Yes slides have been known to do that and has scared people as to what has been going on.
What's been found radio frequencies
can activate the control and mice or other rodent can.
Will do a search and see what we find.
Had one owner with a daughter on bed watching TV when suddenly the bed started moving, maybe we will find that thread.
Here is the search.
You can do on some posts in the first thread of search and clean 12v plug to control board, check the battery connections on fuse panel for loose wiring of that control board and what ever else you may find on the search.
A new control board may be in order after doing the checks if it still fails.
