Helpful Advice Acquired from Lippert:
After attending a three day Advanced RV Technician Training Course in Mishawaka, Indiana at Lippert's Training Institute, I wanted to pass on some info that I received about a few Lippert products that may save you time, money, and grief.
Schwintek in-frame slide out systems: What they are finding out is that many of the complaints they are getting are often "user error", or what I think is more to the point: "user was never properly instructed by their dealer". One of the biggest issues is the slide becomes unsynchronized. This means that one side of the slide out room is further out than the other. It may have become unsynchronized due to an obstruction inside or outside of the coach, or what may have happened is that the user did not hold down the switch continuously until the room was fully in or out. It is sometimes possible to remedy this situation by moving the room in and out about 3-6 inches several times until it corrects itself. One of the biggest culprits of this condition is actually weak batteries in the coach which throws off the "hall effect" of the motors. Also, they DO NOT advise lubricating any part of this system, and they DO NOT recommend applying any conditioning products to the rubber wiper seals (it actually destroys them). Warm soapy water is your best friend when it comes to the gear racks and the rubber seals.
Ground Control Electric Leveling Systems: These electric leveling systems can throw error codes and not level the coach. They internally count motor revolutions to orientate themselves and can become uncalibrated under extreme leveling conditions. The best way to reset them is to manually drop all legs about 6 inches (yes even the fronts on 5th wheels, so be sure to have it hitched to your truck). Next you'll want to "Retract All" of your legs and the system will recalibrate itself. As with the above slide outs, improper battery voltage can cause issues as well. They have manual overrides on each motor and in an emergency can be lifted with a drill but NEVER an impact gun, as this will permanently damage them.
One Touch Command Centers: These seem to be pretty good systems, until someone messes with the programming. Best to not touch these unless trained in doing so.
