Russ,

Thanks for the thoughtful analysis. I believe you are right on all counts. I have attempted to keep an eye on these boards and regularly pull the lid off and inspect for obvious problems. Never have seen any sign of board fatigue until I had a total melt down.

For those wondering, this was more than a simple lead getting hot and causing problems. There was a fire inside the metal box and soot was on the wood shelf above the unit. I came close to losing the entire coach with my two dogs inside.

I will follow up with Newell and see what they recommend.

I am going to renew my effort to find a replacement entire AC unit.

Thanks!
