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.

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 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 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 power to the device and check the 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.

Designations in LG Art Cool units:
Daikin
Daikins are pretty sophisticated equipment(from a technical point of view) and, in addition to the refrigeration unit, have electronic control boards, many various sensors and valves, power inverter and other components. If any component of the device fails, it is difficult to find the cause of the breakdown without a special function that allows you to diagnose the equipment. This procedure is carried out using the remote control, and the error codes of Daikin air conditioners in case of a malfunction of the unit can be seen on its display.
Daikin evaporator unit problems:
Faults in the system:
Other problems:
Panasonic
Panasonic air conditioner error codes are usually displayed on the display located on the wall-mounted (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 instead of a button on the remote control, you can use a paper clip to press the recessed button, if it is straightened, or a small carnation.
After the remote control enters the error checking mode of 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), start to cycle through the codes, starting from “H00” and further, by 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:

Decryption for devices brand Ballu:
Gree
If, when the air conditioner is turned on, the self-diagnosis system detects a malfunction in any module of the device, then its start is instantly blocked. At the same time, all error codes of Gree air conditioners can be observed either on the screen of the remote control or on the display of the indoor unit of the unit.
List of malfunctions 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(domestic) General Climate:
Some of the General Climate air conditioner error codes above allow the user to independently find the problem and fix it. In other cases, for example, if the def / fan (pre / def) indicator flashes, specialist assistance is required.
Samsung
To start self-diagnostics of Samsung equipment, you need to start the operation of the conder in test mode. To do this, hold 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 in the operation of Samsung split systems:
Mitsubishi
For troubleshooting in technology from Mitsubishi, it is necessary within 4 seconds. hold on the remote control (simultaneously) 2 buttons: “CHECK” and “SET”. When 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 generic error codes relating 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 were detected during the operation of the equipment, it is also necessary to check the electrical voltage in the network.
Hitachi
The tables below show the 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 flashes in 8 seconds means an error code).
ideas
In Idea units, all problems detected by the processor at startup are highlighted on the air conditioner display.
MDV air conditioners have a self-diagnostic system. This means that in the event of a malfunction, the air conditioner issues an error code. By the error code of the MDV air conditioner, it is quite easy to identify the problem.
