Deciphering error codes and malfunctions of Ballu air conditioners. Common error codes for air conditioners Error e9 split system

Both domestic and industrial air conditioning systems, for the most part, have self-diagnosis function. This function can work in automatic mode or in a special mode if there is a problem with the equipment. As a rule, information with error codes can be observed on the displays located on the indoor units of the split systems. Thanks to this data, malfunctions due to which malfunctions in the air conditioning system have occurred are precisely determined. To independently determine the causes of problems in devices different manufacturers you can use the lists of error codes for various air conditioners, provided below by brand name.

In LG air conditioning systems, the microprocessor, when a malfunction is detected, blocking the start of the unit, after which it gives signals by flashing the LED, which report the error code.

If the system has detected several problems, then the breakdown that has the smallest sequence number is induced first. After that, there is an indication of faults in ascending order. The table below shows the error codes for LG air conditioners and explains what each of them means.

You should know: the occurrence of similar errors can be triggered by unsatisfactory parameters electrical network, or an accidental failure that occurred in the electronics of the unit. Therefore, do not rush to immediately contact the service, but simply turn off the device and check electrical voltage. It is also necessary to make sure that the correct device operating mode. After these checks, you can turn on the machine. Most often, this method helps in solving this problem, and it no longer appears.

The set of symbols for faults detected by the microprocessor depends on the model of the unit. For LG air conditioners, there may be another indication - in the form of numbers and letters.

Mobile LGMV can be downloaded, for example, from Google Play as a product of LG Electronics, Inc. as a tool for Maintenance, troubleshooting for LG air conditioning systems. Mobile app LGMV uses a limited resource on a smartphone and processes data in real time. Data monitoring may be difficult or data may not be fully saved if the performance of the smartphone is poor.

It is recommended to use a high performance smartphone. If system resources are insufficient due to other Internet applications that are enabled, data monitoring may fail in addition to monitoring. The monitoring function and saving function may not work fully. And also Bluetooth communication connection can be disabled. In addition, the application may be disabled due to a lack of resources or an unexpected error.

The communication level may increase depending on the number of outdoor and indoor units. Bluetooth transmission distance may be shortened to the point of turning off data transmission depending on the weather or conditions. environment(electromagnetic waves or obstacle), etc. It is recommended to use the Bluetooth module for a short distance.

The work performed during the diagnostics corresponds to the work performed during. The only difference is that during the diagnostics, all the main parameters of the equipment operation are checked and recorded, and during the service, the identified deviations from the norm are eliminated.

The list of works in the diagnosis of air conditioning

During the diagnosis of the air conditioner, firstly, an external examination is carried out for the absence mechanical damage. Not only hull, but also hydraulic and electrical parts of the equipment are inspected. In addition, the reliability of the fasteners of the external and internal units is checked. As well as the quality of the clamps of all contact connections of electrical equipment. Before turning on the equipment, it is necessary to check the condition of the air filters. They must be not only clean, but also without damage. After inspection, as a rule, switching to the "cooling" mode is performed. Use the remote control to test the system.

During the functional test, the indication of the air conditioner modes is evaluated, as well as the operation of the mechanically driven exit blinds. One of the indirect indicators of the efficiency of the system is the control of the temperature of dry air at the inlet and outlet of the evaporator. With the help of pressure gauges, the average suction / discharge pressure is measured (with free access to the outdoor unit). Of course, it is mandatory to check the tightness of the connection between the indoor and outdoor units. In addition, you need to make sure that there are no leaks in drainage system conditioner.

If something went wrong

The specialist can also judge the nature of the malfunction by the “behavior” of the air conditioner. For example, if the air conditioner turns on and immediately turns off, after which an error message is displayed - most likely, the matter is in the sensors (malfunction of the air temperature sensors or the evaporator).

If the air conditioner turns on, runs for 15-20 seconds, and then turns off, the indoor unit fan motor is most likely defective (rotation speed is lower than the set rpm).

If the air conditioner does not turn on at all and at the same time all the LEDs flash (or do not light up), most likely, a failure has occurred printed circuit board management.

Simultaneous flashing of all indicator lamps of the air conditioner, as a rule, means only a failure of the program settings of the control board. Most likely, this is due to the non-compliance with the GOSTs of the network parameters, for example, due to a power surge in the network. It is not difficult to eliminate this malfunction - it is enough just to reprogram 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.

Before…

If your air conditioner does not work, first of all make sure that the air conditioner is securely connected to the outlet. Check the circuit breaker or fuse on the supply line, if necessary restart the circuit breaker or replace the fuse. Read the user manual again and make sure all modes are set correctly.

Doing it yourself will save you money. Because in many cases the engineer you called, after doing what you can easily do yourself, will charge you for the false call.

If these steps do not help, then contact the sales organization that sold you the air conditioner. Or contact an authorized service center of the air conditioner manufacturer. Undoubtedly, this is the best, fastest and reliable way restore the performance of your air conditioner. The sales organization that sold the air conditioner should give you information on how to contact them. This information is available not only in the warranty card, but also on the manufacturer's website in the appropriate regional section.

