What to do if the split system flows into the room: common breakdowns and how to fix them

The main types of faults

Consider the main malfunctions of air conditioners and how to eliminate them. Let's make a reservation right away: if your air conditioner has broken down, it is strongly not recommended to troubleshoot on your own.

Poor room cooling

This malfunction may occur due to one of the following reasons:

• too weak power;
• internal breakdown.

It is quite possible that the power of your air conditioner is not enough to maintain the set temperature in the apartment. This may be caused by a sudden change in the climate in which the device is operated. The average temperature range of the device is from -7 to +40 degrees.

If the breakdown is not related to a change in temperature, then an internal malfunction of the device has occurred. Determining the cause on your own is quite problematic, therefore, at the first sign of a malfunction, it is recommended to carry out maintenance.

Failure in work compressor can become the main reason for such malfunctions of split systems. Repairing a breakdown is a job for a qualified specialist.

Short machine cycle

There are situations when, after turning on the device, it stops working after 15-20 minutes of continuous operation. There can be many reasons for this situation:

• failure in the settings;
• the control board is broken;
• failure of the thermostat;
• radiator contamination.

An external radiator, especially in summer, is often exposed to dust, fluff, dirt, etc. Clogging, it provokes overheating of the entire system, which leads to a stop of the device. The solution to this problem is to flush the radiator with a strong pressure of water.

When charging the system with freon, a situation may arise when the balance of the refrigerant is disturbed. By measuring the operating pressure in the compressor, you can determine how much the air conditioner is overloaded with freon.If the system is overloaded with refrigerant, it is necessary to drain the excess liquid.

Condensation dripping from the indoor unit

Dripping condensation from the indoor unit may be a signal that your equipment is malfunctioning. A clogged drain pipe could be the likely cause. In order to clean it, you must perform the following steps:

• turn off the air conditioner and wait 10 minutes;
• disconnect the plastic drain tube;
• clean and dry it;
• return to original position.

A clogged drain pipe is the cause of 90% of the cases in which condensate drips from the indoor unit. You can easily carry out this cleaning procedure without the help of a qualified craftsman.

Automatic diagnostics

Factory defects, poor installation and improper operation are the main reason that the internal parts of the air conditioner fail prematurely. Almost nothing can be done with a factory defect, in the other two cases there is a chance to improve.

The inscriptions on the display and the blinking of the lights will help you find out in time that certain problems have appeared.

in the air conditioner, they usually talk about breakdowns of the following nature:

• Broken thermistor, due to which there is no additional temperature control.
• Throttle valve problems.
• Problems inside the fan.
• Power surges at the outdoor unit.
• Exceeded parameters related to energy consumption.
• Cable or circuit problems due to communication.
• Lack of overvoltage protection.
• Work goes both on heat and on cold.
• Malfunction in the thermistor of the outdoor part.
• Faulty internal thermistor.

The instructions give a precise definition for those who are interested in deciphering the emerging codes and designations. This allows you to quickly determine what exactly happened.

But not every code has a decryption for users. Most of the information is handled by wizards related to a particular service center.

Compressor and clutch problems

If the radiator on the outdoor unit is clogged with dirt, this part of the structure may overheat. Heat dissipation becomes more difficult, the load on the device increases. A separate check requires the level of pressure in the lines. Excess refrigerant must be bled off if the indicator is above normal.

They never exclude the possibility that the fan at the external unit has become faulty. A blockage in the capillary tubes is another common reason why malfunctions appear in the future. Replacing one of the tubes often solves the problem.

There are other signs that speak specifically about breakdowns in this part:

1. Compressor failure to start when .
2. The presence of oil leaks on the compressor.
3. The creak of the compressor drive belt.
4. Extraneous noises.
5. Decreased performance.

Complete compressor replacement and repair are complex operations, so it is recommended to contact specialists immediately.

But noise can tell both about problems in the compressor and about malfunctions in the drive. The pulley bearing is very likely to be the source if the noise is heard even when the appliance is turned off.

If the compressor fails to start, they also look at several details of the mechanism:

• Coupling.
• Relay.
• Fuse.

