Error reporting principle
To improve the reliability of the device and prevent serious damage, Samsung air conditioners are equipped with a self-diagnosis system that continuously checks several parameters of the device.
If at least one of the specified parameters is out of the norm, the device reports this in two ways:
- On the display of the indoor unit, a combination of the letter E and three numbers, for example, E101;
- On the LED board of the outdoor unit, by glowing yellow, green and red diodes in various combinations.
The indoor units of some models of air conditioners are not equipped with a display. They report their problems in the same way as outdoor units, by flashing buttons of different colors.
The display of the indoor unit of the air conditioner in normal mode shows the air temperature, and in case of a malfunction it displays an error code
Below we will talk about the codes displayed by Samsung air conditioners in the event of a malfunction on the display or indicator board.Knowing the decoding of these alphanumeric combinations will allow you to understand what problems have arisen in the split system.
How to remove the air conditioner so that freon does not leak
During a problem, freon flows out of the device.
When buying a new split system, the required amount of freon is located in the sections of the outdoor unit. Twisted service valves in the outdoor unit keep the gas inside its elements. There is normal air in the indoor unit. During the installation period, these 2 blocks are hermetically connected by tubes, only after this action the valves open and freon acts on the indoor unit. A closed circuit is formed, according to which freon circulates throughout the system.
If freon is to be conserved, then "pumping" it back to the outdoor unit is considered the only option. All that needs to be done is to turn on the taps when the freon is in the outdoor unit.
Procedure:
- We unscrew the taps and attach pressure gauges to them. This action must be performed as carefully as possible, during the connection of pressure gauges, freon is released under pressure. To avoid burns, gloves must be used.
- For this method you will need a hex wrench. With it, you need to close the tap of a thin tube. You need to tighten the valve clockwise, making efforts, twist it until it stops. At this point, the pressure gauge will drop. After 15-20 seconds, when the pressure level drops to zero, you need to turn on the tap of an already thick tube. Immediately after all actions, the device turns off.
This method is best used only in the most extreme cases (during the cold outside, when the unit cannot be turned on). It is necessary to tighten the two taps of the outdoor unit (the air conditioner is inoperative). So it will be possible to save not all freon, but more than 50%.
freon conservation
Using the above methods, you can fix minor problems in the operation of the air conditioner yourself, while saving your money on calling a specialist. More serious breakdowns in this type of equipment are extremely rare. If you regularly carry out preventive maintenance of the device, the likelihood of a breakdown is significantly reduced.
Troubleshooting Methods
Despite different error codes in different models of General Climate air conditioners, in fact, all failures and breakdowns in them are of the same type.
Consider what the owner of the equipment should do in the event of an error:
- Fan stop. If the fan fails to start for more than 1 minute, you should check the connection of the fan motor, as well as its serviceability. If a part breaks, it must be replaced. The air conditioner fan can also malfunction if there are problems with other components. For such diagnostics, it is recommended to invite an experienced master from a specialized service.
- Problems with temperature sensors. If the self-diagnostic system gives an error of any sensor, it is necessary to check the condition of the part, its integrity and correct connection. For such a check, the owner of the air conditioner will need a multimeter. If the sensor is out of order, you need to replace it.
- EEPROM failure. Sometimes you can get rid of the EEPROM error with a simple reboot of the air conditioner. To do this, turn off the power of the device for a few minutes, then turn it on again.If the reboot did not help, the reason is problems with the electronic board. For such repairs, it is also recommended to invite a certified master repairer.
- The compressor does not start. Typically, compressor problems begin after its filter becomes clogged with dust and debris. The reason for the failure of the part may be overheating, damage to the winding or cable. The owner of the equipment can clean the filter of the device on his own, but for more complex manipulations, an experienced locksmith will be needed.
- Repeated application of high voltage. With such an error, you should first turn off the air conditioner from the power supply. The error will be automatically removed after regulation of the power supply to the device.
