It looks like the power feed for the outdoor fan motor got burnt. I would definitely check the resistance between the two terminals on the motor connector before I did a board repair. The service manual for your model should have some typical values for reference.
Also, how old is the unit? It may still have warranty coverage. If so, you should be able to send the pics to the manufacturer and get a new circuit board. I'd definitely verify that it's out of warranty before attempting a board level repair.
