What is the reason why Haier Refrigerator 215DF Adjustment Artificial Intelligence Sometimes The Com

If it doesn't work, it's not that the overload protector is faulty.

Use the ammeter to measure whether the compressor start-up and running current are normal (the starting current is generally about 5 8 times of the operating current), if the current is normal and the overload protector acts, the overload protector fails and should be replaced. Otherwise, the compressor is faulty.

Household refrigerator compressors run or stop automatically according to the set temperature. This is normal and there is no problem. The length of operation depends on the set temperature level, ambient temperature, how much is placed inside, the degree of sealing, etc.

When adjusting the compressor of artificial intelligence, if it does not work sometimes, it is natural that there is a problem, which needs to be checked by professionals.

I think the main reason why the Haier refrigerator sometimes doesn't work is that the motherboard inside is broken.

This is a professional question, I think you can take a look at the product manual, or you can call the merchant's customer service a**. If you really can't do it, you can ask the Haier refrigerator repair staff.

Harbin Xiang 215dnf mediates artificial intelligence, sometimes compressors work, sometimes do not work, the reason is that there is a problem with their contact.

And the refrigerator adjusts the artificial intelligence sometimes the compressor works sometimes does not work what is the reason, because after it reaches a certain temperature, it will stop.

First, the refrigerator compressor is not cold.

1.The problem that the refrigerator compressor does not heat up and not refrigerate may be caused by the failure of the refrigerator thermostat control;

2.The high-pressure output buffer pipe in the compressor is broken, or the screw fixing the tube is loose, resulting in the phenomenon that the high-pressure pipe does not exhaust and the low-pressure pipe does not suction, so although the compressor is running, it is not refrigerated;

3.If the internal temperature of the refrigerator does not drop, it may be that the capillary tube is blocked, resulting in the refrigerant not being able to enter the evaporator to evaporate and absorb heat, and the internal temperature of the refrigerator will not drop.

Second, the refrigerator compressor is buzzing all the time.

1.If the fridge emits a muffled humming electromagnetic sound, the possible causes of this phenomenon are:

1) The possible reason is that the grid voltage is too low, which makes it difficult to start the refrigerator compressor;

2) The connection points of fuses, sockets, plugs and other components and wires are loose, which will cause intermittent situations;

3) Insufficient or deterioration of capacitance in capacitors.

2.The refrigerator emits a heavy humming electromagnetic sound due to an overloaded compressor, which is caused by:

1) The refrigerator is affected by hot summer or other heat sources, resulting in an increase in ambient temperature and a humming sound;

2) Too much refrigerated and frozen food;

3) The refrigerator door is not closed tightly or the door is opened too many times;

4) Put the thermostat on strong cold 7 gear.

3.What is the reason why the refrigerator compressor is not working?

1.The refrigerator compressor is not working due to a power outage or poor contact;

2.It could also be that the compressor is not powered up. At this point, the temperature controller should be checked. It may be because the thermostat temperature bulb is leaking and the thermostat contacts are burned out.

3.It may also be that the motor unit of the compressor is burned out, and it only needs to be replaced with a new fuse in time to repair it;

4.It can also be caused by low ambient temperatures. When the ambient temperature is below 0, the compressor oil of the refrigerator thickens and the lubrication performance deteriorates.

At the same time, the condensing pressure of the refrigerator compressor is lower, and the refrigerant does not flow into the evaporator. If the refrigerator is forcibly used, not only will it not work properly, but it may also cause damage to the compressor.

It may be caused by the aging of the compressor, or the loss of the compressor cord head, resulting in the power failure of the compressor. It is also possible that the internal parts of the compressor are damaged, or the passing voltage is abnormal, causing the circuit to be burned. The cause of the problem is different depending on the location of the problem, and it needs to be detected by professionals.

1. First of all, see whether the power supply of the refrigerator is plugged in, because some refrigerator power plugs are loose, or the socket is out of power. Causing the refrigerator to lose power, at this time the compressor will definitely not work. If the refrigerator has power, the indicator light is on, and you can detect whether there is current passing through the joints on both sides of the compressor.

