Had this happen on a used POS 22 Phoenix Cruiser I bought between my Newmars. Those schwintek slides are horrible. It ripped the face off of the cabinets.
It took me a number of tries to reprogram the slides until I got it working right. Once the stops were set, I rebuilt the cabinets and got rid of the pos.
As for PC, they make claims about real wood cabinets and such, a complete lie in that coach. The slide had huge openings in the slide floor under the cabinets for wiring etc, with a rubber flap that did absolutely nothing. Might as well put a sign advertising "vermin hotel"
