Freezers - A specialized type of refrigeration equipment designed for long-term storage of products. Inside the compartments of such a chamber, low temperatures are constantly maintained. This allows you to save meat, vegetables and fruits, vegetable mixtures and other products for several months. IN recent years freezing cabinets began to be used not only in commercial activities, but also in everyday life. Many people like to enjoy fresh strawberries, raspberries and other fruits. In addition, unlike preservation and heat treatment, the products retain all useful substances and vitamins when frozen.
Freezer
But so that your winter blanks do not deteriorate, it is important to ensure the continuous operation of the equipment. Compliance with the rules of operation and recommendations for care is the key to long-term operation of the equipment. And if something went wrong, and your freezer stopped working - you need to act very quickly. The account does not go for days, but for hours!
Normally, the set temperature should be constantly maintained in the freezer; ice does not freeze on the walls. Listen to your device periodically. The compressor makes a characteristic noise during operation, but if extraneous sounds appear, this may indicate a problem. Do not ignore it.
The freezer is noisy: malfunction or normal?
Note that currently there is a tendency to reduce the noise level in household devices. Manufacturers come up with new technological solutions. Meanwhile, to date, completely silent models do not exist. Noise level is indicated in decibels in the instruction manual.
If the equipment is noisy, but no additional signs are observed: water does not leak, there is no burning smell, the display shows the operating temperature, there are no alarms and error codes, most likely, you should not worry!
All sounds are natural. So, crackling emit elements of the cooling circuit.
Refrigeration and freezer motor compressors
When the motor-compressor is turned on, the freezer starts up, the thermostat clicks. A similar thing happens when you turn off: click - and the motor stops buzzing.
When is noise the norm?
But if your freezer clicks, tries to start up and immediately turns off or the engine hums - there are problems with the compressor. This can be an interturn winding or a short circuit. A motor replacement is required. This is an expensive repair.
It happens that the motor knocks very hard when turned off. This suggests that the compressor mounts have loosened. As a result of this, during operation, the engine dangles so that it touches the body, and then turns off. At this time, a knock is heard. To eliminate this malfunction, the motor position must be adjusted. The main thing is not to delay the repair. Otherwise, the compressor may burn out.
If the thermostat breaks, clicks are heard, but the engine does not start. Due to the fact that the compressor is constantly turned off, the freezer does not freeze, respectively, the temperature in the drawers rises. If you have problems with the thermostat, you will hear only loud clicks, and no more extraneous sounds. However, if the technician constantly clicks, the problem may not be with the thermostat, but with start-up relay.
Fridge start relay
The next “culprit” of noise is quite insidious and can do a lot of harm. We are talking about power surges and low mains voltage. If the current is very weak, the motor will not start. Accordingly, you will hear the clicks of the start-up relay, but nothing will happen further.
It’s easy to get rid of this problem, just install a high-quality voltage regulator.
To ensure that the equipment runs smoothly and does not break - use a voltage stabilizer
Why is the freezer buzzing?
If your freezer suddenly buzzed, the reason may be due to the following factors:
- The unit is too close to the wall or to the wall of the kitchen furniture. Because of this, the motor starts to vibrate, as a result of which the elements that are nearby are humming.
- Constant power surges in the household network (in addition to clicks, there may be a buzz).
- Compressor malfunction. Typically, winding closure.
- The temperature controller of the camera is set to the maximum value. For this reason, the compressor runs to the limit of its capabilities, undergoes overloads and, due to this, emits a hum.
- You have just purchased the equipment, and it goes into operation. As a rule, this period lasts 5-7 days.
Knocking and vibration in the freezer
If the freezer knocks, shakes and trembles, you do not need to panic right away. But you still need to pay attention to this problem. Shaking may be due to the following factors:
- Knocking metal when turning on / off the motor. As previously mentioned, the reason may be due to the fact that the mounts were loosened.
- Incorrect installation of freezing equipment. Technique is not up to standard. It is especially important to pay attention to the correct installation in the event that your floor is too uneven with strong differences in height.
- After buying a freezer, you forgot to free the equipment from the transport bolts. Check this point, and if the transport screws are still standing, remove them urgently.
- Deterioration or weakening of shock absorbers of the motor compressor. Because of this, strong vibration from a running engine occurs.
Crackle and creak of the freezer
If you listened to the operation of your equipment and heard that the cabinet creaks or makes clattering sounds, the reason may be as follows:
- You haven’t defrosted the cabinet for too long, because of this a lot of ice has formed on the walls of the chamber. This ice is touched by the fan blades of the Nou Frost system, as a result of which a characteristic crack is heard.
- Due to improper installation of the freezer, some internal components and parts of the device rub against each other, due to which a rattle is heard.
- The compressor creaks. This suggests that this unit is very worn out and will soon need to be replaced. Get ready for an expensive repair!
- The creak is emitted by the walls of the case (especially if the case is made of plastic). This is due to the fact that the walls of the case, with temperature fluctuations in the room, expand and then narrow.
Install the refrigerator correctly
Whistling and hissing sounds in the freezer
Sometimes, in addition to banal clicks, knocks, owners of freezers notice that their equipment begins to hiss. With what it can be connected?
- There is dirt between the fan blades of the Nou Frost system. To get rid of such an unusual noise, just wash the freezer.
- Sounds reminiscent of gurgling and hissing can be associated with the movement of freon. This is normal and there is nothing wrong with that. But if suddenly your the freezer stopped freezingPerhaps the reason is related to a refrigerant leak.
- Sometimes the engine whistles, notifying the owners that it will soon fail.
Follow operating instructions to extend equipment life.
There are special requirements for the care of freezers, which is associated with the need to maintain a stable low temperature.
Remember to periodically defrost freezers.If the equipment is not equipped with a Nou Frost system, this must be done at least once every six months.
Do not forget to defrost the freezer
Do not leave the doors open for long. Open them as little as possible and ensure a high tight fit. Many manufacturers of modern models of refrigerators have provided additional protection - the freezer beeps with the door open, respectively, even the most absent-minded and forgetful owners will not make such critical mistakes for the technology.
Do not overload the freezer. This applies to all equipment, both domestic and commercial. In order for the motor to cope with maintaining the temperature set by the user, evenly distribute the products, at least a little free space should remain inside.
Do not overload the freezer.
As you can see, there are a lot of reasons why the freezer makes strange sounds, and they are associated with a variety of reasons. To extend the life of the equipment, do not neglect the basic rules, take care of your freezer.