A blown fuse is the easiest to deal with; in case of breakdowns, it is simply replaced with a new one.The electromagnetic clutch is studied next if the previous steps did not give any result.

As for the compressor itself, there are several reasons for its breakdowns:

1. Reduced coolant level.
2. System clogging.
3. Complete blockage.

Repair and replacement of a compressor is a rather expensive undertaking, therefore it is recommended to treat the part with care as much as possible during operation.

When you turn on and instantly turn off the device, the reason is more likely to lie in the sensors - evaporation or temperature. Data from temperature sensors is associated with the operation of the control board. If the system is faulty, no information is available. And the device considers that the current mode of operation does not need an adjustment for this indicator.

Compressor overheating and shutdown are often due to fan failure. This usually happens if the rotation speed of the device is less than certain specified parameters.

Dirt and dust can also appear in some other parts:

• Dryer filter.
• Outdoor Radiator.
• capillary tubes.

In such situations, the compressor stops turning on and working normally.

When to contact the service center

As you can see from the above, some of the problems that caused the leak can be fixed on your own. However, it is necessary to soberly evaluate your technical skills and knowledge in the field of climate systems. If there is no self-confidence, then when an air conditioner leak is detected, it is recommended to entrust its diagnosis and repair to specially trained service employees. It should be borne in mind that most specialists may charge an additional fee for obvious traces of unsuccessful attempts to repair the unit themselves.

It must be remembered that most major manufacturers of climate control equipment have their own official service centers in major cities of the country. Representatives of such companies, like LG, Electrolux, Midea, Daikin, are always ready to provide their specialists for warranty repairs and periodic maintenance of their equipment.

And if the external unit on the air conditioner flows, what is the reason

Sometimes air conditioner owners notice that water is leaking from the outdoor unit. This is almost always normal. The outdoor unit may leak if:

• The air conditioner is for heating. In this mode, condensate is formed in the outdoor unit and flows out of a special hole located at the bottom of the unit. Sometimes a drain hose is inserted into the hole. If it is, but it flows from the block itself, it is likely that the drainage is just clogged and you need to clean it.
• The air conditioner has been running for a long time. During prolonged operation for cooling, condensate may form on the taps of the freon pipelines and some other nodes. As a result, you will see water dripping from the outdoor unit.

It is not normal for the refrigerant pipes on the outdoor unit to be heavily iced. If you see a snow coat on the pipes coming from the outdoor unit, check out our material “Why air conditioner pipes freeze over”.

What to do to prevent boiler leaks

Leakage can be avoided by taking preventive maintenance of your equipment in a timely manner.

To protect the boiler from corrosion, it should be periodically treated with anti-corrosion agents, which can be found in abundance in any specialized store.

To avoid repairs due to burnout, you should purchase the device only from a trusted manufacturer. Additionally, you should regularly monitor the operation of the boiler, make sure that it works without overloads and does not heat up to the maximum possible temperatures.

To prevent leaks due to high pressure in the equipment, the condition of the valve and pressure gauge should be constantly monitored. When detecting even small faults. They should be removed as soon as possible. Additionally, at least once every six months, it is necessary to check the diaphragm valve.

Failure to comply with these recommendations threatens equipment failure and costly repairs, and in the worst case, the purchase of a new boiler.

The principle of operation of the equipment

A split system is a climatic equipment for domestic or industrial use, consisting of two blocks: indoor and outdoor. Each of the blocks has its own purpose and consists of different elements.

The inner part contains in its housing an air filter, a powerful fan and a coil that allows you to cool the air. The outer part consists of a compressor, a capillary tube, a fan and a coil condenser.

Split system is attractive for owners of large and small premises. It doesn't take up much usable space.And the modern design of the equipment allows you to complement the interior of any room.

All split systems have the following classification:

• Wall-mounted - their power is up to 8 kW;
• Floor-ceiling - their power is up to 13 kW;
• Cassette - their power is up to 14 kW;
• Channel and column - their power is up to 18 kW.

