The fridge is buzzing all the time, could it be that something is wrong?

Refrigerators rely on refrigerant refrigeration, and any refrigerator will emit the sound of refrigerant flow or eruption in the operating system, but due to the different structure, principle, etc. of the refrigerator, the sound volume will also be different. After the refrigerant enters the evaporator, it is throttled and depressurized by the capillary, due to the small diameter of the capillary, the flow rate of the refrigerant in the capillary is very fast, because when the evaporator enters the diameter of the evaporator, the refrigeration system will form an eruption sound at the capillary outlet, which is the normal sound of the refrigerant flow and has no effect on the refrigerator.

It is normal for the refrigerator to make a clicking sound when it starts, because the refrigerator is pulled off by relay armor when it starts, and the noise when the refrigerator is working is that the high-pressure liquid soda is sprayed into the low-pressure evaporation tube through the capillary. It's cheap and expensive on the market. The difference is in the compressor.

A good refrigerator compressor is of very stable quality and can last for many years, while a cheap compressor will be even worse. After all, how much you're going to pay. In some old direct refrigeration refrigerators, due to the long use of the compressor, in the above two cases, the refrigerator refrigeration effect will be abnormal, but if the refrigerator refrigeration is not abnormal, there will still be "tinnitus" for the following reasons.

The compressor will start vibrating and humming with the refrigerator when it is working. This is all due to the slamming of the refrigerator's feet on the floor. If your fridge is always buzzing, make sure the fridge is not flat.

In order to make efficient use of space, we often put small things on top of the refrigerator. But if you put a lot of things, it is easy to cause resonance and make a "tinnitus" sound when the compressor is working. This solution greatly improves our quality of life.

We all know that the fridge needs to be opened, and in order for the refrigeration cycle to work, it needs to be opened frequently, but sometimes after using it for a while, how about the fridge buzzing? These three situations are the most common and many people don't know about them!

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The buzzing sound, maybe aging, right? Let's go to the furniture repair shop and take a look at the electrical repair shop.

The reason for the humming sound of the refrigerator: because the thermal stress of some refrigerator raw materials has not subsided. As the use time increases, the thermal stress of the raw material gradually disappears, and the possibility of such noise is reduced.

The refrigerator has just been defrosted, and the temperature in the box is uneven. When the refrigerator door is opened, the evaporator of the air conditioner in the box is heated suddenly. A few minutes after the refrigerator is running or turned off, the temperature of the condenser and the air conditioner evaporator is relatively large.

After the refrigerator is used for more than half a year or a year, because of the running-in period of the human body in the internal structure of the refrigeration compressor, the void expands, and the noise also rises.

For example, in a high temperature environment, a thick layer of frost will grow on the refrigeration boundary layer of the refrigerator, which will cause the refrigerator not to shut down, which is caused by the temperature adjustment of the refrigerator temperature controller is too low or the storage part of the ingredients in the refrigerator is wrong, and the refrigerator is opened too often. For example, in hot weather, the temperature controller of the refrigerator will also fail, and then the refrigerator will not shut down, the main reason is that the temperature sensor head of the temperature controller can not understand the temperature transition of the internal structure of the refrigerator and the common fault of the control circuit board. If the natural ambient temperature around the refrigerator exceeds 32 degrees, the refrigerator is prone to not turn off, which is caused by the low efficiency of the refrigerator refrigeration compressor or the low cooling capacity of the air conditioner.

Refrigerator cleaning: Always remove the dust on the back or bottom of the refrigerator condenser and refrigeration compressor, and pay attention not to use a damp rag to wipe the dust on the refrigerator and refrigeration compressor. When the refrigerator is out of use for a long time, first cut off the power supply, take out all the food in the box, clean the inside and outside of the cabinet, and open the cabinet door for a few days to make the box dry enough and dissipate the odor in the refrigerator.

Inspect the drains. If the drain pipe is blocked, water will leak into the refrigerator. You have to poke the drain pipe with a thin wire to remove the items that have accumulated on the drain pipe.

Instead of neglecting the cleaning of the door seal seal, use a 10 times water dilution to moisten the bleach with a soft-bristled toothbrush, and finally rinse the bleach with tap water. The seal strip stain is easy to age, which will endanger the airtightness of the refrigerator and increase power consumption.

It may be that there are items on the top of the refrigerator, it may be because the refrigerator is not neatly arranged, or it may be the reason for the failure and aging of the refrigerator compressor.

It may be because the place where the refrigerator is placed is uneven, so this situation will occur.

It may be because the voltage is unstable, there are too many double beans on the inside wall of the refrigerator, the placement is unbalanced, and there are too many things on the refrigerator, all of which can cause the refrigerator to hum.

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.

1. Frosting

When exposed to high temperatures, a thick layer of frost will form on the walls of the refrigerator compartment, which will cause the refrigerator to not stop. This is caused by the temperature regulation of the refrigerator thermostat being too low or the incorrect position of the food stored in the refrigerator, as well as the refrigerator being opened too many times.

2. The thermostat is out of order

When in hot weather, the thermostat of the refrigerator will also fail, resulting in the refrigerator not stopping, the main reason is that the thermostat thermostat head can not feel the temperature change inside the refrigerator and the fault of the control circuit board.

3. The power is too small

If the ambient temperature of the refrigerator exceeds 32 degrees, the refrigerator is prone to non-stop, which is caused by the low power of the refrigerator compressor or too little refrigeration capacity.

Refrigerator maintenance method:

1. If you clean the inside of the refrigerator regularly After the refrigerator has been used for a long time, the smell in the refrigerator will be very bad, and even bacteria will breed and affect the original taste of the food. Of course, the refrigerator with the function of deodorizing and sterilizing photocatalyst will make the air in the refrigerator fresh and clean, without peculiar smell, and you don't need to clean the refrigerator often.

2. Don't put household appliances together in the refrigerator. The heat generated by the appliances in your home can increase the burden on your refrigerator and increase your electricity consumption. Also stay away from heat sources and avoid direct sunlight, as this heat can also put a strain on the refrigerator.

In short, when it comes to placement, we must keep the refrigerator away from the heat source and fully dissipate heat.

3. If the refrigerator is not used for a long time, you can unplug the power plug of the refrigerator, and then get all the things in the refrigerator out. Open the refrigerator pure pants door and wait for the frost to melt, defrost please do not sharpen, the evaporator is made of aluminum and is easy to leak. I wipe the refrigerator clean from the inside out with a clean cloth.

There must be no water. The door seal should be padded with paper or other things to prevent the door seal from sticking to the box; If you don't use it for a long time, you can apply some lime powder to the door seal.

The fridge is always buzzing for the following reasons:

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.

4. The thermostat is damaged, does not work, and cannot control the compressor to shut down. The refrigerant leaked, causing the thermostat to not work and the compressor to run non-stop.
