Your bedroom slide setup, I think, is exactly like ours. Our slide moves a king size bed out the street side of the coach. We have had two "experiences" with our bedroom slide. I will try to explain what we did.
1st experience (Nov 2015): We parked in a RV park in North Houston, the Forest Retreat RV Resort. We were preparing the RV for the night when the bedroom slide would not move out. It was dead as a doornail! After our friend, AL, and I tinkered with it the next day for an hour, he called his son who worked on airliners for United Airlines at Bush International Airport. Before Al's son arrived, Al and I had the bottom half of the bed propped up to allow entry under the bed enough to reach the motor, drive sprockets, chain, and wiring. I explained to Al's son how it worked. He started by checking for power at the wall switch. The power was good in both the IN and OUT positions at the switch. Next he checked for power at the wiring under the bed going to the motor. The power was good. He next gave the wires attached to the motor an easy tug. One of the wires came off the motor! He securely hooked it back to the motor and the bed worked again as it always had. While there, Al's son "redid" the wiring and connections to better than new. He also adjusted the IN and OUT stops. He found the problem, fixed it, adjusted the stops, and "redid" the wiring in about 20 minutes!
2nd experience (Summer 2024): More recently and for a couple of years, as the bedroom slide moved IN and OUT, it would POP and momentarily, for about 1/2 second, stop moving. It would do that several times each time we moved the slide. If the coach was parked with a tilt to the left or right, then the slide when moving downhill would move with fewer POPS and momentary stops. But if the slide was moving uphill, then it would POP and momentarily stop every few seconds. It sounded like the drive chain was jumping over the sprocket teeth. Because a slide will move much easier downhill, there would be less strain on the drive chain. And vice versa moving the slide uphill. Does that make sense? It made sense to me. lol Having raised the bed several times to inspect what might be POPPING, I noticed the axle coming out of the chain drive mechanism attached to the motor was crooked. By crooked, I mean it was not a 90 degree angle. On the end of that axle is the drive sprocket for the chain. The drive sprocket and receiving sprocket are only a few inches apart, so the chain going around the two sprockets is only 15 to 20 inches long, I guess. So, anyways... I had a repair shop change out the drive motor and drive sprocket (all come as one piece, I think), and the slide moves perfectly again!
Hope this helps some...
