Lippert V-Sync II In-Wall Slide-Out Controller | 13398-D0 | OEM

Restore controller function to your Lippert In-Wall (Schwintek) slide-out system with the Lippert V-Sync II Slide-Out Controller (Part #13398-D0). Genuine Lippert OEM replacement controller for In-Wall slide-outs — the "brain" that synchronizes the two IG-42 motors driving your slide. Exact-match component, no assembly required.

⚠️ 13398-D0 Supersedes 13398-C2

The 13398-D0 is the current version that has replaced the older 13398-C2. If your existing failed controller is a 13398-C2, this 13398-D0 is the correct current replacement.

What This Controller Does

The V-Sync II is the central brain of your Lippert In-Wall (Schwintek) slide-out system:

• Synchronizes the two IG-42 motors that drive each slide-out
• Tracks motor revolution counts from the magnetic encoders
• Sequences slide-out extension and retraction
• Detects faults and reports error codes (per TI-177)

When Controller Failure Symptoms Show

• Both motors unresponsive despite adequate battery voltage
• Persistent error codes even after clearing obstructions
• Slide-out won't respond to switch commands
• Controller powers on but won't execute commands

Before replacing the controller, verify against motor and wiring issues — many field problems trace to motors, harness connections, or battery voltage rather than the controller itself.

⚠️ Verify Compatibility Before Ordering

Lippert In-Wall systems have used several controller variants over time. This 13398-D0 is designed for In-Wall slide-outs using the V-Sync II architecture. Consult your owner's manual or contact Lippert with your RV VIN to confirm this is the correct controller for your system.

Companion Components — Schwintek In-Wall Motor Family

If you're diagnosing a slide-out failure and need to service the motors instead of (or in addition to) the controller, we carry the full Schwintek motor family:

• Lippert 240015 In-Wall 5mm shaft motor — older installations
• Lippert 236575 In-Wall 10mm 300:1 motor — most current installations
• Lippert 287298 In-Wall 10mm 500:1 high-torque motor — heavy slides

How the Lippert In-Wall (Schwintek) System Works

The In-Wall system was launched more than 5 years ago and is now standard equipment across more than 70 RV brands — making cable slide-outs largely obsolete. The V-Sync II controller manages:

• Two IG-42 motors per slide — one in each upper corner of the wall assembly
• Magnetic encoder feedback for revolution counting
• Synchronized motor operation — compensates for one motor lagging or leading
• Error code reporting for diagnostic troubleshooting

Effortless Installation

Exact-match component design means installation is hassle-free:

• No assembly required
• Genuine OEM part — no calibration or programming required
• Direct plug-in fit using existing wiring harness

⚠️ Cosmetic Note

These new units may have minor markings on the casing from storage. Purely cosmetic — does NOT affect function.

In-Hand — No Direct-Ship Delay

Units are in-stock and ready to ship — NO Lippert direct-ship lead time applies to this listing.

⚠️ Professional Installation Recommended

Involves 12V DC electrical wiring and integration with the In-Wall slide-out system. Installation should be performed by a qualified RV service technician. Always disconnect the coach battery before removing or installing the controller.
