Frequently Asked Questions
Q: How do I know if this fits?
A: Check your existing controller for part #13398-DO. Compatible with Lippert/Schwintek dual-motor systems. Contact us with your slide model if unsure.
Q: Is it plug-and-play?
A: Yes. OEM-compatible connectors — unplug old, plug in new. No wiring or splicing needed.
Q: My slide moves unevenly — will this fix it?
A: If your current controller has failed (one side moves, other doesn't), this replacement restores proper dual-synchronous operation.
Q: What causes controller failure?
A: Water intrusion, voltage spikes, motor overload, and general age. Exterior compartment controllers are most vulnerable.
Q: Can I install this myself?
A: Yes — basic DIY. Disconnect battery first. Most installations take under 30 minutes with just a screwdriver.
