Famous pirates of the Caribbean, next to whom the movie Jack Sparrow is just a boy

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

In this regard, residents of Moscow are very lucky, having the opportunity to use the services of technicians from the ETekhnik service center, who identify air conditioner malfunctions right at their clients’ homes and fix them. 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 that an ordinary person knows what an eeprom error is, you can independently find out what specific malfunction we are talking about.

Common error codes for air conditioners of various brands

Self-diagnosis systems of modern equipment, with the help of which air conditioning is carried out, are designed to self-check the performance of split systems, and if a malfunction is detected, notify users by displaying error codes on the displays of internal 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 monitoring the serviceability 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 by 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 susceptible to breakdowns from time to time, which their owners are notified of by displaying codes on the displays indicating a particular 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 external and internal units, which is not established after thirty seconds from the moment the unit starts. After the indicated error is recorded, it is likely that the fan of the indoor unit will work.	The occurrence of the indicated malfunction may be due to incorrect installation of 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 records the fact that the temperature in the room is too high or, conversely, too low.	This malfunction is due to an open circuit or short circuit (short circuit) in the sensor.
Error H19	Thanks to this error, the user learns that the indoor unit motor (IMU) is jammed. This is manifested by a discrepancy between the actual speed and the value set by the processor.	This malfunction can occur for several reasons: · breakdowns of the motor itself; · failure of the indoor unit board; · malfunction of the MVB wire connectors.
Error H21	The display of this code on the air conditioner display indicates a malfunction of the float sensor drain pan of the indoor unit.	This malfunction is caused by a clogged drainage system. In such a situation, you should check the sensor logic 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 caused by a broken sensor, or a short circuit in the specified sensor.
Error H24	Thanks to this error, users will learn that sensor No. 2 of the heat exchanger temperature in the indoor unit has failed.	The reasons for the problem are the same as in the case of sensor No. 1.
Error H27	This code is evidence that the outside air temperature sensor is broken.	The problem is due to the same reasons as stated in the previous two paragraphs.
Error H28	The indicated error indicates a malfunction of sensor No. 1 of the temperature of the outdoor unit.	The failure may also be due to an open circuit or a short circuit in the sensor.
Error H30	We are talking about a failure of the compressor discharge temperature sensor.	The problem may be due to an open circuit or short circuit.
Error H35	This is an error in the operation of the drain pump.	This breakdown is usually caused by a clogged drainage system. To restore the operation of the drain pump, the resistance of the windings is usually checked its motor, the value of which should be approximately 200 Ohms.
Error F11	This code is displayed when the four-way switching valve is not operating 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, for example, those that indicate problems:

with temperature sensors in the internal 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 units under discussion should be trusted only to professionals, for example, those who work at the Moscow service center “ETekhnik”.

LG air conditioner error codes

Another very popular brand of household appliances is LG air conditioners and split systems, which is due to its significant advantages: original design, a wide variety of colors, excellent quality, a large number of different, including innovative functions, and, of course, a high degree of reliability. But breakdowns also occur with these units, and therefore their lucky owners will need information about error codes for LG air conditioners.