If the compressor is not fully connected to the power supply, it will not start. 2. If the internal parts of the compressor fail, it may be that the shaft is broken, or the internal parts are deformed and cannot rotate. There are also freezers in use, the fuse of the compressor is easy to be blown off, which is a common fault of the compressor, as long as the new fuse is replaced in time to repair, if the compressor is aging, the internal components are damaged, then it is best to replace the compressor.

3. Another reason is that there is a problem with the thermostat circuit of the refrigerator. The thermostat controls the temperature inside the freezer, and when the temperature is too high, the natural compressor will start to cool down as soon as possible. So if the thermostat fails and the temperature cannot be reported, the natural freezer will not start and the compressor will not work.

4. The voltage causes the compressor to fail to start. When the voltage is insufficient, the compressor does not have enough power and naturally cannot start. The above problems need professional maintenance personnel to detect and repair, do not disassemble the machine for inspection.

First, the power supply problem.

If the Haier refrigerator is not refrigerated, do not doubt the use problem or the quality of the refrigerator, but should first check whether there is a problem with the power supply and see if the power connection is normal.

Solution: Open the door of the refrigerator and observe whether the light in the box is on, or use an electric pen to test whether the socket is powered on.

Second, the compressor problem.

If the Haier refrigerator is not refrigerated, another reason may be that the compressor is not working properly. The compressor will emit a slight and vibrating motor sound when working properly. It may be due to a break in the high-pressure output buffer pipe inside the compressor or a loosening of the fixing screws of the pipe.

Solution: If the high-voltage output buffer tube is broken, it needs to be replaced in time; If the fixing screws are loose, then it is only necessary to re-tighten the fixing screws of the high-pressure buffer tube.

Third, the fan problem.

If the refrigerator is intercooled, check if the fan is working. Open the door of the freezer and press and hold the button on the edge of the box mouth with your hand to see if the fan is working, as the fan will cause the refrigerator to not refrigerate. In addition, too much food in the box will also affect the refrigeration effect.

Solution: If there is a problem with the fan, then replace it with a new one. At the same time, it is also necessary to reduce the amount of food stored in the refrigerator.

Fourth, the problem of refrigerants.

When the refrigerator has insufficient refrigerant or leakage, although its compressor is also running, there is no refrigerant evaporation and heat absorption in the whole refrigeration system, and of course, it cannot play the role of refrigeration and preservation.

Solution: If the refrigerant is insufficient, you need to add refrigerant to the refrigerator in time. If the refrigerant leaks, the leaking part needs to be welded before adding refrigerant to the refrigerator before a new refrigerant can be added.

There are basically the following reasons why the refrigerator compressor does not work for refrigeration

1.There was a leak in the refrigeration system, the refrigerant was gone, and the compressor was still running, but there was no refrigerant to work, so the temperature inside the refrigerator would not drop.

2.The high-pressure output buffer pipe in the compressor is faulty and broken, and it is also possible that the screw fixing the high-pressure output buffer pipe is loose, resulting in the high-pressure pipe not being able to discharge air and the low-pressure pipe not being able to absorb air. Therefore, the compressor is running but not cooling.

3.The capillary is blocked, and the refrigerant cannot enter the evaporator, and this situation does not refrigerate.

The refrigerator is not refrigerated and there are the following ways to check:

1.The refrigerator makes a sound and cannot be started: when the refrigerator is started, the compressor makes a sound, and the compressor does not work for about half a minute, because the voltage is too low. When the power supply voltage returns to its normal level, it will work normally.

Hello: 1, the compressor is the power source of the refrigerator, the compressor does not rotate, it will definitely not be able to refrigerate.

2. The reasons why the compressor does not rotate are:

Set in shutdown gear, damaged or deteriorated temperature sensor, short circuit of overheat protector, damaged compressor starter, damaged compressor, etc.

