Generel Line split Air nocitioner

[AdamHUN]

Hello!

My name is Adam and I have a problem.
My company bought the General line 9000/R407 Air conditioner.

But it is bad.
There is a panel on the side of the climate if I know it well this is a MAIN CONTROL BOARD If I have true.

The engineer said this is bad, but there are an any kind of circuit diagram or anything else unfortunately based on what it would be possible to look at it we the bad one on the panel.
You would be able to help it in a dog for me? or to give an idea?
Greet too Adam
