Is it normal for a fridge to hum continuously for a long time?

According to what you described, the constant humming of the refrigerator means that the compressor has been running without downtime. There are two reasons for this:

1. Thermostat.

Damaged, does not work, cannot control the compressor shutdown.

2. Refrigerant.

Leakage, causing the thermostat to not work and the compressor to run non-stop.

Solution: 1. Replace the thermostat.

2. Check the leakage point and refill the refrigerant.

You can first compare the following situations to find the reason: 1. The refrigerator is not placed in an uneven position. Uneven or unstable placement of the refrigerator is a common cause of noise in the refrigerator. The solution is to twist the adjusting screws at the bottom of the refrigerator to adjust the height and level, when the adjusting screws touch the ground and the four feet touch the ground, it is the best state.

2. There are items on the top of the refrigerator. The refrigerator and the items placed on top of it will resonate when the motor starts, causing noise. Removing the items on the top of the refrigerator will prevent it from resonating and the noise will naturally be eliminated.

3. A small object fell into the machine part at the back of the refrigerator. The rear part of the machine (in the lower part of the back of the refrigerator) that falls into small objects such as bottle caps, lighters, gadgets, etc., can also create noise. Workaround:

When you turn off the power to the refrigerator and remove small items that have fallen into the machine, the noise will disappear.

You should first check whether the refrigeration system is normal, and if the temperature in the refrigerator is low, consider whether the thermostat is set to work continuously.

It's not normal for the fridge to be buzzing all the timeAlthough the refrigerator compressor will make a sound when it is running, the sound will not exceed 45 decibels, and it will sound again at intervals. On the other hand, the buzzing is constant and loud, which may be caused by an uneven refrigerator, a damaged thermostat, or parts that are not properly secured.

1. The refrigerator is uneven

If the refrigerator is not flattened, the compressor will start to vibrate with the refrigerator while it is working, making a humming sound. This is all caused by the fridge feet tapping on the ground, and if your fridge is buzzing all the time, check to see if the fridge is not flat. If you don't put it flat, you can adjust the height of some refrigerator feet, and the height of the four feet of the refrigerator can be adjusted, even if the ground is uneven, don't be afraid.

2. The items on the top of the refrigerator resonate

In order to save space, many people even use the space on the top of the refrigerator and put small things. But if we put too many things on the top of the refrigerator, the compressor will cause resonance when the compressor is working, and when these items keep hitting the top of the refrigerator, it will also make a buzzing sound. So on top of the refrigerator, it's better not to put anything.

One will affect the heat dissipation, and it will also cause resonance of items. Reduce the service life of the refrigerator compressor.

3. Pipeline resonance

Pipeline resonance refers to the fact that when the refrigerator is working, the internal pipes are loose, and once the compressor starts to work, the exhaust pipe will vibrate, which is the humming sound we usually hear. This situation is generally caused by the loosening of the pipes caused by the carelessness of the porters during the transportation of the refrigerator, especially the loose pipes next to the compressor. It's not a big problem, just find a professional maintenance person, disassemble the refrigerator, and stabilize the exhaust pipe.

Precautions for refrigerator maintenance.

1. It is forbidden to use laundry detergent to brush the refrigerator.

In order to prevent damage to the coating on the outside of the box and the plastic parts inside the box, do not clean the refrigerator with laundry detergent, detergent, alkaline detergent, Tianna water, boiling water, oil, brushes, etc.

2. Clean the fouling in the box.

When the accessories in the box are dirty and dirty, they should be removed and cleaned with water or detergent, and the surface of the electrical parts should be wiped with a dry cloth.

3. Clean regularly.

The refrigerator should be cleaned regularly (at least 2 times a year). When cleaning the refrigerator, first cut off the power, use a soft cloth dipped in water or dish soap, scrub gently, and then dip it in water to wipe off the dish soap.

The buzzing of the refrigerator is caused by a variety of reasons, although it is annoying, most of them do not affect the normal refrigeration of the refrigerator, and it is a trivial matter that can be ignored; If you have hands-on ability, you can self-test and eliminate it:

1。The refrigerator is not placed steadily, and the noise caused by unreasonable stress --- try to shift, adjust, and add pads to make the sound smaller. (The accidental position is called the "sound bar", try transposing).

2。Loose shelves in the refrigerator, unstable placement of bottles and cans, and resonance caused by vibration--- hand press and sound will be reduced and improved.

3。The baffle and water box in the rear compartment of the refrigerator will resonate with the vibration of the compressor--- and test it by hand and adjust it appropriately to reduce the sound.

4. The resonance caused by the vibration of the compressor operation --- the resonance caused by the aging of the rubber pad at the foot and the unreasonable stress in and out of the copper pipe (after pressing the compressor or copper pipe by hand, the noise is significantly reduced, replace the rubber foot pad or adjust the stress of the pipe, including adding a rubber shock absorbing block to the pipe).

5. The wear and tear in the compressor causes the operation sound to be loud--- adjustment is ineffective, but it does not affect the normal refrigeration, and it can only be used on the spot (replacing the compressor is not as good as changing the whole machine).

6。The solenoid valve of the three-door three-cycle refrigerator has an abnormal sound--- which can be checked by touching the back cover when it is opened (the reinforced coil body may be used immediately).

