Both household 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 internal blocks of split systems. Thanks to this data, the malfunctions due to which the air conditioning system malfunctions have occurred are precisely determined. To independently determine the causes of malfunctions in devices from different manufacturers, you can use the lists of error codes for various air conditioners provided below by brand names.

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

If the system detects several problems, then the failure 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 light codes for LG air conditioners, and stands for 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 in the electronics of the unit. Therefore, do not rush to immediately contact the service, but simply disconnect the device from the power supply and check the voltage. You also need to make sure that you have chosen the correct device operating mode... After these checks, you can turn on the device. 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.

Baloo air conditioner error codes are required in order to identify the malfunction in a timely manner 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 Balu air conditioners directly depend on the series. After all, the equipment differs in software, which means that it informs a person about malfunctions in different ways. This means that all possible codes should be considered depending on the series.

Errors on the example of Ballu MFS2

Errors of air conditioners Balu of the MFS2 series:

• E1, E2, E3, E4 - an error of the Ballu air conditioner, indicating that the temperature sensor has been cut off or short-circuited;
• E6 shows emergency activation of the protection of the outdoor unit;
• E8 - an error of the Ballu air conditioner, which requires cleaning the electrostatic filter;
• P4 - the compressor automatically turned off, as an error appeared on the evaporator sensor, which occurs when the temperature threshold is exceeded;
• P5 - this error code Ballu air conditioner shows when an error appears on the condenser sensor;
• P6 will prompt that defrosting has started automatically.

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

Accordingly, he can the right moment contact specialists.

Below is the most complete list of error codes and malfunctions found in this technique in general.

Errors of the Balu air conditioner of the BSC, BR, BV series

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

It is immediately clear that the number of codes for the last three episodes is significantly less. On the one hand, this shows how stable the 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 - useful information that appears on the equipment screen. If you correctly recognize them, then you will be able to know exactly what kind of malfunction should be eliminated. Because of this, maintenance takes a minimum of time, which means that the owner does not have to suffer from a lack of technology.

The comfortable life of modern people is practically unimaginable, especially in the hot season, without the presence in residential, office and industrial premises air conditioners of different types. Failure of the split-system in hot summer, and if it is used for heating the room, then in winter is a big problem that requires an immediate solution.

In this regard, the residents of Moscow are very lucky, who have the opportunity to use the services of the masters of the ETekhnik service center, who diagnose an air conditioner malfunction at their clients' homes and fix it. Although modern split systems are capable of self-diagnosis, and therefore, focusing on the error codes of air conditioners, or rather on their decoding, since it is unlikely a common person knows what an eeprom error is, you can independently find out which specific malfunction is in question.

Frequent error codes for air conditioners of various brands

Self-diagnostic systems of modern equipment, with the help of which air conditioning is carried out, are designed to self-test the performance of split systems, and if a malfunction is detected, notify users about this by highlighting error codes on the displays of indoor modules and / or remote controls.

Modern air conditioners and split systems are created on the basis of microprocessors, which leads to almost complete automation of the air conditioning control process, and, in addition, allows you to monitor the health of the equipment and how it works. Moreover, the microprocessor stops the system if it detects a malfunction, and, in addition, provides real assistance to specialists in identifying faulty components and parts, displaying error codes on the screen.
Next, we will discuss in more detail the most common error codes for air conditioning systems of popular brands.

Panasonic air conditioner error codes

Panasonic air conditioners enjoy well-deserved popularity due to their modern design, high build quality, reliability, and almost silent operation. However, they are also prone to breakdowns for a while, which they notify their owners about by highlighting codes on the displays indicating this or that malfunction.

