It sounds like you have a Lippert Electric Leveling System like Item # LC358590. The "LF" error message indicates a problem at the left front jack, a ground or short, or perhaps a power issue like the battery stopping to send power. I would start by checking your ground wires and making sure that they are firmly secured on a clean, bare metal surface. Next, I would look to see if any wires are loose, pinched, or damaged. I would pay careful attention to any areas where corrosion, exposure, or damage could easily impact your wiring and your power jack system.

After you fix whatever is causing your error message, you will need to clear your error message. You will do this by:

Extending all jacks at least 6 inches. Then press and hold the retract button until the jacks begin retracting. All of the jacks should fully retract and clear the error.

If you have a 6-point system the middle jacks only operate in error mode. To engage the middle jacks you would need to press the left and right buttons simultaneously.

Check the manual for the system because some things have to be done in a certain order for the system to operate correctly. That should clear your error message and prevent future errors (unless there is an actual electrical or mechanical problem).

If all of the wiring looks good and you are still having this problem let me know and I can help you troubleshoot further. If you have any other questions, let me know.
