RV Leveling Jack Won’t Extend: Troubleshooting Tips And Tricks

Nothing beats the sinking feeling that you have in your stomach when you press the button to extend your leveling jacks and nothing happens. That makes a bad start for what otherwise could have been a fun journey.

If the RVs jacks are stuck and won’t extend, you should try the following tips and tricks out to try and fix it.

1.Basic Tests

This step might seem pretty basic, but it can lead you in the right direction. There are some things that even you can easily spot. These will help with the troubleshooting process.

First, when you press the button, see if you hear anything. If you can’t hear any noise, it’s possible that it is a power-related issue. It might even be as simple as a blown fuse.

However, if you hear the jacks trying to lower but nothing is happening, it could be a more sophisticated mechanical issue.

After that, try to operate the jacks separately. Try to figure out whether the problem is with the whole system or whether it is the front jacks or rear jacks.

You might even find only one jack is having a problem. Once you’ve done some basic testing with the control panel, then it’s time to take a closer look.

2. Look Around

Try to watch each of the jacks to find if there are any obvious issues preventing the RV from getting the jacks extended.

First of all, look closely to see if any hydraulic fluid is leaking anywhere. Next, If the temperature is too low, you can pour warm water on the base of the jacks to make sure they aren’t frozen.

If you still can’t figure out what the problem is, move on to the next step.

3. Read the Owner’s Manual

The owner’s manual has detailed information about the uses of many parts of your Rv, including the jacks system. While you might have to read the manuals, which might seem a bit boring, but it might even tell you the solution.

The manual will give you the detailed troubleshooting steps that can try to find the problem. You will be able to use the observations of the tests that you did previously to find the cause of the problem.

The owner’s manual can also guide you through the manual extension process for your jacks.

4. Perform Manual extension

Most hydraulic leveling jacks on RVs are HWH leveling systems. These systems usually have a manual override. This will allow you to extend the jacks manually.

If you have to resort to this step, you must take all proper precautions to avoid injury. Never put yourself or anyone under the vehicle when attempting to manually extend the jacks without taking proper safety measures.

5. Check Fuses And Electrical Breakers

This is one of those things that can easily escape your mind. A fuse or breaker could burn out or trip. This stops power from going to the system that runs the leveling jacks.

If possible, watch the wires connecting the leveling jack system to the electrical panel. Sometimes wires can get loose and simply need to be reconnected. You can repair it with a wiring nut and electrician’s tape.

6. Ask for Help

If you’ve done all the steps and still can’t find the problem, it’s time to call for help. This could be as simple as asking around the neighbourhood and finding someone more experienced with the hydraulic jacks who can help.

There’s no shame in asking for help. You may even need to call a professional if things get too technical.
