Grinding noise/slide won't extend

So, MH is literally days old and suddenly bedroom slide is making a horrible grinding noise and won't extend. Worked fine the whole trip. Checked for obstructions, both inside and out but it just won't go. Never had this happen in any of our other coaches. It's a concerning noise 😳

Nothing you can fix. Trip to dealer is your only option. IMO.

Bah humbug. Got some other things we discovered on the maiden voyage, so looks like we are headed to Denver. Oh well. At least it didn't get stuck in the out position.

Learned a trick today that might help others. We called our dealer, he asked if we had lost power recently (yes due to new garage we just built and faulty outlet). Told us, have someone hold slide out switch and someone else sort of rock the slide gently because the mechanism gets bound up in power failure (my crayon understanding is that it kind of "let's go" when the power goes out and sometimes doesn't properly rewind.). Probably a more proper term.
Anyway, it worked and since the next appt was July 31st..I'm pretty excited about it. I can try to explain that further if that didn't make sense, but in this case with a brand new coach there wasn't really any mechanical failure and with a recent power outage I thought this might work for someone else in the future

Is this a Swintek slide from Lippert? You can tell by the "railroad tracks top and bottom of the slide side panels.

I can look when it gets back from being dumped. Husband just took it down the street. It's whatever came on the 2015 Charleston 450BH. We didn't make changes in that area.

You can tell inside while the slides are "in" the tracs will be obvious on the inside. Mfgs change something every year, could be new to Charleston. What I'm getting at is the "tracs" are the 2nd component of a gear drive. If you operate the slide while a gear tooth is damaged you can make it worse. If its hydraulic, different comments apply.

If it is the bunk/wardrobe slide it is most likely the cable driven mechanism. I know that all Berkshire 390/400 bh's have a bunk slide that is cable driven. I hope that rocking the slide permanently fixes the problem but I had the motor/gear box in my bunk slide die shortly after getting my new coach. It was making the same horrible grinding noise that you described and it required that the motor/gear box be replaced. It is a bear of a job that is best left to the techs to replace.
Good luck.
Tom
