Lippert RV Leveling System: Easy Setup Guide -

Introduction

A Lippert RV leveling system helps many U.S. RV owners level a fifth wheel, travel trailer, or motorhome at a campground, driveway, or seasonal site. The system may use electric jacks, hydraulic jacks, or both. A control panel or app commands the jacks to raise and lower the RV.

The basic process is simple: park on a firm site, secure the RV, extend the correct jacks, and confirm that the RV is stable. The exact steps depend on the Lippert system installed, such as Ground Control, Ground Control 3.0, Ground Control 4.0, Level Up, or OneControl.

This guide explains how Lippert leveling systems work, how to use them safely, and how to find common faults without guessing or replacing parts too soon.

What Is a Lippert RV Leveling System?

A Lippert RV leveling system is a powered jack system that helps reduce side-to-side and front-to-back tilt after you park. Lippert Components, Inc. is also known as LCI. Its systems are widely used on fifth wheels, travel trailers, and motorhomes sold in the United States.

A typical system has these parts:

Front landing gear: Supports the front of a fifth wheel.
Rear leveling or stabilizer jacks: Support the rear part of the RV.
Controller: Reads commands and controls the jack motors or hydraulic valves.
Touchpad or control panel: Lets you select manual or automatic operation.
Electric motors or hydraulic pump: Creates the force that moves the jacks.
Position sensors: Help the controller track jack movement on some systems.
Wiring, fuses, breakers, and grounds: Supply power and control signals.
Optional OneControl app or remote: Provides wireless control on compatible setups.

Leveling is not the same as stabilizing

Leveling changes the RV’s position so the floor, appliances, and living space sit more evenly. Stabilizing reduces movement after the RV is parked.

The jacks are not a substitute for:

Wheel chocks
A parking brake
A properly rated hitch or pin connection
Jack stands for repair work
A stable parking surface

Do not use the leveling jacks to lift the RV high enough to work beneath it. The jacks can move, lose pressure, or fail. Use equipment rated for the RV’s weight and follow the chassis or vehicle manufacturer’s service instructions.

Electric versus hydraulic Lippert systems

System type	How it moves	Common benefit	Common concern
Electric	Individual motors turn screw-driven jacks	Simple control and no hydraulic fluid	Motor, gear, wiring, or ground faults
Hydraulic	A pump sends fluid to cylinders	High lifting force and fast movement on some RVs	Fluid leaks, valves, pump, and battery issues
Hybrid	Uses more than one jack or drive type	Fits certain RV layouts	Diagnosis varies by component

The model name matters. A Ground Control electric system does not use the same service steps as a Level Up hydraulic system. Find the model number before ordering a motor, controller, fuse, remote, or replacement jack.

Before You Use the Leveling System

Prepare the RV before pressing Auto Level. Most leveling problems begin with poor site selection, weak power, an unsecured RV, or a control panel that does not know the correct zero point.

1. Pick a firm, suitable site

Choose a site that is as level as practical. Avoid soft shoulders, deep gravel, unstable soil, broken pavement, and areas where water may collect.

Place blocks or pads under the jacks if the owner’s manual allows them. A wider, solid pad can reduce sinking on soft ground. Do not use loose objects that can crack, slide, or collapse.

2. Keep the RV connected as required

For a fifth wheel, keep the tow vehicle connected until the front landing gear is down and the hitch is properly released. Some systems use the front landing gear during unhitching. Follow the RV manufacturer’s hitch procedure.

For a travel trailer, keep the trailer attached until the trailer is secured with the parking brake, wheel chocks, and the correct tongue support procedure.

3. Chock the wheels

Chock the wheels on both sides before you disconnect from the tow vehicle. Chocks must contact the tires firmly. Do not rely on the powered jacks to stop the RV from rolling.

4. Check battery power

A weak house battery can cause:

Slow jack movement
Clicking motors
Controller resets
An error message
A system that works in one direction but not another

Many Lippert systems need stable 12-volt DC power. Shore power does not always correct a weak or damaged battery. Check the battery condition, terminals, main fuse, and ground connection.

