Why Did The Refrigerator Start Working Loudly?
The situation when the refrigerator works loudly can not only cause some discomfort to a person but also affect the performance of the product.
The refrigerator is an irreplaceable device, without which it is almost impossible to imagine modern life. Its use gives a person many benefits, allowing you to extend the shelf life of products and making it possible to preserve them for a long time. It has a rather complex technical structure and requires periodic prophylaxis. Based on this, as a result of the operation of the device, various difficulties may arise that can lead to the formation of malfunctions.

Refrigerator design and possible causes of noise generation
Not every refrigerator can operate silently. As for the models that have exhausted their technical and functional resources, rattling and rumble are their constant companions. In turn, modern devices are designed in such a way as to create as little noise as possible, and exceeding a certain sound threshold for them is a deviation from the norm. However, no matter how new and technically prepared the refrigerator is, one fine day its operation may begin to be accompanied by increased emission of noise. No one can be insured against such an outcome, but everyone can try to prevent such a development of events.
To understand the reasons for the formation of a rumble and rattling, you should turn your gaze to the design of the device, since the answer to the question of why the refrigerator works noisily lies in it. In most cases, the main source of extraneous sounds accompanying the operation of the product is the compressor. It is he who is included in the work when the temperature inside the chamber rises, contributing to its lowering.
Modern compressors are designed to generate the lowest possible noise. However, under the influence of some factors, both external and internal, their characteristics may be violated. The main reasons for this process:
- wrong location;
- freezing of ice on the walls and the tubes;
- compressor shock absorbers are loose.
All these factors can lead to the fact that one day the refrigerator will start working loudly, causing discomfort to a person and disrupting the regularity of his life.
At the same time, their untimely elimination can lead to a complete failure of the compressor, which is the most negative consequence and requires a full-fledged expensive repair or a complete replacement of the refrigerator.
How do I stop my fridge from making a loud noise?
Usually, after purchasing a new refrigerator, users do not experience problems with this technique. However, older devices may generate noise during operation. This may be due to several reasons. Let’s consider what to do in each situation.
The refrigerator is not installed correctly
The most common cause of extraneous noise is improper installation of the refrigerator, that is, the requirements for its horizontal and vertical position have not been met. This is very easy to do. It is enough to use the building level during installation and check the position of the equipment with it. If the refrigerator does not stand correctly, then the compressor will make noise during operation. It will come in contact with pipelines and other metal parts of the equipment.
To install the refrigerator on a level, twist its legs
Also, the refrigerator can make noise because during installation the user did not pay attention to the position of its legs, as a result of which one of them may simply hang in the air. This will make the refrigerator unstable during operation. Therefore, in addition to checking with a level, it is necessary to control the position of the legs. Tighten them if necessary.
Lack of air for compressor operation in refrigerator
One of the most common causes of refrigerator noise is limited capability mode. This happens if, during the installation of the equipment, it was pushed too close to the wall, furniture, or other surfaces. When the back of the refrigerator is close to something, the condenser is not getting the right amount of air. As a result, the unit does not cool properly and the compressor is loaded. As a result of this, it is overloaded, and it begins to emit extraneous sounds. They come from a valve, motor, or vibration from other components in the system.
To fix this problem, it is enough to check how close the refrigerator is located with the back panel to the wall or other surface. If necessary, it must be pushed aside so that the distance between them is at least 20 cm.
It is unacceptable to place the refrigerator next to the stove!
Loose compressor housing in refrigerator
However, sometimes situations arise when these problems have been eliminated, and extraneous noise is still present. In this case, it is recommended to check that the fastening is secure. The bolts in the seating area have likely loosened during operation.
If the user is dealing with an old model of the refrigerator, then it must be remembered that the compressor in them hangs on springs. And they can shift or weaken over time. As a result, the compressor housing may come into contact with other parts and generate noise. For example, if the engine is close to the pipes of the refrigerator, then the sound from the vibration will be very strong.
Damaged gaskets under the engine housing can be another source of the noise. In any of these situations, it is necessary to replace parts, springs, or gaskets.
On the other hand, inattention of the user may be the cause of the noise. If during the installation of the refrigerator, he forgot to dismantle the transport bolts, then the engine may make noise from behind them. These bolts are long studs that hold the compressor in place. They are necessary so that during transportation it does not damage other units of equipment.
The location of the transport bolts should be specified in the instructions for a specific model.
Fan problem in refrigerator
This problem is relevant only for modern refrigerators equipped with the “No Frost” function. They can house not one, but two fans. They are usually responsible for cooling the evaporator. One refers to the refrigerator compartment, the other refers to the freezer. If they malfunction, the refrigerator will make a very loud noise.
If temperature fluctuations occur regularly, the lubricant in the fan bearings dries up. The node begins to vibrate and make a loud noise. In addition, due to its poor performance, ice may appear on the walls of the chamber, which can also become a source of extraneous sounds. This is since the fan starts to touch it during operation.