7. Some models of the three doors are in the form of direct air cooling, and the wear of the circulating fan makes the sound louder--- the sound of the corresponding door will be terminated, and the small motor of the shaded pole will be used or replaced.

8. Poor heat dissipation due to some reason, heavy compressor operation caused by the rise of exhaust pressure, long running time and large power consumption--- improve heat dissipation conditions, (part of the quality problem, poor paste, separation of the heat pipe from the inner side of the box wall, resulting in poor heat dissipation).

It could also be a normal sound.

What sounds? Is it an unusual sound?

Why don't you talk when you ask a question?

Ask questions without a kiosk machine.

How often does it normally take a kiosk.

When the refrigerator is working normally, there is a little noise, but if the sound is loud or irregular, it means that the refrigerator is faulty and needs to be checked. Hehe! Wishing you health and happiness!

Generally speaking, the refrigerator will have a buzzing sound when it is started, and it will be quiet after starting, and the permanent refrigerator will also buzz when it runs because of the refrigerant, so it is recommended that your refrigerator add refrigerant, hoping to help you.

The refrigerator compressor will make a humming sound when it is working, and when the temperature drops to the specified temperature, it will automatically stop working. It's normal for the fridge to have a buzzing sound.

Why does the fridge keep buzzing.

Hello, not normal. The possible reasons are:1

It is not normal for the refrigerator to hum all the time, and the refrigerator compressor is running at intervals. 2.The uneven ground of the refrigerator or the unstable placement of the refrigerator is a common cause of the noise of the refrigerator, and the items placed on the refrigerator and its top will resonate when the motor is started, thus emitting noise.

3.Small things like bottle caps, lighters, gadgets, and many more that fall into the rear machine part of the refrigerator can also create noise. 4.

Refrigerant leakage, resulting in the temperature selling leather controller does not work, can not control the compressor shutdown, the compressor does not stop.

Summary. Dear, I'm glad to answer for you: Is it dangerous to keep buzzing in the refrigerator:

The humming of the refrigerator is sometimes a normal operating sound, but if it is constant or becomes louder than before, it may indicate a malfunction. Therefore, it is necessary to judge whether it is dangerous or not on a case-by-case basis.

Dear, I'm glad to answer for you: Is it dangerous to keep buzzing in the refrigerator: The buzzing of the refrigerator is sometimes a normal sound of fufupitanxing, but if it persists or the sound becomes louder than before the grip was touched, it may indicate a malfunction.

Therefore, it is necessary to judge whether it is dangerous according to the specific situation.

The following are some possible causes of humming: 1. Refrigeration compressor: The refrigeration compressor is one of the main components of the refrigerator, and the humming sound is often due to the vibration and noise generated by the refrigeration compressor when it is working, which is usually a normal phenomenon.

However, if the noise is too loud or frequent, the refrigeration compressor may need to be replaced or repaired. 2. Small debris: There are small debris on the inside of the refrigerator, such as food residues, paper scraps, etc., which causes a buzzing sound when the runner or fan blade is running.

This condition does not pose a threat to safety, but the inside of the refrigerator needs to be cleaned regularly. 3. Fan failure: The fan in the refrigerator may also cause a humming sound.

If the hum is always noticeable, try checking the fan yourself and having it repaired or replaced.

In summary, if the hum of the refrigerator is a normal machine running sound, it does not pose a threat to safety. However, if the sound is too loud, occurs frequently or affects the normal dust residual cracking activity, it is recommended to contact the manufacturer or professionals in time to assist in troubleshooting. At the same time, the refrigerator should be cleaned and maintained regularly during daily use, and debris should be avoided in the refrigerator.

Summary. Or the compressor works for a long time, and the lubricating oil enters other parts, resulting in insufficient lubricating oil inside the compressor, which will produce violent friction and make a sound. When foreign objects enter the refrigerator element, noise will also be generated, and the compressor will also suffer varying degrees of damage.

After hearing the abnormal noise of the refrigerator, the user should quickly close the refrigerator, wait for a period of time to open the refrigerator, if the abnormal noise still exists, it needs to be repaired as soon as possible.

Hello. Is it normal for the refrigerator to be buzzing all the time. Hello.

The "humming" sound emitted by the refrigerator is the sound made by the compressor in the refrigerator when it is working, which is a normal phenomenon. If the refrigerator makes an unusual noise, or even noise, then it is necessary to check whether the refrigerator is placed in a flat position. If there is oil leakage inside the compressor of the refrigerator, then the compressor will also make a loud noise when it starts.

Or the compressor works for a long time, and the lubricating oil enters other parts, resulting in insufficient pure oil in the internal lubrication of the compressor, which will produce violent friction and sound. When foreign objects enter the refrigerator element, noise will also be generated, and the compressor will also suffer varying degrees of damage. After the user does not hear the abnormal noise of the refrigerator, the user should quickly close the refrigerator, wait for a period of time to open the refrigerator, if the abnormal noise still exists, it needs to be repaired as soon as possible.

The fridge is buzzing dangerously all the time. Buzzing is not normal, although the refrigerator compressor does not make a sound when it is running, it does not exceed 45 decibels, and it will sound again after a while. On the contrary, the buzzing sound is continuous and loud, which may be caused by uneven placement of the refrigerator, damage to the thermostat or unfixed parts, in this case, contact the after-sales personnel to investigate and repair.