5. Clear the jack path

Look beneath and around each jack. Remove rocks, cords, hoses, blocks, and other objects that could stop movement.

Keep people, pets, and body parts away from moving jacks. The system can create strong crushing forces.

How to Operate a Lippert RV Leveling System

The safest operation method is the one in the manual for your exact system. The sequence below describes the general process used by many Lippert installations.

Manual leveling and automatic leveling

Manual mode lets you control each jack or jack group. It is useful when:

The site has a steep slope.
One side needs a small correction.
The automatic system stops before the RV is level.
You need to retract a specific jack.
You are diagnosing a motor, sensor, or controller issue.

Automatic mode uses the controller’s programmed zero point. The system tries to return the RV to that position. Auto level is convenient, but it cannot remove every problem caused by a sloped or weak site.

General setup sequence

Park the RV. Set the parking brake or place the tow vehicle in park.
Chock the wheels.
Connect power as directed. Use the required battery and ignition settings for your model.
Disconnect or release the tow vehicle only after the RV is secured.
Turn on the Lippert control panel.
Check the display for error messages.
Select Auto Level or the manual controls.
Watch every jack while it moves.
Stop the process if a jack bends, slips, twists, or contacts an obstacle.
Check the RV after the system stops. Doors, floors, refrigerator position, and visible jack contact can reveal a problem.

Some systems begin with front landing gear, while others extend rear jacks or use a programmed sequence. Do not assume that two Lippert systems use the same order.

How to tell if the RV is level

Use a small bubble level on a solid interior surface or compare several surfaces. A refrigerator floor, countertop, or frame area may not perfectly match the ground.

Check both directions:

Side to side: Place the level across the RV.
Front to back: Place the level along the RV.

A level reading confirms position. It does not confirm that the RV is safe or stable. Inspect the tires, chocks, hitch, jacks, and ground after leveling.

Setting or resetting the zero point

The zero point is the position the controller treats as level. If the RV repeatedly stops with a visible tilt, the zero point may be wrong. A zero-point procedure normally requires manual adjustment until the RV is level, followed by a button sequence on the touchpad.

The exact button combination differs by Lippert model and controller version. Use the model-specific Lippert manual. Do not guess the sequence, because the wrong command may retract or extend the jacks.

Lippert RV Leveling System Troubleshooting

Start with simple, safe checks. Do not remove a jack, open a hydraulic line, or bypass a safety circuit while the RV is supported by the system.

The system has no power

Possible causes include:

Dead or weak house battery
Loose battery terminal
Blown fuse
Tripped circuit breaker
Poor frame ground
Damaged control-panel connection
Ignition or parking-brake condition not met

Check in this order:

Confirm battery voltage using the RV manufacturer’s recommended method.
Inspect the positive and negative battery connections.
Look for corrosion or a loose frame ground.
Check the labeled fuses and breakers.
Confirm that the required ignition, park, or brake condition is met.
Inspect visible wiring for cuts, crushed insulation, or loose plugs.

Do not replace a fuse with a larger fuse. If the replacement fails again, stop and find the short or overloaded circuit.

A jack moves slowly or only clicks

A clicking sound often points to low voltage, a poor connection, a motor problem, or excessive mechanical load. It does not prove that the motor is bad.

Check:

Battery condition
Battery and ground cables
Motor wiring
Jack alignment
Dirt or damage around the jack
Whether other jacks show the same symptom

If all jacks move slowly, suspect power or a system-wide connection first. If one jack is slow, suspect that jack, its motor, its wiring, or its mechanical load.

One jack does not move

A single inactive jack may have:

A failed motor
A loose connector
A damaged wire
A failed relay or controller output
A seized or damaged jack
A position-sensor fault on systems that use sensors

Do not repeatedly hold the switch while the motor only clicks. That can heat the motor and wiring.

Inspect the jack while a helper uses the control. Keep hands clear. If the motor runs but the jack does not move, the drive mechanism may be stripped, jammed, or disconnected.

