operation may lead to jamming of the motor shaft.
The influence of incorrect installation on the noise level
Often the answer to the question why the refrigerator hums and rumbles lies in its location. If the equipment is installed unevenly, a misalignment occurs, which is transmitted to compressor. In models Indesit with a lower engine location this is especially noticeable. The housing begins to resonate, amplifying any operating sound.
Check the distance to walls and furniture. If refrigerator stands close to the wall, vibration is transmitted to building structures, creating an echo effect. The gap should be at least 5-7 cm for free air circulation and vibration damping.
Pay special attention to the legs. They must be unscrewed so that the door closes itself when opened to 45 degrees. If supports are not adjusted, the housing will wobble and the inner tubes may touch, creating a clanging sound. Use a building level to make precise adjustments.
- 🔹 Make sure the floor under the refrigerator is level and can support the weight of the equipment.
- 🔹 Check that the back elements of the cabinet are not touching the wall or heating pipes.
- 🔹 Make sure that the shipping bolts have been completely removed (if applicable to the model).
- 🔹 Try moving the unit slightly - sometimes this changes the resonant frequency.
Rattling of tubes and elements inside the chamber
Inside the refrigerator there is an capillary tubes and evaporator. Over time, vibration may cause their fastenings to become loose. As the refrigerant moves through the system, the tubes begin to vibrate and hit each other or the walls of the chamber. This creates a characteristic ringing rumble.
To fix the problem, you need to carefully remove the back panel (in some models Indesit it is plastic) and inspect the condition of the pipelines. If you find loose areas, they need to be fixed. To do this, you can use special clamps or soft insulating material.
It is important not to pinch the tubes, as this will disrupt the circulation. Freon. Light tapping can also be produced by ice if the system No Frost is not working correctly. In this case, defrosting or checking the defrost heating element is required.
Problems with the fan in the No Frost system
B refrigerators Indesit with a system No Frost a fan is responsible for air circulation. If it rattles, most likely ice has frozen on its blades or a foreign object has fallen into it. Also, the cause may be wear in the bearings of the fan itself.
When ice freezes, the fan begins to touch the ice crust, producing a loud cracking or hum. This often happens if the door seal does not fit tightly and moist air enters the chamber. In this case, it is necessary to completely defrost the refrigerator within 24 hours.
If the noise remains after defrosting, it means it has failed. fan motor. Replacing it does not require complex tools, but requires care when connecting the wires. Also check to see if the fan power wire is kinked, which could cause a humming noise.
⚠️ Attention: Do not try to forcibly turn the fan blades if they are frozen. This can break the plastic propeller or burn the motor winding.
Diagnostics of faults by sound type
Experienced technicians can determine the cause of the breakdown simply by listening. Indesit refrigerator. Different types of sounds indicate different nodes. For example, an intermittent knock often indicates problems with the start relay, and a continuous hum indicates a load on the compressor.
If you hear gurgling and overflowing, this is usually normal operation of the refrigerant. But if rattling is added to this, it is possible that a plug has formed in the system or the oil circulation has been disrupted. The table below shows the main types of sounds and their probable causes.
| Sound type | Probable cause | Difficulty of repair |
|---|---|---|
| Metal clanging | Wear of the piston group compressor | High (compressor replacement) |
| Crackling noise when turned off | Thermal expansion of materials or relays | Low (normal or relay replacement) |
| Humming with vibration | Improper installation or touching of the tubes | Low (adjustment) |
| Whistling or howling | Fan malfunction or blockage | Average (cleaning or replacing) |
| Clicks when starting | Malfunction of the starting relay | Average (replacing the relay) |
By analyzing the data in the table, you can understand whether it is worth taking on repair yourself. Replacement start relay is available to most users, while replacing a compressor requires special tools and skills in working with freon.
When you need to call a technician and professional repairs
There are situations where independent intervention can only do harm. If compressor it buzzes, but does not start, and after a while there is a click and again silence - this is a sign of a breakdown of the trigger mechanism or a break in the winding. Here you need a specialist.
Also, the help of a professional is necessary if a leak is suspected. refrigerant. If the refrigerator rattles, but does not cool, and an oil coating is visible on the tubes, it means that the freon has leaked. Charging the system requires evacuation and precise dosage of gas.
A master will also be required if the electronic control module has failed. In modern models Indesit with electronics controller can send incorrect signals to the engine, causing it to operate in emergency mode with increased noise.
How much does it cost to repair a compressor?
Replacing a compressor is one of the most expensive procedures. It includes the cost of a new unit, soldering of pipes, evacuation of the system and refilling with freon. It is often more economically feasible to buy a new refrigerator if the old one has served for more than 10 years.
☑️ Diagnostics before calling a technician
Noise prevention and extending service life
To Indesit refrigerator work quietly for many years, it is important to follow the rules of prevention. Regularly wipe off dust from the condenser at the back of the unit. This will improve heat transfer and reduce the load on the motor, reducing the noise level.
Monitor the condition of the sealing rubber bands. If they become dry or dirty, the door will not close tightly. This will cause the compressor to turn on frequently and ice to freeze on the fan, causing rattling noise.
Do not load the shelves with excessively heavy products, especially glass jars. Vibration from the operation of the compressor can cause them to rattle, creating the illusion of equipment failure. Use special mats or pads for heavy containers.
⚠️ Attention: The characteristics of the equipment and design may vary depending on the specific series and year of manufacture. Always check the official instructions for your model Indesit before disassembling.
To summarize, we can say that if The refrigerator is rattling, no need to panic. In most cases, the problem is solved by adjusting the legs, defrosting, or replacing inexpensive parts like a fan. However, if the sounds are accompanied by loss of cold, it is better not to risk it and contact a specialist.
Is it normal if the refrigerator makes gurgling sounds?
Yes, this is normal. The sounds of liquid (freon) flowing through the tubes are a natural process of the operation of the refrigeration circuit. If the gurgling is not accompanied by strong pump noise or vibration, there is nothing to worry about.
Is it possible to lubricate a compressor if it rattles?
No, modern compressors in refrigerators Indesit are sealed and maintenance-free. An attempt to drill a hole for lubrication will lead to an instant leak of freon and damage to the unit. The grease is poured inside at the factory.
Why does a new refrigerator hum loudly?
New equipment may hum louder due to the grinding in of parts. Also check that all shipping locks have been removed and that the clearance to the wall is correct. If the hum does not subside after 3-5 days, this may be a factory defect.
How to distinguish the noise of a compressor from the noise of a fan?
The noise of a compressor is usually low-frequency, muffled and comes from below from behind. The fan noise is higher-pitched, similar to humming or crackling, and comes from the top of the freezer or the back wall inside.