Codes	Decoding the code and the essence of the problem	Causes of the problem
Error H11	The air conditioner error code indicates a communication failure between the outdoor and indoor units, which is not established after thirty seconds have passed from the moment the unit was started. After the indicated error is fixed, it is likely that the fan of the indoor unit will work.	The occurrence of the indicated malfunction may be due to incorrect wiring of the interconnect wires. In addition, in this way the processor can signal the failure of the electronic control boards of the external and internal units.
Error H14	With this code, the processor notifies users that the internal (room) air temperature sensor is faulty. This error fixes the fact that the room is set too high or, on the contrary, too low temperature.	This malfunction is due to its appearance to an open circuit or short circuit (SC) in the sensor.
Error H19	Thanks to this error, the user knows that the motor of the indoor unit (ICU) is stuck. This is manifested by the discrepancy between the actual speed and the value set by the processor.	The occurrence of this malfunction can be caused by several reasons: · Breakdowns of the motor itself; · Failure of the board of the indoor unit; · Malfunction of the connectors of the wires of the MVB.
Error H21	Illumination of this code on the air conditioner display indicates a malfunction of the float sensor drain pan of the indoor unit.	This malfunction is due to a blockage. drainage system... In such a situation, check the logic of the sensor and the resistance of the pump motor windings.
Error H23	The indicated error indicates a violation of the operating mode of the basic sensor (No. 1) of the temperature of the heat exchanger of the indoor unit.	The problem can be triggered by the fact that the sensor is cut off, or by a short circuit in the specified sensor.
Error H24	Thanks to this error, users will learn about the failure of the sensor No. 2 of the temperature of the heat exchanger in the indoor unit.	The causes of the problem are the same as in the case of sensor # 1.
Error H27	This code is an indication that there is a breakdown of the outdoor temperature sensor.	The problem stems from the same reasons as outlined in the previous two paragraphs.
Error H28	The indicated error indicates a malfunction of the sensor # 1 of the outdoor unit temperature.	A breakdown can also be connected with an open circuit or a short circuit in the sensor.
Error H30	This is a failure of the compressor discharge temperature sensor.	The problem may be due to an open circuit or short circuit.
Error H35	This is a mistake in work drain pump.	This breakdown is usually caused by a blockage in the drainage system. To restore work drain pump usually the resistance of the windings is checked its motor, the value of which should be approximately 200 ohms.
Error F11	This code is displayed when the four-way switching valve does not work correctly. cold / warm.	The indicated problem may be due to a malfunction of the solenoid coil of the valve in question.

In addition to those already listed above, there are error codes for Panasonic air conditioners, so, for example, those that indicate problems:

• with temperature sensors in the indoor units of air conditioners;
• with air temperature sensors;
• with evaporator temperature sensors;
• with temperature and pressure sensors;
• with radiator temperature sensors;
• with protective devices, etc.

And these are not all error codes for Panasonic air conditioners, and they are not needed by ordinary users, since the repair of the discussed units should be trusted only by professionals, for example, those who work in the Moscow service center "ETekhnik".

LG air conditioner error codes

Another very popular brand household appliances are LG air conditioners and split systems, which is due to its significant advantages: original design, wide variety colors, excellent quality, a large number of various, including innovative functions, and, of course, a high degree of reliability.

Error code	The order of flashing of the LED in case of malfunctions	Causes a problem	Trouble-shooting
Error 1	One blink after 3 seconds	This code indicates that one of the thermistors of the indoor unit board is faulty, which controls the temperature of the outdoor air and the refrigerant pipe of the unit. This could be caused by an open circuit or a short circuit.	To eliminate the malfunction, first check the thermistors, and if necessary, the internal block of the split system is changed.
Error 2	Two flashes after 3 seconds	This error indicates a failure of one of the outdoor unit thermistors. We are talking about an outside temperature sensor or a refrigeration pipe of the unit.	If such an error is displayed, the wizard first of all checks for the presence of malfunctions in thermistors.
Error 3	3 flashes after 3 seconds	This error indicates that there is a simultaneous operation of the split system for both heating and cooling.	If we talk about the causes of the malfunction, then in such cases, as a rule, there is an error when connecting the split system during its installation.
Error 4	4 flashes after 3 seconds	The indicated error indicates that the compressor overload protection is connected.	If the discussed error occurs, a specialist checks the compressor overload protection system for current overload, gas pressure in the system, etc.
Error 5	5 flashes after 3 seconds	This error indicates a violation in the exchange of data between the indoor and outdoor units of air conditioners with each other.	This is most likely a violation of the connection between the outdoor and indoor units. In this case, the cable lines are checked for the possibility of a break or a short circuit that has occurred. To troubleshoot, it is often necessary to change the interconnect cable.
Error 6	6 flashes after 3 seconds	This error indicates the existence of a problem due to the fact that one or more relays of the outdoor unit consumed current above the norm for a short period of time.	To eliminate the problem, the operability of the actuators of the outdoor unit is checked, and, in addition, there is a possibility that their control elements are faulty - these are key power relays.
Error 7	7 flashes after 3 seconds	This error indicates that the outdoor unit has been consuming more than normal current for a long time.	When such an error occurs, the master checks the refrigerant pressure in the evaporator-condenser system, and, in addition, checks the elements of the outdoor module for serviceability air conditioners.
Error 8	8 flashes after 3 seconds	The indicated error indicates that we are talking about the fact that the fan motor is faulty, which, of course, is manifested by a violation or lack of rotation of the fan.	If this error occurs, then the engine, the elements of its control circuit and the terminal contacts are checked for serviceability.
Error 9	9 flashes after 3 seconds	This error indicates a malfunction of a part such as a four-way valve.	When the indicated error occurs, then the specified valve is checked for its serviceability.
Error 10	10 flashes after 3 seconds	This error is an indication of a malfunction of the thermistor that monitors the temperature of the compressor casing. The occurrence of a problem can be associated with an open circuit or a short circuit.	After checking the health of the thermistor, if necessary, change it.
