With Gree air conditioners and split systems, repairs are easier than those of the hi-fay series.

Self-diagnosis of Gree air conditioners

How can the average person ask this?

The explanation is simple Gree: codes. On Gree air conditioners and split systems, there are not many protection sensors. Those. everything is simplified.

• Internal self-diagnostics of Gree air conditioners unified and almost identical in terms of error positions of inexpensive air conditioners, for example, 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 is not enough Photoshop skills, 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,
• protection against freezing of the evaporator,
• Compressor overload protection,
• Errors in the commutation of the air conditioner during installation, I confuse the wires,
• And errors in the temperature sensors of the evaporator and condenser.

That's all, you must agree not a lot. Gree, like an air conditioner, is simple in function, so there are not many error codes.
There are disadvantages of this simplification - these are weak varistors of the control board, insufficient smoothing

Error codes table, continued.

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

Example: a country house. Leaving the dacha, the owners usually de-energize the building with a general 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 the load, current and voltage surges occur.

Varistors that smooth out voltage surges do not cope with the current load and burn out, burn well with smoke and soot, in the absence of a protective shell, as a rule, together with the fuse of the control board of the internal block of the split system.

There are "experts" who use wire when blowing a fuse. Can I do this? 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 in the country. - Expensive renovation.

Troubleshooting and breakdowns of the air conditioner, Gree: as usual, we start the codes with ...

- refrigeration circuit malfunctions,

- malfunctions of the electrical part, electrical system. power supply and air conditioner control.

E1 or EL - as a common power error.

Malfunction of the power supply or, in Russian, the voltage in the network< 210 В (сработала защита – токовая нагрузка) = Датчик темп ненормально Режим отображения = E1 Отображение уровня приоритета = 2

E1 is a fairly common mistake, I ran into it just yesterday.

The reasons for E1 are obvious - insufficient mains voltage< 210 В. При пуске компрессора происходит дополнительная просадка напряжения, токовая нагрузка max.

Baloo air conditioner error codes are required in order to identify the malfunction in a timely manner and contact the master to fix it. It should be noted that in some cases the slightest delay becomes critical, so it is better to monitor the appearance of information on the scoreboard. True, the errors of Balu air conditioners directly depend on the series. After all, the equipment differs in software, which means that it informs a person about malfunctions in different ways. This means that all possible codes should be considered depending on the series. Errors on the example of Ballu MFS2 Errors of air conditioners Balu of the MFS2 series: E1, E2, E3, E4 - an error of the Ballu air conditioner, indicating that the temperature sensor has been cut off or short-circuited; E6 shows emergency activation of the protection of the outdoor unit; E8 - an error of the Ballu air conditioner, which requires cleaning the electrostatic filter; P4 - the compressor automatically turned off, as an error appeared on the evaporator sensor, which occurs when the temperature threshold is exceeded; P5 - this error code Ballu air conditioner shows when an error appears on the condenser sensor; P6 will prompt that defrosting has started automatically. The number of codes shows how much information a person receives about the operation of his own equipment. Accordingly, he can contact specialists at the right time. Below is the most complete list of error codes and malfunctions found in this technique in general. Errors of the Balu air conditioner of the BSC, BR, BV series E1, this error code of the air conditioner is displayed when the indoor air temperature sensor does not work properly; E2 - error of the evaporator temperature sensor; E5 indicates that an error occurred in the outdoor unit, which led to the automatic activation of the protection mode; E6 - these are errors of Baloo air conditioners, showing a malfunction of the fan motor in the indoor unit. It is immediately clear that the number of codes for the last three episodes is significantly less. On the one hand, this shows how stable the models are considered. On the other hand, the user receives less information, which often leads to difficult situations and additional diagnostics of cassette air conditioner models. Air conditioner error codes are useful information that appears on the equipment screen. If you correctly recognize them, then you will be able to know exactly what kind of malfunction should be eliminated. Because of this, maintenance takes a minimum of time, which means that the owner does not have to suffer from a lack of technology. SITE `S MAP ABOUT THE SITE CONTACTS © 02stroy.ru
