Just got mine back...
My bedroom slide on a 25DS made a noise while extending. Thought that I better get it in since I was 90 miles from the house. It would not come back in. Called Service Dept and they said to hang tight and they would call the MFG in the morning and see what they thought. In the mean time they sent me the link to the repair manual.
In the morning they called and said to go outside and push it in, while the wife push the button. The gear box appeared to have a "Dental Problem", broken tooth on a gear. I was able to push it over the bad tooth and it thumped each time we hit the bad tooth. We got it all the way in.
I had removed the panel to expose the gearbox and motor assembly. I watched the assembly as my wife pushed the button. I could see the motor and it small, input shaft turning, but the output shaft was not turning the gear and chains.It all looked good except that the motor appeared to be installed with a slight tilt.
Dealer ordered the part and put it in last week. It appears that the tilt was causing the chain to bind on the gear which caused more of a load on the gearbox than it was designed for. It is now mounted nice and level and works great.
Troy at Freedom RV in Liberty Lake , WA has done a great job of fixing the little problems we have had.