The RV is not level after Auto Level

The most likely causes are:

Incorrect zero-point calibration
A site that exceeds the system’s practical range
A jack pad that sank
A jack that did not fully extend
A sensor, wiring, or controller fault
A change in load inside the RV

First, confirm that all jacks made firm contact. Then measure the RV in both directions. If the jacks appear to work normally, recalibrate the zero point using the correct manual.

Do not keep extending one jack to force the RV level on a soft or sloped site. A large correction can reduce stability or overload the jack.

The system shows an error code

Write down the exact code and the conditions when it appeared. Note whether the RV was connected to shore power, whether the battery was charged, and which jack was moving.

Then check the manual for the exact controller and system. An error code can point to:

Low voltage
A communication fault
A jack position problem
A motor or sensor issue
A timeout
An out-of-range condition

Avoid clearing the code before recording it. The code may help a service technician find an intermittent fault.

A hydraulic Lippert system leaks or will not retract

Hydraulic systems need extra caution. Look for fluid around:

Hoses
Fittings
Cylinders
The pump
The reservoir
Valve blocks

Do not place your fingers near a suspected hydraulic leak. Pressurized fluid can injure skin. Do not loosen a fitting to release pressure unless the service procedure specifically requires it and you have the proper training.

A low reservoir, air in the system, a failed pump, a stuck valve, or a damaged cylinder can prevent normal movement. A qualified RV technician should inspect a system that leaks, drops under load, or cannot retract after basic power checks.

Quick symptom table

Symptom	First checks	Stop and seek service when
No display or response	Battery, fuse, breaker, ground	Power returns and fails again
One jack is silent	Connector, motor wire, controller output	Wire is damaged or motor overheats
All jacks are slow	Battery voltage and main cables	Battery is good but voltage drops under load
RV stops out of level	Jack contact, site, zero point	A jack twists, sinks, or bends
Hydraulic fluid appears	Reservoir and visible leak location	Fluid sprays, a hose is damaged, or pressure remains
Jack will not retract	Obstruction, power, manual procedure	RV cannot be safely moved

Maintenance and Care

Routine checks can prevent many Lippert leveling failures. Perform them when the RV is parked safely and the jacks are not carrying an unsafe load.

Electric jack care

Inspect electric jacks for:

Bent tubes or mounting brackets
Damaged wiring
Loose bolts
Corrosion
Dirt around moving parts
Unusual noise
Uneven movement

Lubricate only where the model manual permits. Some components require a specific grease or lubricant. Extra lubricant can attract grit or reach electrical parts.

Hydraulic system care

For hydraulic systems:

Check the fluid level as directed.
Inspect hoses and fittings for leaks.
Look for wet areas around cylinders and the pump.
Keep the reservoir cap and surrounding area clean.
Use only the fluid type specified by Lippert or the RV manufacturer.

Do not mix fluids unless the service documentation allows it.

Battery and electrical care

A leveling system depends on sound power connections. At routine service intervals:

Clean corrosion from battery terminals.
Check cable tightness.
Inspect the main ground.
Look for rubbed or pinched wires.
Confirm that fuse ratings match the documentation.
Charge and test the battery before a long trip.

A battery can show a normal resting voltage and still fail under load. If the system slows sharply during operation, have the battery and charging system tested.

Storage

Before long-term storage:

Retract the jacks fully unless the manual says otherwise.
Clean dirt and moisture from exposed parts.
Protect the RV from water intrusion.
Disconnect power only as the RV manual recommends.
Keep the control panel and remote dry.
Inspect the jacks again before the next trip.

When to Repair, Replace, or Call an RV Technician

A small wiring repair may be reasonable for an owner who can safely identify the circuit and follow the wiring diagram. A jack replacement, hydraulic repair, controller diagnosis, or structural repair needs more care.

