When I turn on the air conditioner the light goes out and I stay in the dark


This was not happening to me last year!
It is one of the most common problems or failures that an air conditioner usually has. There are multiple reasons why this could happen. Some of the causes may be in the outdoor unit and others in the indoor unit. Let's look at some causes separately.
⇒ Causes of the outdoor unit that make the light jump, when I turn on the air conditioner

We must take into account that the outdoor unit is precisely outside and is exposed to environmental phenomena, so if it is not well installed or sealed, it is very easy for water tenter, which would cause the differential to skip. On one occasion I found that they had put an outside machine in a garden with irrigation system, and had not realized that one of the sprinklers was spraying the water near the machine. On windy days, he carried the water to the machine, which caused the light to jump.

Other causes that can cause the power supply to cut is a capacitor failure. When it breaks down, it often causes the differential to jump when the compressor of the outdoor unit is going to start up.
A fault in the electronic board, if it occurs in the part of the transformer, can also cause th light to jump in the general panel since the input voltage is 230V. Although it is always desirable that the problem is not on the electronic board since they are very expensive and often the collar is more expensive than the dog.

The compressors can also cause cuts in the power supply, especially if after having used several years, they remain inactive for several months, since many times they remain blocked and when trying to start them, and not be able to start, they greatly increase the consumption, they heat up and make the thermal jump.

In many cases, they can be unlocked, but in other cases, it is not possible and changing them is also very expensive.

There are more causes in the outdoor machine that can cause the house to go out, although these are the most common.

You can hardly diagnose and repair these breakdowns yourself, so my advice is to call a qualified and authorized professional.

⇒ Causes of the indoor unit that blow

There are several reasons in the indoor unit and that can cause the light to go out. Let's review the most usual. The most common cause is usually due to moisture problems or directly due to water. There are times when the machine, or rather its drainage, is not mounted correctly, and the water does not drain properly, so it stays in the Split and there are times that it beats the container and falls on some wire or electrical contact and It causes the electrical bypa and the consequent power outage.

They are breakdowns that do not occur continuously, because when a while passes or the cables dry, the light stops jumping until the next time waterfalls on them again, which do not have to happen whenever the air, only when moisture or time of use, produces such amount of water that causes an overflow.

A gas leak in a certain area of the Split evaporator could cause a power outage if this leak occurs to the electronic board or the power terminals. It is very rare, but we have found more than one case.
A failure in the transformer of the electronic board of the indoor unit can also cause the power outage, as in the outdoor unit. There are more causes in the outdoor machine that can cause the house to go out, although these are the most common.

Virtually all the checks and measurements that are necessary to perform at an air conditioner to see where the problem may be, require professional knowledge, tools, and devices that you will hardly have at home, so my advice is to call a qualified professional and authorized. Many of these failures are worth repairing and others have to weigh other reasons, such as machine location, current economic situation, etc ...

⇒ Is it worth investing in the repair or having it checked?

Without a doubt, YES, since you cannot be without light in the house. The only thing is that usually, you will not know a priori that the problem is air cooler price in bangladesh unless you have already made some verification that has led you to that conclusion; So the first thing you will have to do is call an authorized electrician to verify the installation and nd out where the problem is, and if it is from the air conditioning machine, and see if the technical miso can solve it or if you have to Call a qualified air conditioning technician.
