Baloo air conditioner error codes are required in order to timely identify the malfunction 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. Because the equipment is different 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 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 are errors of Baloo air conditioners, showing a malfunction of the fan motor in the indoor unit.

It is immediately clear that the last three series have much less codes. 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 recognize them correctly, you will be able to find out exactly which 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 equipment.

Comfortable life modern people practically unimaginable, especially in the hot season, without the presence in residential, office and production premises air conditioners different types... Failure of the split system in hot summer, and if it is used for heating the room, then in winter is a big problem that requires an immediate solution.

In this regard, the residents of Moscow are very lucky, who have the opportunity to use the services of masters. service center"ETechnik", which diagnose the malfunction of the air conditioner and eliminate it right at the clients' home. Although modern split systems are capable of self-diagnosis, and therefore, focusing on the error codes of air conditioners, or rather on their decoding, since it is unlikely that an ordinary person knows what an eeprom error is, you can independently find out which specific malfunction is in question.

Frequent error codes for air conditioners of various brands

Self-diagnosis systems of modern equipment, with the help of which air conditioning is carried out, are designed to self-test the performance of split systems, and if a malfunction is detected, notify users about this by highlighting error codes on the displays of indoor modules and / or remote controls.

Modern air conditioners and split systems are created on the basis of microprocessors, which leads to almost complete automation of the air conditioning control process, and, in addition, allows you to monitor the health of the equipment and how it works. Moreover, the microprocessor stops the system if it detects a malfunction, and, in addition, provides real assistance to specialists in identifying faulty components and parts, displaying error codes on the screen.
Next, we will discuss in more detail the most common error codes for air conditioning systems of popular brands.

Panasonic air conditioner error codes

Panasonic air conditioners enjoy well-deserved popularity due to modern design, high build quality, reliability, almost silent operation. However, they are also prone to breakdowns for a while, which they notify their owners about by displaying codes indicating a particular malfunction on the displays.

Error H11	The air conditioner error code indicates a communication failure between the outdoor and indoor units, which is not established after thirty seconds have elapsed since the start of the unit. After the indicated error is fixed, it is likely that the fan of the indoor unit will work.	The occurrence of the indicated malfunction may be due to incorrect wiring of the interconnect wires. In addition, in this way the processor can signal the failure of the electronic control boards of the external and internal units.
Error H14	With this code, the processor notifies users that the internal (room) air temperature sensor is faulty. This error fixes the fact that the room is set too high or, on the contrary, too low temperature.	This malfunction is due to its appearance to an open circuit or short circuit (SC) in the sensor.
Error H19	Thanks to this error, the user knows that the motor of the indoor unit (ICU) is stuck. This is manifested by the discrepancy between the actual speed and the value set by the processor.	The occurrence of this malfunction can be caused by several reasons: · Breakdowns of the motor itself; · Failure of the board of the indoor unit; · Malfunction of the connectors of the MVB wires.
Error H21	Illumination of this code on the air conditioner display indicates a malfunction of the float sensor drain pan of the indoor unit.	This malfunction is due to a blockage. drainage system... In such a situation, check the logic of the sensor and the resistance of the pump motor windings.
Error H23	The indicated error indicates a violation of the operating mode of the basic sensor (No. 1) of the temperature of the heat exchanger of the indoor unit.	The problem can be triggered by the fact that the sensor is cut off, or by a short circuit in the specified sensor.
Error H24	Thanks to this error, users will learn about the failure of the sensor No. 2 of the temperature of the heat exchanger in the indoor unit.	The causes of the problem are the same as in the case of sensor # 1.
Error H27	This code is an indication that there is a breakdown of the outdoor temperature sensor.	The problem stems from the same reasons as outlined in the two previous paragraphs.
Error H28	The indicated error indicates a malfunction of the sensor # 1 of the outdoor unit temperature.	A breakdown can also be connected with an open circuit or a short circuit in the sensor.
Error H30	This is a failure of the compressor discharge temperature sensor.	The problem may be due to an open circuit or short circuit.
Error H35	This is an error in the drain pump.	This breakdown is usually caused by a blockage in the drainage system. To restore work drain pump usually the resistance of the windings is checked its motor, the value of which should be approximately 200 ohms.
Error F11	This code is displayed when the four-way switching valve is not working correctly. cold / warm.	The indicated problem may be due to a malfunction of the solenoid coil of the valve in question.

With Gree air conditioners and split systems, repairs are easier than hi-fay models.

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 short, 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 switching the air conditioner during installation, confusing wires,
And errors in the temperature sensors of the evaporator and condenser.

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: 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, and the air conditioner, refrigerator, or other Appliances does 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.
