Steve, first thank you for your help. Too bad we did not find a problem. I do have the manual, but it will not be of any help. When it discusses a problem with the controller, it says to contact the company. But remember, they are gone. Perhaps someone else on this forum will read this thread and come up with a suggestion, or suggest someone I could send the board to for help. I did contact one company, but they wanted a minimum of $300 just to take a look. Have a great day. Tom.
