RV Leveling System Repair in Guntersville, Alabama
Jacks that won't extend, won't retract, or won't hold position make your RV unusable. We diagnose and repair all leveling system types — hydraulic, electric, and manual — across all major brands.
The System Has to Work Before You Can Use the RV
A leveling system that won't extend leaves you camping on a slope. One that won't retract leaves you stuck at the campsite. One that won't hold position means your RV is settling overnight and you wake up tilted. None of these are acceptable, and all of them are fixable.
The repair path depends on the system type. A hydraulic auto-leveler fails differently than an electric scissor jack system. A Lippert controller stores fault codes that tell us exactly where the failure is. An HWH system has its own diagnostic language. Guessing costs time and money — reading the system correctly doesn't.
We start with the controller, read what it knows, and trace the fault from there. That's how repairs get done right the first time.
Three Leveling System Types — One Shop That Handles All of Them
Hydraulic Auto-Leveling
A 12V pump moves hydraulic fluid through lines to cylinders at each jack. The system extends, levels, and retracts automatically based on commands from the controller. Common on Class A motorhomes and large fifth wheels.
Brands: HWH, Power Gear, Lippert/LCI, Spartan
Common failures: Pump motor failure, low fluid, leaking cylinders or lines, stuck solenoid valves, controller faults, level sensor failure.
Electric Scissor Jacks
Individual 12V motors at each jack drive a scissor mechanism that extends and retracts. Can be operated manually one jack at a time or automatically through a controller. Common on travel trailers and fifth wheels.
Brands: Lippert, Atwood, Venture, BAL
Common failures: Motor failure (often under retract load), control board fault, wiring corrosion, stripped scissor mechanism, switch failure.
Manual Stabilizers
Stabilizer jacks operated by hand crank or drill. They don't level the RV — they reduce movement once it's already level on the tires. Common on smaller travel trailers and as supplemental stabilization on larger units.
Brands: Lippert, BAL, Camco, Husky
Common failures: Stripped gears, seized threads from corrosion, broken welds, bent jack tubes from overextension or improper placement.
What Your Leveling System Is Telling You
These are the situations we see most often. If yours isn't listed, call us — the symptom description is the starting point for every diagnosis.
Jacks won't extend at all
Start with battery voltage — leveling systems draw heavy current and need a solid 12V supply. Check the fuse and any dedicated circuit breaker for the leveling system. If power is confirmed, the controller likely has a stored fault code. On Lippert systems, the keypad will display a code; on HWH, the system has indicator lights. The code tells us whether the problem is the pump, a jack, a sensor, or the board itself.
Jacks extend but won't retract
On electric scissor systems, retraction requires more force than extension — the motor is lifting the weight of the RV. A motor that worked going down may fail coming back up. On hydraulic systems, a jack that won't retract points to a stuck retract valve, pump pressure issues, or a controller that isn't sending the retract command to that jack. Tell us which jacks are affected — all four or specific corners narrows it immediately.
System levels but won't hold position
On hydraulic systems, jacks that slowly drift down indicate a leak — either at the cylinder seals, in the hydraulic lines, or at the solenoid valves that are supposed to hold pressure. This is a fluid-side problem. On electric systems, a jack that slowly retracts is usually a mechanical failure — a stripped thread or a motor brake that isn't holding. Either way, the RV is moving while you sleep, which is not acceptable.
One jack won't move, others work
On electric systems, a single non-moving jack points to that jack's motor or the wiring to it. On hydraulic systems, it points to the solenoid valve controlling that cylinder, or to the cylinder itself. The controller can often confirm this — a jack that the system sees as "not responding" shows up differently than one the system isn't even trying to move. We isolate the affected jack and work backward from there.
Error code on the controller display
Error codes are the system telling you exactly what it detected — low voltage, a jack that didn't reach its target, a sensor out of range, or a motor that drew too much current. The code is brand-specific: a Lippert code means something different than an HWH code. We read the code for your specific system, interpret it correctly, and use it as the actual starting point for diagnosis rather than clearing it and hoping the problem goes away.
System is slow or sluggish
On hydraulic systems, slow operation usually means low fluid, a pump that's losing efficiency, or a partially blocked filter. On electric systems, slow jacks often indicate a motor drawing more current than it should — a sign of wear or a mechanical bind in the scissor mechanism itself. Running a sluggish system hard accelerates the failure. Catch it early and the repair is a fluid top-off or a motor. Ignore it and it becomes a pump replacement or a mechanical rebuild.

Leveling System Questions We Hear Every Day
The most common causes are a low battery, a blown fuse, or a fault code stored in the leveling controller. Hydraulic systems also fail when the fluid level is low or the pump motor has failed. Electric scissor jack systems can fail at the motor, the switch, or the control board. The diagnosis starts with power — if the system has adequate 12V supply and the fuses are intact, the next step is reading the controller for fault codes, which tells us where in the system the failure actually is.
Hydraulic leveling systems use a 12V pump to push fluid through lines to hydraulic cylinders that extend and retract the jacks. They are common on Class A motorhomes and large fifth wheels and can support very heavy loads. Electric scissor jack systems use individual 12V motors at each jack to drive a scissor mechanism up and down. They are common on travel trailers and lighter fifth wheels. The repair path is completely different for each — hydraulic systems fail at the pump, lines, cylinders, and fluid level, while electric systems fail at the motors, control board, switches, and wiring.
On electric scissor jack systems, this usually indicates a motor that works under light load (extending) but fails under the heavier load of retracting against the weight of the RV. On hydraulic systems, a jack that extends but won't retract can indicate a stuck or failed retract valve, low fluid level, or a pump that can't build enough pressure for retraction. Describe which jacks are affected — all four or one corner — and we can narrow the diagnosis before you come in.
Yes. We service and repair Lippert (LCI), HWH, Power Gear, and all major RV leveling system brands. Each manufacturer uses different control boards, jack assemblies, and hydraulic components — the repair approach is specific to the brand and system generation. We stock common components for the most widely used systems and can source parts for older or less common units.
Error codes on RV leveling controllers indicate a fault the system detected — low voltage, a jack that didn't reach its target position, a sensor failure, or a motor that drew too much current. The code tells us which jack or which part of the system triggered the fault. We read the controller, interpret the code for your specific system brand, and use it as the starting point for diagnosis. Call us with the code displayed and we can often tell you what it means before you drive to the shop.
