Why does the refrigerator stop cooling when it is powered off and then powered on?

After the refrigerator is powered off, it will not be refrigerated, which means that there is a problem with your refrigerator, because the refrigerator is not refrigerated, there are only two reasons, one is that the temperature you set is reached, and the other is that there is a problem with the compressor of the refrigeration equipment.

1.If the power supply is cut off and the power is turned on immediately when the refrigerator compressor is working, the compressor cannot start to work at this time, because the compressor is cut off when the power supply is working, and the pressure difference between the two ends of the pipeline is very large.

2.In order to prevent the compressor motor from burning out due to the rapid increase in working current and rapid increase in temperature due to the failure to start, the compressor is designed with a thermal protector, when the motor temperature rises to a certain range, the protector will trip and cut off the power supply to protect the compressor motor from being burned.

Including air conditioners, after cutting off the power supply, it should be turned on after 3-5 minutes, and now many refrigerators or air conditioners are specially designed with a delay protection circuit.

If the refrigerator compressor is refrigerating, the power is cut off and the power supply is restored immediately, the compressor will not act immediately, because the thermal protector in it works, and it will not be restarted until at least five minutes later, because the pipeline pressure is relatively large when the sudden shutdown occurs, and the compressor will burn out due to excessive current if it is forcibly started.

Hello, if the power is turned on again after the power is off, it may be a momentary power failure that causes a short circuit. You can find a maintenance person to take a look.

If it is a direct-cooling refrigerator, it is likely that there will be internal leakage due to long-term power failure, and the radiator will have a loophole and the refrigerant will leak. The maintenance cost is high, and the refrigerator can basically be scrapped.

Of course, there are other possible causes that need to be checked to determine.

A normal refrigerator won't. How can it be coincidental to the moment of damage when "power is off and then power on"? It's best to find an expert to check it, it's the operation of ** that has a problem, and generally this kind of "coincidence" is difficult to happen.

Maybe there was something unexpected about the operation of **? Hopefully your fridge isn't damaged.

Normal no, it may be caused by a power outage.

Common reasons: 1. If it is suddenly not refrigerated, it may be a control problem, and you can change the compressor protector first. 2. If the refrigerator is turned on again after being used for a period of time, but it is not refrigerated, it may be a power supply problem, see whether the connection of the power supply is normal, and whether the plug is powered on and plugged in steadily.

Other reasons: 1. Recall that when it was not broken before, whether there was any force in the state of running the refrigerator, handling or closing the door, etc., if so, it may be that the press is stuck, and you can also continue to beat the compressor from all directions, and then power it on, and knock it on continuously, and try it several times in a row. The worst-case scenario is that the compressor breaks.

2. Refrigerant.

Problems, running out of refrigerant in the refrigeration system or leaking can also cause the refrigerator to not refrigerate. Regarding the refrigerator is not refrigerated, to completely solve it, you need to contact the refrigerator after-sales staff, let them come to check the specific situation, and the professionals will give the corresponding treatment plan, which is best not to operate it yourself. Expand your knowledge:

Refrigerator maintenance: Regularly check whether the refrigeration parts of the refrigerator are dirty, such as compressors and condensers.

If these parts are covered with dust, it will affect the heat dissipation of the refrigerator. After the refrigerator is used for a long time, it will have a peculiar smell, and there will be a lot of bacteria in the refrigerator, so be sure to clean it regularly, such as twice a year.

There are two main reasons why the refrigerator does not refrigerate, which are as follows:

1. The compressor cuts off the power supply when working, and immediately energizes it, because the pressure difference between the two ends of the compressor is very large, and the compressor cannot start working at this time. Therefore, in the future, the refrigerator compressor is working to cut off the power supply, and after a few minutes, wait for the pressure difference between the two ends of the compressor to slowly return to balance before turning on the power supply, so that the compressor can start working smoothly.

2. If the refrigerator is not refrigerated and the power supply is cut off, after a period of time, the refrigerator can be refrigerated, it is estimated that there is an ice plug fault in the refrigerator system pipeline, even if it can be refrigerated for a short time, but after a period of time, there will be ice blockage, so that the refrigerator will not be refrigerated, you must contact the after-sales service or ask professionals to overhaul and dry the system pipeline.

The refrigerator is not refrigerated, and the power is turned on and refrigerated after half a day of power failure, in this case, the first thing that should be considered is whether the compressor of the refrigerator is missing or whether the temperature sensor of the indoor unit is abnormal, or the whole line is not in good contact.

Compressor thermal protection, shutdown, refrigerator compressor has a thermal protection fuse, when the temperature exceeds 50 degrees or 45 degrees, the compressor will automatically power off, protection shutdown.

After two hours, the compressor's top cover protector will automatically reset and the compressor will operate normally.

The refrigerator is not refrigerated, and the reason why it is refrigerated after the power is off may be that the internal temperature of the refrigerator is too high, or the frost inside the refrigerator is more serious, you can check it.

