Well my Kelly Controller finally made it back home. No cost and fixed. They said it was the power board inside. They said that the internal components are modular in nature to make repairing easier. So if a component goes bad the component is removed and a new on inserted. Why it failed was not revealed. Not sure they even know. So they did not replace the controller. Power board was just found to be defective and they replaced it. Now I must try again to see if it works properly.
