Richard,
Where are these 3 control boxes that you speak of located?
When I had a burnt control board on my bedroom AC I tightened the wire connectors and any thing else I could find that might be loose. They were all tight! I had to replace the circuit board; it was burnt too badly.
I also checked the tightness of the wires that clip onto the top of the compressors. Everything was good and tight.
