I have a Newmar, had a slideout motor problem (dif than your problem), took it to a Newmar dealer in central FL - now works like a charm. Newmar did mention that their slides operate different than other manufacturers, and to make sure that the repair was done either by a Newmar service center or a tech that had experience with Newmar slides. That was over a year ago, and the slide has worked flawless - I am a fulltimer, so it gets lots of use.