To eliminate this problem, it is necessary to remove the ice from the evaporator. It’s easy to do it yourself. After that, it is necessary to inspect the bearing and, if necessary, lubricate it. Since most models have a brass or bronze bearing, it is essential to lubricate it.
Faulty electrical circuits in refrigerator
The start-up relay of any technique in the event of a malfunction begins to behave strangely. This also applies to refrigerators. The broken relay starts to buzz, make growling sounds, and after a while turns off. It is almost impossible to fix this problem with your own hands. We’ll have to replace the relay, and for this, turn to the services of specialized service centers.
In addition, a burnt winding of the fan motor can be the cause of the noise. If there are such suspicions, they must be checked with a tester. If a short circuit or resistance leak is detected on the compressor housing, the motor must be replaced.
A burnt-out compressor motor can also cause the refrigerator to operate noisily. It is quite simple to check this – just touch the motor housing with your hand. If it is too hot, then the engine will have to be checked and most likely replaced.
Another reason for the appearance of noise can be a burned-out heating element of the evaporator. This will create ice build-up on the evaporator, which will negatively affect the operation of the compressor. In this case, you will have to check the heating element with a tester and, if an open circuit is found, replace it.
Symptoms of a malfunctioning refrigerator
Any small detail can tell you that something is wrong with your refrigerator. To find out exactly what could have broken down in your refrigeration appliance, you need to know exactly the signs of a malfunction of its main components:
- when the refrigerator door is opened, the lighting lamp does not light up;
- during operation of refrigeration equipment there are extraneous noises and rattling;
- you notice water leaking near the appliance;
- frost and ice are rapidly freezing in the freezer;
- insufficient generation of cold;
- no cooling when the compressor is running;
- after a short time after switching on the refrigerator switches itself off.
The refrigerator does not turn on
If, when the refrigerator is turned on, the light does not light up, but the unit itself continues to work, then most likely you just need to replace it. Another thing is that the light does not light up and your equipment does not start functioning. The first thing to do is check if there are any connection problems. For this:
- check the outlet;
- check the cord;
- check the plug.
The thermostat may be damaged or incorrectly configured. Set the handle to the desired position and check if it is held at the specified level.
If during such a test inspection the trouble is eliminated, then consider yourself lucky. If the problem persists, then, most likely, the thermostat is out of order. He is responsible for controlling the temperature in the cells. This unit is also called a thermostat.
Important! The thermostat is fixed in the same block as the light bulb. It consists of the sensor itself and two wires connected with a terminal. To fix the problem, try to free these wires and short them together. If, after such manipulations, the compressor starts working, then the thermostat will have to be changed.
The refrigerator starts, but after a few seconds it turns off
Listen to the work of your cold generator. If, after a few seconds after switching on, a characteristic click is heard, and then the device turns off, then the root of evil is a compressor breakdown. This is the “heart” of the refrigerator. Sometimes it turns out to be cheaper to buy new equipment than to replace a motor compressor.
The compressor is found in many types of household appliances. Its breakdown makes the device unusable, and repairing it costs almost like a new technique.
If, before disconnecting, you did not hear a characteristic click, then the cause of the breakdown is the start-up relay. Replacing it will not be a big problem, it is located on the back of the refrigerator in the lower section. It connects to the refrigerator with two wires fastened with a terminal. For a home craftsman, replacing such a relay will not be difficult.
The relay may simply go off or be incorrectly latched. You need to disconnect the refrigerator from the mains and check the part. If, after correcting the situation, the situation remains the same, then you need to change the relay.
If the usual work intervals are violated, you should pay attention to the electronic board. Often, in the event of a breakdown, it gives the wrong signals – the refrigerator turns on, but after working for only a few seconds, it turns off. If you are not strong in replacing electronic components, then it is better to contact a specialist. Elimination of such a malfunction does not take much time, and the cost of repair is low.
The refrigerator works but does not freeze
If the device works but does not produce enough cold, then the most common cause of failure is freon leakage. This can happen due to the cracking of the metal welds. Unfortunately, over time, a similar malfunction occurs in almost every unit.
It is impossible to independently determine the leakage of freon since it has no color or smell. Therefore, you cannot do without a specialist.
In such a case, you will have to call a refrigeration repair technician. He diagnoses a malfunction of the refrigerator and determines the freon pressure in the system. The control of this most important indicator is carried out using a special technical pipe. Since freon is fire hazardous and admission is required for its injection, you should not try to fix such a breakdown on your own.
This problem can be solved by refueling freon, which happens quite quickly.
But there are other, less serious reasons why a refrigerator can break. To provide for all the nuances, you must perform the following steps.
- Back to the temperature control sensor again. Just try to change its position.
- Check if the seals on the unit doors are worn out. It is easy to replace them, only beforehand it is worth completely defrosting and washing the household appliance.
- Try bringing your hand to the compressor. If it is overheated, then, most likely, the protection has worked. To remedy the situation, unplug the refrigerator and plug it back in after 30-60 minutes. The motor just needs time to cool down.
If despite all efforts, it was not possible to establish the problem due to which the device could break down, then you will have to call a qualified repairman.
