The refrigerator won t start, and it s gone again

If the sound returns after a while, it is normal, this is the refrigerator refrigerated evaporator.

The sensor plays a role in temperature control.

The refrigerator evaporator sensor is like a switch, and when the temperature reaches the set temperature, the sensor senses it and the compressor stops. This is with the air conditioner evaporation box temperature sensor.

Similar. The temperature sensor of the evaporation box is to prevent the temperature from being too low and freezing to cause hard damage, and the wind will become hot after freezing, which is very bad.

It can avoid such a thing, as soon as the temperature is low, the power will be cut off and the compressor will stop working.

If the refrigerator does not work, you must ask the maintenance personnel to check it.

Extended information: Refrigerator compressors.

Checks that do not start.

1.When the refrigerator compressor does not start, first check whether the power supply of your refrigerator is plugged in or whether the power supply of the refrigerator is loose, the refrigerator is not well connected to the power supply, and the compressor of the refrigerator cannot be started.

Solution: If the problem is in the power supply, plug the power cord of the refrigerator back into the power plug to ensure that the refrigerator can fully receive power.

2.The reason why the refrigerator compressor does not start may also be that the motor unit of the compressor is burned out, and the problem that will occur at this time is the fuse of the compressor.

Blowing, which is a common problem when the compressor does not start.

Solution: The refrigerator compressor fuse blows and the compressor does not start, so you need to purchase a new fuse and replace it.

3.If the controller circuit of the refrigerator fails, the general phenomenon is that the contacts are overheated, burned, worn and other phenomena, which will lead to poor contact of the refrigerator compressor contact.

Solution: Remove the contacts of the refrigerator for repair or replace the contacts of the refrigerator.

4.Check whether the circuit voltage of the refrigerator is normal, when the circuit voltage of the refrigerator is lower than the rated value, the motor of the refrigerator will not be easy to start, and at the same time make a "buzzing" sound.

Solution: Use a voltmeter first.

Measure the voltage, if the voltage is low, you need to buy a power regulator to increase the voltage value to make the refrigerator run.

5.A mechanical failure of the compressor can also cause the refrigerator compressor to not start. The problem of holding the shaft of the compressor is generally caused by the lubricating oil, the lubricating oil circuit is blocked or the oil supply is interrupted, and the dirt in the lubricating oil increases the viscosity of the lubricating oil; The compressor jams are due to the mating gap between the piston and the cylinder.

Small or thermal expansion relationship stuck.

Solution: If the fault caused by the lubricating oil, the lubricating oil is not enough to add lubricating oil, and the viscosity of the lubricating oil pipe and lubricating oil increases, the lubricating oil should be replaced. If the problem is that the compressor is jammed, it is necessary for professionals to repair it.

1. Check the power supply voltage at start-up, if the voltage is low, the compressor will not start, resulting in protection.

2 The compressor starter is defective and cannot be started, resulting in the overheating protector working.

3 The compressor is broken! The short circuit between the turns of the cylinder or coil causes the current to be too large, and the overheating protector works.

The fault of the refrigerator is mainly manifested in the fact that it stops as soon as it starts, and then starts again after cooling for a while, and it will be broken in two or three seconds, and there is a problem with the compressor starter, which causes the overheating protector to work. When the temperature drops to a certain point, it will restart, but it will jump again. There are two main reasons to consider, one is the failure of the starter, and the other is the failure of the overheating protector.

There is also a lack of voltage caused by the voltage, but the current voltage should be no problem, so the main fault point is on the starter and overheating protector, the biggest fault point is the starter, it is recommended that you call the refrigerator after-sales service ** repair.

1. Most of this situation is caused by the failure of the compressor, because if the compressor is not running properly, it will lead to no refrigeration. 2. There is also because of the thermostat inside the refrigerator.

The adjustable gear, or the inappropriate temperature, are the reasons for the poor cooling effect of the refrigerator. 3. There are also problems due to the failure of the starter or thermal protector, resulting in an abnormality when starting, and there will be a phenomenon that it will not ring for a while. Suggested workaround:

1. If it is determined that the compressor is not refrigerated due to failure, it is recommended to find some professional maintenance personnel to check the compressor, determine the problem after inspection, and then repair or replace it according to the specific problem, and this problem of non-refrigeration can be solved. 2. If the thermostat adjustment gear of the refrigerator is not suitable, or the temperature is too high or too low, it can be adjusted appropriately according to the temperature change of the external environment, and the refrigerator can be restored to the previous refrigeration state after adjusting to the appropriate gear. 3. After the starter or thermal protector inside the refrigerator fails, there is no way to operate normally, at this time, it is recommended to unplug the power supply first, contact a professional maintenance personnel, check the inside of the refrigerator, and repair it in time after finding the problem.

