Why does the refrigerator crackle at night?


Features of the refrigerator

In any kitchen, the refrigerator occupies an important place. The equipment is irreplaceable and works for years, so its breakdowns become a serious problem. Considering this fact, it is advisable to choose a reliable manufacturer - Bosch, Hotpoint-Ariston. These companies, in addition to product quality, offer developed and qualified service. However, no brand gives a 100% guarantee, so breakdowns are inevitable, especially after 4-5 years of operation. It is important to properly monitor your kitchen appliances to understand why your refrigerator is cracking.

The operating principle is based on the transfer of heat from the inner chamber to the outside. A special liquid is distilled in a closed loop to maintain the desired temperature. The peculiarity of the equipment is that it is designed to work without interruption for literally years, so the load is extremely high.

Main elements of the system:

  • Compressor – is responsible for distilling freon through the circuit and directly provides cooling.
  • Condenser - quickly removes heat and promotes cooling.
  • Evaporator – converts freon into a gaseous state.

All nodes interact with each other. If something goes wrong, the refrigerator knocks, why this happens is a question that experienced service specialists will answer.

Primary diagnostics of the refrigerator

Household appliances differ in design features, but certain problems occur on all types - drip, No-Frost, etc. Budget models Atlant, Biryusa, Indesit, Liebherr are very popular. First you need to check the severity of the problem:

  • The refrigerator clicks but does not turn on.
  • Extraneous sounds appear periodically at different stages.

Thus, two situations are considered: clicking is the only suspicious symptom or the device completely stops working.

Clicks in the new refrigerator model

After the purchase, people wonder why the new refrigerator clicks. It is necessary to observe the operation of the device and consult with specialists. If the temperature in the refrigerator and freezer is correct and there are no deviations, then clicks are one of the operating features. The device may click when turned on or off, or crackle slightly. If this situation does not cause discomfort, then there is nothing to worry about.

The refrigerator makes a cracking sound

Even the appearance of extraneous sounds does not always indicate that the equipment has become faulty. If the cooling works without problems, the following circumstances may be the cause:

  1. The material of the internal walls, which was deformed due to temperature changes.
  2. The operation of the thermostat when the engine starts. This is especially true for newly purchased equipment.

Why does the refrigerator shoot?

In a normal situation this could be:

  1. The compressor switches power depending on the indoor and outdoor temperatures.
  2. As temperature changes, the elements of the cooling circuit contract and expand.
  3. Small vibrations affect metal and plastic parts, causing them to move.

The operating features of the compressor, thermostat and the mobility of individual elements are the most likely reason why the refrigerator cracks in normal condition. It is also worth checking how well the internal shelves and stands are secured. This is typical primarily for budget models.

Remember: if a household refrigerator copes with its tasks, maintains the desired temperature and a low overall noise level, then individual clicks should not cause serious concern.

How to solve a problem?

Depending on the level of complexity of the problem, you can solve it yourself in the following ways:

  1. Change the angle of the refrigerator.
  2. Adjust the compressor support springs.

This is the simplest solution to the problem, and you can cope with such work without additional help, but it is still recommended that in case of problems with household appliances, contact a specialist who will find out why the Hotpoint Ariston refrigerator is cracking, competently replace damaged elements or restore their functionality . By the way, the prices for the services described above in the refrigerator repair service fall into the category of the cheapest work.

Why did extraneous sounds appear?

Loud noises that appear suddenly after a long period of work cause concern. This is a reason to call a specialist to your home. To do this, you need to call the manufacturer’s hotline - Samsung, Ariston, Bosch or any other. Defects in large household appliances are dealt with by the brand through its own service centers, and not by the retailer. If a home technician determines what might be clicking in the refrigerator and determines that there is a defect or a manufacturing defect, you can contact the store for an exchange.

Common symptoms:

  • The motor does not turn on, and clicks are heard periodically from behind the unit.
  • The light is on, but the engine does not start, it only hums and clicks.
  • Before starting, clicks are heard in the relay.

The situation is repeated with varying degrees of consistency, and therefore causes concern. In this case, qualified diagnostics will not hurt, but if you wish, you can figure out on your own why the refrigerator is knocking when it is turned off or started.

Let's look at common reasons:

  • If the unit only clicks, does not freeze, and the light does not come on, the start-protection relay is broken.
  • It clicks, does not start, but the light is on - the thermostat is broken (no command is received when the temperature becomes higher than normal).
  • It hums, does not start and after a while turns off with a strong bang - a problem with the compressor, which is trying to start, but overheats.

If the refrigerator rattles or crunches over time, but still works normally, then perhaps the reason is only loose fasteners. Constant vibrations have a negative effect on the body elements, so it is enough to check them and tighten the bolts. This is the same reason why the refrigerator creaks during operation.

At some points the device starts ticking due to a problem with the network - the relay tries to start, but nothing happens. The clicking sound is an attempt to launch. This problem is faced by summer residents or owners of private houses in remote areas. The equipment itself is in perfect order; it is enough to install a voltage stabilizer and a surge protector for safety.

