Troubleshooting Introduction
This troubleshooting chart outlines some common problems, their causes and possible corrective actions. If any
part or serial number information is available, provide it to the service technician when asking for assistance.
The Lippert Slideout System is only one of four interrelated slideout room system components. These four
components are: chassis, room, coach, and Lippert Slideout System. Each one needs to function correctly with the
others or misalignment problems will occur.
Every travel trailer has its own personality and what may work to fix one trailer may not work on another even if the
symptoms appear to be the same.
When something restricts room travel, system performance will be unpredictable. It is very important that slide
tubes be free of contamination and allowed to travel full distance (Stroke). Ice or mud buildup during travel is an
example of some types of contamination that can occur.
When you begin to troubleshoot the system, make sure the battery is fully charged, there are no visible signs of
external damage to the system and that all connections are secure.
During troubleshooting, remember that if you change something, that change may affect something else. Be sure
any changes you make will not create a new problem.
