What is the reason for the defrosting and fault light of Gree air conditioner when refrigeration?

- 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 ———

n You should ask the store where you bought the air conditioner.

Summary. The reason for the shutdown after defrosting is shown by the refrigeration of Gree air conditioner: 1

When the ambient temperature is too high, the sun is direct and there is no shading object, the outdoor unit has poor ventilation and a mesh cover or the wall is blocked in front of the outdoor unit, the air conditioning heat cannot be blown out, and the temperature is too high, the compressor will automatically start the protection and stop working to avoid damage to the compressor. 2.High pressure relay action, such as the condensing pressure is too high, so that the high pressure relay action stops the operation of the compressor.

3.Low-pressure relay action, such as insufficient refrigerant in the refrigeration system, resulting in the compressor suction pressure is too low, so that the low-pressure relay action stops the operation of the compressor. 4.

The long-term use of the air conditioner causes the aging of the internal valve plate of the compressor, resulting in the decrease of the transmission power of the compressor, resulting in the poor refrigeration effect of the air conditioner. The air conditioner refrigeration is normal, but the air conditioner filter has not removed the dust for more than half a month, and the dust blocks the filter, resulting in a decrease in circulating air volume.

Hello dear, glad to answer for you. Pro-Gree air conditioner cools down after defrosting.

The reason for the shutdown after defrosting is shown by the refrigeration of Gree air conditioner: 1When the ambient temperature is too high, the sun is directly exposed to no shading objects, the outdoor unit is poorly ventilated, there is a mesh cover or the wall is blocked in front of the outdoor unit, resulting in the heat of the air conditioner cannot be blown out, and the temperature is too high, the compressor will automatically start to absorb the chaos protection, stop working, and avoid damage to the compressor.

2.High pressure relay action, such as the condensing pressure is too high, so that the high pressure relay action stops the operation of the compressor. 3.

Low-pressure relay action, such as insufficient refrigerant in the refrigeration system, resulting in the compressor suction pressure is too low, so that the low-pressure relay action stops the operation of the compressor. 4.The long-term use of the air conditioner causes the aging of the internal valve plate of the compressor, resulting in the decrease of the transmission power of the compressor, resulting in the poor refrigeration effect of the air conditioner.

The air conditioner refrigeration is in the hole, but the air conditioner stool filter has not removed the dust for more than half a month, and the dust blocks the filter, resulting in a decrease in circulating air volume.

"Suddenly it doesn't work and the running indicator and defrost indicator flash at the same time" This is a malfunction of the air conditioner; You can determine the location of the fault based on how often the running and defrost indicators flash at the same time. The fault display method given by the air conditioner of different manufacturers is different, and you can check the manual to find out the reason.

Since the main control board of the air conditioner has been found to be faulty and alarmed, it will no longer let you operate, so the remote control is still unplugged and restarted.

Since your air conditioner is suddenly not working, it is recommended that you check the starting capacitor of the outdoor unit. In the high temperature season, the capacitor of the air conditioner is prone to dry out and take effect for a long time.

The air conditioner is running and the defrost light is flashing all the time without cooling.

The tube temperature sensor on the evaporator is broken.

The temperature resistance value of the tube has changed, so that the computer board detects a false signal and thinks that the internal machine is icing. Therefore, the defrost red light has been flashing rapidly.

If you understand electronics, go to the electronics market to buy a tube temperature sensor, its resistance value is 10k, **15 yuan. If you ask the maintenance department to repair, **70 yuan.

What is the reason why the air conditioner is running and defrosting suddenly flickering and not cooling.

If the refrigeration (refrigerant) is insufficient or missing, the solution is to check the leakage and make up for the refrigeration. That is, the refrigeration is restored.

What does it mean that defrosting is being displayed on the air conditioner.

The defrost on the air conditioner is because the air conditioner has turned on the defrost mode. In defrosting, the air conditioner may produce frosting phenomenon when cooling and heating, such as the air conditioner frosting after the defrosting is not timely, it will affect the use of the air conditioner.

The principle of air conditioning defrosting is that when the defrosting sensor senses that the outside temperature is lower than a certain temperature, it will transmit the signal to the control board, and then the control board will transmit the defrosting signal to the relevant components for defrosting, and then the defrosting controller controls the reversing direction of the solenoid steering valve, so that the heat of the air conditioner is reversed to the external unit, and the heat is released to the surface of the evaporator to defrost.

