My LCI leveling system was working fine earlier this year. In fact I got home from a trip and went to level and discovered the motor was burnt out (pn 414850 ). I did not want to spend $1,000 for an $80 motor from Lippert so I rebuilt the motor. Motor works great now but jacks don"t move when the system operates.

I could really use a hydraulic diagram to aid me in troubleshooting. Not the simple line diagram as found in the Lippert manual but an actual hydraulic diagram showing how the pump/jack valves/return valve/ are piped within the system. Anyone know where I might find this?

In the LCI manual it describes manually retracting the jacks. Manual opening the left/right or front/back pair of solenoids and then running the motor with an electric drill in the COUNTER CLOCKWISE direction. Question: when the system is in normal operation from the controls, does the pump motor run in a CLOCKWISE direction? I ask this as my rebuild may have resulted in the motor operating in the other direction.

First, if you are scheduled to check out that day, you should notify the campground office of your issue. Most RV parks are mindful of these kinds of issues and will be willing to work with you on scheduling. In the meantime, you should take these 5 steps to troubleshoot your RV hydraulic leveling jacks so that you can get back on the road.

Walk around the RV and put eyes on each of the jacks to determine if there are any obvious issues preventing you from getting the jacks retracted. Look closely to see if there is any hydraulic fluid leaking anywhere as well. If the temperatures are below freezing, you can pour some warm water on the base of the jacks to make sure they aren’t frozen to the ground. If you still can’t figure out what’s causing the problem, move on to the next step.

If you’re in a time crunch and need to vacate a site, you may have to explore temporary fixes. Your owner’s manual can also walk you through the manual retract process for your jacks. We used our manual to learn how to manually retract our jacks when our fuse blew once. Since each system, such as HWH, Lippert, and Quadra Bigfoot, has its own specific procedures, it is important to refer to the manual for your particular system.

Most hydraulic leveling jacks found on RVs today are HWH systems. These systems typically have a manual override that will allow you to retract the jacks in order to get your rig to a repair shop. This usually involves opening the manual release valve and then manually prying the jacks up.

If you’ve made it this far and still can’t get things fixed, know when to call for help. This could be as simple as asking around the campground and finding someone more familiar with the hydraulic jacks who can assist. Almost all manufacturers have a direct customer support line and some will be able to walk you through a fix over the phone.

Following these steps for troubleshooting your hydraulic jacks should make things a little easier for you when problems arise. Even if you are unable to fix the root problem yourself, you should be able to do enough to get moving and have a professional take a look at things.
