Where can I find out what resistance the compressor windings should have and how to measure it?

Climate technology plays an important role in creating a comfortable home environment. Repair of air conditioners in case of breakdown is easy to do with your own hands, since these devices are quite simple to operate and work.

In household ventilation systems, a decrease in work efficiency is immediately felt. If some signals about the impending breakdown of home air conditioners may not be immediately noticed, then the deterioration in performance is noticeable immediately (especially in the hot season). The main types of air conditioner malfunction:

Separately, it must be said about the breakdown of floor-standing household air conditioners. Correct installation of climatic technology plays a very important role. If the installation was not carried out on a flat surface, then the drains will clog first, and then the radiator and engine will fail. The air conditioner will hum during operation and accumulate condensate, after which it will be almost impossible to repair it.

Video: how the air conditioner works

The easiest way is to clean and urgently repair the air conditioner radiator at home. Externally, the split-system radiator resembles a very fine mesh, which is located under the front panel of the device. Due to the fact that it is constantly exposed to dusty air, a large amount of debris from the outside accumulates on the mesh, which gets into your home during work. In addition, the equipment also builds up dust during downtime (winter and autumn), which also causes dust to appear on the radiator.

To be on your own clean and repair the air conditioner, need to:

Remove the panel from the device. It is attached to threaded connections, they are removed with a screwdriver or wrench (depending on the brand). In some window air conditioners (Mitsubishi, Hitachi or Daikin), the panel is also secured with hidden locks; Photo - cleaning the split system
Under it are the first air filters, through which the air flow passes both from the street and from the house. Therefore, you need to remove and soak in warm water and soap for 30 minutes. During this time, fatty deposits and dust will peel off from them, and pathogenic bacteria will also be destroyed;
A rotary fan is located under them. It is produced in the form of a roller and must be cleaned, since it is this part that helps to distill air. Its maintenance consists in wiping the blades with a damp cloth soaked in soapy water;
Further, you will find yourself in the filters through which the air flow enters from the outer compartments into the inner ones. These parts are cleaned with a roller dipped in water and soap, you can buy a special tool or use a rag wound around a long tube.

Most often, warranty repair does not imply cleaning the radiators of air conditioners, so you will have to carry out the work yourself. It is advisable to repeat the process every six months for the best effect.

Instructions on how to clean the heat exchanger of a Panasonic (Panasonic), Samsung (Samsung), VAO and others air conditioner:

It is necessary to remove the front panel and remove all parts of the external compartment. You need to get into the internal one, the heat exchanger is located exactly there;
There are several ways to clean. For example, many even professional craftsmen simply blow through the radiator with a vacuum cleaner. If you do not have this device, then you can walk over it with a soft brush;
To test its performance, dip the part in a bowl of soapy water. If bubbles come from somewhere, then the radiator needs to be soldered.

With rare use of the conditioner, or, on the contrary, after very intensive use, many owners notice that water drips from under the front panel. The problem is clogged drainage pipes... What to do:

Repair of air conditioner hoses is carried out only in the warm season, in extreme cases, at a positive temperature, otherwise it will be impractical;
If the problem was noticed after the winter season, then first you need to carefully warm up the branch with warm water and a rag - probably an ice plug has formed in the pipe;
If the malfunction was discovered in the middle of the working season, then the pipe must be blown out. For this, special compressors can be used, which are output to the internal outlet of the tube or liquid. Read the instructions first to see if cleaning solutions can be used in your conditioner.

But the most dangerous problem that requires urgent repair and can affect the operation of the air conditioning compressor or its clutch is refrigerant leakage. The main insidiousness of a malfunction is that it is very difficult to detect. Not even all professional workshops provide such a service. Leakage signs:

Noise during operation;
Decreased cooling efficiency;
Sudden changes in temperature.

Before starting the repair, you need to find the place of the leak. There are several ways to do this. The easiest is, again, using a soapy solution. It is necessary to lubricate the pipes of the refrigeration circuit with a special soap (you can also use the usual 1: 1 solution, but its effectiveness is lower), and watch where bubbles appear.

