My jack will not retract and I need to leave tomorrow. What are my options?

Most systems have a documented manual retraction method intended for exactly this situation, and it is in your owner documentation. What matters is that it is a way to make the coach movable, not a repair — the fault is still present and the system should be looked at before you rely on it again. If the manual method meets resistance, stop; forcing it can damage the cylinder or the mount.

Is it safe to sleep in the RV with a jack that is leaking?

Sleeping in it is generally not the risk; going underneath it is. A leaking jack can lose support gradually, so the coach may settle unevenly, which is uncomfortable and can stress the frame but is not usually sudden. The absolute rule is that nobody goes under the coach, and that it is not left on jacks alone if it can be lowered onto its wheels.

Why does auto-level keep failing on this site but works everywhere else?

Usually the ground. Soft or uneven surfaces let one or more feet sink as the system tries to level, so the controller never reaches a stable solution and eventually errors out. Pads spread the load and frequently resolve it. A system that fails everywhere is a system fault; one that fails here is usually the site.

Should I top up the hydraulic fluid myself?

Better not to, because the correct level depends on jack position and it is easy to overfill. An overfilled system pushes fluid out when the jacks retract, which looks like a new leak and makes the next diagnosis harder. Note the level and any fluid you have found, and let it be set properly.

Repair guide

RV leveling and jack repair

Whether the coach is safe to move, and whether this is hydraulic, electrical, or control.

The immobility question and the load-bearing hazard. This is the only system here where the failure can make the RV impossible to move and where investigating it wrongly can drop the coach on someone. The content is organised around safety and mobility rather than around repair.

Stop-work system

Leveling jacks hold the coach’s weight. Never go under an RV supported only by its jacks, and never troubleshoot a jack under load.

Nothing on this page is a repair instruction for this system. What follows is what to observe and record so a technician can work efficiently — the work itself is theirs.

What brings owners here

The auto-level system reports an error and will not complete
One jack will not retract and the coach cannot be moved
A jack drifts down on its own overnight
There is hydraulic fluid on the ground under a jack
The system runs but the coach never reaches level

What to observe and write down

These are observations, not repairs. Each one narrows the problem before anybody charges you for time.

01
Never get under a coach supported by its jacks or stabilizers
Levelling jacks hold the coach’s weight and are not designed as, and must never be used as, a substitute for stands. A hydraulic fault, a failed seal or an accidental control input can drop the coach without warning. Nothing on this page is worth doing from underneath.
02
Record the exact error code from the control panel
Auto-level controllers report specific faults, and the code identifies which jack or which sensor is complaining. Photograph the display. This is the most direct information available about the fault.
03
Note the ground surface and whether pads were used
Soft ground, gravel, and hot asphalt let jacks sink unevenly, which the controller reads as a levelling failure that never resolves. Whether pads were under the feet, and what the surface was, is genuinely diagnostic.
04
Check battery voltage before assuming hydraulic failure
Levelling pumps and electric jack motors are heavy DC loads. Insufficient voltage produces slow, incomplete, or aborted cycles that look exactly like a failing pump. Note the voltage and whether the coach is on shore power.
05
Look for fluid, but do not top up blind
Note any fluid on the ground and which jack it is under. Hydraulic reservoirs are checked at a specific jack position — usually fully retracted — and adding fluid at the wrong position overfills the system and causes an overflow later. Report what you see and let a technician set the level.

How a technician works through it

Knowing the order matters: it tells you whether a quote skipped a step, and it tells you what a technician still has to establish before anyone can say what is wrong.

01
Establish whether the coach can be safely moved
Mobility is determined first, because it decides whether a shop is even an option and whether the RV must be made safe where it stands.
02
Read the controller and identify the reported jack or sensor
The system knows which leg or sensor it is unhappy with. Starting from the reported fault avoids testing the entire system to find something it already named.
03
Verify DC supply under pump load
Voltage is measured while the pump is running. This is a frequent root cause and eliminating it early prevents an unnecessary hydraulic diagnosis.
04
Separate hydraulic from electrical from control
A jack that will not move can be a solenoid, a valve, the pump, a motor, or the controller. These are distinguished by testing at the component rather than by symptom, because the symptom is identical across all of them.

What drives the cost

We publish no dollar figures anywhere on this site, because real prices vary by market, season, and technician, and a number we invented would look authoritative and help nobody. What is stable is what moves the number.

Whether the system is hydraulic or electric, which are substantially different in parts and labour
Whether a single jack, the pump assembly, or the controller is at fault
Whether the coach must be safely supported to work on a jack, which adds equipment and time
Seal and cylinder work versus solenoid and valve work, which differ considerably
Whether the fault has damaged anything structurally at the mounting point

Before you weigh any of that, settle who is paying. Warranty, insurance, or you works through the order that protects a claim — because authorising a repair before you have the answer is what turns a covered failure into one you funded.

Mobile or shop?

Diagnosis, solenoids, valves, sensors, controller faults, motors and fluid service are normal mobile work, and mobile is often the only option because a coach with a stuck jack cannot be driven to a shop. Cylinder rebuilds and mounting-point structural repairs may need shop facilities.

Next step

Work through structured triage for this system and you will end up with a written service brief: what you observed, in what order, and what has not been established yet. It is the document that lets a technician quote properly instead of guessing on arrival.

Being straight about what this is. No technician is signed to any territory yet — not one. We do not match you, dispatch anyone, or promise a call. What you get is the brief, and a request form that copies it to us so we know the demand is real. If you need someone today, take the brief and send it to a local technician directly; it works just as well that way.