Haier, refrigerator. This problem occurs when the compressor does not work without refrigeration, and most of it is because the compressor starting capacitor is broken. Find a master to see if the starting capacitor is broken? If the compressor doesn't start, the capacitor doesn't work.

When the refrigerator compressor is not working and not starting, you should first check the contact status of the power supply, fuse and plug.

Secondly, check the temperature controller, the refrigerator compressor is affected by the thermostat, if the thermostat has a problem, the contacts can not be closed, the compressor will not work.

Another situation is that the ambient temperature is lower than the temperature of the gear controlled by the thermostat, and at this time, the compression time requires auxiliary heating to start the compressor, so if the thermostat is not properly adjusted, the refrigerator compressor may not work.

Finally, 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 there is no current on the compressor through the refrigerator The compressor does not work, and the operation is aborted, so as to maintain the compressor.

Possible causes and solutions: The refrigerator power supply is not plugged in properly, just plug in the power cord tightly; The motor unit of the compressor burned out and the fuse needed to be replaced; The circuit of the controller is faulty, and the compressor contacts need to be repaired; If the circuit voltage is abnormal, install a power regulator to solve the problem; The compressor's machinery is faulty and needs to be lubricated or repaired by a professional. Specific causes and solutions:

1. The refrigerator power supply is not plugged in or the refrigerator power cord is loose, the refrigerator cannot be well connected to the power supply, and the compressor cannot be started. If the problem is in the power supply, you need to plug the power cord of the refrigerator back in and plug it firmly to ensure that the refrigerator can fully receive power and the compressor can operate normally. 2. When the motor unit of the compressor is burned, the fuse of the compressor is blown out, which is a common problem that the compressor does not start, and a new fuse needs to be purchased and replaced.

3. If the controller circuit of the refrigerator fails, the general phenomenon is that the contact is overheated, burned, worn and other phenomena, which will lead to poor contact of the refrigerator compressor contact. The compressor contacts need to be removed for repair or replacement. 4. The circuit voltage of the refrigerator is abnormal, if the circuit voltage of the refrigerator is lower than the rated value, the motor of the refrigerator will not start, and it will make a "buzzing" sound.

The voltage needs to be measured with a voltmeter, and if the voltage is low, a power regulator can be installed to solve the problem. 5. The mechanical failure of the compressor will also lead to this problem. The problem of holding the shaft in the compressor is generally caused by the lubricating oil, which is caused by the blockage of the lubricating oil circuit, the interruption of the oil supply, and the increase of the viscosity of the lubricating oil due to the dirt in the lubricating oil.

The compressor cylinder is stuck because of the small gap between the piston and the cylinder or the thermal expansion relationship. If the fault caused by the lubricating oil, the lubricating oil is not enough to add the 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 strip on the back, find the relay that supplies power to the compressor, measure the voltage at both ends of the control pin is 12V, check forward, the drive tube base is extremely low, that is, the chip does not output work instructions. Artificially give this base a high level, the relay is engaged, the compressor works, and the refrigeration begins, making sure that there is no problem with the piping system.

2. The voltage sent by the power board to the display board is normal, and it is easy to misjudge that the control part on the power board is damaged. In fact, the most vulnerable to this fault is the door axis, and most of the brown wire is broken.

Disassemble the door shaft cover, you can see that all the wires are wrapped together with heat shrinkable tubes, remove the heat shrinkable tubes, and gently pull them one by one, and the broken wire will obviously pull out a section. Since the thread is fixed when the door is foamed, it is unlikely that it will be completely pulled out of the door to pick it up.

3. You can first connect a line on the outside, and then drill an oblique hole at a suitable angle around 4cm in the outer frame, which must be connected to the lower part of the top hole, and then polish the copper welding rod into a sharp end, clamp it on the electric drill as a drill bit, insert the foam layer at a suitable angle, open the electric drill when it encounters the middle plastic frame block, and soon open the plastic shelf, and then pass the soft wire through this hole, and finally seal the small hole in the outer frame with 704 glue, so that the fault is eliminated and does not affect the appearance of the refrigerator.
