Decoding error codes air conditioners popular brands

Both domestic and industrial air conditioning systems, for the most part, have self-test function. This function can work in automatic mode or in special mode if there are malfunctions with the equipment. As a rule, information with error codes can be observed on the displays located on the internal units of the split systems. Thanks to these data, the malfunctions due to which there were disturbances in the operation of the air conditioning system are precisely determined. For self-determination of the causes of problems in devices of different manufacturers, you can use the error code lists of various air conditioners, provided below by brand names.

LG

In LG air conditioning systems, a microprocessor, when detecting a malfunction, produces unit start blockingand then signals the flashing LED to indicate an error code.

If the system has detected several problems, then the failure that has the lowest sequence number is first of all induced. After that, there is a fault indication in ascending order. The table below shows the light codes for the errors of the LG air conditioners, and what each of them means.

You should know: the occurrence of similar errors can be triggered by unsatisfactory parameters of the electrical network, or accidental failure that occurred in the electronics of the unit. Therefore, do not rush to immediately contact the service, but simply de-energize the device and check the electrical voltage. It is also necessary to make sure that the correct one is selected. device operation 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.

Daikin

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

Panasonic

Error codes for Panasonic air conditioners are usually highlighted. on displaylocated on the wall (room) unit unit. You can find them out if you press the “CHECK” button on the remote control and hold it for at least 5 seconds.

Since instead of a button on the remote you can see only a hole, then you can use a paper clip to press a recessed button, if you straighten it, or a small stud.

After switching the console to the Panasonic air conditioners error checking mode, move it towards the indoor unit of the device and pressing the buttons,designed to control the timer (arrows “up” and “down”), start to sort through codes, starting from “H00” and further, in order. If the DTC matches in the memory of the wall unit and on the remote control, you will hear sound signal. To exit the test mode, press the “CHECK” button again.

Deciphering values ​​for Panasonic units:

Toshiba

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

Problem codes for Toshiba domestic air conditioning systems (Toshiba RAS-07S3KHS-EE / RAS-07S3AHS-EE, Toshiba RAS-10EKV-EE / RAS-10EAV-EE):

These values ​​are also applicable to the RAS-10SKHP-ES, RAS-13SKHP-ES, RAS-13S2AH-ES, RAS-07S2AH-ES, RAS-10S2AH-ES, RAS-07SKHP-ES and others.

Toshiba industrial conder fault codes:

Ballu

Error codes for Ballu air conditioners, as usual, are highlighted on display indoor unit evaporator. Each time the clima climatic technology is turned on, the microprocessor conducts self-diagnostics of the equipment and, in case of detection of malfunctions, displays special designations on a miniature screen.

Interpretation 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 launch 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 Gree air conditioning faults:

General Climate

Alphanumeric notation for problems that are highlighted on the remote control:

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

Some error codes of General Climate air conditioners listed 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 flashing, specialist assistance will be required.

Samsung

To start the self-diagnosis of Samsung, you must start the work of Conder in test mode. To do this, hold down the start button of the split system for 5 seconds. Error codes for Samsung air conditioners, when they are detected, are displayed on the display of the indoor unit.

Malfunctions in the split-systems Samsung:

Mitsubishi

To troubleshoot the technique from Mitsubishi need within 4 seconds. Hold on the remote control (at the same time) 2 buttons: “CHECK” and “SET”. When a problem is detected, the error codes of Mitsubishi Electric air conditioners are displayed on the display of the indoor unit or remote control.

In addition to the above errors Mitsubishi Electric, provided universal error codesrelated to different models of Mitsubishi Electric units:

• Error Е6 or ЕЕ - problems in the connection between the unit located outside and the indoor unit are detected. There is no signal from the sensor, or a short is detected;
• E5 code - 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 of Hitachi air conditioners. In Hitachi aggregates, malfunctions are determined by flashing lights.

TCL

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

Idea

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