Main PCB fix for Mini Split outside unit Whirlpool WA5060Q
So I have this mini-split unit Whirlpool WA5060Q, the fan on the outdoor compressor refuses to turn on, the console inside the house works fine but it's not cooling of course. When I opened the outdoor compressor I can see there's a scorched trace that ends in a "DCFAN" connection (image below), no wonder the fan doesn't turn on.

I don't know much about PCB repairs but would replacing the trace be the fix? or is there potentially something broken that burned the original trace and will burn the new one I put in?
I'm just trying to get an idea of what I'm getting into before I dive into it
Esta é uma boa pergunta?

I think the first thing we'd need to know is what's on the other side of the board? Since there aren't any components on the side we can see, there's nothing there that can actually burn up; whatever got your board so hot happened on the other side and was hot enough to scorch this side as well.
So if you can dismount the board and get us some pictures of the other side, we might be able to give you some ideas. A close-up picture of that burned area and the connector next to it wouldn't hurt either.

Hi Jerry, it took me a while but I managed dismount the board and upload a few more pictures, thank you
