Safety first: Keep people clear of the RV and jacks, chock the wheels and never crawl underneath a vehicle supported only by leveling jacks. Stop for a bent jack, unstable ground, severe frame movement or hydraulic/electrical damage.

A Lippert Ground Control Out of Stroke message is not asking for another Auto Level attempt. The controller has seen a jack reach maximum stroke without completing the lift, or it has detected an unexpected high-current stall.

The safe response is to reduce extension, improve the site and inspect the affected jack—not to hold Extend until something bends.

Stop the automatic cycle

Release the controls and keep everyone away from the jack path. Note which corner is unusually extended and whether the foot is sinking, hanging over a pad or pressing against an obstruction. Photograph the touchpad message before clearing it.

Understand the two causes in Lippert’s chart

Lippert lists maximum jack stroke as one cause and an unexpected high-amperage stall as another. Maximum travel usually points to a site that is too far out of level or a jack starting too far above the ground. A stall can point to a bent/damaged jack, obstruction, motor problem or wiring/current issue.

Retract before changing the setup

Use the exact Ground Control manual and manual mode to retract the jacks enough to remove the load. If a jack will not retract or the RV shifts unexpectedly, stop and arrange service. Do not reposition the tow vehicle with loaded jacks down.

Once all jacks are safely retracted, relocate to a more level site. Use stable, appropriately rated landing pads as allowed by the RV and leveling instructions; never build a tall, loose stack.

Inspect the affected jack and footing

Look for a bent tube, damaged footpad, loose mounting, pinched harness, packed mud or a pad that sank into soft soil. Compare the jack with the opposite side. A visibly bent or leaking jack should not be forced through another automatic cycle.

Check battery support before retesting

Ground Control is a high-current 12V system. Lippert’s same error chart lists Low Voltage when battery voltage drops below 10.8V DC. Charge the house battery correctly, inspect main connections and watch voltage under load before blaming the controller.

Low voltage is a separate displayed error, but poor power can contribute to abnormal motor current and uneven jack behavior.

Why the RV may level on one site but not another

Jack travel is measured from the suspension and frame position at that campsite. A shallow depression under one landing foot, soft soil or a slightly different trailer attitude can consume several inches of travel. If the error follows one physical corner on multiple reasonable sites, that is stronger evidence of a jack, mount or wiring problem than site slope alone.

Clear the message only after correction

Lippert directs the cause to be corrected before pressing Enter to clear an error. If the condition remains, the message returns. Run Auto Level again only after the site, jack disposition and power supply are acceptable.

Difficulty and service boundary

  • Owner checks: site slope, jack extension, footing, visible damage and battery support.
  • Owner action: controlled retraction and relocation using the exact manual.
  • Service work: a jack that stalls, bends, leaks, will not retract or repeatedly reaches the limit on reasonable ground.
  • Best evidence: affected corner, stroke position, ground condition and voltage during movement.

Frequently asked questions

What does Out of Stroke mean on Lippert Ground Control?

It means a jack reached maximum travel before completing the lift, or the controller detected an unexpected high-current stall.

Can I clear Out of Stroke and press Auto Level again?

Correct the site, jack disposition, footing or damage first. Lippert says to repair or otherwise correct the issue before pressing Enter to clear it.

Will leveling blocks prevent an Out of Stroke error?

Stable, properly rated pads can reduce required jack travel when allowed by the RV instructions, but the safest correction for excessive slope is often relocating the RV.