When a cracking sound indicates a breakdown

A household refrigerator creaks and clicks when the motor is running. There is often a rattling noise, which is not a problem. Sometimes noise signals a malfunction of the device. To understand the situation, it is necessary to study the possible causes of noise.

A cracking noise when starting a compressor often indicates a breakdown:

  1. The engine tries to start several times, hums and runs for a couple of seconds, then stops - most often it needs to be replaced.
  2. When the unit starts, the start relay clicks, but the light inside the chamber does not light up, and the refrigerator does not start - the reason lies in the relay failure.
  3. If there is a rattling sound when the engine is turned off, the motor mountings must be checked; most often they will need to be tightened so that the compressor does not vibrate. In this situation, you can try to adjust the inclination and height of the legs of the household appliance.
  4. Clicks are heard periodically, there is light in the chamber, but the unit does not cool - this indicates a malfunction of the thermostat: the engine tries to turn on, but no signals are received from the thermostat, which needs to be replaced.
  5. Clicks that are heard several times in a row with pauses between them indicate an insufficient voltage level in the network or breakdowns in electrical parts and wiring - the plug, contacts and network must be checked. It is worth purchasing a current stabilizer if the situation does not improve.

A clicking sound that sounds more like a loud murmur indicates that the cooling system needs to be checked. The pipes could be clogged, or there might be a freon leak.

Troubleshooting

Some breakdowns do not cause serious concern because they can be fixed independently or relatively inexpensively. If the refrigerator freezes, the light inside is on, but only occasionally crunches, then most likely this is just a characteristic feature of a particular model. Especially if such sounds appeared from the very beginning.

In other situations, the problem occurs with the thermostat (the light is on, but the device does not respond), with the relay (humming, ticking), with the compressor (does not freeze). For service, it is worth calling a technician to your home so that he can carry out an accurate diagnosis. You should only carry out minor repairs yourself - check the fastenings of the wall, motor, relay.

If the household appliance is still under warranty, you need to call the manufacturer’s hotline - Samsung, Biryusa or any other. The store where the purchase was made will tell you what to do in such a situation. An at-home specialist will inspect, repair the device or write a technical condition report. On the basis of this paper, the defective product is exchanged in the store. It is advisable to save the cash receipt and other documents so that you do not have to restore them.

After the warranty expires, you should simply call a technician to your home from an authorized service center. There is no need to transport large equipment anywhere on your own. Typically, for popular models, repairs even with replacement of parts will cost from 1,500 to 6,000 rubles. It's much cheaper than buying a new refrigerator.

Types of noise and reasons for their occurrence

Refrigerator buzzing

The strong hum of the device causes discomfort: humming sounds cause irritation and interfere with a comfortable life. The problem is known for old refrigerators that have been in operation for more than 10 years and new models: Hotpoint Ariston, etc. If the refrigerator makes a loud noise, look for the cause among the following points:

  • Adaptation after purchase. The device requires time to debug normal operation. In the first week, the equipment is louder than expected.
  • Incorrect setting. If you set the thermostat value to maximum, the motor will operate under heavy load conditions, producing an unpleasant hum.
  • Breakdown of the compressor, piston system.
  • The refrigerator comes into contact with furniture and walls, transmitting motor vibrations to them.
  • The network voltage drops; Due to power outages, the mechanisms wear out and begin to work incorrectly.

If the problem cannot be corrected, contact the service technicians.

Refrigerator rattling

Knocks, ringing and crackling can be caused by:

  • Failure of the electric motor;
  • Incorrect location (equipment installed at an angle on a curved surface);
  • The transport fastenings of the compressor have not been removed;
  • Objects vibrate inside the chamber;
  • Evaporator tubes and compressor protective casing rattle;
  • The electric motor elements are worn out.

Refrigerator creaking

The following can cause creaking inside the device:

  • Fan installed in the freezer compartment. Over time, ice accumulates on the blades, which interferes with the rotation of the impeller;
  • Plastic cladding elements. The walls of the chambers narrow and expand under the influence of temperature changes, producing a grinding sound;
  • The refrigerator is installed on an uneven floor: elements and mechanisms come into contact with each other and crack;
  • The compressor is worn out: in the near future the device will stop working properly.

Whistle when the refrigerator is running

Hissing and whistling appear for the following reasons:

  • Movement of refrigerant through the pipes of the cooling system: this is a normal circulation process;
  • Wear and clogging of evaporator tubes;
  • Compressor malfunctions;
  • Fan blades are dirty.

The appearance of extraneous sounds in the Ariston refrigerator, which previously worked quietly, is an alarming signal. The malfunction must be found and eliminated in time to avoid costly repairs and replacement of mechanisms.

Call +7 905-816-82-69 to order diagnostics and call a specialist to your home. The employee will arrive at the address in Orenburg and the region at the agreed time; will conduct an inspection; determine the cause of the breakdown; will set a price and carry out repairs.
