Auto-Leveling jacks not leveling

[jdarwin]

The auto leveling on our 3931fb is not working. It was working until I raised the middle and rear jacks to obtain more clearance. Now when I try to auto level, the front jacks completely raise up dropping the coach to the ground. The jacks keep trying to raise until it trips the breaker.

I called Lippert. They told me the batteries had insufficient voltage to operate the jacks. I pulled the batteries and tested the cells and they checked out. I then ran a load test using a battery tester and it checked out. I reinstalled them and the Lippert level up panel shows 12.6 VDC.

I can manually level the coach. It’s the auto leveling that’s not working. Any ideas what I should try next?

Maybe manul level it then recalibrate the system

Download the MyLCI app from Google play store. Lots of good info, TSB, manuals and troubleshooting are available on the app. Everything at your fingertips.

Maybe you can try to reset your board just unplug it from the back for 30 sec then plug back in see it that makes a difference.

The front of the trailer must be able to go below level during the auto level procedure. Example, if on a hill, nose high, the trailer must go nose low, below level, before rising up to level. This may or may not be your situation but good to know anyway.

There is a rear sensor behind the axles that plays in determining when the nose goes below level. It has caused these types of issues before.



But I would start ny disconnecting power to the front "brain", then manually level and re-calibrate. If the problem persists then consider replacing the rear sensor.

Do you have a ground control 3.0 LCI system?

I found the auto level part of the level up to be more trouble than its worth. It would sometimes just freak out. I have used it in manual mode ever since. I can do it faster and adjust the height to where I want it, not where it thinks it should be.

Jdarwin - just curious if you have swapped out the OEM 50 amp circuit breaker for an 80 amp breaker? (Just trying to collect all the info to assist the experts here advise you)

Patrickdoran - 3931FB has a hydraulic lift system.

never had a problem with the auto level. Remember auto level does not mean it will level the trailer no matter what. The trailer has to be sort of level to start with if not you will get a out of stroke msg. The nose of the trailer has to be higher than the rear of the trailer otherwise the nose will drop (kneel ) to the ground. There are limits to how far the legs will extend front to back and particularly side to side.

Diving to the ground is what mine was doing. However this is after taking it off my truck in my perfectly level pole building so I know the nose was higher

Try raising it up a bit more. You may have known it was level but the sensor at the rear of the camper did not.

I will give it one more try when I get it back home Monday.

On my 2012 Level Up system, the position of the nose has nothing to do with leveling. I park frequently in a spot where the rear of the RV is considerably higher than the front while still hooked up. So much so that it takes 18" of blocks under the front jacks to avoid an "out of stroke" condition. I raise the nose to get it off the truck, while still much lower than the rear, and hit "Autolevel". It works every time without fail. It is on such a slope that afterwards I can walk under the chin of the RV and I am 6' 2".

What won't work is hitting Left and Right at the same time to return the RV to the height when it was unhooked. For that to work, the nose had to be higher than the rear at "Autolevel" time.

I don't know if this will help but our Level Up was out of calibration and was un level even after going through the auto level procedure.

I manually leveled, turned the system off, and pressed the front button 10 times then the rear button 10 times which reset it. Works like a champ now.

A quote from LCI: Auto Level Sequence
1. Front landing gear retract, lowering the front of the unit below level, stopping, then lifting the front end to level the unit front to back.

Regardless of where the rear of the trailer is on a hill or otherwise, if the nose can't go below level, it won't auto level.

[Carl n Susan]

I agree the nose has to get below level to "Autolevel". What I was commenting was that the nose has to be higher than the rear when pushing the "Autolevel" in order to work.

Yes. It's the level up 3 system

[jdarwin]

Yes. It was replaced with a 100 amp breaker

Jdarwin, if you have the ground control 3.0 system, these are electric rams and not hydraulic rams. The 3.0 system is slower to operate than hydraulic revelers and has caused much grief to a lot of people. Are you sure you have electric levelers?

Thank you I mis-spoke. Our system is hydraulic. I’ve put anti-stiction fluid in the reservoir to stop the the popping noise.