When the refrigerator is working normally, the power is cut off and then the power is sent again, and the motor is difficult to start due to the high internal pressure. , the overtemperature protection trips due to the large starting current. The power supply time is long, and the pressure before and after the compressor is equalized is easy to start, so it can start refrigeration again.

It should be the intermittent refrigeration of the refrigerator caused by the excessive moisture content of the refrigeration pipeline and the ice blockage of the pipeline.

There is refrigerator refrigerant.

Leakage, poor contact of the refrigerator's power plug, low ambient temperature, and interruption of the compressor operation. For specific reasons, you can contact professional maintenance personnel for inspection and maintenance.

Other reasons. 1. It may be that the refrigerator refrigerant leaks, and the refrigerant will be insufficient when restarting again, if the indoor temperature is low at this time, the temperature of the refrigerator should be adjusted to 7, and the temperature compensation switch should be turned on;

2. Or it is a power supply problem, a power outlet.

If there is no electricity, the power plug of the refrigerator is not in good contact, as long as the power supply is plugged in, it can be solved, if the power cord is broken, then the power cord needs to be replaced;

3. It may also be that the ambient temperature is low, and the low temperature switch of the refrigerator should be checked to see if it is turned on. When the ambient temperature is lower than the normal starting temperature of the temperature controller, the temperature controller cannot be forcibly turned on if the low temperature switch of the refrigerator is turned off. Because of the refrigerator thermostat.

It is installed in the refrigerator, and the temperature of the refrigerator does not stop if it does not reach the temperature required by the thermostat.

4. If the refrigerator compressor.

The compressor cannot work immediately, because the thermal protector in it works, and it can not be restarted after at least five minutes, because it is a sudden shutdown, the pipeline pressure is relatively large, and the compressor will burn out due to excessive current if it is forcibly started.

The reasons why the refrigerator does not refrigerate after it is powered off are as follows:

1. Power supply problems. Power outlets.

If there is no electricity and the power plug of the refrigerator is not in good contact, it will cause the refrigerator to not be able to refrigerate normally, as long as the power supply is plugged in. If the power cord is broken, then the power cord needs to be replaced, and at the same time consider cleaning up the rats in the house.

2. The ambient temperature is low. When the ambient temperature is lower than the normal starting temperature of the temperature controller, check whether the cold switch of the refrigerator is turned on. Only when the low temperature switch is turned on can the temperature controller be forcibly turned on. Refrigerator thermostat.

It is installed in the refrigerator, and the temperature of the refrigerator does not reach the temperature required by the thermostat, so it is not refrigerated.

3. The limit temperature has been reached. If the compressor does not stop around the clock, the freezer may produce refrigerant.

Extreme refrigeration temperature. Most of this phenomenon occurs in air-cooled refrigerators. The reason is the cold room evaporator.

The defroster is broken, creating an ice blockage. It cannot be ruled out that the air cooling fan is broken, and there are too many items in the refrigerator to block the air outlet, causing poor cooling effect.

4. The temperature control adjustment does not match the ambient temperature. Generally, the temperature of the refrigerator room is 4-10 degrees Celsius. The higher the number of the temperature controller, the lower the temperature, the higher the number in the summer and the smaller the number in the winter.

In addition, the refrigerator door is often opened, and there are many items in the refrigerator, resulting in the refrigerator not being refrigerated or the refrigeration effect is not ideal.

5. The compressor does not work. The compressor's high-pressure output buffer tube is broken, the screws holding the high-pressure buffer tube in place are not tightened, or the compressor fuses due to the high operating temperature for a long time.

If the fuse is blown, it is easy to cause the compressor to not work.

1. It may be a refrigerator refrigerant.

The leak causes the refrigerator to be powered on and not refrigerated after the power is off. 2. It may be that the low ambient temperature of the refrigerator causes the refrigerator to be powered off and not refrigerated. 3. It may be that the fan of the refrigerator is not operating normally, resulting in the refrigerator not being refrigerated after the power is off.

4. It may be that there is a problem with the buffer tube that causes no refrigeration. Suggested solutions: 1. In this case, you only need to find a professional maintenance personnel to add refrigerant to the refrigerator.

2. When the ambient temperature is lower than the normal starting temperature of the temperature controller, check whether the low temperature switch of the refrigerator is opened. Refrigerator thermostat.

Installed in the refrigerator, the temperature of the refrigerator does not reach the temperature required by the thermostat and will not be turned on. 3. Open the refrigerator door of the refrigerator, press and hold the small button at the edge of the box mouth with your hand to check whether the fan is working at this time, and the fan will not work will also cause the refrigerator to not refrigerate. 4. The high-pressure output in the compressor is slowly broken, or the screws fixing the pipe are loose, which will cause the high-pressure pipe to not exhaust and the low-pressure pipe to not suction, which will cause the compressor to run but not refrigerate.