This is due to the fact that the sensor acts as a temperature controller. It's like a switch, and when the refrigerator reaches its set temperature, the compressor stops working. It is the same as the temperature sensor of the evaporation tank of the air conditioner, which can avoid hard damage caused by freezing when the temperature is too low.

If the wind becomes hot after the ice is frozen, it is not good to wait for the ice to melt before there is cold air, and the temperature switch can prevent this from happening.

If the noise stops for a short time, it is normal, because the refrigerator is equipped with a temperature control device, and when the temperature reaches the set value, the compressor will automatically stop running, and the refrigerator will not make a sound. However, if the noise stops for a long time, it may be that the internal temperature control system of the refrigerator is faulty, and a professional needs to be called to repair it.

Maintenance

1. It is best to clean the refrigerator shell every day, and wipe the refrigerator shell and handle with a slightly damp and soft cloth every day.

2. Cut off the power supply before cleaning the inner tank and take out the food in the refrigerator.

3. Dip a soft cloth in water or utensils dish soap, scrub gently, and then wipe off the dish soap with water.

4. Remove the accessories in the box and clean them with water or detergent.

5. When cleaning the refrigerator's "switches", "lights" and "thermostats", please wring out a rag or sponge.

The refrigerator is the best appliance for storing food at home, and the principle is to use the refrigerant cycle to achieve a hot and cold exchange to maintain the temperature of the storage room to maintain the freshness of the food. The design life of the refrigerator is generally about 8-10 years, and with the increase of the service life of the refrigerator, there will be different degrees of failure;

1. The thermostat is out of order. The thermostat is the control element of the refrigerator, which is used to identify the temperature of the storage room to control the start and stop of the refrigerator, and is also one of the important components of the refrigerator.

2. The starter is damaged. Due to the failure of the control of the refrigerator thermostat, the refrigerator is always open, and the starter is easy to heat up, resulting in the increase of internal resistance and the failure of the refrigerator to start.

3. The thermal protector is damaged. Due to the failure of the thermostat, the refrigerator is normally open, the compressor runs beyond the normal time, the temperature is abnormal, and the thermal protector is disconnected, which protects the safety of the compressor and the safety of the line.

4. The compressor is damaged. The compressor is one of the important parts of the refrigerator and the heart of the refrigerator.

You can refer to the above comparison, of course, after the refrigerator is repaired, it will not be as bad as the legend says, and it will increase power consumption, which is unfounded.

For the maintenance of refrigerators, it is best to find professionals to test for you, and now there are many home appliance repair stores around the country, and the technology of these stores is generally very good, you do not need to doubt it.

About the brand of refrigerator, refrigerator technology in China is relatively mature, the quality of the products produced by any manufacturer is basically very good, of course, it is not excluded that some products have design defects, it is best to choose some old brand manufacturers when buying, in order to get better service.

Regarding the cost of refrigerator maintenance, due to the particularity of some parts of the refrigerator, some parts are more expensive, of course, you don't need to worry too much, in fact, it is not expensive, and the maintenance is still very valuable.

The question is lit but no sound.

Answer 1, the temperature setting is unreasonable, the refrigerator light is on but there is no refrigeration, and there is no sound, which may be caused by the unreasonable temperature set by the air conditioner, generally there will be a switch that can adjust the temperature inside the air conditioner, if the temperature of the refrigerator is adjusted too high, the refrigeration effect of the refrigerator will be greatly reduced.

2. Lack of refrigerant When the refrigerator lacks refrigerant, it will also appear that the light is on but not refrigerated, especially for the refrigerator that has been used for a long time, it is necessary to add freon regularly to maintain the refrigeration effect, you can find a professional refrigerator maintenance master to add freon to the refrigerator, and the refrigerator can be restored to normal use.

3. Compressor damageCompressor damage is also one of the reasons why the refrigerator light is on but there is no refrigeration and no sound, and the damage of the compression of the air conditioner is a more serious situation, and the best way to deal with it is to replace the new compressor. The most common cause of compressor damage is a sudden power outage.