In some brands, a liquid is added to freon, which glows under ultraviolet rays. Of course, you will need to arm yourself with a UV lamp, but this is the fastest and most efficient option. It will not work to repair high and low pressure pipes on your own, moreover, if the problem is not detected in time, the repair will be more expensive than the cost of the equipment. Therefore, we recommend that you immediately contact the service center with this leak.

If you notice a malfunction in the operation of your air conditioner, or it does not turn on at all, you need to think about whether it needs repair, and you can try to do it yourself, since the warranty period has long expired.

Of course, you will not always be able to repair the air conditioner yourself.

But still, there are such breakdowns that you can fix it yourself, even if you are far from being able to repair household appliances. By doing this, you will save money in your budget.

Before carrying out repair work, you need to carry out diagnostics in order to know what is broken. The same procedure will allow you to find out if the air conditioner has broken at all.

Many modern models of air conditioners have a special display system that notifies the owner of any breakdown. And this happens in automatic mode.

Depending on the color of the indicator, the frequency of its blinking and other parameters, it is possible to determine the cause of the malfunction and ineffective operation of the device.

All instructions for determining the causes of the malfunction are described in the user manual. In case of lack of information, you can contact the service center for paid assistance.

When an air conditioner malfunctions, the light blinks a certain number of times, according to the detected error. Common standard error codes for air conditioners with specific flashing light colors are shown below.

Image - DIY ovb air conditioner repair

1 time - One of the thermistors of the indoor unit, which controls the incoming air temperature through the gas pipe, is out of order. It is worth checking the operation of the thermistors of the indoor unit of the air conditioner.

2 times - The outdoor unit thermistor is out of order, this is the temperature sensor of the incoming air or the gas pipe. To repair an air conditioner with your own hands, you need to check the performance of such thermistors.

3 times - The air conditioner works for cooling and heating the air, therefore it is so important to correctly set the operating modes of the air conditioner. Check that the cooling and heating control systems are working properly.

4 times - The compressor overload protection system is switched off. It is necessary to check the correct operation of the compressor protection against large overloads.

5 times - Errors in the exchange of information between outdoor and indoor units. Check the serviceability of the cable and the communication circuit of both units.

6 times - The power consumption of the executive devices of the external unit was briefly higher than the set rate. It is necessary to check the operability of the executive devices of the external unit and the main power transistors.

7 times - The total electrical voltage of the outdoor unit was above normal. You need to learn how to repair the air conditioner, check the refrigerant pressure in this system and the performance of the elements of the outdoor unit.

8 times - The fan motor is defective. Check the operation of the engine and the control circuit of the engine elements.9 times - Directional valve defective. Check the functionality of this valve.10 times - The thermistor, which controls the temperature of the compressor casing, does not work. Check the performance of the thermistor.If the diagnostic procedure is not so complicated and difficult, then the repair is a completely different matter. Not every breakdown can be fixed on your own. But there are also simpler ones, for example, if the air conditioner does not turn on, you must first make sure that it is connected to the power supply network, and whether the voltage is supplied to the network. For a while, you can turn it off completely, give it a "rest", and then start it up again.Similar manipulations can be performed with the remote control. That is, you can check if the batteries are dead. This happens quite often, especially in the summer. If all these manipulations have not brought any results, then, most likely, you will have to contact a service center, which not everyone wants to do, given how much it costs to repair air conditioners.If the air conditioner starts but does not work efficiently, in some cases it can be helped. Among such situations:

condensation and dripping water;

clogged air conditioner filters;

excessive draft through the device.

If a person finds that water begins to flow from the indoor unit, then the first step is to determine the cause of such a leak. Among other things, condensation can accumulate on the surface of the unit, which also applies to malfunctions.The main reason for such a breakdown is mainly a malfunction of the drainage channel. In the process of using the air conditioner at sub-zero temperatures, it may become clogged.Condensation on the indoor unitCondensation and water dripping from the unit are only the first signs of a breakdown, the results of which can be dire. That is, the condensate in the drainage channel can freeze altogether, forming a plug.As a result, due to the lack of a drainage channel, the air conditioning system may stop working altogether. If such signs were found, it is worthwhile to carry out prophylaxis that will help prevent the formation of a traffic jam.Preventive measures in this case involve heating the drainage channel to a temperature of +6 degrees Celsius. For heating, experts recommend installing a special cable during the installation of the air conditioner.If a blockage occurs, the air conditioner should never be used in cooling mode. Better to wait until the temperature rises on its own and the cork melts without assistance.Another fairly common breakdown is filter clogging. The mesh installed on the outer panel allows air to pass through itself, which does not always shine with cleanliness. Moreover, there is enough dust in the room itself.Dirt and dust particles settle on the mesh, obstructing the passage of air. Poor cooling performance can be considered the main symptom of filter clogging. Image - DIY ovb air conditioner repair

