Anyone had their electric jack(s) fail?

Got home from a long car trip and went to check on the truck camper which we leave mounted on our truck. Anyway, one of the electric jacks was fully extended, actually overextended, and now won't retract manually or electrically. We have no idea how this occurred. Has this happened to anyone and do you have any advice on how to fix it? Can u imagine if this had happened going down the road?!

IM not that versed on jacks but there are different brands of elec. tc jacks . What jack do u have ?
I think one of them has a lever that allows the leg to drop down , free fall .

Maybe we can do a search on your brand and find a solution .

The jacks were up and the camper sitting on the truck. We have no idea what happened. Doubt it was a curious kid.......no one lives near us. Water intrusion? How would that make the jack extend? We're stumped and concerned......never even considered this was a possibility!

no but Ive had external switch stick. Water intrustion? Or curious kid? Is trucks weight on it?
I added cut off switches inside-so only power jacks when using.