Less commonly used are central and roof-top (rooftop) installations.

The air conditioner compressor contains freon, which is a working fluid used to cool the air. It is fed through thin copper tubes. In the indoor unit this liquid cools the air supplied from inside the room or from outside.

If the split system is switched to heating mode, then freon will already evaporate in the outdoor unit, and conditioned in the indoor unit.

The main reasons for the appearance of water

A malfunctioning drainage system is the main reason for the appearance of water from the air conditioner. But there are others:

• Clogged filters. Water drips from the air conditioner directly into the apartment. The intensity of the leak depends on how hot the room is. If the filter elements are very dirty, the equipment may begin to suck air from the drain. Comprehensive filter cleaning is required.
• Blockage in the indoor unit (on the evaporator or fan). The evaporator contributes to the intake of heat from the air and is located in the indoor unit of the split system. The fan is an important element of air conditioners. Available in both indoor and outdoor units. In the indoor unit, the fan provides forced air circulation through the heat exchanger (another element of the indoor unit). If dirt accumulates on the evaporator or fan, this worsens the heat transfer of the device, a snow cover forms.As the cover melts, it turns into water, which forms outside the drainage system and flows outward from the indoor unit. Pollution leads to a deterioration in the performance of the air conditioner (the unit does not cool the room well). The situation will be corrected by a comprehensive cleaning.
• Indoor fan failure. If a fan failure causes a decrease in the speed of rotation of the blades, frost will form, which, after melting, flows out of the indoor unit. To fix the problem, either repair or replacement of the fan will be required.
• Lack of refrigerant. The refrigerant system may leak refrigerant (refrigerating fluid) or naturally evaporate. The problem is accompanied by the appearance of ice on the evaporator, which, when melted, will splash from the indoor unit of the air conditioner. If the device is equipped with a diagnostic system, an error message will appear on the screen: “lack of refrigerant”. Refueling the system with freon (special hydrocarbons used in refrigeration as a refrigerant) will help restore the evaporated refrigerant. In the event of a leak, the cooling system must first be sealed and then refilled.
• Clogging of the capillary system (in non-inverter equipment). The capillary tube is an important element of the refrigeration system. Its clogging is a common problem in this unit of air conditioning devices. Clogging of the tube leads to a deterioration in the circulation of freon. In this case, the evaporator is covered with snow, there is frost on the elements of the outdoor unit. The split system loses its ability to effectively cool the air (even if it works continuously). The situation will be corrected by purging the capillary tube with special equipment (under pressure).In case of severe clogging, hydraulic cleaning with solvents is used. In some cases, the tube has to be replaced with a new one.
• Faulty thermostatic valve (in inverter air conditioners). The expansion valve acts as a capillary tube, but unlike it, it has adjustments. Violation of the settings or breakage of the valve leads to a change in pressure inside the device and to the boiling of the refrigerant. The air conditioner stops cooling properly, the evaporator, a thin tube of the external unit are covered with snow and ice. The expansion valve needs to be repaired or replaced.
• Failure of the temperature sensor (in those models in which it is provided). If the sensor fails, the temperature of the cooling element drops. If the fall is excessive, the indoor unit of the air conditioner freezes and water starts to run out of it. In these cases, an urgent replacement of the sensor is required.
• Failure of the control board (control module). When the control unit fails, a leak is sometimes accompanied by program failures. The air conditioner stops working efficiently. The board needs to be repaired or replaced.

Reasons for dismantling a household split system

It would seem that the obvious and main reason for the decommissioning of air conditioner modules is the complete expiration of the declared period of operation of this equipment.

Indeed, it is best to replace an exhausted climate device with a new one. And this practice is quite common among owners of used air conditioners.

Not the best example dismantling the external module of the household split system. This method of removal is a direct violation of safety regulations. Other methods must be used

Meanwhile, it is also necessary to dismantle the split system if the main technological equipment fails, for example, a refrigeration compressor. We recommend that you familiarize yourself with the compressor diagnostic methods and repair tips in more detail.

This can happen at any time, regardless of the established terms of operation. In any case, it becomes necessary to dismantle the external unit of equipment.

