Errors of Beko air conditioners: fault codes and instructions on how to fix them

Beko air conditioners are equipped with an innovative self-diagnosis system. According to its results, the control device, when a malfunction is detected, blocks the operation, simultaneously reporting its cause. Defects in operation are reported by the equipment by flashing LEDs, which are lit in a certain sequence, showing the number of the detected malfunction.

Determining the error of the Beko air conditioner can be dealt with without involving a technician from the service department. To do this, you just need to know how the information stored in the program by the manufacturer is decoded. It should also be remembered that the system displays a DTC with a higher priority.

What is the cause of the breakdown of the Beko air conditioner?

Beko air conditioners can be found in offices, apartments and cottages. These are affordable and high-quality split systems or floor-standing mobile units. Air conditioners of this brand, thanks to their practicality, functionality and reliability, work properly without breakdowns in the most difficult conditions.

However, over time, especially with strenuous use, the Beko air conditioner may fail. This can manifest itself not only by turning off the device and the appearance of an error code on the display, but also corny: the unit will begin to flow, the cooling flow will weaken, and ice will appear.

The main causes of breakdowns:

• wrong unprofessional installation of a split systemconducted by yourself or by incompetent craftsmen;
• non-compliance with the requirements for the operation of the unit;
• ignoring scheduled maintenance;
• normal wear of parts after prolonged use.

After repairing the equipment, it is imperative to study the instructions for routine maintenance of the air conditioner.

When does the Beko air conditioner turn off?

The equipment will shut down on its own if:

1. The compressor does not re-start for 3 minutes.
2. If the temperature on top of the compressor exceeds 115 degrees. Normal operating temperature should not exceed 100 degrees.
3. If the voltage in the network drops below 175 or rises above 260 volts.
4. If the inverter overheats due to high current or higher voltage being applied to it.
5. If the wires are open anywhere.
6. If the fan works more intensively than the norm or vice versa weaker (norm 300 - 400 rpm).
7. If the system does not receive zero crossing messages for 4 minutes.

After that, the self-diagnosis system begins to search for defects and malfunctions and, having found them, displays the desired error code on the display.

The above tables can be used to determine the cause of the breakdown. air conditioning and split systems. In almost all cases, the climate system turns itself off.

You need to start diagnosing an air conditioner with an analysis of the most common breakdowns.

Malfunctions of Beko air conditioners

Let's look at what kind of malfunctions of the Beko air conditioner are most often faced by owners, and we will scrupulously analyze how you can fix it.

If the air conditioner does not cool

There are several reasons why the air conditioner stops cooling. In our list, they are listed from more likely to less likely.

To identify the cause of the breakdown, you need to test each cause, starting with the first:

1. If the air filter is clogged, air cannot circulate through the air conditioner. This reduces its cooling capacity. A dirty filter can freeze the evaporator coils. In this situation, the filter must be rinsed or replaced with a new one.
2. If the condenser coils are dirty, they will not be able to dissipate heat as the refrigerant passes through them. As debris accumulates on the coils, the air conditioner will work longer and harder to generate cold. Eventually it will run continuously. The air conditioner coils can be cleaned.
3. Rarely is this situation caused by compressor malfunction. First you need to check the compressor condenser and the overload fuse. If, nevertheless, a malfunction is found in the compressor, you will have to call the wizard.
4. The cause of the problem may lie in the thermostat. The thermostat controls the temperature, when the air temperature rises, the thermostat turns on the fan and the compressor. If it is defective, it will not be able to cool down. To check the thermostat, turn on the cooling mode and use a multimeter to check for continuity. If it is violated during the operation of the air conditioner for cooling, you will have to change the thermostat.
5. All systems can operate normally, and the cause of the problem may lie in a thermistor - a temperature sensor on the control board. If the air temperature rises, the resistance value across the thermistor decreases. The serviceability of the sensor is checked with a multimeter. If its resistance does not change with temperature changes, you will have to replace the thermistor.
6. A breakdown of the control board can always be the cause of the error code.

Some parts can be repaired. With some breakdowns, nodes and components due to which split system does not cool well, cannot be restored and will have to be replaced.

How to set the climatic technology for cooling is described in detail in our recommended article.