- Communication failure between system units. Lack of communication leads to blocking the operation of the split system. The owner of the air conditioner can independently check the connection of the interconnect cable and its integrity. If everything is in order with the cable, then the matter is in the electronic boards of the units, and you need to contact the master.
It should be noted that failures and malfunctions in the operation of air conditioners will occur much less frequently with regular preventive inspection of household appliances.
Regular and timely cleaning of equipment and replacement of worn parts will ensure uninterrupted operation of air conditioners and split systems for a sufficiently long period.
Experienced masters of authorized service centers will qualitatively and in a short time put in order a failed air conditioner or split system
To restore the operability of GC air conditioners and carry out preventive maintenance, locksmiths for the repair of climate equipment are advised to seek help from service centers accredited by the manufacturer, in which masters with the appropriate approval work.
Causes of breakdowns of Haier air conditioners
Hyer air conditioners are not afraid of intensive operational loads and operate around the clock without failures. Efficiently cool/heat residential, work and office premises.
About 92% of problems occur as a result of improper operation of devices and voltage drops in the network. By the way, so that not only the air conditioner, but also other equipment does not suffer due to voltage drops, you can install a stabilizer.
Identified damage must be repaired as soon as possible. Operating a faulty appliance exacerbates the problem and often results in damage to dependent or adjacent parts, and then the cost of repairs increases significantly.
Some private craftsmen rely on the incompetence of the client, try to impose unnecessary services, repair working elements, etc. A person who understands error codes will immediately notice this and stop attempts to deceive
To avoid most breakdowns, it is necessary to properly connect the unit and operate it in strict accordance with the manufacturer's recommendations. Then Haier will last a long time and will not cause any problems.
More rare malfunctions
Among these stand out: loss of communication between the units, "glitches" of the display panel, failure of one of the fans, failure of the control board or inverter module.
Each such malfunction is also solved.But, they are extremely rare, especially with proper use of climate equipment. If maintenance is carried out regularly, then breakdowns can be avoided for a very long time.
Timely maintenance of the indoor and outdoor units greatly reduces the risk of malfunctions. Serviceable equipment allows you to enjoy a comfortable indoor temperature for a long time
The average service life of climate control equipment without breakdowns is 7 years. And competent care of the equipment allows you to extend this time up to 15 years.
Features of the air conditioner
The technical characteristics of any climatic equipment indicated in the passport correspond to the values obtained under certain test conditions. Therefore, the air conditioner will not produce laboratory power in any weather. So, when the temperature outside the window is +50 OC, and the coil of the outdoor unit produces +90 OC, then in this case the effect of the equipment will be 2 times less if it is used in mid-latitudes at +10 OC. The same happens when using the cooling mode.
Important! The lower the outside air temperature, the more difficult it is to transfer heat into the room. Manufacturers create air conditioners, the normal operation of which provides for the absence of sub-zero temperatures on the evaporator
For this reason, condensation of a humid environment occurs. However, the water does not turn into frost. This principle of operation of the devices underlies the dehumidification option. Therefore, it is necessary to turn on the devices in turn either for heating or for cooling the air in the room. During the operating cycle of the equipment, the air temperature does not change. At the same time, the humidity of the air decreases.Ignorance of such a nuance leads to the need for communication in an air conditioner repair organization.

The device does not turn on
These are the most basic malfunctions of air conditioners, and every owner has encountered them at least once. Regardless of the brand, model, country of origin, the reasons here will be the same. This problem lies in the electrical part and lies in the fact that the device is simply not connected to the power supply, the control board is faulty, or there is no communication between the indoor and outdoor units. Also, a common reason is the failure of the remote control or the receiving module of the device. There is another error. Due to certain circumstances, the device could go into protection mode and give an error when turned on. Finally, the device does not turn on due to the banal wear of some parts. In some cases, the split system does not work or incorrectly executes the owner's commands due to incorrect switching in the signal and power wires connecting the blocks.