Call a qualified RV technician when:

A jack is bent or pulling away from its mount.
The RV shifts while supported.
Hydraulic fluid is leaking.
The system repeatedly blows fuses.
The controller shows a persistent fault.
The jack will not retract.
The RV cannot be moved safely.
The problem involves a frame, axle, hitch, or structural part.

Before buying parts, record:

RV year, make, and model
Fifth wheel, travel trailer, or motorhome type
Lippert system name
Controller or touchpad model
Jack label and part number
Error code
Photos of the jack, wiring, and controller
Whether the fault affects one jack or the whole system

The correct replacement part depends on the exact system and revision. A similar-looking motor or controller may not communicate correctly or may have a different gear ratio, connector, or mounting pattern.

Common Mistakes to Avoid

Using the jacks without wheel chocks

Jacks can support part of the RV, but they are not designed to prevent rolling. Chock first.

Raising the wheels off the ground

Most leveling systems are intended to level and stabilize the RV, not lift the tires clear of the surface. Follow the manual and keep the wheels supported unless the manufacturer provides a specific procedure.

Making large corrections on a bad site

A very uneven site can push the jacks near their travel limit. Choosing a better parking position is often safer than forcing the system to correct a major slope.

Ignoring the battery

A shore-power connection does not guarantee that the battery, cables, or ground can deliver the current the jacks need.

Calibrating on an unlevel surface

If you set the zero point while the RV is tilted, the automatic system may repeat that tilt each time.

Working beneath the RV

Never place your body beneath an RV supported only by powered leveling jacks. Use properly rated supports and follow safe service procedures.

Frequently Asked Questions

How do I reset a Lippert RV leveling system?

The reset method depends on the controller and system. Some procedures involve turning the panel off and on, while zero-point calibration uses a specific button sequence. Check the manual for the exact Lippert model before pressing a reset combination.

Can I manually level an RV with a Lippert system?

Usually, yes, if the control panel provides manual jack controls. Manual mode is useful for small corrections and troubleshooting. Move one jack or jack group at a time while watching the RV and keeping clear of pinch points.

Why does my Lippert leveling system say “out of stroke”?

The system may believe a jack has reached its travel limit, or a sensor may be reporting an incorrect position. A short site, poor jack contact, low voltage, wiring fault, or mechanical problem can also cause the message. Do not force the jack. Inspect the site and consult the model manual.

Can I use blocks under Lippert leveling jacks?

Many RV owners use solid jack pads or blocks to reduce the extension needed and limit sinking. Use only stable materials and follow the RV and Lippert instructions. Never use cracked, loose, or unstable objects.

How long should Lippert leveling jacks last?

There is no single service life for every Lippert jack. Life depends on load, weather, maintenance, storage, alignment, and use. Unusual noise, uneven travel, leaks, bent parts, and repeated faults matter more than age alone.

Can I drive with the Lippert jacks partly extended?

No. Retract the jacks fully and confirm the control panel shows the proper status before moving. Walk around the RV and inspect the clearance. A partly extended jack can strike the road or damage the system.

Key Takeaways

Identify the exact Lippert system before troubleshooting or buying parts.
Use wheel chocks and a firm site before operating the jacks.
Check battery power, grounds, fuses, and wiring before blaming the controller.
Leveling and stabilizing are related but different jobs.
Do not lift the RV for service with the leveling jacks alone.
Record error codes and inspect the affected jack before clearing faults.
Use the model-specific manual for zero-point calibration and hydraulic service.
Call an RV technician for bent jacks, hydraulic leaks, structural damage, persistent electrical faults, or unsafe movement.

Conclusion

A Lippert RV leveling system works best when the RV starts on a firm site with good battery power, secure wheel chocks, and the correct zero-point setting. Auto Level can save time, but it cannot replace site selection, inspection, or safe judgment.

If the system fails, begin with power and visual checks. Then separate a single-jack fault from a system-wide fault. Stop using the system if the RV shifts, a jack bends, a fuse keeps blowing, or hydraulic fluid leaks.

The next useful step is to find the Lippert system name and controller model, download the matching manual, and record any error code before attempting a repair.
