We have the same issue on our 2014...IK (island kitchen) model.
It happens even when hooked up to the TV, so it's *NOT* a low battery situation. We tap it with a wrench and it takes off, then bogs down again. DH has taken it apart, checked all the connections...everything seems fine...no corrosion on the connectors, etc.
It's sitting out back with a support under the tongue, for fear it'll fail and drop the trailer.
....until we schedule a return to the dealer. I have *no* idea what brand jack we have, can't find a make or model on it anywhere.
In the meantime it sits there with a bucket over it and a huge cedar stump under the tongue.
I think we want to replace it with a Barker...even if they won't pay for it.