Clogging of filters is quite common, because in cities, especially with developed industry, the air quality is not always within the normal range.

Automotive exhaust, industrial gas emissions, etc. Is all that an air conditioner filter has to deal with every day. So the filters need to be cleaned and changed in accordance with the instructions.

It is worth noting that some models of air conditioners are not always friendly to neighboring electrical appliances, such as electric stoves, electric kettles, etc.

In addition to insufficient cooling, the air conditioner may create excessive draft. But unlike previous problems, eliminating the cause of the draft is a fairly simple procedure.

Often, the auto-oscillating shutter function, which is built into most modern air conditioner models, can help here. This is true, because the uniformity and intensity of cooling of certain zones will depend on the placement of the air conditioner blinds.

As for all other cases, it is better to use the services of a service center here. It is not recommended to dismantle or disassemble the air conditioner on your own, and even more so to repair the air conditioner radiator, because this can cause damage that is incompatible with further operation.

We are all happy when buying a new thing, especially new equipment. The availability of household appliances determines how comfortable we will feel in our own home. But when purchasing equipment, we do not know how long it will last. The service life does not always depend on the original characteristics of the device and on the quality of its assembly at the factory. The duration of the productive use of equipment is largely influenced by external factors during its operation, how well it is handled and looked after. The new climate regulator is a joy in the house, but in order to fully enjoy its work, you also need to know how to properly repair the air conditioner with your own hands. The services of professionals, unfortunately, are not cheap.Is it possible to repair such complex equipment as an air conditioner on your own without the presence of specialists? This question is of interest to many. Let's try to give a detailed answer to it. But first, you need to find out what types of problems are with climate systems.Here are the most common problems that arise during the operation of air conditioning equipment, and as a result of which it may be necessary to repair the air conditioner in the apartment:

Decreased production of heat or cold;

Condensation leakage due to clogged drainage;

The equipment does not turn on and does not react in any way to commands from the control panel;

The appearance of an unpleasant odor from a working device.

In the first case, it turns out that the air conditioner consumes electricity in vain, giving nothing in return. He does not cope with his main task. What can cause a decrease in device performance, and how can this be eliminated?There can be many reasons, the main ones are:

Leakage of freon, which is the main element of the system, allowing it to work. It can be caused by technological reasons, or it can arise by accident. It is necessary to check the device for leaks and refill it, if necessary.

Perhaps the main components of the heat pump parts are out of order, that is, the evaporator, compressor, fan, valves, sensors, or some of the control elements. In this case, you cannot do without replacing faulty components.

Various abnormalities in the electrical network, such as surges, dips and voltage drops. This must be taken into account when connecting the air conditioner to the home network and, if possible, exclude them, otherwise malfunctions in the operation of the device will become the norm.

But not only filters can get clogged, but also other internals of the air conditioner. They also need to be cleaned in time, otherwise such an unpleasant problem as leakage of drainage may arise. A lot of debris can settle in the drain pipe, as a result, the pipes become clogged, and liquid from the indoor unit can flow out directly onto the floor in the apartment. Agree, this is not very pleasant.Leakage is eliminated by thorough cleaning of the drainage channel from foreign particles. In winter, the cause of the leak may lie in the clogging of the tube with an ice plug. In this case, the most optimal solution would be to clean the evaporator, or to refuel the air conditioner with freon.If the equipment does not start at all and does not respond to commands given by the remote control, then, first of all, you should check the voltage in the electrical outlet. In order to measure the voltage, you must use a special device - a multimeter.If he showed that the voltage in the network is sufficient for the correct operation of the device, then the cause of the malfunction should be looked for in something else. But for an accurate diagnosis, you first need to pull out the power outlet, completely de-energizing the device. After a minute, the air conditioner is turned on again. If nothing happens, then the batteries in the remote control may need to be replaced. It's easy to do it yourself.In the course of its activity, the air conditioner passes through itself a huge amount of air, the quality of which is not always ideal. Therefore, often after some time, the device you bought begins to smell bad when it is turned on. The odor can be caused by bacteria that accumulate on the filter elements of the equipment. What to do in this case? Treatment of device filters with special antibacterial agents can help out here. It may also require additional treatment with a steam generator of the evaporator radiators.In what cases is it not worthwhile to do it yourself? If the breakdown of the air conditioner:

