What is the fault of Haier inverter air conditioner, the big board light flashes 19 times

- Is the air conditioner malfunctioning? With my 7 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.

First: When you encounter an air conditioner failure, you can go to the [air conditioner failure** network] to inquire, down to the brand and model of the air conditioner. Universal remote control** query can go to the universal remote control area for inquiry.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The air conditioner is not refrigerated or does not refrigerate.

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

If you still don't understand, it is recommended that you go to the [Air Conditioning Failure**Net] basic knowledge area and take a look at the maintenance cases to get started.

I hope you get better and better, and the new year will be smooth, all your wishes will come true, you will be healthy, and your family will be happy.

- Finally, I wish you all the best in your work, fix the air conditioner as soon as possible, and live happily ———

Hello, thank you for asking the company.

Hello, Haier fault ** is the press running out of step press out of position, from the outdoor unit module board to come, no other problems, find after-sales personnel to check whether the installation is firm.

You are welcome to ask the company questions again.

We wish you a happy work life

Summary. Hello, I'll come to your questions. If this happens, the voltage is definitely unstable. First of all, let's look at the issue of voltage.

Then, check the other boards for damaged resistors.

This may also cause the indicator light to flash frequently.

But this is to be tested by the instrument, and hopefully you will find a technical professional to do the test, even if you find the cause of the fault to make targeted adjustments and repairs.

I hope my answers are helpful.

What is the fault of the Haier inverter air conditioner's large board light flashing 19 times, and the outdoor unit of the Haier inverter cabinet does not work, and the red light of the motherboard flashes 19 times. What is the fault?

Hello, I'll come to your questions. If this happens, the voltage is definitely unstable. First of all, let's look at the issue of voltage.

Then, check for damage to the resistors in the other boards. In this case, it may also cause the indicator light to flash frequently. However, it is necessary to test through the instrument, and I hope that you will find a technical professional to conduct the test, even if you find the cause of the fault to make targeted adjustments and repairs.

I hope my answers are helpful.

It is also necessary to check for errors in the template communication of the outdoor and board power. Well, to find your after-sales service** to communicate.

Which board's resistor is damaged? Motherboard or driver board?

If this is the case, it is likely to be the driver board.

But the module communication fault flashes 4 lights?

This state should be low-voltage protection.

First of all, it is necessary to pay attention to the problem of the internal coil sensor and the underwear computer board. In this case, it usually shines 4 times. The temperature of the indoor evaporator exceeds 72 degrees to protect it.

Changing the driver board should solve the problem, right?

Well, there must be improvements, but the relevant problems have to be tested by professional personnel, and then they will be replaced with targeted adjustments.

In fact, two months ago, the forelimb was broken by the outdoor unit driver board, when the light flashed 4 times, and then I replaced a second-hand disassembled drive board (the condition is not very new), okay. But after two months of using the repentance cover, now the outdoor alarm machine is not working again, and the inspection light flashes 19 times when it is disassembled. There are only 18 fault diagnoses on the manual.

The flashing power light of the air conditioner may be due to the voltage instability or the power supply is not plugged in too much. When using the air conditioner, the user must first determine whether the voltage in the house meets the operation of the air conditioner, especially the use of high-power air conditioner. Before use, you should also pay attention to whether the power supply is plugged in firmly, if it is not plugged in firmly, you need to change the power supply or power strip.

Other reasons why the power light of the air conditioner flashes many times: 1. There is a problem with the connection of the internal and external unitsThe air conditioner cannot speak, so when there is a problem with the connection between the internal unit and the external unit of the air conditioner, it will be warned by the power light. The user first needs to check whether the connecting pipe of the inner and outer machine is stable and whether there are any leaks.

If so, it is advisable to replace it with a new one. 2. If the circuit fault air conditioner cannot be turned on, it will also be warned in advance by flashing the power light. If the nuclear combustion user finds that the power light flashes about 9 times after the air conditioner is turned on, he should immediately turn off the air conditioner and unplug the power supply, so as to avoid excessive power consumption and induce complete damage to the power circuit board.

3. Motor failureThe motor of the air conditioner is faulty, and most of them will be warned by the power lamp. When you turn on the air conditioner and find that the power light flashes many times, you need to call ** to ask the manufacturer's maintenance personnel to come to the door to deal with it, and do not deal with it yourself so as not to damage the motor. 4. When the power cord is damaged, the power light of the air conditioner will flash many times, and the new power cord should be replaced immediately to avoid **.