If you can't solve it, you need to contact a professional maintenance master to help you deal with it.

Question: How many gears is the best way to adjust in winter.

Answer: 3-4 or 5-6 in the freezer refrigerator in winter, the indoor temperature is relatively low in winter, and the temperature of the refrigerator and the fresh-keeping room is relatively small compared with the outside, so the air conditioner does not need to be adjusted to a very cold gear, so that the compressor can work for a long time to achieve the effect of freezing in the freezer, if the gear is adjusted higher, the phenomenon of thawing in the freezer will affect the preservation of food, so it is better to adjust the gear to 3-4 gear in winter;

"The refrigerator does not ring" means that the compressor stops refrigeration, if it is a short period of time to stop is a normal phenomenon, if the stop time is very long, (more than one hour) and the temperature in the refrigerator slowly rises, higher than the original set temperature, it may be that there is a problem with the control circuit or temperature control system of the refrigerator, you should contact the refrigerator maintenance personnel to help you check it.

It's good if you plug it in every five minutes, and the professional says you listen, because the starter suddenly loses power during operation, which causes overheating and needs to be cooled before it can be powered on, so that the power can be turned on.

The refrigerator will only sound when it is cooling, and after the refrigeration is completed, the temperature will be maintained for a certain period of time, and it will not sound during this time.

Reasons why the refrigerator does not start and solutions

Reason 1 for refrigerator not starting: power supply problem

If your refrigerator does not start, please check the power supply to ensure that the refrigerator power is normal, if the power supply is normal, see if the refrigerator light is on, if the light is on and the refrigerator has not started, you need to report for repair. Of course, if the refrigerator has a low-temperature compensation switch, it is necessary to see if the low-temperature compensation switch is turned on when the ambient temperature is lower than 16 degrees.

The second reason why the refrigerator does not start: the power supply voltage is too high

1. Under the normal ambient temperature (15--38), when the refrigerator starts, if the compressor makes a "hum" sound, the compressor stops working in about half a minute, which is due to the fact that the power supply voltage is too low (below 187V) and the compressor cannot be started.

2. If the compressor emits a "grace" sound, and then you hear a "pop" sound, this situation is caused by the power supply voltage is too high (higher than 242V) or the compressor has a long continuous working time; When the mains voltage returns to normal or the compressor housing temperature decreases, the refrigerator will work normally.

The third reason why the refrigerator does not start: the lack of oil in the moving parts of the compressor

At this time, the compressor will make a loud sound when it starts, and it will not be easy to start. At this time, the compressor can be filled with 30-50 ml of lubricating oil. In addition, the compressor has been out of service for a long time and has been stored improperly, which makes it difficult to start the internal parts due to moisture and rust.

Reason why the refrigerator does not start: other problems

The compressor was started again less than 3 minutes after the shutdown, and the high and low pressures in the system had not yet reached the equilibrium, which increased the compressor. In this case, it should be noted that after the shutdown, the door should be opened as little as possible, the opening time should be shortened, and it is not appropriate to put too much food for refrigeration, and not to put in items with higher temperatures, so as to ensure that the temperature in the box rises to the compressor starting temperature for more than 3 minutes, and does not affect the next start.

The above is the reason why the refrigerator does not start for you, I hope it can help you.

Summary. 1. The refrigerator is an intermittent operation of the equipment, during the refrigeration, the compressor will produce sound due to operation, and when the temperature reaches the predetermined temperature, it will stop operating and stop the sound. This is a normal phenomenon, as long as the noise is not too loud, it is generally fine.

1. The refrigerator is a device that operates intermittently, and when it is refrigerated, the compressor will produce sound due to operation, and when the temperature of the hall reaches the predetermined temperature, it will stop operating and stop the sound. This is a normal phenomenon, as long as the sound is not fast and the hail will be too large, and it is generally fine.

I'm still a little confused, can you be more detailed?

It may be that the area where the refrigerator is placed is uneven, resulting in a certain inclination angle of the refrigerator, which will also lead to the situation that the refrigerator will sound for a while and will not sound for a while, and the orientation needs to be adjusted in time. 3. There may be a problem with the starter on the left side of the compressor, and it will also cause the compressor equipment to fail to operate normally.
