So you start hearing this obnoxious beeping sound coming from the underbelly of your rig. Ugh, there goes the peace and quiet! As an experienced RVer, I totally feel your pain. Those random beeps from the leveling system can drive you bonkers if you don’t get to the bottom of what’s causing them.
Let me walk you through some of the most common culprits I’ve encountered over the years that can set off the leveling system alarm. With any luck, we can get that beeping stopped and let you get back to the blissful sounds of nature!
Checking The Control Panel Error Code
The first thing you’ll want to check when the beeping starts is your leveling system control panel. Most systems will show an error code that gives you a hint about what’s triggering the alarm.
On my Lippert Level-Up system, for example, a flashing “E1” code indicates there’s a fault with the front left leveling jack. An “E2” points to the front right jack, and so on. Some systems use red flashing lights instead of codes, but the idea is the same.
So take a peek at those error messages and see if they steer you towards one corner of the RV. That can really narrow down where the issue lies.
If you don’t see any error indicators, the problem could be more general, like low hydraulic fluid or a wiring problem. But we’ll get to those later. Start with the basics first!
Inspecting The Leveling Jacks
Assuming the control panel gave you a hint, the next step is to head outside and take a look at the problem leveling jack. These hydraulic jacks are pretty rugged, but they can still get damaged over time.
Check the jack visually for any loose, bent, or damaged components. Anything look cracked or leaking fluid? How about the plastic housing around the cylinder – any major scuffs or punctures?
Give the pad a firm push to see if the jack still feels solidly in place. Tap on the hydraulic cylinder with a wrench to check for dents or flat spots.
If you find obvious signs of damage, the jack may need to be replaced. Your friendly RV service tech can help confirm if that’s the root cause.
While you’re down there, also check that the jack is fully retracted against the underside of the RV. Most leveling systems beep as a warning if a jack is still extended when you try to drive away.
Testing For Hydraulic Fluid Leaks
Another common source of trouble is leaks in the hydraulic system. The leveling jacks run off the same fluid reservoir that operates your RV slides.
So there could be a leak somewhere in the lines that’s triggering the low fluid sensor. Watch closely for any dripping hydraulic fluid around the jacks or slide mechanism.
Also look for signs of fluid spray or staining on the underbelly or chassis. A spray pattern usually points to a pinhole leak in the hydraulic lines or fittings.
If you spot a leak, you may need to get an RV technician to inspect and replace the faulty component. But at least you’ve identified the problem!
Checking The Wiring Connections
We’re still ignoring those annoying beeps…so let’s keep working down the list.
Issues with the wiring to the leveling system can also set off false alarms. The level sensor relies on clean power to operate properly.
First, locate the main control module for the leveling system, typically mounted in a compartment or the basement storage area. Unplug the connector and check for any corrosion on the pins and sockets. Spray with electrical contact cleaner if needed.
Also inspect any visible wiring running from the module to the jacks. Make sure the lines are clean, intact, and securely plugged in. Loose or damaged wires anywhere in the path can lead to electrical gremlins.
While you’re down there, check for signs of mice or other critters. Chewed up wires are no fun to track down!
Adding Hydraulic Fluid If Needed
Another simple thing to check – when was the last time you added hydraulic fluid?
The reservoir may just be running low if the jacks have seen a lot of use recently. Look for the fill port (often near the RV steps) and top it off with approved hydraulic fluid. This may get those jacks happily lifting again!
Follow the manufacturer’s guidelines closely, since not all hydraulic fluids are created equal. And take care not to spill, since hydraulic fluid can damage RV surfaces.
Adding fluid may just quiet those beeps for a while, so also have your dealer inspect for any leaks during your next service visit. Prevention is the best medicine!
Testing The Level Sensor
If we’ve struck out so far, the cause may be a faulty level sensor reading. These sensors measure the orientation of the RV and tell the system to adjust the jacks accordingly.
But like any electrical component, sensors can fail over time. Dirt, moisture, or power spikes can all knock them out of whack and create “false alarms” of incorrect leveling.
Try resetting the control panel to see if it recalibrates the sensors. Or you may need to reference the troubleshooting tips from your RV manufacturer or leveling system company.
For my Lippert system, they describe how to enter a diagnostic mode that shows the raw sensor data on the control panel. Pretty neat trick to see if the numbers are way off.
If a sensor seems flaky, replacement may ultimately be needed. But try simpler fixes first, like cleaning connections or checking for loose wires.
Watching For Problems During Operation
The next time you run the leveling cycle, keep an eye out for any odd behavior that points to trouble.
Do the jacks lower and extend fully, without hesitating or stopping? Any strange noises like grinding gears or squeaking?
How about when operating the jacks individually? Do they all seem to respond properly to the remote?
If one jack acts sluggish or makes odd noise, it could indicate a cylinder issue. Or it could point to wiring problems on that circuit causing power fluctuations.
Really observe what’s happening as the system runs. The sequence of events can provide helpful clues to get the root cause zeroed in.
When All Else Fails, Call For Service
Well, we’ve gone through my whole bag of DIY tricks and that blasted beeping is still driving us nuts. No more aimlessly tinkering – it’s time to tag in the pros!
Most RV dealerships have technicians and mechanics who specialize in leveling systems and can troubleshoot even squirrely electrical gremlins.
They have access to diagnostic tools and software to identify issues that we can’t detect as homeowners. And they can safely replace parts like sensors and hydraulic cylinders. So when in doubt, just pick up the phone and make an appointment to get those annoying beeps banished once and for all. Your sanity is worth the peace of mind!
Summary
- Check the control panel for any error codes to identify the problem jack.
- Visually inspect jacks for damage and make sure they are fully retracted.
- Look for hydraulic fluid leaks in the lines or fittings.
- Inspect wiring connections for corrosion and damage.
- Consider adding hydraulic fluid if levels are low.
- Test or reset the leveling sensors which may be malfunctioning.
- Observe the jacks during operation for abnormal behavior.
- Call a professional RV technician if needed for diagnosis and repair.
