Inverter air conditioner quick maintenance method, inverter air conditioner maintenance skills

1.Fault judgment. First, set the switch of the indoor unit controller"Test run"If the air conditioner can run and operate stably, it can be considered that the control system is basically normal, and it should be important to check whether the sensors are good.

2.The air conditioner is not operating. Most of them are system failures, and if the air conditioner has a failure such as a constant speed or a protective shutdown, the sensor should be checked first.

You can use the multimeter R 100 to measure whether its resistance value changes. Although the resistance value of some sensors can change with temperature, their control characteristics are poor, which will also cause abnormal control of the inverter, and the sensor should be overhauled or replaced according to the situation.

3.Abrupt shutdown during operation. When the air conditioner is running, it sometimes shuts down suddenly, and it also shuts down automatically after a few minutes after starting the indoor fan to work, while the outdoor unit never works. This fault is mostly caused by the long-term temperature rise of the inverter module, which causes the performance to deteriorate or even breakdown, and should be replaced.

4.The amount of cooling (heat) is reduced. First of all, check whether the filter screen has too much dirt and dirt, and clean the filter screen immediately.

5.The air conditioner is noisy to run. First, adjust and tighten the compressor foot bolts or fan tightening bolts; In addition, the lack of lubricating oil in the fan bearing is also prone to noise, and should be regularly oiled; If the power supply voltage is too low, it will also cause the compressor to run unbalanced and increase the noise, so the power supply system, especially whether the power socket and plug are in good contact.

6.Repair precautions.

1) Pay attention to whether the mains voltage is normal. If the voltage is not normal at the power outlet, check whether the main power switch is in poor contact;

2) Prevent the filter capacitor from discharging and hurting people. The maximum capacity of the filter capacitor in the inverter air conditioner is 4700 F, which should be fully discharged after 10 minutes of disconnection to protect the human body from electric shock.

3) The condenser and evaporator have more dust and dirt, which will affect the refrigeration and heating effect, and should be cleaned by professional maintenance personnel.

When the air conditioner displays E1**, it is generally due to the high pressure protection of the compressor, because the current of the compressor is too large, so the compressor becomes too hot, the exhaust temperature is too high, and the module protection is activated, and then we should check the overload protector and some problems of the compressor.

The reasons for these problems are: 1. There is something obstructing the condenser, 2. The outdoor temperature is too high, higher than 43 degrees, 3. The control loop is abnormal, and 4. The pressure of the high-pressure pipe is too high.

Correct resolution of E1 failures**.

When the Gree air conditioner fails, we can analyze the cause of the failure and the location of the fault according to the corresponding meaning, if it is because of the problem caused by poor heat dissipation of the outdoor unit, it only needs to be cleaned in time. If the outdoor fan does not rotate, we only need to replace the fan and fan capacitors. If it is caused by high-voltage protection, then you need to repair the high-voltage protector, signal lines and control panels.

4.Observe the operation status of the reed head shrinking machine: the compressor of the inverter air conditioner is the core component, which is responsible for compressing the number of refrigerant sections.

You can judge the working state by observing whether the compressor is running normally and whether there are problems such as abnormal noise or vibration. If a problem is found, it is recommended to ask professional and technical personnel for repair or replacement in time.

1.Regular maintenance: Regular maintenance of the frequency conversion nucleus is the key to maintaining its good running state. You can clean and maintain it according to the requirements on the product manual, or ask a professional technician to perform regular maintenance.

2.If you encounter more complex problems, it is recommended not to disassemble or repair them yourself, so as not to cause greater damage. It is best to ask professional maintenance personnel to deal with it to ensure safe and effective mold repair.

With the continuous progress of climate change and technology, inverter air conditioners are becoming more and more common and have become one of the indispensable household appliances in modern homes. Although inverter air conditioners have become more and more reliable, after a period of use, it will also have situations where it needs state-pure maintenance. This article will introduce the methods and steps to repair inverter air conditioners.

First of all, we need to understand how inverter air conditioners work. The main component of the inverter air conditioner is the compressor, which regulates the working state of the condenser and evaporator by controlling the timing of the motor speed to achieve the required temperature and humidity. Therefore, if an inverter air conditioner fails, it is usually due to a problem with components such as circuits, compressors, sensors, or controllers.

