OP here. Yes it is a Schwintec closet slide. That other brand was created by fat fingers and small Kindle. Thanks for the helpful responses. I have reset the controller with no joy. Double checked for obstructions. Glad it is stuck in rather than out.Checked switch on panel to be sure all wires were connected. Cleaned 30 amp fuse.
I'm hesitant to get deeper into it on the road. Wll be in Fl for a month soon. Am going to have it looked at then if needed once I go through your suggestions again. Thanks very much.