Air conditioner test mode

To facilitate diagnostics, modern air conditioners have a so-called test mode. Compared to the operating mode, the air conditioner turns on in cooling mode and does not respond to sensor readings and air temperature. That is, in the test mode, the air conditioner will function as long as it is necessary for the service engineer to study the operation of the system units. After turning off the test mode, the air conditioner will return to normal operation.

IN samsung air conditioners a test mode is also provided. To enter the test mode, press the on / off button on the indoor unit and hold it for five seconds. At the same time, the temperature indicator displays the installed software settings option at a second interval, for example, 0b0000-1730F8: 0b00001730F80b (only for models with a temperature indicator).

When testing the operation of the air conditioner, the cooling mode is switched on with the following restrictions:
- The compressor is forced to run in cooling mode without turning on/off according to the set internal temperature, without defrosting mode;
- Vane, guide air flow up/down - turn up/down mode;
- The indoor fan rotates at high speed.

Error codes for Baloo air conditioners are required in order to timely identify the malfunction and contact the master to fix it. It should be noted that in some cases the slightest delay becomes critical, so it is better to monitor the appearance of information on the scoreboard.

True, the errors of Baloo air conditioners directly depend on the series. Because the hardware is different. software, which means that it informs a person about malfunctions in different ways. So, you should consider all possible codes depending on the series.

Mistakes on the example of Ballu MFS2

Errors of air conditioners Baloo series MFS2:

E1, E2, E3, E4 - Ballu air conditioner error, indicating that the temperature sensor was broken or shorted;
E6 shows the emergency activation of the protection of the outdoor unit;
E8 - Ballu air conditioner error, requiring cleaning of the electrostatic filter;
P4 - the compressor automatically turned off, as an error appeared on the evaporator sensor, which occurs when the temperature threshold is overcome;
P5 - this error code air conditioner Ballu shows when an error occurs on the condenser sensor;
P6 will prompt that the defrosting process has started automatically.

The number of codes shows how much information a person receives about the operation of his own equipment.

Accordingly, he can turn to specialists at the right time.

Below is the maximum full list codes of errors and malfunctions encountered in this technique in general.

Errors air conditioner Balu series BSC, BR, BV

E1, this air conditioner error code is displayed when the indoor air temperature sensor does not work properly;
E2 - evaporator temperature sensor error;
E5 indicates that an error has occurred in the outdoor unit, resulting in automatic start protection mode;
E6 are Baloo air conditioner errors showing a malfunction of the fan motor in the indoor unit.

It is immediately clear that the last three series have a much smaller number of codes. On the one hand, this shows how stable models are considered. On the other hand, the user receives less information, which often leads to difficult situations and additional diagnostics of cassette air conditioner models.

Air conditioner error codes - helpful information that appears on the equipment screen. If you correctly recognize them, you will be able to find out exactly which malfunction should be fixed. Because of this, maintenance takes a minimum of time, which means that the owner does not have to suffer from a lack of equipment.

With Gree air conditioners and split systems, repairs are easier than with hi-fay series models.

Self-diagnosis of Gree air conditioners

What explains this, the layman asks?

The explanation is simple Gree: codes. On Gree air conditioners and split systems, there are not many protection system sensors. Those. everything is simplified.

Internal self-diagnosis of Gree air conditioners unified and almost identical in error positions to inexpensive air conditioners, such as Pioneer, General Climate, Lessar and others.

You will laugh, but for example, the catalog of Supra air conditioners has not even changed the name of the outdoor unit, perhaps there are not enough skills in Photoshop, perhaps they did not consider it necessary.

In a word, how were Supra air conditioners certified in Russia? It's a mystery to me. Supra Catalog!! In faith. Heh...

Self-diagnosis of Gree air conditioners is, -

high pressure protection
protected from freezing of the evaporator,
Compressor overload protection,
Errors in switching the air conditioner during installation, confusing wires,
And errors of temperature sensors of the evaporator and condenser.

Everything, agree not much. Gree, like an air conditioner, is functionally simple, so there are not many error codes.
There are drawbacks to this simplification - these are weak control board varistors, insufficient smoothing

Error codes table, continued.

currents during voltage surges. A trifle, but it must be borne in mind when repairing air conditioners Gree and their analogues.

Example: country house. The owners, leaving the dacha, usually de-energize the building with a common switch.
Those. extinguished and everything, calmed down. We arrived ... They turned on the light with the same switch, but the air conditioner, refrigerator, or other household appliances did not work. Why? The answer is simple.

When the power is turned on with a load, current and voltage surges occur.

Varistors that smooth out voltage surges cannot cope with the current load and burn out, burn well with smoke and soot, in the absence of a protective sheath, as a rule, together with the fuse of the control board of the indoor unit of the split system.

There are "specialists" who use wire when burning a fuse. Can you do that? It is possible, but then, in addition to the varistors, the control board, the fan motor of the indoor unit will also burn out, and ... it rushed up to the compressor windings of the outdoor unit of the air conditioner.

Fireworks at the cottage. - Expensive repairs.

Troubleshooting and breakdowns of the air conditioner, Gree: codes, as usual, we start with ...

- refrigeration circuit malfunctions,

- malfunctions of the electrical part, system e-mail. power supply and air conditioning control.
