We have 2 Schwentek slides on our unit that have worked flawlessly. My friend has the Pinnacle with the large kitchen/entertainment slide which has given him some trouble. Mostly not retracting without binding up occasionally. The tech supervisor came out to his home one day as he was getting ready to leave on a trip and the slide hung up. I went over to watch the tech fix the slide. He went right over to the wiring harness inside the unit on the floor in the corner of the slide. He pushed on the harness and moved it so it would not be pulled as the slide operated. He then pushed the retract button in and moved the slide in about 6 inches. Then he extended it until it was open fully and held the button a few seconds after the slide quit moving. He says this will recalibrate the motors. He could recreate the problem to prove his method. He said almost all of the problems are with the wiring harness connections. If the slide is just a little out of whack it will quit as the pressure sensors in the slide controller are very sensitive. This is designed so the slide protects itself from damage to the slide or if you leave something in the way of the slide it will not crush it. If you bind up the slide and can't get it out of the bind by pushing on the slide you can disconnect one of the motors at the control panel and jog the slide until it is straight and then plug in both motors. He says open and close the slides without stopping after the RV is level and be sure to hold the buttons a few seconds after the slide stops. If you notice the slide is out of sequence such as both sides of the slide are not fully extended you can bring the slide in 6 inches and extend it until it opens and the motors should synchronize.