In order to repair an inverter air conditioner, you first need to check whether it is working properly. If the air conditioner fails to start or shuts down frequently, it may be due to a faulty electrical circuit. In this case, you can check whether the wires and plugs are connected properly, or adjust whether the power supply voltage is within the specified range.

If the air conditioner still doesn't work properly, it may be due to a problem with the compressor. In this case, it is best to have it repaired or replaced by a professional technician. Usually, the sign of a compressor failure is a thermal sensor alarm, and the water pipe between the indoor unit and the outdoor unit of the plain code air conditioner will have problems such as freezing, blockage, etc.

If the inverter air conditioner starts normally but the air is not cool, or the cooling effect is not good, it may be due to a problem with the evaporator or condenser. This is where cleaning or replacement is required. Note that the filter and evaporator of the inverter air conditioner should be cleaned regularly to keep the air circulating and clean.

Before repairing the inverter air conditioner, it is recommended to check the instruction manual of the equipment and follow the safety operation procedures. If you are unsure about repairing an inverter air conditioner, it is best to seek the help of a professional technician. The correct maintenance method can not only extend the service life of the inverter air conditioner, but also ensure air quality and energy saving and environmental protection.

Inverter air conditioner repair includes the following steps:

1.Check whether the power supply and wires are connected properly to ensure that the power supply is stable.

2.Check the inside of the air conditioner for foreign objects or dust accumulation, and clean the inside of the air conditioner.

3.Check whether the electronic components of the air conditioner are normal, such as capacitors, resistors, inverters, etc., and need to be replaced if there is a fault.

4.Check whether the compressor of the air conditioner is normal, and if there is a fault, you need to replace it.

5.Check whether the condenser and evaporator of the air conditioner are normal, and if there is a fault, it needs to be replaced.

6.Check whether the refrigerant in the air conditioner is sufficient, if it is insufficient, it needs to be added.

7.Check whether the control surface of the air conditioner is normal, and if there is a fault, it needs to be replaced.

8.Test the cooling effect of the air conditioner to ensure that the air conditioner is working properly.

The above are the basic steps of inverter air conditioning maintenance, if you are not familiar with air conditioning maintenance, it is recommended to find a professional air conditioning maintenance personnel for maintenance.

Inverter air conditioning maintenance --- compressor low-pressure fault maintenance method: (1) Accept whether there is any problem with the refrigerant of the system, such as fluorine leakage, otherwise the system will not start normally. When repairing, first measure whether the system pressure is normal and whether there is oil at the pipe interface.

Secondly, an appropriate amount of refrigerant can be added, and the oily part should be leaked to avoid secondary leakage of fluorine. (2) Vertical frequency air conditioner maintenance to see if there is a problem with the low-pressure sensor. Often, the resistance value changes, and the temperature received is not accurate, so the motherboard CPU thinks that the refrigerant is insufficient, so the shutdown protection is completed.

If you jump to low-voltage protection mode when the power supply is not running, you can measure whether the low-voltage sensor is damaged first. (3) If it is a performance system failure, the system components need to be accepted one by one. Inverter air conditioner maintenance --- when the fan stops, maintenance method:

1) Check whether the inner coil temperature sensor is abnormal. Resistance can be tested. If the resistance difference is too large, you can be sure that the indoor coil temperature sensor has been damaged, as long as it is replaced in time.

2) Accept the internal fan and speed to see if there is a problem with the circuit. Uninterrupted high-frequency operation and maintenance methods of inverter air conditioning maintenance --- external unit: (1) Whether the gap between the acceptance set temperature and the actual environment is too large.

2) There may be a problem with the thermistor. You can test with a multimeter to see if there is any change in the resistance value, and if there is a problem, please replace it in time. (3) Too little refrigerant.

When the refrigerant is too small, it is difficult for the air conditioner to reach the indoor temperature requirements, the external machine will always be in a high-frequency working state, if it is too serious, the air conditioner will switch to the high temperature voltage protection mode. (4) The anti-interference performance of the motherboard is poor. Look around the cables to see if they affect the motherboard, and if so, clean them up in time.
