Main slide issue on one side

Hi all,

I'm having issues with my main super slide. When bringing the slide back in it's as if one of the motors loses power or the communication signal is lost. So the one side just stops. I then release the button (this happens regardless if I'm using the manual switch or the button on the remote control) and extend it back out fully with no problem. I then bring it in and same thing happens on the same motor every time.

I have gotten around this by pressing the button for about 3 seconds at a time bringing the slide in incrementally then releasing the button. I repeat this until the slide is in. This obviously takes a long time and is not ideal. But the motor doesn't lose power for those 3 second intervals. Only when I keep the button pressed down does the motor seem to lose power and stop. This causes the slide to start getting out of time so I have to extend it back out all the way again to start over again.

And the motor doesn't ever seem to lose power when the slide is extending out. Only when coming in. What is going on here?

Thank you for any suggestions,
Chris
