The refrigerator light is on, and there is a humming sound when it is not refrigerated

1. Check the temperature controller. The operation of the refrigerator compressor is controlled by the influence of the thermostat, if the thermostat has a problem, the contacts cannot be closed, and the compressor cannot work. 2. The thermostat gear is too low.

The ambient temperature is lower than the temperature of the thermostat-controlled gear, which may cause the refrigerator compressor to not work. 3. Check the overload maintainer. The function of the overload maintainer is that when the temperature of the compressor shell is too high or the current on the compressor is too large, the contact of the overload maintainer jumps open and cuts off the circuit, so that no current on the compressor passes through the refrigerator The compressor does not work, and the operation is suspended to maintain the compressor.

4. The refrigerator compressor is damaged. If the refrigerator compressor is broken, it doesn't work and needs to be repaired or replaced. If the compressor hears a "click" sound when it is running, it is a metal impact sound coming from the inside of the compressor, indicating that its internal moving parts are loose and cause the parts to collide with each other.

If the compressor is in operation and hears the "hissing" airflow sound, it is caused by the detachment or rupture of the exhaust buffer pipe of the compressor, resulting in the high-pressure airflow sound; If you can hear the obvious "hissing" sound of the ball deflating when the compressor stops working, it means that the high and low pressure gaskets on the compressor valve plate are broken down, or the suction and exhaust valve plates are not tight and damaged, resulting in the airflow sound caused by the high-pressure end to the low-pressure end. If the compressor makes a "dangdang" sound during operation or at the moment when it stops working, it is caused by the breakage or fatigue deformation of the supporting spring in the compressor.

1. The refrigerator light is on, indicating that the refrigerator is energized, you can see whether your temperature setting is appropriate, whether the temperature setting is too high, and the refrigerator has not reached the starting point caused by no refrigeration. 2. If the setting is normal and you can hear the humming sound of the compressor running, it may be that the high-pressure output buffer pipe in the compressor is broken, or the screw fixing the pipe is loose, resulting in the high-pressure pipe not exhausting, the low-pressure pipe not suctioning, resulting in the refrigerator light not being refrigerated and humming. 3. Check the situation of the refrigerator starter, whether the temperature of the refrigerator compressor has not dropped down, and the overheat protector is working.

Suggested solutions: 1. If it is a problem with the setting, then you should adjust the set temperature of your refrigerator, generally refrigerated at 0-4 degrees Celsius, frozen at minus 18 or 20 degrees Celsius. 2. If the refrigerator light is on and there is a humming sound if the high-pressure output buffer pipe in the compressor is broken, or the screws fixing the pipe are loose, it is recommended to call the after-sales maintenance of the refrigerator** and ask a professional to repair it.

3. Look at the situation of the refrigerator starter, sometimes the overheating protector may be working if it is not refrigerated, and it is necessary to wait for a certain amount of time before the compressor temperature drops. 4. When using the refrigerator, it is necessary to regularly check the common functions of the refrigerator, pay attention to the maintenance of the refrigerator, and avoid problems such as the refrigerator light is not on and there is a humming sound.

1. If the power supply is fine, then you can listen to whether the refrigerator is moving, such as whether the motor is vibrating, if you can hear it, it means that the compressor is fine, if there is no movement, it may be that the motor is burned out. If the power cord is broken, you can open the refrigerator door and check whether the light in the box is on, or test the power cord with an electric pen to see if the cord is damaged.

2. If there is a lack of refrigerant, it should be from the refrigerator room not refrigerated, the current double-door refrigerator capillary outlet is advanced to the freezer to start circulation, the freezer evaporator can not be all frosted, the refrigerant is further insufficient, and the freezer is not refrigerated.

3. If the air duct is blocked due to the frost of the evaporator and cannot be melted, resulting in the refrigerator not being refrigerated, then the defrosting system should be checked at this time, it may be that the defrosting timer is faulty, or the heating pipe has burned out.

It could be an endoleak. Because the original internal freon is under pressure to break through, the leakage point leaks. Refrigerant leaks! The refrigerator cannot be directly refrigerated! First of all, check the leak, repair or replace the leakage, and then add refrigerant! It depends on whether the repair is repaired or replaced.

