On the controller there is a very small adjustment screw on the lower left corner. You can use a very small screwdriver to turn the screw in a clockwise direction.
Be careful not to move it too much!
I had a similar problem just recently where as the motor would just hum when I tried to open the slide, I may have moved the screw a half minute on a 60 minute clock to allow the slide to operate. If your adjustment is too much, you could destroy the motor or other components of the drive unit, so, proceed with caution. .
What brand slide is this?
