Air Conditioner Mistakes

All split-systems equipped with devices for self-diagnostics in case of malfunction give out the error code. Not always for repair of climatic equipment is necessary to interfere a craftsman. Many mistakes of wall-mounted conditioners can be fixed individually. For this purpose it is necessary just to get acquainted and to know standard malfunctions and how to correct them. We are going to discuss it in this article.

Malfunctions of domestic split systems are of very different nature. Having in their construction complicated mechanisms by their design, these devices need a special attention from the side of an owner. And if the equipment is not serviced in time, the split malfunctions will appear after a while. Malfunctions of such equipment can be numerous, but here only main, which in general can be characterized according to the following features will be pointed out:

  • Wrong choice of split system. In a case if power consumption is calculated incorrectly for the room, the compressor simply will not be able to create the temperature regime. At the same time it will be constantly in operation, overheat and, accordingly, will soon be out of order.
  • Improper installation of the equipment. The installation of climatic equipment demands the classified approach and if some requirements are violated the conditioner will work incorrectly. For example, if the height difference between the outdoor and indoor units is too big, the compressor will not be able to pump freon at the required pressure. And also if the draining pipe is not properly sloped, the condensate will not be removed as it should be.
  • Filters pollution. As a result of clogged filter elements cooling, heating and other modes will be disturbed, as well as frosting of tubes and condensate flowing on the floor may occur.
  • Refrigerant leakage from the main line. It should be noted here that loss of Freon from the system is inevitable due to evaporation and small leaks. That is why once a year it is necessary to call in specialists (if they do not have it in their schedule) to charge the system. If this procedure is not done, because of low volume of freon in the line will be low pressure. And as a consequence, tubes and the heat exchanger itself will frost up and finally the compressor will break down. But if even oil leakage or frost appeared on connections before time, it’s necessary to call specialists from service center immediately.
  • Air conditioner functioning at negative temperatures. As a rule, on the most models the manufacturer allows the operation of split-system up to.5 ˚С. At lower temperatures it is prohibited to start conditioners without an additional winter set.
  • Illiterate setting of operation modes of a conditioner. In order to regulate the processes correctly, it is necessary to read the instructions carefully.
  • Dirty exchanger. On the condenser of outdoor unit and evaporator of indoor module sometimes creates a layer of dirt, dust, small particles, which reduce the cooling capacity of the air conditioner.
  • And also it can be a weak voltage in a network. If there is not enough voltage on the line, the air conditioner will not develop enough power and will frequently shut down. At such malfunction of split system it is necessary to switch on the device through the regulator.

Classification of AC error codes

Fault codes of air conditioners are classified according to the conventional system of combining symbols and consist of 2-3 or more signs. They can be only figures or Latin letters, and also a combination of letters and 1-2 figures.

According to the letters it is possible to determine the place where the malfunction has occurred, and according to the number or number of blinks of the diode it is possible to determine what kind of a malfunction has occurred.

Classification of error codes:

An owner does not need to memorize all symbols and error codes of air conditioners, the more so that they are different for each brand. It is enough to pay attention to the problem in time and disconnect the unit from the network until the causes of malfunction are detected.

The air conditioner instruction manual publishes information about the codes, which will allow the owner to determine the type and difficulty of the breakdown. If the problem cannot be solved by yourself, you will have to call a service center.

Symbolic AC error codes

Symbol codes are represented as several characters, for example “”. It is not the character itself which is causing the error, but the number of characters. As a rule, symbolic error codes are displayed on the control panel.

Two-character error codes of air conditioner

Two-digit error codes use Latin letters and numbers. The first part of the code, displayed in letters, is responsible for the structural components of the split-system.

Explanation of symbols (briefly):

  • “A” and “B” are internal unit faults;
  • “E”, “H”, “F”, “J”, “L”, “P”. problems occurred in the outdoor unit;
  • “U” and “M”. these codes signal problems with the system.

The second error code is represented by digits in a sequence from 0 to 9. To determine the precise cause of the problem it is advised to study the user manual supplied with your appliance.

Three-digit air conditioner error codes

Three-digit error codes use letters and numbers, most often a combination of one alphabetic character and two numbers. There is a detailed deciphering in the enclosed manual.

Error codes

All air conditioners equipped with self-diagnosis and fault detection system generate an error code when a malfunction occurs. In turn, some “repairers” have only one goal. to earn as much money as possible on your trouble. In this regard, I recommend everyone to keep this material, from which you will learn how to identify the problem with the error code. If you know the cause of the problem, believe me, you can save a lot of money and maybe even fix it yourself.

Deciphering of error codes of Haier air conditioner

Haer air conditioners are equipped with self-diagnosis system and in case of malfunction they display the following codes. The most common faults are as follows:

  • E0. problems with condensate drainage in the system;
  • E1. pressure increase in the compressor;
  • E2. The heat exchanger of the indoor unit is icing up;
  • E3. compressor pressure too low;
  • E4. compressor overheating;
  • E5. Complete compressor shutdown due to overloading;
  • E6. no connection between outdoor and indoor units;
  • E7. room module does not respond to commands from the control panel;
  • E8. indoor unit motor is overloaded.

Also, fault codes with the letter F may illuminate on the Haer air conditioner display:

  • F0. failure of room sensor;
  • F1 and F2. disconnection of indoor and outdoor unit heat exchanger sensors respectively;
  • F3. outdoor temperature sensor failure;
  • F4. disabling the thermosensor on the air supply;
  • FF. power outages.

If the Haer air conditioner blinks 6 times when the error occurs, it may indicate an F11 malfunction. It appears when the voltage in the network does not meet the standard values.

What does FE error mean on Haier air conditioner

Users of Haer air conditioners often encounter the error FE. According to the information from the manufacturer, this malfunction is deciphered as Freon Error, or Freon leak.

If there is a lack of refrigerant, the split system may be in working order, but it constantly restarts. In addition, the unit is usually not able to perform its direct functions and instead of cooling air only moves it around the room in the fan mode.

Preventive measures

Correct preventive measures can help to prevent E 6 code in the split system. When using air conditioning equipment is necessary:

  • Vacuuming and washing of the filters of the indoor unit once a month, and better every two weeks;
  • Twice a year, in spring and fall, disassemble the room module and remove contaminants from the fan and radiator;
  • Regularly drain any residual condensate from the drain pan and clean the entire drainage system with disinfectants;
  • at least once a year, clean the front module yourself or call in professionals for this purpose, especially if the unit is located at the fifth floor level or below.

It is recommended once in 2-3 years to call in service for refilling of splitsystem with freon. Over time, it is inevitable that the refrigerant will evaporate, even if the unit is in full working order. Freon escapes at an accelerated rate if inter-unit tubing connections are loosened. When losses reach 20-30% of the total, the lack of refrigerant begins to have a noticeable effect on system operation and can cause E 6 failure.