Compressor buffer tube rupture. At this point, the screw is in a loose state. Even if the compressor is still running, it cannot be cooled. Replace the buffer tubing with a new one.

1. What's going on with the buzzing of the refrigerator and not refrigeration.

1. It may be that the buffer pipe of the compressor is cracked, and the screws are in a loose state at this time, even if the compressor is still running, it cannot be refrigerated, and the user needs to replace the buffer pipe with a new one.

2. It may be a refrigerant.

Leakage, resulting in a lack of internal refrigerant, so the refrigerator can not be refrigerated, and users need to find professionals to add refrigerant.

3. It may be the capillaries of the refrigerator.

clogs, at this time the refrigerant has no way in the evaporator.

Internal heat absorption, so it cannot be refrigerated, and users need to ask professionals to dredge.

2. What are the ways to use the refrigerator correctly.

1. During the operation of the refrigerator, the user needs to regularly check the compressor and condenser.

The surface of the compressor and condenser should be cleaned to avoid serious dust accumulation, which will affect the use and life of the compressor and condenser. You know, if the compressor or condenser absorbs the dust on the surface, the heat dissipation effect of the refrigerator will be worse, and the cooling effect will also be worse, so you must be cautious.

2. There will be a variety of ingredients in the refrigerator, and some users will not be particular about putting the meat and vegetables that have not been packaged together, which will not only affect the taste of the ingredients, but also may lead to the breeding of internal bacteria, so when the food is put in the refrigerator, it needs to be packaged first to avoid cross-flavor.

3. Users need to clean the inside of the refrigerator regularly, and it is generally recommended to clean it at least twice a year, so as to ensure that the freshness of the ingredients is not affected, and the inside can be kept clean. In addition, it is important not to be too diligent in cleaning the refrigerator, because when cleaning, you need to take out the ingredients, and the temperature difference will be repeated and it will easily lead to deterioration.

Reason 1: The temperature in the refrigerator room is too high, resulting in an error in the refrigeration system, and the refrigerator will not be refrigerated without refrigerant, thus losing the refrigeration effect.

Reason 2: frosting in the evaporator, because the air-cooled refrigerator has only one evaporator, so when the evaporator frost cannot be melted, the air duct door will be blocked, which will affect the refrigeration system of the refrigerator.

Reason 3: The refrigerator has been used for too long, various mechanical aging of the refrigerator, and there are problems with the pipe or evaporator, which affects the refrigeration.

Reason 4: There is a problem with the compressor of the refrigerator, and the pressure of the return pipe of the compressor is too low, which will cause the compressor to fail to start, resulting in the refrigerator not being refrigerated.

Tip: If you can't handle it yourself, get a professional to inspect and repair it to avoid more damage.

Refrigerant loss due to damage and leakage in a certain part of the system pipeline, or ice jam failure in the refrigerator.

It is recommended to contact after-sales service or ask a professional for maintenance.

If there is no problem with the refrigerator, listen to the sound, whether the motor is vibrating, hear it, it means that there is no problem with the compressor, and if you don't hear it, it may be that the motor is burned out.

Check whether there is refrigerant or fluorine leakage and need to be re-added, or find a professional master to take a look, the refrigerator needs to be replaced for more than 9 years.

There are many reasons why the refrigerator has a humming sound and does not refrigerate, it may be a compressor failure, it is recommended to contact the after-sales service for maintenance after the power is off; It may be that the refrigerator lacks refrigerant and needs to be added; It may be that the pipeline transporting the refrigerant is damaged and needs to be repaired by a professional.

The hum of the refrigerator mostly comes from the compressor, evaporator and condenser. Squeezing between these pipes, and resonance can also cause the refrigerator to hum. In the summer, the temperature outside the refrigerator is too large, and the temperature inside the refrigerator is adjusted very low, and in the continuous work of summer, the thermometer head in the refrigerator can not feel the temperature change in the refrigerator, which will cause the control board to malfunction, resulting in the refrigerator buzzing.