Removal of air conditioner units is not excluded in order to transfer the system to another installation site. For example, when the owner of the device changes from one place of residence to another.

A similar dismantling option, albeit infrequently, is noted in everyday life. In any case, in order to independently dismantle the air conditioner without damaging the equipment, you need to have certain knowledge.

How to solve the problem?

Eliminating most of the indicated problems can only be done by qualified craftsmen, who have all the necessary tools for diagnosing refrigeration equipment in their arsenal. Given the high cost of a special tool, the high probability of error and the danger of some operations, calling a specialist is more appropriate than trying to solve the problem on your own.

PromHolod Group of Companies is a team of experienced, qualified specialists. Our masters work quickly, accurately identify the problem and find the most rational solution. To make sure of this, the company additionally provides a guarantee for the repaired equipment.

Leak elimination methods

So, we figured out the reasons.Now let's talk about how and with what to close the hole so that you do not have to buy a new heating boiler. Strictly speaking, welding is usually used to repair metal products. To do this, you need to follow a few simple steps.

1. Disconnect the boiler from electricity or wait for the fuel to burn out in it, as well as for the equipment to cool down.
2. Drain all coolant.
3. Disconnect the heat exchanger.
4. Weld or solder the hole.

Of course, for this you need to have at least some skills in working with a welding machine or a soldering iron. But you can do without welding. The first three actions are performed in exactly the same way: turn off and drain the boiler, disconnect the heat exchanger. And then apply "liquid welding" according to the instructions.

Perform all these actions only when you are at least relatively confident in the result. If in doubt - better call the master

This is especially important in the case of gas boilers, where any poor-quality work can lead to very negative consequences. Therefore, for their repair, it is necessary to hire specialists who have a license for the corresponding type of activity.

Good luck!

Possible malfunctions and ways to eliminate them

Heating mode does not turn on

Often, users are faced with the fact that the air conditioner does not work for heat even after an acceptable period of time. What is it connected with? There are several reasons why the air conditioner does not turn on heat:

• The air filter system can be heavily polluted with lint, dust and debris. You will need to clean all its elements;
• Sometimes there is a power failure of the remote control.It is worth removing the batteries for 5 minutes or replacing them with new ones, and then try to start the device again;
• If before that there was a power failure, you can turn off the power to the split system, and start it again after an hour by setting the maximum heating temperature;
• Failures occur in the control system of the indoor unit, then the light indicators on the panel indicate this and the error code mode goes into error code mode;
• The operation of the air conditioner for heat is possible in unacceptable temperature conditions of the outside air. Many modern chillers are equipped with protection algorithms that prevent the compressor from starting in such situations. It can be said that this is “protection from a fool”;
• It is likely that the air conditioner does not turn on for heat due to inadequate pressure. It is worth checking its "liquid" and "solid" indicators.

Why does the air conditioner sometimes turn on for heat, and then abruptly stop blowing, and the curtain on the indoor module closes? If the diodes go out at the same time, and after restarting the same thing happens, then the device is faulty. It is necessary to call the master.

Noise at work

There is also such a problem as the buzzing of the air conditioner when working on heat. Where to look for the reason?

• This may be the norm. Some models are quite noisy;
• If the hum is monotonous, then the reason may be in the compressor, which simply cannot cope with the load, or the evaporator in the role of a condenser does not pull the heat load. Possibly overpressure. It is worth checking whether the volume of freon corresponds to the permissible values;
• Another option why the air conditioner is buzzing when working on heat is the contamination of the filters and the fan of the indoor unit.The device cannot take in a normal amount of air;
• There is a possibility that the fan is damaged and catches on something;
• It is worth checking the freon line, as its poor-quality installation causes similar problems. Somewhere there may be creases and bends;
• It is possible that the air conditioner, when working on heat, starts to buzz due to insufficient voltage in the network;
• The evaporator temperature sensor (on the switch) is responsible for stopping and starting the fan motor at the outdoor module. It may be defective.

The main reasons why air conditioners do not turn on for heat or hum when heated have been considered.

