Is it normal for the refrigerator to buzz all the time, can you change the thermostat of your own re

Since the refrigerator keeps humming when it is powered on (the refrigerator system is working all the time), then it must be abnormal. If the refrigerator has passed the free warranty period and you have the technical and technical ability, you can buy a new thermostat to replace it. If you lack professional and technical ability, it is best to play Siemens refrigerator after-sales service**, please ask the after-sales service department to arrange professional service personnel to replace it.

The refrigerator hum has been working and can't stop, you have to consider whether it is a thermostat problem, excluding the thermostat is that the compressor has a problem, the refrigeration effect is not good, resulting in the refrigerator temperature can not be reduced and has been working, you can judge for yourself, touch the refrigerator on both sides is not hot, artificial is very hot, the refrigeration effect is good, the temperature sensor can not detect the temperature, resulting in the compressor has been working without stopping, in this case, two problems one is that the temperature sensor is broken, it should be the control board is broken, the control board is very low, It should be that the sensor is broken, because the sensor has been aging for a long time, resulting in the wrong resistance value, so that the control board can not control the compressor shutdown, if you have strong hands-on ability, you can disassemble it to see if the thermostat is good or not, if it is not good, it will be replaced by a professional, the sensor is not expensive, and the labor cost is OK.

The fridge is buzzing all the time, indicating that the compressor has been working. It's generally a matter of the thermostat. The thermostat can be changed at home, but not on your own. It is recommended to ask a professional maintenance personnel to check and repair it specifically. FYI.

The refrigerator sometimes buzzes, it may be that the refrigerator is not flat, it may be that the refrigerator is not well sealed, the refrigerator needs to be defrosted, or the refrigerator may be malfunctioning. After repairs, the refrigerator can still be used.

This situation in the refrigerator may be caused by the uneven position of the refrigerator and the ground, you can adjust the height of the refrigerator, the refrigerator has 4 screws, you can tighten these 4 screws, that is, adjust the height of the refrigerator. Because the refrigerator is not flat, the refrigerator will hum, and if you adjust the 4 screws at the bottom of the refrigerator, the sound will disappear and the refrigerator can still be used normally.

Because the refrigerator is not closed tightly, there are no children at home, and they may be too naughty, and they always like to toss the refrigerator, and the refrigerator will buzz. The solution is also very simple, turn off the refrigerator again, and the sound of the refrigerator will disappear. It is also possible that the sealing strip of the refrigerator is not tight, you can replace the sealing strip of the refrigerator, and after replacing it, the humming sound of the refrigerator will disappear.

If there are a lot of things piled up in the refrigerator, there is no room left, so there is a lot of frost in the refrigerator and the refrigerator needs to be defrosted. The solution is very simple, just turn off the power of the refrigerator, and then wait for the contents of the refrigerator to melt and start to defrost the refrigerator thoroughly. After the refrigerator is defrosted, this buzzing sound will disappear, usually do not open and close the refrigerator frequently, and defrost the refrigerator every once in a while, which will prolong the life of the refrigerator.

The refrigerator is always humming, it may be that there is a problem with the compressor of the refrigerator, if the door is closed again, but the refrigerator is defrosted, it still can't solve the problem, it is likely that the refrigerator is faulty and needs to be repaired. Looking for after-sales service for the refrigerator, you can let them come to the door for repair, or you can pull the refrigerator for repair, if it has not passed the expiration date.

Repairs are usually free of charge.

As long as the refrigerator can be used normally to keep fresh and keep warm, it is not a problem, this kind of sometimes buzzing sound is because the refrigerator has a very important part, is the fan in the process of working will make a little noise, this is a normal physical phenomenon.

It may be because the sealing is not very good, so this situation occurs; It can be used normally and will not have much impact.

This situation can be used, and this buzzing sound is emitted by the cooling fan.

The first point is that this situation is likely to be the refrigerator is broken, the second point may be that there is a leakage problem, so there will be this sound, you should check the line in time, the third point is that this situation is actually still usable, don't be too nervous.

The following tests can be done:

1. Push the refrigerator with your hands to see if it shakes. The place where the refrigerator is placed is uneven, and the refrigerator will also make a lot of noise. At this point, you can keep it level by adjusting the rotation button of the foot.

2. The refrigerator will buzz every once in a while when it is in operation. If it's not too loud, it's normal.

3. Check whether the screws of the rear protective cover are loose. There is a protective cover at the back of the refrigerator, and if the screws on it become loose, the noise will be correspondingly louder.

4. Check if there is a thick layer of ice in the refrigerator. If the sound of the refrigerator is indirect and regular, it may also be caused by the thermal expansion and contraction of the refrigerator.

5. If the sound is continuous and the noise is loud, professionals need to disassemble it.

It may be that the refrigerator is not flattened, or it may be that the compressor cover screw on the back of the refrigerator is loose. If the hum of the refrigerator is eliminated or reduced, it can be determined that the sound made by the cabinet is the sound of the refrigerator.

When the refrigerator is working normally, the compressor will work intermittently, which is a kind of humming sound, which is normal.

If you feel that the noise is too loud, it may be one of the following situations:

1.The refrigerator is not flat, it can be adjusted manually, and there are generally one or two feet under the refrigerator that can be rotated to adjust the level of the box.

2.The compressor cover screw on the back of the refrigerator is loose. It can be tightened using a recone.

3.The compressor connection pipeline resonates, in this case, the protective cover at the back needs to be disassembled, because of safety reasons, it is not recommended that the user repair it by himself, and can apply for after-sales on-site testing.

If there is a buzzing sound, it may be that the refrigerator is not flat, and it may be helpful to try to adjust the level with a level.

Lend it to you. If there is a model of your home, it is recommended that you change it.

Shock absorption on the line, there are adjusting screws, read the manual!

There are many reasons for the noise of the refrigerator, you can first compare the following situations to find the reason 1, the refrigerator is 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.

The main reasons for this phenomenon caused by the low humming electromagnetic sound emitted by the refrigerator are: 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 on-off and off-time; Capacitor capacitance is insufficient or deteriorates and fails. Elimination method of humming electromagnetic sound; Measure the power supply voltage, when it is less than 20% of the rated voltage, an automatic voltage regulator should be installed; Check the connection and contact status of fuses, plugs and sockets, and overhaul or replace them if they do not meet the requirements; Replace the capacitor.

The refrigerator emits a heavy humming electromagnetic sound, and the compressor is overloaded, causing the refrigerator to emit a heavy humming electromagnetic sound. Causes of the failure: Generally in the hot summer and the influence of other heat sources, resulting in an increase in ambient temperature; Too much refrigerated, frozen food; The refrigerator door is not closed tightly, there is serious air leakage, and the refrigeration capacity is greatly lost; Too many power switches, too many times to open doors, too long a time; The temperature controller is placed on the 7th gear of strong cooling.

By measuring the current and installing a pressure gauge, check whether the compressor load is too heavy, 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.

1. The refrigerator should be placed horizontally, and the heavy object should be hoisted down from the top of the refrigerator along the corner of the frame with a wire to adjust the balance of the refrigerator.

2. Put several layers of rubber gaskets of bicycle inner tube scissors on all four feet of the refrigerator to effectively absorb shock.

3. The four feet of the refrigerator must be firmly grounded, the front two feet can be rotated to press the ground, and the back two feet are fixed and unadjustable.

4. Push the two corners of the front of the refrigerator with your hands, and if the noise is reduced, pad the wood chips at the foot of the corresponding refrigerator.

5. The partitions, bottles and cans inside the refrigerator should be fixed and should not vibrate with the refrigerator.