Of course, the buzzing of the refrigerator is not all due to the internal part of the refrigerator, and the unstable placement of the refrigerator will also cause a buzzing sound during the placement process, and unstable will also cause the refrigerator to buzz.

It may be due to a rupture of the compressor buffer tube, which causes the screws to loosen, and the compressor is running but cannot be cooled.

Compressor buffer tube rupture. At this point, the screw is in a loose state. Even if the compressor is still running, it cannot be cooled. Replace the buffer tubing with a new one.

Buzz is the compressor turning again, your problem is either the lack of Buddha.

The refrigerator is a common household appliance in our household, which brings a lot of convenience to our daily life. However, refrigerators can also have some faults in use, and many people don't know much about them. So what's going on with the constant buzzing of the fridge?

What's going on with the constant buzzing of the fridge :

First of all, it may be that the thermostat of the refrigerator is damaged, and the temperature in the box cannot be identified, causing the refrigerator compressor to run non-stop, resulting in noise; Secondly, it may be that the refrigerant leakage of the refrigerator, the internal temperature of the refrigerator is high, so that the compressor has been working and produces noise; Finally, it may be that the refrigerator is not placed smoothly or there are too many items on top, resulting in high resonance noise.

What should be paid attention to in the daily use of the refrigerator:

1. Keep the heat source away from the refrigerator.

First of all, the refrigerator should be placed away from the heat source, because the refrigerator needs to emit a lot of heat when running, once the surrounding temperature is high, it will affect the heat dissipation of the refrigerator, and for a long time, it will not only increase the power consumption of the refrigerator, but also reduce the service life of the refrigerator.

2. Avoid sharing an outlet with other home appliances.

Secondly, the refrigerator is a high-power electrical appliance, and once it is started, it will produce a large current, so it is not recommended that two large electrical appliances share a socket to avoid excessive current, resulting in a short circuit or burning the socket. In addition, it is not recommended to share an outlet with the refrigerator, because if the distance is close, the refrigerator will emit electromagnetic waves when it is activated, which will also affect the use of other small appliances.

3. The idle time should not be too long.

Then the refrigerator cannot be used for a long time, because if it is not used for a long time, the pipes inside the refrigerator are affected by high temperature, which is easy to corrode, which will affect the service life. If you want to spend some time idle, you should also do a good job of cleaning it accordingly. In addition, the refrigerator should be cleaned regularly to avoid the growth of bacteria inside and affect the original taste of the food.

Qinghao must cut off the power supply first.

Hello, I am Xiaoyan, an electronic consultant, and I am happy to answer for you Please later, I am working hard to sort out the answer for you, and I will reply to you within 5 minutes

Hello dear, the refrigerator keeps buzzing the box is not refrigerating, what's going on? 1.The refrigerator keeps buzzing and the box is not refrigerated, the refrigerator compressor is not refrigerated, and the possible reasons are clogged stolen goods, refrigerant leakage, damage to the filter device, lack of fluorine, etc.

So, how do you check why your fridge is not cooling? The investigation method is as follows: observe whether the lights in the refrigerator are lit, or test with an electric pen, if the power connection is normal, listen to whether the compressor is working, under normal circumstances, the compressor will emit a slight vibration motor sound.

Let the refrigerator run for a few minutes before unplugging and listen carefully for the sound of liquid running inside the copper tube. If not, it means that the refrigerant in the system has leaked, or the compressor has lost its capacity. 2.

The refrigerator is not refrigerated, there is a sound, the refrigerator has been humming, the box is not refrigerated, and the pipe is leaking. Because the original internal freon is under pressure to break through, the leakage point leaks. Refrigerant leaks!

The refrigerator cannot be directly refrigerated! First of all, check the leak, repair or replace the leakage, and then add refrigerant! It depends on whether the repair is repaired or replaced.

Make up 100-150, change about 200-350. No matter how expensive it is, don't want it, it's only how much it costs to buy a new one. 2. Compressor failure.

If the unit is fine, there is no problem. It may be that the compressor is overheated, the protector is broken, and the compressor can be replaced. 3. Pipeline blockage.

The reason for the blockage of the pipes is most likely that the air in the repaired refrigerator is not pumped clean, and there is moisture inside.