Error code	LED blinking order for faults	Causes problem arises	Trouble-shooting
Error 1	One flash every 3 seconds	This code indicates that one of the thermistors on the indoor unit board, which controls the temperature of the outside air and the refrigeration circuit tube of the unit, is faulty. This may be caused by an open circuit or a short circuit.	To eliminate the malfunction, first check the thermistors, and if necessary, replace the internal unit of the split system.
Error 2	Two blinks every 3 seconds	This error indicates a failure of one of the thermistors of the outdoor unit. We are talking about the outside air temperature sensor or the refrigeration circuit pipe of the unit.	If such an error is displayed, the wizard first checks for malfunctions in thermistors.
Error 3	3 flashes every 3 seconds	This error indicates that the split system is operating simultaneously 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 every 3 seconds	This error indicates that the compressor overload protection is activated.	If the error under discussion occurs, the specialist checks the compressor overload protection system for current overload, gas pressure in the system, etc.
Error 5	5 flashes every 3 seconds	This error indicates a violation in the exchange of data between the indoor and outdoor units of air conditioners with each other.	We are most likely talking about a violation of the connection between the outdoor and indoor units. In this case, the cable lines are checked for possible breaks or short circuits. To eliminate a malfunction, it is often necessary to change the interconnect cable.
Error 6	6 flashes every 3 seconds	This error indicates the existence of a problem related to the fact that one or more relays of the outdoor unit consumed a current higher than normal for a short period of time.	To eliminate the problem, the serviceability of the actuators of the outdoor unit is checked, and, in addition, there is a possibility that their controls are faulty - we are talking about the key power relays.
Error 7	7 flashes every 3 seconds	This error indicates that the outdoor unit has consumed higher than normal current for a long time.	When such an error occurs, the technician checks the refrigerant pressure in the vaporizer-condenser system, and, in addition, checks the elements of the external module for serviceability air conditioners.
Error 8	8 flashes every 3 seconds	The indicated error indicates that the fan motor is faulty, which, naturally, is manifested by a violation or lack of rotation of the fan.	If this error occurs, the engine, elements of its control circuit and terminal contacts are checked for serviceability.
Error 9	9 flashes every 3 seconds	This error indicates a malfunction of a part such as a four-way valve.	When the indicated error occurs, the specified valve is checked to ensure its serviceability.
Error 10	10 flashes every 3 seconds	This error is an indication of a malfunction of the thermistor, which monitors the temperature of the compressor housing. The problem may be due to a network break or short circuit.	After checking the serviceability of the thermistor, it is changed, if necessary.

Both domestic and industrial air conditioning systems, for the most part, have self-diagnosis function. This function can operate in automatic mode or in special mode if problems occur with the equipment. As a rule, information with error codes can be seen on the displays located on the internal units of split systems. Thanks to this data, the malfunctions that caused disruptions in the operation of the air conditioning system are accurately determined. To independently determine the causes of problems in devices from 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 any problem is detected, produces unit start blocking, after which it gives signals by blinking LEDs, which indicate the error code.

If the system has detected several problems, then the failure that has the lowest serial number is induced first. After that, faults are indicated in ascending order. The table below lists the error codes for LG air conditioners and explains what each of them means.

You should know: the occurrence of similar errors can be caused by unsatisfactory parameters of the electrical network, or an accidental failure that occurred in the electronics of the unit. Therefore, do not rush to contact service immediately, but simply turn off the power to the device and check the electrical voltage. You also need to make sure that you have selected 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 fault symbols detected by the microprocessor depends on the unit model. For LG air conditioners there may be another indication - in the form of numbers and letters.

Evaporator unit malfunctions:

Indications of defects in the capacitor unit:

Designations in LG Art Cool units:

Daikin

Daikins are quite complex equipment(from a technical point of view) and, in addition to the refrigeration unit, they have electronic control boards, many different sensors and valves, a power inverter and other components. If any component of the device fails, it is difficult to find the cause of the failure without a special function that allows you to diagnose the equipment. This procedure is carried out using the remote control, and error codes for Daikin air conditioners when the device malfunctions can be seen on its display.

Problems with the evaporator unit of Daikin equipment:

System faults:

Panasonic

Panasonic air conditioner error codes are usually displayed on display located on the wall (room) unit of the unit. They can be recognized by pressing the “CHECK” button on the remote control and holding it for at least 5 seconds.

Since only a hole is visible on the remote control instead of a button, you can use a paper clip, if it is bent, or a small nail to press the recessed button.

After the remote control enters the error checking mode for Panasonic air conditioners, point it towards the indoor unit of the device and by pressing the buttons designed to control the timer (up and down arrows), begin to cycle through the codes, starting from “H00” and further, according to in order. If the fault code matches in the memory of the wall unit and on the remote control, you will hear sound signal. To exit the check mode, press the “CHECK” button again.

