It is likely that the interior gears have stripped when the jack over-extended.

If you have the manual crank that should have came with the jack, use it by removing the rubber plug at the top of the jack, insert the crank and fit it to the override nut. Turn handle counter-clockwise to lower the trailer.

If you no longer have the crank, we sell a replacement as part # JCH-1.

If manually cranking the jack is unsuccessful, you will probably need to replace the jack, as the jack manufacturers will smash or otherwise distort the end of the screw that turns to move the leg up and down to prevent it from over-extending. If it does end up extending too far the threads will become permanently cross-threaded and it will never work right again. We offer a replacement, part # LC285318.

I have seen references in various RV forums that mention that some of the Lippert LCI181794 jacks were built with a faulty clutch. If your camper is still under warranty, you might be able to get Flagstaff to replace it. If not, contact Lippert directly at 574-535-1125. I've seen several cases where Lippert replaced the jack immediately if it was one of the faulty ones.