Extended information: If the air conditioner is not defrosted in time after frosting, it is easy to produce the following adverse consequences.

1. Block the passage between the fins to increase the resistance of air flow;

2. Increase the thermal resistance of the heat exchanger, and reduce the heat exchange capacity;

3. The evaporation temperature decreases, the energy efficiency ratio decreases, and the operation performance of the air conditioner deteriorates until it cannot work normally.

Hello, the reason for the defrosting of the head of the Gree air conditioner: 1. It means that in winter, the outdoor temperature will be relatively low, and some frost will be produced on the heat exchanger of the outdoor unit, which is what we call the frost layer. 2. And in order to avoid the impact of these frost layers on the use of the air conditioner, the air conditioner itself also needs to be defrosted, and the air conditioner will be defrosted at this time.

3. Air conditioning defrosting can improve the heat exchange effect of air conditioning, when air conditioning defrosting, the internal unit of air conditioning will not work, only the external unit can work. This is a symptom of air conditioning defrosting.

Summary. Hello, 1.That is to say, the outdoor temperature will be relatively low in winter, and some frost will be generated on the heat exchanger of the outdoor unit, which is what we call the frost layer.

2.And in order to avoid the impact of these frost layers on the use of the air conditioner, the air conditioner itself also needs to be frosted, and then the air conditioner will be frosted. 3.

Air conditioner defrosting can improve the heat exchange effect of the air conditioner. When the air conditioner is defrosted, the internal unit of the air conditioner does not work, only the external unit can work. This is a symptom of air conditioner defrosting.

Hello, 1.That is to say, the outdoor temperature will be relatively low in winter, and the heat exchanger of the outdoor unit will be molded into some frost, which is what we call the frost layer. 2.

And in order to avoid the impact of these frost layers on the use of the air conditioner, the air conditioner itself also needs to be frosted, and then the air conditioner will be frosted. 3.Air conditioner defrosting can improve the heat exchange effect of the air conditioner.

When the air conditioner is defrosted, the internal unit of the air conditioner does not work, and only the external unit can work. This is a symptom of air conditioner defrosting.

2.Air conditioner can bury filial piety and improve the heat exchange effect of air conditioning. When the air conditioner is defrosted, the internal unit of the air conditioner does not work, and only the external unit can work. This is a symptom of air conditioner defrosting.

If the outdoor unit of the air conditioner drips, the outdoor unit of the Lupei room emits steam, or the indoor unit stops blowing hot air, these can prove that the air conditioner is defrosting. 2.If frost forms inside the heat exchanger of the indoor unit of the air conditioner during use, it may also be that the temperature of the indoor unit of the air conditioner has dropped rapidly, or the air conditioner has stopped heating.

These phenomena indicate that the air conditioner has frost. 3.After the defrosting of the air conditioner is completed, the outdoor unit of the air conditioner no longer drips, and the indoor temperature rises.

So, when it comes to air conditioner defrosting, we don't have to do anything with the air conditioner. As long as the defrosting of the air conditioner is completed, the air conditioner can work normally. It is also common to use air conditioners to defrost in daily life.

That's basically what defrosting means, thank you, I hope mine can help you, praise oh dear.

Gree air conditioner refrigeration shows that it is shut down after defrosting, 1. H1 is not a fault, it is defrosting, and it is a necessary process in the heating process. Second, the air conditioning is no problem, it is normal. This is the defrosting of the air conditioner, because the internal machine of the air conditioner heats up, the external unit becomes dissipated, when the heat reaches a certain temperature, the condenser of the external unit will be defrosted, at this time, the internal fan is shut down, the external fan is shut down, the compressor works, the four-way valve is reversed, and the external machine is heated after the reversal to melt the frost of the external unit (there will be steam and water generated), because the time of defrosting is different, so sometimes the water cannot be seen.

3. If you feel that the air conditioner is defrosted more frequently, it is recommended to clean the filter screen of the inner machine; In addition, the temperature can be adjusted appropriately higher. Hope it helps. Loss Zheng.
