Change an electronic air conditioning board

 Is it usually expensive to change an electronic plate of the air conditioner for a new one by fault?
⇒ What is usually dangerous, since a failure in the placement of one cable by another can burn and has no guarantee from the manufacturer.

In this post, we will see how to change an electronic plate of the air conditioner, either from the indoor or outdoor unit. This is a very delicate job and I only recommend that you do it if you are a professional handyman with knowledge in appliances and electricity, in the electronics are mixed with the light. In this article, we will not go into the determination or diagnosis of the air breakdown that results in the failure of the plate. But we start that you already know with certainty that the problem has the plate and you want to change it.

You have 2 options, disassemble it to have it repaired with a 3-month warranty normally, buy a new one that usually has a 2-year warranty. Depending on the price of the plate, and that of the machine, you would have to decide which option interests you most. The pros and cons of each option are that in the case of repair and that it does not work then you will not know if there is another failure in the air or that the repair is not well done, since a technician who repairs plates never gives you It will give 100% guarantee that the board is in perfect working order, although on the other hand, it is usually much cheaper to repair it than to buy it new.

Buying it new from the manufacturer you will make sure you have a plate that works although it will be much more expensive. In both options, the bad thing is that neither of them has a guarantee since the technician who repairs it does not give guarantees and t manufacturer gives a guarantee for manufacturing defect. If you mount the plate again and it breaks, the manufacturer will claim that you have another fault in the machine that has broken the plate, so it would not be a manufacturing failure and the warranty will not cover you.

9 Quick steps to replace an electronic air conditioner board by failure

What we are going to explain is the methodology to follow for changing any air plate. Since each plate and brand has different connections, we will explain the method to follow to make the change.

1.- The first thing is to cut the electrical supply of the device and using a tester make sure that it is really cut.

2.- Remove the cover of the air conditioner to be able to access the interior, normally the plate will have some protection such as a sheet of the plastic cover. Remove it carefully and before removing it check if it has cables attached.


3.- When you have the plate insight before disconnecting anything, take several photos of other plates in general and small details such as the location of the screws, connection of the cables by colors, tabs, and catches. Do not have problems making the photos you need, whether 10 or 20, do not work with the memory that can play tricks on you.

4.- It would also be convenient to make a small connection scheme.

5.- First remove the fastening screws of the plate. to be able to move it If it is the power plate, it usually has two screws that hold it to an aluminum heat sink and will have therm silicone.

6.- Once you have the loose plate and can handle it (use gloves to avoid leaving traces of grease and dirt on the plate), go disconnected the different pins. In most cases, the plugs will go by color and shape, so as not to make a mistake in the connection, but still take pictures to avoid mistakes.

7.- Once you have disconnected the plate and you can remove it or take it to repair or replace it with the new one.

8.- Now you just have to put the new board and connect it in the same way following the photos you have taken. Very important in the case that the other plate carries thermal silicone, please also to the new one.

9.- Once connected and on the cover, close the machine and turn on the power. If you ha connected everything correctly it should work if that was the problem.


Is it worth investing in a professional technician to do the job of changing the plate? 
Absolutely, YES, because if you are not a handyman or do not have knowledge of electric and portable ac price in Bangladesh, it may not be so easy, especially if the machine has difficult access.
My recommendation is that you call an authorized and qualified technician who is professional and with the papers in order, as this will ensure that you have the necessary knowledge to be able to perform the work in a professional, fast and guaranteed way.

It is better to INVEST and I say it with capital letters in a professional and qualified technician who is a prudential time has been able to make the change and verify its operation, than not to call an unqualified person (who in most cases does not have RC insurance) , that by saving you some money, you can burn the electronic plate of the new air conditioner and it will cost you to buy a new one  (since the manufacturer washes you hands), or the same has no experience and throws a few hours (which you will have to pay him), to make the change or by an oversight cause a short circuit that burns the plate or another device of the machine.

This case is more common than you can imagine and many people have spent their mon without getting a professional service in return.