Blowing warm air instead of cold

Now another question arises, why does the air conditioner blow warm air when cooling is needed? There are many reasons, so it is worth understanding:

• Check if the mode is set correctly;
• Look at the degree of contamination of the radiator grilles and filters. Air does not pass, so freon is not cooled;
• There may be problems with the voltage in the network (it is simply not enough), or the integrity of the interconnect wires is broken;
• Poor installation: lack of evacuation, leak tests and insufficient filling of the circuit with freon can provoke such problems;
• If the capillary tube is clogged with debris, then warm air may blow from the air conditioner;
• Malfunctions of pressure and temperature sensors, compressor or fans are also manifested by similar features of operation.

Clogged drain hole in the freezer compartment

If liquid flows from the freezer into the refrigerator section, then the drain hole is probably clogged.

• Visually. A large amount of water and ice appear in the apparatus, located closer to the door.
• Solution.Turn off the device for at least 2 days to thaw it, wipe it dry, and try turning it on. If the ice began to appear again, then you will have to remove the back wall of the freezer. There you will see a reservoir for excess fluid and a drain tube. The opened hole is carefully cleaned with dropper tubes so as not to damage the channel itself. If you are not confident in your abilities, then it is better to call the master.

What to do?

Sometimes the overheating of the engine is due to the fact that the freon charged in the air conditioner is simply not suitable for your car. This usually happens after the next charge of the air conditioning compressor with a refrigerant of the wrong type that should be used in your car. Also, the motor can also warm up due to the banal insufficiency of freon in the air conditioning system. In this case, depending on the problem, either charge the air conditioner with the correct freon, or charge the refrigerant to the maximum.

It is worth noting that if the wrong type of freon was poured into your car or there is not enough of it in the system, then when the air conditioner is turned on, insufficiently cold air is supplied to the passenger compartment. So if your air conditioner stopped cooling the interior normally, and the engine started to warm up, this is the main sign that something is wrong with freon in your air conditioning system.

An air lock in the air cooling system can also cause the engine temperature to rise while driving with the air conditioner on. The thing is that the air plug interferes with the normal circulation of the coolant. As a result, the wrong pressure is formed inside the system, which slows down the circulation rate of antifreeze.This leads to the fact that the heat from the motor is not properly removed.

Another problem that often leads to engine overheating is insufficient antifreeze in the cooling system.

That is why it is so important to check the coolant level periodically and add it to the maximum level if necessary. We also recommend that you change antifreeze every 2-3 years, depending on the intensity of use of the machine and on weather conditions in winter and summer.

For example, if the car is often stuck in traffic jams in hot, dry summers, then we recommend changing the antifreeze every 2 years. The same goes for harsh winters.

A malfunctioning thermostat can also be a likely cause of the engine overheating when the car is stationary or moving at normal speed.

That is why it is so important to use only high-quality original thermostat. In no case do not save money by buying dubious quality non-original thermostats

You risk overheating your car. And this is fraught with engine damage.

Including overheating can also occur if the radiator cap malfunctions, which, as a rule, has a special spring valve that helps to relieve excess pressure from the cooling system resulting from the heating of antifreeze.

If you are facing the problem of engine overheating while driving, pull yourself together and don't panic first. Panic can really lead to stupidity. As soon as you see that the coolant temperature sensor on the tidy crawled up, immediately slow down and stop the car as soon as possible.Further, in no case turn off the engine. Otherwise, this will lead to a sharp drop in engine temperature, which is fraught with huge problems. So, stopping the car with the engine running, turn off the air conditioner and turn on the interior heating at full power. So you can cool the boiling antifreeze. Then get out of the car and let the engine run with the heater on for a few minutes. Only then can you turn off the engine.

Now your task is to determine the cause of the engine overheating. To do this, use the features that we described. Fortunately, most of the causes that can lead to overheating of the car are easily fixed on the spot. If you cannot remove the cause of overheating, then it's time to contact a technical center for diagnostics and car repair. It is advisable to call a tow truck in this case.