Not caused by one of the reasons listed above;

The methods of emergency assistance to the device presented here did not help you;

You suspect that the problem has occurred in one of the complex and important parts of the air conditioner, such as the compressor.

In this case, you should seek professional help. Do-it-yourself air conditioning compressor repair is successful in quite rare cases. There is a great risk that the system will never work at all and that it will need to be completely replaced, or some of its important and expensive parts or assemblies should be replaced.Remember that the duration and productivity of the climatic device directly depends on the timeliness and correctness of the service and maintenance work. You can find out about the procedures that need to be carried out after certain periods of the device's operation from the instructions attached to it.Almost all modern models of air conditioners have indicators that can show where there is a malfunction. This can be determined by the number of flashing lights on the indicator:

One blink - the thermistor in the indoor unit does not work;

Two flashes - the thermistor in the external unit does not work;

Three flashes - one of the systems - cooling or heating - is not working correctly;

Four flashes - the compressor overload protection system is not enabled;

Five flashes - the communication between the indoor and outdoor air conditioner unit is broken, you need to check the cable;

Six blinks - the actuators of the external unit are faulty, or the problem is in the power transistors;

Seven blinks - problems with the external unit and refrigerant pressure;

In order to minimize the risk of equipment breakdown, it is enough to carry out timely preventive maintenance of its operation approximately every month. Preventive measures in relation to the indoor unit include:

Surface cleaning by wiping with a damp cloth and detergent.

Washing the blinds from accumulated dust and dirt.

Checking the attachment.

Checking the pressure and an extraordinary refueling with freon, in the event of a shortage of it.

Checking the remote control batteries.

Checking the heat exchanger for frost.

Monitoring the air temperature at the entrance to the unit.

Cleaning filters.

Verification of operation in various modes.

2 times - The outdoor unit thermistor is out of order, it is the temperature sensor of the incoming air or the gas pipe. To repair an air conditioner with your own hands, you need to check the performance of such thermistors.

3 times - The air conditioner works for cooling and heating the air, therefore it is so important to correctly set the operating modes of the air conditioner. Check that the cooling and heating control systems are working properly.

4 times - The compressor overload protection system is turned off. It is necessary to check the correct operation of the compressor protection against large overloads.

5 times - Errors in the exchange of information between outdoor and indoor units. Check the serviceability of the cable and the communication circuit of both units.

6 times - The power consumption of the executive devices of the external unit was briefly higher than the set rate. It is necessary to check the operability of the executive devices of the external unit and the main power transistors.

7 times - The total electrical voltage of the outdoor unit was above normal. You need to learn how to repair the air conditioner, check the refrigerant pressure in this system and the performance of the elements of the outdoor unit.

8 times - Fan motor is faulty. Check the operation of the engine and the control circuit of the engine elements.9 times - Directional valve defective. Check the functionality of this valve.10 times - The thermistor, which monitors the temperature of the compressor housing, does not work. Check the performance of the thermistor.Remember that some errors can occur when there is an accidental power failure in the system. This can be due to voltage surges in the network. Therefore, before starting work, watch a video about repairing an air conditioner, turn off the compressor, and then check the voltage in the network, and then turn it on after a few minutes. The causes of breakdowns in air conditioners are different, below we will describe their main ones.One of the signs of a breakdown of the air conditioner may be the absence of a signal coming to the control panel. The first thing to do is to check the power connection of the equipment. In this case, you need to turn off the air conditioner for a while from the power source, and then turn it on again. Image - DIY ovb air conditioner repair

If this does not help, you need to contact the service center specialists. Also, the air conditioner may not work due to the disconnected machine. It is also necessary to check the operation of the batteries installed in the control panel, since in hot weather they drain faster than usual.

