Thanks,
It's the original board. I wonder if I remove it and take it to my local RV dealer if they could test it for me? I will call them tomorrow and ask.
I was just wondering what you guys thought of the symptoms?

If you have a multi meter you can do this your self in 5 mins. I think just by removing it you will clean the contacts and that might help you. If you haven't cleaned all the grounds and other contacts do that also. You say that it stays on for an hr then shuts off. This sounds like the water is being heated and it has reached the temperature of the thermostat and is being shut off(normal).