To avoid engine overheating problems, there are many golden rules, in particular the use of the correct coolant for a particular car model (all cars use different types of coolant that differ in color and properties). If you purchase a concentrated coolant, you must remember that you can only dilute it with distilled water. You also need to regularly monitor the condition of the thermostat, radiator, pipes through which antifreeze circulates, as well as the condition of the air conditioner, conducting its annual scheduled maintenance.

Air conditioner leak, questions and answers

According to information about air conditioner leaks, the following popular questions and answers can be distinguished.

Can you turn on the air conditioner if it flows?

Yes, but the problem won't go away on its own.In some cases, you risk damaging the air conditioner. For example, due to freezing, radiator pipes can crack. Therefore, it is better to look for the cause and eliminate it.

Water comes out unevenly from the drainage tube - sometimes it doesn’t flow at all, sometimes it flows quite strongly. What could it be?

Most likely there is a slight kink somewhere in the drainage system. Water accumulates in it, and when it reaches the maximum, it flows out. This will not affect the operation of the air conditioner. But over time, a plug may form in the place where water accumulates.

When I turn on the air conditioner, it starts spitting water. Then it will work for an hour and everything is fine. What is the problem?

You have high humidity in the room. While the air conditioner is not running, moisture accumulates inside it. After turning on the air flow, it is sprayed out.

Where does the water in the air conditioner come from and why does it start to drip

The main function of an air conditioner is to cool the air. A number of mechanisms located in the indoor and outdoor unit cope with this task. During operation, condensate forms on the evaporator (cooling element), which must drain into a special container, and then through the drain pipe it is discharged to the street.

Due to various malfunctions, the condensate formed on the evaporator may drip past the tank, leaving drips on the walls next to the unit, enter the fan or flow out of the tank without passing through the drainage route. Before determining the course of repair work, you need to find out the exact cause of the malfunction.

How much condensate does the air conditioner emit

The amount of condensate formed is determined by the power parameter of the device according to the following formula: for 1 kW of cooling capacity - 0.5-0.8 l / h of condensate.That is, if the house has a 3 kW split system, the average volume of condensate will be 1.5-2.4 l / h.

Proper care - extend the life of your own air conditioner

Many owners of split systems are looking for ways to avoid breakdowns, however, competent and timely care and cleaning will also be sufficient. High-quality equipment can serve properly for many years, but if you do not monitor its condition and do not carry out fairly simple procedures, then the maximum that such negligent owners can count on is 2-3 years.

The very first thing to take care of when buying a new climate control equipment is the most optimal place for its installation and the correct adjustment of the operating mode. Cooled air should be evenly distributed throughout the space, and not directed in a single stream to one point.

You should also periodically check the condition of the filter, which from time to time becomes clogged and reduces the efficiency of the air conditioner. In order to correct this situation, you will need to remove the outer cover, remove the filter and rinse it thoroughly. And to fix the split system on your own in this case is not difficult and does not take much time. Moreover, some models are already equipped with special indicators that allow you to find out about the condition of the filter and the degree of its contamination. If it has not gone through cleaning for a sufficiently long time, then it will not be possible to do without special solutions.

Another important nuance that should be taken care of in a timely manner is the refueling of equipment with freon, which plays the role of a coolant. Without this component, the air conditioner simply will not be able to carry out its work. And if split system installation was performed insufficiently, freon may leak. As a preventive measure, it is recommended to refuel the air conditioner with such a coolant once every 1.5-2 years.

Why is the air conditioner getting colder?

One of the reasons for the poor performance of the air conditioner is the lack of freon or a decrease in its amount. Freon gas itself sooner or later disappears, and this is quite normal. Therefore, it will have to be refilled once every 2-3 years. But also freon can erode due to breakdown of the radiator. And although this most often happens in car air conditioners, such a breakdown also occurs in ordinary household ones.

The air conditioner may start to work poorly for various reasons. Therefore, the most important thing is to call the service department and invite an air conditioner repairman to your home. If the equipment is under warranty, you can contact the store for help, where the breakdown will be fixed for free.