One of the unpleasant and frequent problems that arise during operation is often dripping water and condensation. Many owners are stumped with this problem. Still, what is the reason for this breakdown and the cost of repairing the air conditioner in this case? Constantly dripping moisture most likely indicates a clogged water drain valve. This usually happens due to the fact that the equipment operates in cooling mode at negative temperatures.

You also need to know that water dripping from the indoor unit leads to unnecessary consequences. This can be expressed in the appearance of an ice plug, which appears from the frozen condensate.

It is necessary to take the following measures to eliminate these shortcomings:

It is imperative to take preventive measures before the ice plug appears so that the cost of repairing an air conditioner does not skyrocket. This means that the drainage pipeline should be warmed up to plus 6 degrees. The best solution for effective heating is the use of a special cable during installation.
If an ice plug has already appeared, in such a situation it is worth waiting for warm weather. It is strictly forbidden to turn on the air conditioner for cooling after an ice block has formed.

Among other things, the opposite problem may also occur - an excessive draft that an air conditioner can create. But unlike repairing an air conditioner pump, drafts are much easier to deal with. Basically, you can use such a function, which is called “auto-oscillation of blinds”, which is found in almost all models of air conditioners.

Image - DIY ovb air conditioner repair

It is worth installing the blinds on the panels in a horizontal position, and the excessive draft will turn into a small pleasant breeze that evenly cools the room. This function is usually always present in the air conditioner settings, and this is always written in the instructions.

In all other cases that occur, you need to contact the specialists at the service center. You should not disassemble the air conditioner unit itself or dismantle it if you still have it under warranty.

Also, the protective mesh can become clogged with dust or debris on the outer panel of the climatic equipment, which, of course, will affect the operation of this device. One of the symptoms of a malfunction is a very low cooling of the room. When water is dripping or pouring, it may be a problem in the drainage system, and not just a consequence of clogged filters.

First, you need to prepare the tools for repairing the air conditioner, remove the external panel of the equipment and clean it, be sure to check the integrity and condition of the drainage system after that. Contaminated filters are a big problem, especially for residents of cities and megalopolises where manufacturing and industrial enterprises operate.

Another reason may be poor-quality carpet for the floor, small particles of which can clog filters, making it impossible for the air conditioner to properly perform its intended purpose. The inefficiency of the air conditioner should not be ruled out, which is associated with the close proximity of electrical appliances: kettles, stoves, toasters, etc.

Above we have listed the air conditioner malfunctions, which are the most common during its operation. If you are faced with more complex breakdowns, you need to contact the company that sold you the air conditioner if the unit is under warranty. If the warranty has expired long ago, call the service team at home. And in the next article, we'll talk about the problems associated with the operation of the car air conditioner!

Diagnostics of the air conditioner operation begins with turning it on.If after pressing the button for turning on the air conditioner nothing happens - the cooled air does not enter the cabin from the ventilation system, then the air conditioner clearly does not work.

In this case, open the hood of the car and carefully inspect all the piping of the air conditioner and its radiator. If there are oily spots on them, this may indicate a leak from the refrigerant (freon) system, which leads to an automatic shutdown of the compressor.

Leaking refrigerant is the result of engine vibration. These vibrations can cause the clamps on the transition rubber hoses to loosen, causing refrigerant to seep out. In order to determine which elements are still operational and which ones require replacement, you will have to pump refrigerant into the system. Image - DIY ovb air conditioner repair

Also, one of the reasons why the air conditioner does not work is the breakdown of the electromagnetic clutch.

If, when the air conditioner is turned on, a characteristic click is not heard in the clutch, indicating its adhesion to the drive pulley, or, conversely, a grinding sound is heard and a burning smell is felt, then this indicates a bearing failure.

In this case, the coupling must be replaced.

