Just looked at a video and you have cable slides with cables at the top and bottom.

Is there any binding with the slide or the motor sounding as if it's straining? Maybe something is caught causing it to overheat an automatically resetting breaker or maybe it's just a weak breaker. I am assuming the slide itself is in alignment and fully opens/closes.

Not a lot of mtce. on the slides other than keeping them adjusted. You can clean the cables and check them to make sure they don't fray or start rubbing on any of the little metal guides. Don't use anything on them that attracts dust/dirt.
