Ace 29.3 Slide Issue

The other day, after leveling my coach, I extended the slide. It made a funny sound like it was rubbing something but nothing was in the way. After fully extending and amping out, when I went to retract it and it only moved in a few inches and stopped. Actually, it sounded like the front motor stopped first. I extended it and re-synced the motors but again it only wanted to come in a few inches and stopped. I talked to my dealer (in vain) and then called Thor. Thor was very helpful, walking me through checking the control box located in the second storage bay. No error codes blinking etc. So he had me press the button 6 times with a ball point pen, then hold it on the seventh time until the lights blinked rapidly. After that, I was able to retract the slide without a problem. No funny noises either. We tried extending the slide again. Again, when retracting it stopped after a few inches. Again re-sync the slides but again the same results. Again, press the reset button six times then hold the seventh etc. Again it came right in. My dealer will not even look at it until the 10th of August and we are leaving on a trip on the 4th. Since we will only extend and retract the slide once on our trip we will go ahead and go.

Has anyone with a 29.3 experienced this? Thanks for your input.

Bob

Sounds slightly familiar. My front motor does stop like yours. I press Extend briefly to get slide moving out, pause, then retract all the way in.

That usually works for me. Kinda like swinging a bucket of water back to gather momentum forward.

This sounds early familiar, I had a Miramar 34.2 with the full wall slide. It was doing the same thing, also the front half would actually tip slightly while going in and coming out. The motors would also get out of sync and stop.

The dealer removed the slide completely and discovered during production, they forgot to install a roller in the forward part of the slide.

IMHO, I think all the moving in and out over time did some permanent damage to the slide without that roller in place. Other problems with the slide led me to that conclusion.

Are you noticing any damage to the slide tracks, chipping, gouges, flakes of metal on the floor near the slide motors? I would have your service center check to make sure all components on your slide are in place.

Good luck!

I moved our coach, and re-leveled it. I extended the slide with no issues. Upon examination, I noted the bottom front slide had a cut or gouge on the bottom track (gear) in the middle of the first cog. Almost like someone had cut it. I don't know if this is part of the problem or not. Also both the front and rear bottom track had a little discoloration on it (but not the top two) which could have been a little dirt or something. I was able to retract it this time without a problem. Go figure! Should I clean the discoloration off? What would you use?
