In almost each and every case premature gear/track failure has been due to some sort of debris getting stuck in the tracks that the worm gear engages with. Usually this debris is part of the weatherseal around the perimeter of the room that gets caught and chewed up. In 2 cases is has been due to the system ingesting a fastening screw that had pulled loose after the weatherseal became lodged in the track and pulled everything out.

In several cases the mounting screw that pins the motor and prevents from spinning around and around has sheared off causing it to wrap up the wiring harness and shred it. Harnesses are not easy to replace in these.

The connector they use to connect the motor to the controller at the motor side is a small flat very fragile connector. The slightest tug on the wiring and the wires pull out of the connector. Unfortunately, this connector is positioned right behind the weatherseal bulb on the inside that the room opens against to create a tight seal. It doesn't take many cycles for it to completely smash the connector.

The problems you describe are due to poor design and inadequate materials; not "how" the system works. There are numerous other posts attributing failure to motors too weak for the weight, aluminum shafts that twist and bend, gears that disintegrate, etc., etc.

Thanks to all for the information. A recap of the comments appears to indicate: the system works well for the first 15 or 20 times then self destructs; the system works well on the smaller slides but not the larger or full wall slides; the system fails more often when moving the kitchen slide with refrigerator, stove, microwave, sink, fireplace, etc. Someone said they have a part gear motor, part hydraulic slide that was working? Is this the way Thor and Schwintek are moving? If so would this be an acceptable modification that may be dependable? My hydraulic system works well. If anyone knows of a web site showing past and current schwintek installation pictures please let me know. If no changes I guess my 2007 Forest River Georgetown 373 will go another 10,000 miles before I look to trade! Thanks Glen

On 2015 Mirimar and Palazzo models they are putting a third track on the full wall slides. Haven't heard yet if this has solved the issues they were having with the Lippert Schwintek system on the big slides.