Fan does not work

If the fan stops working, check it for the following failures, starting with the most common:

1. The fan motor is of a 2-shaft design. Such an electric motor has bearings that wear out first. To determine if this is the case, rotate the shaft. This is the most costly failure, since if the shaft does not rotate, the fan motor will have to be replaced.
2. If the blades are turned by hand and they will not rotate freely, this also means that the motor bearings are worn out. If the blades are spinning, check the power input. If there is power, but the motor still does not work, you will have to change it.
3. If a defect occurs in the relay board, then voltage will not be supplied to the motor. The relay board is replaceable and inexpensive.
4. The temperature control thermostat may have burned out contacts. To check, you need to use a multimeter to check its continuity.
5. A defective thermostat can prevent the fan from working. To check, set the air conditioner to cooling mode and check the thermostat for wiring continuity with a multimeter. If the wire is found to be damaged, it must be replaced, the loose contacts must be restored. If it’s not about them, you’ll have to change the thermostat.

All errors can be generated by a damaged control board. Naturally, in this case there must be a replacement.

Also, the reason for stopping the fan may lie in a malfunction of the thermistor, capacitor, rotary switch. If the cause of the breakdown is in the fan motor, it will have to be replaced. Worn out or burnt out fan motors cannot be repaired.

Compressor does not work

If the compressor stops working, check:

1. Electrical contacts of the temperature control thermostat that may burn out. In this case, the thermostat will turn on the fan motor, but not the compressor.
2. The temperature control board can cut off the current to the compressor. The board can only be replaced.
3. The thermostat monitors the temperature and when it rises above normal, the thermostat activates a switch to supply current to the compressor and fan.
4. The fuse may blow over time. You can check if this is the reason using a multimeter.
5. Very rarely, but the compressor itself fails. First, you need to carefully check the health of the fuse and capacitor. The compressor can only be replaced by a workshop.

Even more rare causes of compressor inoperability are problems with the thermistor, breakdown of the relay board, defect in the main control board. The capacitor may burn out.

If the equipment was installed unevenly, the drains will clog first, and then the engine and radiator will break.

Why is the air conditioner making a lot of noise?

The split system can operate noisily without any error being displayed. In this situation, it is important to react in time and find the causes of the noise. Otherwise, the breakdown may worsen and lead to the failure of the climatic technology.

What can be the reasons for noisy work:

1. Compressor wear. It should be noted that even a noisy compressor can continue to operate for years.
2. In the bearings of the fan motor, grease can coke over several years of operation.
3. The fan blade may become damaged or deformed during long-term operation and begin to touch the fan housing. It will have to be replaced.
4. The fan wheel must be stable. If it is loosened, it will have to be changed.

A noisy air conditioner, of course, creates certain inconveniences during operation, but this does not mean that parts need to be changed immediately. First you need to find out the cause of the noise, it may not be so serious.

Water leaks from the indoor unit or floor-standing unit

If a puddle collects under the indoor unit, there may be several reasons:

1. If from a monoblock unit water flows out onto the floor, which means that it is not aligned during installation and falls forward. The floor unit should be positioned so that it has a slight slope of 1-2 degrees.
2. Drainage is clogged: you need to clean or blow out the clog.
3. The drain piping was installed incorrectly. Everything should be fixed.
4. Breakdown of the pump.

Regular cleaning of the drain line is specified in the instructions for use.

After the correct installation of the split system, nothing should drip from anywhere, if this is not a feature of the drainage system.

Anti-freeze heat exchanger

A freezing heat exchanger is a fairly common problem that most often occurs due to the lack of regular cleaning or replacement of the air filter. If it is clogged, the air flow through the evaporator coils is reduced.

The air conditioner should be maintained regularly in accordance with the requirements of the accompanying instructions.

Caring for the Beko air conditioner

So, as you can see, many problems in the operation of the air conditioner arise due to untimely cleaning. Wherever the air conditioner is installed, urban or rural dust, which is not even visible to the eye, will quickly clog the pores of the filters, and the operation of the air conditioner will be disrupted.

How do you clean your air conditioner to extend its life?

Or when signs appear that indicate a clogged equipment: noise or odor during operation, water leaks, icing of the evaporator coils.

For cleaning you need:

• open the cover of the outdoor unit;
• pull out the dirty filter;
• rinse the filter and dry naturally;
• turn on fan mode;
• spray all air conditioner cleaner in the work area;
• treat the filter in the same way;
• wipe dusty blinds with a napkin or rinse under running water;
• install the filter in place;
• close the lid.

For split-system maintenance you can call a foreman from a service workshop accredited by the manufacturer to carry out all types of work with his air conditioners. He will do everything: from installation to trivial cleaning. But it is better to read the manual and carry out some of the work yourself, if you do not want to spend too much money on the maintenance of HVAC equipment.
