Unfortunately this is a grossly flawed system. You hit the nail on the head. This system is under engineered and can't handle a heavy slide. My slide is probably have the weight of yours and I've had chronic problems with motors and rails. It helps to keep the slide as light as possible. I only store a few very light weight articles in the cupboards and other compartments. I even remove the kitchen table before operating the slide. Now, if I could only find a way to remove the refrigerator.
