Mobile LGMV can be downloaded, for example, in Google Play as a product LG Electronics, Inc. As a tool for maintenance, troubleshooting for LG air conditioning systems. The LGMV mobile application uses a limited resource on the smartphone and processes the data in real time. Data monitoring can be complicated or data cannot be completely saved if the smartphone performance is low.
It is recommended to use a smartphone high performance. If system resources are not enough due to other included Internet applications, in addition to observation during data monitoring, malfunctions may occur. Monitoring and Saving Functions may not work in full. And the Bluetooth connection connection can be disabled. In addition, the application may be disconnected due to a lack of resources or an unforeseen error.
The data level may increase depending on the number of external and internal blocks. The data transmission distance via Bluetooth can be reduced until disabling the data transmission depending on weather or environmental condition (electromagnetic waves or obstacle), etc. It is recommended to use the Bluetooth module for a short distance.

Works performed during diagnostics correspond to the work done at. The only difference is that during the diagnostics, all the basic parameters of the equipment are checked and recorded, and service The identified deviations from the norm are eliminated.
During the diagnosis of air conditioner, firstly, an external examination on the absence of mechanical damage is carried out. Not only cabinet, but also hydraulic and electrical parts of the equipment are examined. In addition, the reliability of fastenings of external and internal blocks is checked. As well as the quality of the clamps of all contact compounds of electrical equipment. Before turning on the equipment, you must view the condition of air filters. They should be not only clean, but without damage. After inspection, as a rule, it is turned on to "Cooling" mode. Use the control panel to test the system.
During the functional verification, the indication of the air conditioner modes is estimated, as well as the operation of the output blinds with a mechanical drive. One of the indirect indicators of the efficiency of the system is to control the temperature of dry air at the entrance and outlet of the evaporator. Using the pressure gauges, the average absorption / discharge pressure is performed (with free access to the outer block). Of course, the verification of the tightness of the connection of the internal and external blocks is obligatory. In addition, you need to make sure that there are no leaks in drainage system air conditioner.
On the nature of the malfunction, the specialist can be judged by the "behavior" of the air conditioner. For example, if the air conditioner is turned on and immediately turned off, after which the error message is displayed - most likely, the case in the sensors (fault sensors of air temperature or evaporator).
If the air conditioner turns on, it works 15-20 seconds, and then turns off - most likely, the fan motor of the internal unit is faulty (the speed of rotation is below the specified revolutions per minute).
If the air conditioner does not turn on at all and at the same time flashes (or not burn) all LEDs - most likely, there was failure pCB Control.
Simultaneous blinking of all air conditioning lamps, as a rule, only means the control board of control installations. Most likely, this is caused by non-compliance with the guests of network parameters, for example, due to a voltage jump in the network. Eliminate this fault is easy - just perform reprogramming the main control board. Since information about codes is provided only to authorized service centers, in this case it is necessary to contact our specialists.
If your air conditioner does not work, first of all, make sure that the air conditioner is securely connected to the outlet. Check the protection machine or fuse on the supply line, if necessary, restart the machine or replace the fuse. Read the user manual again and make sure that all modes are installed correctly.
Having done it yourself, you will save your money. Since in many cases you have caused by the engineer, having done what you can easily do yourself will require payment for a false challenge.
If these actions did not help, then contact the trade organization you can find the air conditioner. Or contact the air conditioner manufacturer's authorized service center. Of course, this is the best, speedy and reliable way to return the performance of your air conditioner. Information on how to contact them should give you a trade organization to sell the air conditioner. This information is available not only in the warranty card, but also on the manufacturer's website in the relevant regional section.
To facilitate the diagnosis in modern air conditioners there is a so-called test mode. Compared to the operating mode, the air conditioner is included in the cooling mode and does not respond to the testimony of sensors and air temperature. That is, in test mode, the air conditioner will function as much as it is necessary for the service engineer to explore the operation of the system blocks. After turning off the test mode, the air conditioner will return to normal operation.
SAMSUNG air conditioners also provide test mode. To enter the check mode, you must click on the internal block, the on / off button and hold it for five seconds. In this case, the temperature indicator displays the installed software settings option with the second interval, for example, 0B0000-1730F8: 0B00001730F80B (only for models with temperature indicator).
In the course of testing the operation of the air conditioner, the cooling mode is turned on with the following limitations:
- the compressor is forcibly working in cooling mode without turning on / off according to the installed internal temperature, without the thawing mode;
- the blade, the air flow guide up / down - to the rotation mode up-down;
- The inner fan rotates at high speed.