Cases when it becomes necessary to replace a compressor are most often associated with a negligent or incorrect installation of an air conditioner and its improper operation. Often, at service stations, when a refrigerant leak is detected, or the color of the insulation changes (darkening), they are limited to simply installing filters on the system line, refilling with refrigerant or eliminating the leak. This requires a more substantial and radical compressor repair. Image - DIY ovb air conditioner repair

The compressor must be rescued if moisture gets into the system or the tightness of the pipelines is broken. In these cases, urgent resuscitation is required, which includes flushing the entire system.

Flushing takes place in two stages and is carried out with freons R-11, R-113 or carbon tetrachloride. First, it is necessary to remove the contaminated refrigerant from the system using an evacuated canister. Then the system is flushed until the liquid flowing out of the compressor becomes clear. After this operation, the system is filled with a mixture of oil and flushing fluid in a 1: 1 ratio and is put into operation for a run for a period of 10 to 15 minutes. This mixture of oil and flushing fluid is then drained off. Repeat this operation if necessary. Image - DIY ovb air conditioner repair

After flushing the system, the compressor is evacuated again to completely get rid of the flushing liquid. Then comes the turn of refueling the car air conditioner with special oil. In this case, it is necessary to take into account the high hygroscopicity of this oil (the ability to absorb moisture from the air). To do this, the air contact of the oil should be minimized. And at the end of all these works, in order to prevent the presence of moisture in the system, the system should be purged with a gaseous refrigerant or dried nitrogen.

The air conditioning system of a new car is charged with refrigerant every two years, and after 5 or 6 years of operation - annually. Also, do not forget about the need to turn on the air conditioner in winter to ensure lubrication of all elements of the system. This will ensure long and reliable operation of the air conditioner.

Regardless of the type of air conditioner, an essential element of the system is an electromagnetic clutch that connects the air conditioner shaft to the drive pulley. There are several types of drive couplings that are lubricated with their own oil. Pay attention to this to avoid damage to the coupling.

When the car engine is running, the electromagnetic clutch is constantly rotating under the influence of the belt coming from the engine. When the system is turned on, a click is heard in the clutch, indicating that it is engaged with the compressor shaft. Image - DIY ovb air conditioner repair

The absence of this click and the presence of extraneous noise in the clutch indicate a possible malfunction.However, there is a serious problem in which the clutch appears to be functional, but at the same time does not transmit rotary motion to the compressor. For accurate diagnostics in this case, special equipment of service centers is required.

The positive point is that due to its design features, the electromagnetic clutch is a fairly reliable and durable unit. Also, purchasing a new clutch and replacing it is not a big deal.

The radiator of the air conditioner requires mandatory repair after minor mechanical damage or a minor accident, which led to a violation of the tightness of the radiator and a refrigerant leak.

In these cases, the radiator must be removed from the car for a detailed examination and a decision on the repair methods. Repair is carried out either by spraying or argon-arc welding. After completing the repair, a prerequisite is to check the radiator for leaks under a pressure of 20 atmospheres. Image - DIY ovb air conditioner repair

I also advise you to pay special attention to the cause of the leakage of the radiator. If the tightness is broken due to corrosion of the metal from which the radiator is made, then the repair of this radiator may be impractical. Since, for example, welding will only give a short-term effect. Radiators subject to corrosion must be replaced. This will save time and money in the future.

The cost of an original radiator for some car models can be quite high, which, as a result, will lead to high repair costs. Alternatively, you can consider purchasing a non-original radiator from a good European manufacturer. It is also possible to install a universal unit, which may require minor modifications to the pipes (pipes).

Timely diagnostics and repair of pipes, as well as connecting hoses exposed to high pressure from the refrigerant side, are the key to long-term and reliable operation of the air conditioning system.

Hoses and their connections in the air conditioner piping system are subject to vibrations from the engine side due to bumps and pits on the roads. Also, in some vehicle structures, the hoses leading to the compressor are in close proximity to the exhaust manifold, which can lead to their drying out, cracking and burnout due to the action of high temperatures.

Also one of the factors affecting the tightness is the aging of the rubber O-rings and gaskets. Aluminum piping can be subject to both internal and external corrosion. With the help of a visual inspection, you can determine the places of leaks and replace or repair the necessary elements: O-rings, pipes, hoses.

Timely inspection and care of the car air conditioner will give you comfort and good mood, keep you healthy and save money.
