It happened to me on BOTH of our slides on a 3800... both times ours was the gearbox being made of CHEAP cast aluminum and the steel shaft would break the cup it sits in INSIDE the gearbox! And in turn it breaks one or multiple teeth off the gears. The gearbox is about $100.00 and if you are mechanical then you could do it yourself. If you have your slide in or out you can just simple have someone push/pull the slide in or out while holding the button. We have done that on 2 separate trips while waiting for the gearbox to ship. I will go out and take a picture of the part number. If you can see over the slide top on the inside near the center of the slide, you will see the gearbox and electric motor. It only takes a 1/2” and 9/16” wrench, one Allen wrench and monkeying around with the cables to adjust them right and some patience!!!
