I've developed a problem with my large slim-rack slide. When extending and retracting, the slide abruptly stops at the same place. Motor does not strain, just stops. After a few seconds, pressing the switch again allow the slide to continue. Seems more electrical than mechanical otherwise motor would strain (more than normal). But why is it able to start up again? I've checked for obstructions under the slide floor where the rollers are, and the racks. Stops same place, every time going in or out. Any help will be appreciated.
BTW, where is the controller for the Slim-Rack slide on the Northpoint 377?