Summary. Hello, I have seen the question you asked, I am sorting out the answer, it will take some time to type. Please wait a moment

If there is such a situation, it should be that the resistor in the board of the plexus sensitive hole road is damaged, then it may be in the indicator light, and the resistance in this circuit board is damaged. Haier's national service seeps out power 4006999999, and contacts customer service to arrange for professionals to come to the site for maintenance.

Which board? Is it a motherboard or a driver board?

Driver board. Is the driver board bad, why not flash 4 times? It seems that flashing 4 times is a module failure!

Specifically, it still needs to be taken apart and checked, but it is possible.

In fact, two months ago, the outdoor unit driver board was broken, when the light flashed 4 times when it was opened, and then I replaced a second-hand disassembled driver board (the color is not very new), okay. But after two months, the outdoor unit is not working again, and the inspection light flashes 19 times when it is disassembled. Explain that there are only 18 fault diagnoses on the brief.

So listen to your judgment, it is possible that the driver board is broken again, because the dismantling goods I bought are very old, and it may not be used!

Changing the driver board should solve the problem, right?

You can try it first, buy one, replace it and try it, but you can't return it.

Haier conversions inverter air conditioner exterior panel indicator flashes 2 times, what's going on, hello dear, 1If the knob on the temperature controller is not dialed to the appropriate position, if it is dialed to a higher position, when the power is connected, the temperature in the air-conditioned room has not reached the upper limit of the set temperature (the temperature at the starting point), and the compressor cannot be started. 2.

You can check whether it is caused by a lack of fluorine, and there will generally be a shutdown display failure in about 10 minutes**3The power supply used by the air conditioner is too low, and when the voltage is less than 10% of the single-phase normal voltage (220V), i.e. 198V or below, it is difficult for the refrigeration compressor in the air conditioner to start4Voltage instability:

If the voltage of the shelter is not very stable for some reason, then when using the air conditioner, there will be a failure due to the unstable voltage, I hope it can help you. If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

Summary. What is the fault of Haier's air conditioner running light flashing 2 times, I am glad to answer for you1、The running light of the air conditioner is flashing, most likely because of the inability to communicate normally between indoor and outdoor air conditioning equipment. The reason may be that there is a magnetic field from the outside world that interferes with this, and the fault can be detected by the display board of the air conditioner.

2. When the current is overloaded, it will also cause the air conditioner to flash, sometimes the voltage at home is too high and the air conditioner will be overloaded, which is the air conditioner will start the self-protection system, and the indicator light will be flashing all the time, and accompanied by the phenomenon of turning on and off. 3. When there are some faults or problems in the refrigeration or heating system, the air conditioning running light will also keep flashing, which is to remind the air conditioner that it is faulty and should be repaired in time. Hope it helps!

Hello, dear dear, I am happy to answer for you, your question helps you to inquire: Haier air conditioner power light flashes 9 times, so the signs are as follows: 1. The refrigeration area of the room is too large, so that the air conditioner cannot be shut down; 2. The outdoor unit of the air conditioner is placed in a very hot place; 3. The fan speed of the outdoor unit is too slow, and the heat dissipation is poor; 4. The fluid valve and air valve of the new air conditioner have not been opened; 5. Misoperation of the pressure switch; 6. The high-pressure setting value of the air conditioner is incorrect; 7. When it is very hot in summer, due to too much Freon refrigerant, the high pressure is overrun; 8. Due to the long-term operation of the special constant temperature and humidity precision air conditioner in the computer room, the dust and putty in the environment are deposited on the surface of the condenser, which reduces the heat dissipation effect; 9. The axial fan motor of the air conditioning condenser in the computer room is faulty; 10. The power supply voltage of the special constant temperature and humidity precision air conditioner in the computer room is low, resulting in insufficient output voltage of the 24V transformer; The 24V AC contactor in the condenser cannot work; 11. There may be residual air or other non-condensable gases in the air-conditioning system of the computer room; 12. The P66 central briquetting contact of the air conditioner is loose; 13. The minspeed or adjustment of the special constant temperature and humidity precision air conditioner in the computer room is incorrect; 14. The fan bearing of the air conditioner is faulty, abnormal noise or stuck, solution:

1. Generally, the freezer is equipped with a full set of protection devices, when the freezer machine has a high-voltage alarm, it will automatically start the protection device, and the corresponding fault indicator will be on. 2. At this time, the refrigeration unit is shut down and does not run, and the operator needs to solve it through the following methods. First of all, if there is a high-pressure alarm in the water-cooled freezer, it is mainly related to the cooling water system, and the water-cooled freezer provides circulating cooling water through the cooling water tower.

3. If you forget to open the cooling water valve when you use it, resulting in the cooling water can not be circulated to the chiller, there will be a high-pressure failure, and you should check whether the cooling water tower is faulty and cannot be safe.
