What is the reason for the humming sound in the refrigerator?

1.The refrigerator makes vibrating noise. The levelness of the refrigerator installation position is poor, and there is a gap between the anchor screws of some refrigerators and the ground.

When the compressor is started or stopped, the refrigerant cycle changes state, causing the refrigerator to vibrate and produce vibrating noise. Adjust the contact between the refrigerator anchor bolts and the ground and try to keep them as level as possible. Add a rubber or foam pad between the anchor bolts and the ground to reduce vibration.

2.The low humming electromagnetic sound emitted by the refrigerator is the main reason for this phenomenon: the grid voltage is too low and the compressor is difficult to start.

The connection points between fuses, sockets, plugs, and other components and wires are loose, resulting in intermittent properties. Capacitor capacity is insufficient or aging. How to eliminate electromagnetic hum:

Measure the supply voltage. When it is less than 20% of the rated voltage, an automatic voltage regulator should be installed. Check the connection and contact of fuses, plugs and sockets, and repair or replace those that do not meet the requirements; Replace the capacitor.

3.The refrigerator emitted a heavy humming electromagnetic sound. The compressor is overloaded, causing the refrigerator to emit a heavy humming electromagnetic sound.

Causes of this failure: Generally under the influence of hot summer and other heat sources, the ambient temperature rises. Too much refrigerated and frozen food.

3) The refrigerator door is not closed tightly, the air leakage is serious, and the refrigeration capacity is lost a lot. Too much power switch action, too many times to open the door, too long. The thermostat is placed on strong cooling variable 7.

Check if the compressor is overloaded by measuring the current and installing a pressure gauge. If the load is too heavy, reduce the refrigeration and freezing of food, reduce the number and time of door opening, remove obstacles, strengthen ventilation, and reduce the ambient temperature. Turn the temperature controller to Variable 4.

After the above treatment, the fault can be eliminated.

1. The refrigerator is not well placed.

If the refrigerator is "buzzing" when it is started or stopped, it is a pot that the refrigerator is not properly placed. When the refrigerator is uneven, the internal spring of the compressor is not unbalanced, which means that the refrigerator will vibrate with the spring and make a "buzzing" sound. 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 corners touch the ground, it is the best placement state.

What's going on with the "buzzing" of the refrigerator? The truth turned out to be this!

Second, there are items placed on the top.

In order to make efficient use of space, we often put small things on the top of the refrigerator. However, if you put too much stuff, it is easy to cause resonance and make a "hum" sound when the compressor is working. The solution is that removing the top of the refrigerator does not make it resonate, and naturally there is no noise.

3. The refrigerator pipeline is loose.

In the process of handling the refrigerator, because of the unprofessionalism of the porter, or the lack of carelessness, the pipes in the refrigerator are loosened, and the most loose pipe in the refrigerator is the exhaust pipe next to the compressor. If you want to solve this problem, you may need to find an after-sales staff to disassemble the refrigerator, and then stabilize the exhaust pipe.

Fourth, the partition is not fixed.

If the partition behind the refrigerator or the compressor base is not secure, it will also cause abnormal noise. We can try to press the compressor tightly with our hands, if the noise is significantly reduced, but when the noise increases when the hand is lifted, it is caused by uneven force on the compressor base fixed vibration damping rubber pad, loose bolts, and unstable compressor floor. Adjusting the bolts of the connecting part, tightening the connection, or replacing the washer that has lost its elasticity can effectively solve the problem.

The refrigerator is not in an even position. The 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.

There are items on top of the refrigerator. The refrigerator and the items placed on top of it 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.

Precautions for refrigerator use.

Generally speaking, the life of the refrigerator will be about 10 years, which needs to be determined according to the brand quality of the refrigerator, the materials used, and the maintenance habits of use.

Because the refrigerator needs to run for a long time, it is inevitable that the internal parts will age, so even if it can still be used, the noise, power consumption and sales volume of its operation are far less than when it was first used, so even if the refrigerator can still be used, it is recommended to replace the refrigerator in time, so as not to bring unnecessary safety hazards due to the aging of components and other reasons.

People's Daily Online-Scientific use of refrigerators, will you?

1. Generally a slight hum is a refrigeration process in the refrigerator. Do not worry.

2. Too much refrigerated and frozen food. Ice burial and consolidation have been in the process of refrigeration, and the refrigerator is overloaded.

3. There is a problem with the motor of the refrigerator, which causes noise during refrigeration.

Solution: 1. Check whether the compressor load is too heavy by measuring the current and installing the pressure gauge, if the load is too heavy, reduce refrigerated and frozen food, reduce the number of door openings, shorten the door opening time, remove obstacles, strengthen ventilation and reduce the ambient temperature; Set the temperature controller to 4th gear, and after the above processing, the fault can be eliminated.

2. It depends on the refrigeration performance of the refrigerator, if the refrigeration is good, and the refrigerator room even freezes, it means that the temperature of the refrigerator is too low or the thermostat is faulty, and the temperature of the refrigerator should be adjusted to the normal temperature grip slippery range or more bent skin to the new thermostat; If the refrigeration performance of the refrigerator is not good, it is mostly due to the damage and leakage of the system pipeline, and professionals should be asked to overhaul it, first detect the leak, then plug the leak, and then vacuum and fluoride.

3. If there is a "boom boom" sound in the refrigerator, and the sound is emitted in the running refrigerator compressor, this is the sound caused by the breaking or dislocation of the hanging spring in the compressor, which should be repaired in time.

4. There is a slight "buzzing" sound when the refrigerator is working, which belongs to the refrigeration work, especially in the summer, when there are too many items in the refrigerator, the refrigerator will be refrigerated from time to time to achieve the purpose of freezing, which belongs to the normal working range. If there is a serious humming sound, there is a problem with the motor, please go to the after-sales service.

Summary. 1. The refrigerator is not placed well, if there is a sound when the refrigerator starts or stops, it may be that the refrigerator is not placed properly, as long as you twist the bottom screw to adjust the height.

2. Place items on the top, if items are placed on the top of the refrigerator, it will also make a buzzing sound, so try not to put items on the refrigerator.

What's going on with the buzzing sound in the fridge.

1. The refrigerator is not placed well, if there is a sound when the refrigerator starts or stops, it may be that the refrigerator is not placed well, as long as you twist the bottom screw to adjust the height. 2. If items are placed on the top of the refrigerator, there will also be a buzzing sound, so try not to place items on the refrigerator.

3. When the refrigerator pipe is loose and handled, the refrigerator pipe Louis will also make a sound when it is loose.

The buzzing sound in the fridge can be caused by:

1.Compressor humming: The compressor of a refrigerator is the core component of the refrigeration system, and it will hum while working. This sound is usually normal, but if the sound becomes unusually loud or lasts too long, it may be a malfunction of the Chakut compressor.

2.Fan buzzing: The fan inside the refrigerator will run during the cooling process and will hum if the fan blades are loose or affected by dirt.

3.Refrigerator vibration: If the refrigerator is not stable or improperly placed, it will make a buzzing sound while running.

4.Refrigerator Duct Buzzing: The pipes inside the refrigerator may also make a buzzing sound, which is usually caused by the flow of refrigerant.

If the refrigerator makes an abnormal humming sound, it is recommended to contact a professional maintenance personnel in time for inspection and repair.

1. The refrigerator is not flat: If the refrigerator is not flat, the compressor will start to vibrate with the refrigerator when it is working, making a buzzing 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 debug 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. Resonance of items on the top of the refrigerator: 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 pipeline is 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.
