Air conditioning will not surprise anyone else. Many of us have this miracle device at home, since the cost of split systems is quite democratic. However, despite all the technological and modernity of such climate technology, it does not always work stably.
There are frequent failures and malfunctions that can confuse even an experienced user. One of the most common problems is that the air conditioner does not turn off or, conversely, does not turn on. Owners of split systems are perplexed: why does the air conditioner not work properly? Why is it not controlled from the remote control?
In this article you will find answers to these and some other questions. We will briefly tell you what is the cause of such malfunctions and what can be done to improve the operation of the device.
The air conditioner does not turn on
The main reasons:
Faulty remote control
An error occurred in the operation of the device
The absence of a winter kit when operating in sub-zero temperatures
The control board is faulty
Let’s analyze each of the reasons listed above in order.
The first thing you should do is check whether the plug from the air conditioner is plugged into the outlet! If it is turned on and at the same time other electrical appliances are working properly in your house, and the air conditioner still does not turn on, then the problem is in the outlet, power cable or other components of the split system.
Only the master from the service center can determine the exact cause, since he has additional tools necessary for a full-fledged diagnosis of the air conditioner.
If there is nothing wrong with the power supply, check the control panel. It is often the cause of the problem that lies in it. First of all, replace the batteries in the remote control and check its operability. If it is faulty, buy a new remote control and try to turn on the air conditioner, following the instructions. It comes complete with a remote control.
Often this is enough for the device to turn on and start working in the same mode. But what if a strange combination of letters and numbers, like E9 or 015, is displayed on the display of the remote control or air conditioner? So the device informs you about the presence of an error in the operation of the split system.
Each modern device is equipped with a well-thought-out system of fuses and protections. When one or another protection is triggered (for example, against overheating), the air conditioner stops working and an error is reported. To decipher the error code, you need experience. And self-repair in this case is also hardly possible.
Another popular reason is the operation of the air conditioner in winter without using the so-called winter kit. If you are trying to start the device when the temperature is below zero outside, the split system may simply not turn on. In this case, you need to purchase and install a winter kit, this service is available in every service center.
The last reason on the list, but not the most important — is a faulty control board in the air conditioner itself. In this case, the board in the device does not perceive the commands of the remote control. Usually, the masters simply replace this part entirely, without doing minor repairs.
The air conditioner does not turn off
Most often, the reason lies in the malfunction of the remote control. To check this, try turning off the air conditioner using the emergency button. It is located under the decorative cover, on the right side of the air conditioner. Press the button once and listen. If the device has stopped making sounds, it means that it has turned off, and the problem really lies in the remote control.
If after pressing, including repeated, the air conditioner does not turn off, then the problem lies in the device itself. In this case, only a qualified master from the service center will help you.
Let’s go back to the non-working remote control. If the device does not turn off due to a faulty remote control, replace the batteries in it and try again. Does the air conditioner not turn off even after replacing the batteries? Get a new remote control and check its performance. In most cases, it is sufficient to replace the remote control.
Now you know why your modern air conditioner does not turn off or does not turn on at all. There may be several reasons and only an experienced master can determine the exact one. We do not recommend carrying out repairs with your own hands, so you will involuntarily shorten the service life of the air conditioner. It is better to entrust this task to a specialist from the service center. We wish you good luck!