The refrigerator freezes slightly
To understand what can break in the refrigerator if it starts to freeze weakly, you do not need to resort to complicated conclusions.
Even if the refrigerator began to cool not as much as before, you still need to pay attention to this.
The main reasons for this breakdown are in many ways similar to the complete absence of cold and may be as follows:
- the rubber seal of the refrigerator door is damaged or worn out;
- the sealing of the refrigerator is broken due to skewing or deformation of its door;
- the thermostat is out of order;
- there is a leak of refrigerant, that is, all the same freon;
- the main element has broken down – the motor-compressor. Unfortunately, this reason often leads to the fact that the device has to be scrapped, and it is easier to purchase a new refrigerator.
The most easily eliminated causes can be identified independently by visual inspection.
The refrigerator is very cold
The formation of “snow” on the walls of the refrigerator is another clear sign of equipment malfunction.
The opposite situation – excessive production of cold during work, can be associated with the following factors.
The refrigerator is very freezing and there is an accumulation of water in the lower sections. Most likely, the drainage hole is clogged, which you can clean yourself.
The same thermostat is out of order. To check – try to twist the sensor regulator. If there is no reaction, replace the thermostat.
Another common cause is a blockage in the capillary system of the device. As a result, the compressor cannot pump refrigerant through the system. It is necessary to clean, refill the refrigerator with freon and check the oil (it may need to be replaced). In this case, you will have to call a refrigeration repair technician.
Housewives should know that defrosting the refrigerator is necessary for preventive purposes. If you have a model from the “No Frost” series, then you can do this no more than once a year.
The first thing to do in this situation is to completely defrost the refrigerator, clean the drain and check the thermostat. If the total is zero, call a specialist.
If water accumulates under the lower drawers in the refrigerator itself, the drainage hole is clogged, which will have to be cleaned. You can do this yourself. This will require a medical rubber bulb.
- take hot water into a medical bulb;
- insert its tip into the drain hole and press sharply;
- Pump out all the water with a pear. You will have to press and pump out several times, but this will eliminate all blockages in the drainage system;
- perform the procedure after switching off and complete defrosting.
The second reason is that the hole through which the water leaves is clogged. It can also be cleaned with a syringe or fishing line.
If even after such manipulation water continues to accumulate, then it is better to call a repairman.
Lighting malfunctions in refrigerator
If the light does not turn on when you open the refrigerator door, just look to see if it is “burnt out”. Replacing an incandescent lamp takes a few minutes and does not require special skills. It’s another matter if, even after that, problems with electricity persist. This indicates a malfunction of the electromechanical circuit. If you have no experience with the elimination of such breakdowns, then contact the master.
Do not ignore the burnout of the light bulb in the refrigerator, as this can be a sign of a malfunction of the entire system.
Malfunctioning thermostat, compressor, or other parts
A malfunction in the operation of the thermostat leads to a violation of the temperature regime in the chambers. It is quite easy to check this. Try to free these wires and short them together. If, after such manipulations, the compressor starts working, then the thermostat will have to be changed. You can do this yourself.
You should not get carried away with self-repairing the refrigerator, as this can lead to more serious problems.
The compressor is more complicated. This will require the help of a specialist. To diagnose breakdowns in other nodes, you can use the special table below.
Important! If the device turns off on its own and this is preceded by a click, then the problem is localized precisely in the compressor.
Clogged drainage system in refrigerator
Make sure the fridge odor is not associated with rotten food.
A clogged drainage system will cause an unpleasant odor and water leakage in the lower sections of the appliance. You can fix this problem with a regular rubber bulb. The process of cleaning the drainage system is quite simple. Pour hot water into the pear, insert the tip into the drain and pump it under pressure and then suck it out.
Loose closing of doors or breakage of sealing gum in refrigerator
If the refrigerator doors are not closed tightly, thermoregulation is disturbed and the device may produce insufficient, or vice versa, an excessive amount of cold. Note that ice may be interfering with hermetic closure. Then just turn off the appliance until it is completely defrosting and wash the chambers thoroughly.
Sometimes the accumulated debris can interfere with the tight closure, so you need to periodically clean this part.
If upon visual inspection, a violation of the integrity of the elastic bands is visible, then they will have to be replaced. Similar components are sold in specialized stores. Before buying, check the model of your refrigerator and measure the length of the rubber bands.
Malfunctions of the “No frost” system
The most common failure is defrosting cycle failure. The result is a kind of “overgrowth” of the evaporator with frost. Because of this, the refrigerator starts to freeze badly, and the temperature in the chambers rises.
Important! Do not use the forced freeze function for more than an hour. This will cause frost to build upon the evaporator.
You can independently check the operation of the forced defrost timer. If the compressor does not turn off when you turn the knob, then the reason is precisely in the timer. We’ll have to replace him. If the timer runs out, try defrosting the refrigerator completely. After that, the problem does not self-destruct – call the wizard.
Why Did The Refrigerator Start Working Loudly?
If you notice at least one of the listed malfunctions behind your household appliance, you should fix it on time. Otherwise, expensive repairs will not be enough.
