"stuck in the full deployed position and I had a hard time starting it back to stow position."
Does this mean you succeeded in getting it to close eventually?
If so, there may be a circuit breaker which overloaded and then reset after a period of cooling. Have that from time to time with our hydraulic slide mechanism, usually results in an "oh sh-t" moment until I remember to look for a strain point and ease it before trying again after a few minutes.
Could be something binding or just too much draw from the power supply at that moment.
If you did not get it closed, that is a different set of issues :(
