Major breakdowns of air conditioners

Malfunctions of home air conditioners can be very different in nature. Having in its structure rather complex mechanisms, such equipment requires special attention from the user. And, if you leave the air conditioner without the necessary maintenance, it will very soon stop working. All breakdowns of air conditioners in general can be classified by the following features:

• mechanical - causes associated with the breakdown of the internal mechanisms of the device.
• electric - causes related to failure of electronics.

The main causes of breakdowns

As mentioned above, the care of technology - the key to its normal functioning.We give the most common user errors that cause various malfunctions of air conditioners.

Dirty filter

Contamination of the internal filter not only disrupts the normal circulation of air inside the system, but also provokes disruptions in the operation of refrigeration equipment, which leads to the accumulation of ice on the copper pipelines. Consequently - dripping water from the case of the device.

Flush the filters approximately once every three weeks. To remove dirt from the system, rinse the filters under running water, dry them and return to their original position.

Freon leak

Even with the perfect operation of the air conditioner freon leak is inevitable. The normal leakage rate is 2-3% per year, which is equivalent to 150 grams. In order to prevent damage to the device, it is necessary to carry out refueling once every 2-3 years, which will raise the level of freon in the system to the previous value.

However, there are cases where leakage rates exceed the established norms. The main feature characterizing this situation is ice and frost formation on special copper pipes that ensure system operation.Such a leak can provoke a whole range of mechanical problems.

The operation of the apparatus in the winter

Most models of air conditioners are not adapted to work in the winter. The temperature range is from -7 to +40 degrees. To work in the winter time, the air conditioner needs special technical training.

Operation unprepared apparatus in the winter is capable of disrupt compressor operation and drainage system. Water arising during the operation of the device will not be able to leave the system due to freezing of drainage. Consequently, all the water will flow directly into the room in which the air conditioner is installed.

Main types of faults

Consider the main problems of air conditioners and how to eliminate them. Immediately make a reservation: if your air conditioner has broken, it is strongly not recommended to perform troubleshooting yourself.

In case of damage to the internal mechanisms by the buyer, the manufacturer disclaims the obligation of warranty repair. 

Bad room cooling

This fault 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 desired temperature in the apartment. This may be due to a sharp change in the climate in which the device is operated. The average temperature range of the device is an indicator from -7 to +40 degrees.

If the failure is not associated with a change in temperature, it means that an internal failure has occurred in the operation of the device. Determining the cause on your own is quite problematic, therefore it is recommended to carry out maintenance at the first signs of a malfunction.

Timely diagnosis of equipment for cleaning from dirt and dust, avoids many problems.

Compressor failure may be the main reason for the emergence of such malfunctions split systems. Correction of damage is a matter for a qualified specialist.

Short cycle of the apparatus

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

• failure in the settings;
• the control board broke down;
• failure of the thermostat;
• radiator pollution.

The external radiator, especially in the summer, is often exposed to dust, lint, dirt, etc. Clogged, it provokes overheating of the entire system, which leads to stopping the operation of the device. The solution to this problem is radiator flushing strong water pressure.

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

Dripping condensate from the indoor unit

Dripping condensate from the indoor unit can be a signal that your equipment is malfunctioning. The probable cause could serve clogged drain tube. 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 the original position.

Clogging the drain pipe causes 90% of cases in which condensate drips from the indoor unit. You can easily perform this cleaning procedure without the help of a qualified wizard.
