How do you fix and adjust an RV slide-out that is out of sync?

Over 70 RV brands use the Schwintek slide-out system from Lippert, and a slide-out can get out of sync. This happens when the two sides are not matching up when fully retracted or fully extended.

Here are instructions on how to retime your RV’s Schwintek In-Wall® Slide-Out if that occurs, as well as how you can prevent it from happening again in the future.

Retiming Your Schwintek Slide-Out System

What we have here is a Schwintek slide system that is out of time. The way you know it’s out of time is because this side is fully extended, as opposed to this side which is still approximately four inches from full extension. The way to retime the Schwintek slide system is simple. You would go to the switch and depress the out button until the slide out fully extends. You would then depress the in button and bring the slide in 8 to 10 inches. We would then repeat this process a minimum of three times until the system fully retimes. The way you’ll know the system has retimed is because both sides would then extend or retract at the same time. 

The reason we need to run the system in and out three times is to give the system an opportunity to re-sync itself. The Schwintek slide system has two motors that counts revolutions. This is what keeps the system in sync, or parallel. When the system is not fully extended or fully retracted each and every time, the controller loses its zero point. When we run the system in and out three times, it allows that controller to find the zero point.

Preventing Your Schwintek Slide-Out from Getting Out of Sync in the Future

Now let’s talk about preventing your system from getting out of time. When you extend or retract the system, at the end of the stroke, you want to stay on the switch for approximately three to five seconds to assure that the controller is able to recognize the zero point.