Explanation of values for Panasonic units:

Toshiba

The remote control for Toshiba Ras cooling systems also has a “CHECK” button, which enables self-diagnosis of the unit.

Codes for problems in Toshiba household air conditioning systems (Toshiba RAS-07S3KHS-EE/RAS-07S3AHS-EE, Toshiba RAS-10EKV-EE / RAS-10EAV-EE):

These values also apply to devices RAS-10SKHP-ES, RAS-13SKHP-ES, RAS-13S2AH-ES, RAS-07S2AH-ES, RAS-10S2AH-ES, RAS-07SKHP-ES and others.

Fault codes for Toshiba industrial air conditioners:

Ballu

Error codes for Ballu air conditioners are displayed as usual on display indoor evaporator unit. Each time you turn on the Balu air conditioning equipment, the microprocessor conducts self-diagnosis of the equipment and, if problems are detected, displays special symbols on a miniature screen.

Explanation for Ballu brand devices:

Gree

If, when the air conditioner is turned on, the self-diagnosis system detects a malfunction in any module of the device, then its startup is instantly blocked. In this case, all error codes of Gree air conditioners can be observed either on the screen of the remote control or on the display of the internal unit of the unit.

List of faults of Gree air conditioning units:

General Climate

Alphanumeric designations of problems that are highlighted on the remote control:

Errors that are displayed on the wall unit display(internal) General Climate:

Some General Climate air conditioner error codes given above allow the user to independently find the problem and fix it. In other cases, for example, if the def/fan (pre/def) indicator is blinking, specialist assistance will be required.

Samsung

To start self-diagnosis of Samsung equipment, you need to start the condenser in test mode. To do this, hold down the split system start button for 5 seconds. Error codes for Samsung air conditioners, when detected, are displayed on the display of the unit located indoors.

Malfunctions of Samsung split systems:

Mitsubishi

To troubleshoot Mitsubishi equipment, it takes 4 seconds. hold down 2 buttons on the remote control (simultaneously): “CHECK” and “SET”. If problems are detected, error codes for Mitsubishi Electric air conditioners are displayed on the display of the indoor unit or remote control.

In addition to the above errors of the Mitsubishi Electric air conditioner, there are universal error codes related to different models of Mitsubishi Electric units:

error E6 or EE - problems were detected in the connection between the unit located outside and the indoor unit. There is no signal from the sensor, or a short circuit is detected;
code E5 - malfunctions have been detected during the operation of the equipment; it is also necessary to check the electrical voltage in the network.

Hitachi

The tables below show error codes for Hitachi air conditioners. In Hitachi units, malfunctions are determined by blinking indicators.

TCL

Error codes in TCL climate systems (air conditioners) can be deciphered using the table below (the number of LED blinks in 8 seconds indicates an error code).

Idea

In Idea units, all problems detected by the processor at startup are displayed on the air conditioner display.

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 average person may ask?

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 did not even change the name of the outdoor unit, perhaps you do not have 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 fact. 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, I confuse the wires,
And errors in the evaporator and condenser temperature sensors.

That's it, you'll agree, not much. Gree, like an air conditioner, is functionally simple, so there are not many error codes.
There are disadvantages to this simplification - these are weak varistors on the control board, insufficient smoothing

Error codes table, continued.

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

Example: country house. When owners leave their dacha, they usually turn off the power to the building using a common switch.
Those. They put it out and that’s it, they calmed down. We arrived... We turned on the lights 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, current and voltage surges occur with the load.

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 shell, usually together with the fuse of the control board of the internal unit of the split system.

There are “specialists” who use wire when burning a fuse. Is it possible to do this? It’s possible, but then, in addition to the varistors, the control board and the fan motor of the indoor unit will burn out, and... it goes all the way to the compressor windings of the outdoor unit of the air conditioner.

Fireworks at the dacha. — Expensive repairs.
