Several years ago, we had our front A/C running, and all of a sudden it started vibrating like crazy and we quickly turned it off. I went up on top, removed the shroud and couldn't see anything wrong. Had the DW turn it on while I watched and it started vibrating. I finally figured out that the inside blower fan had broken, and when not spinning, it looked fine. Once it started spinning, it would get distorted and was rubbing on the housing. I was finally able to get the correct fan from Dyers, and that fixed the problem. Of course, this wasn't a low profile unit, but it will still have the same type parts. I do remember taking a small cable tie and securing the fan together where the break was and got it working until the new fan arrived. If you are still in Las Vegas, Desert Mobile RV Repair is the one we had do a couple repairs several years ago, excellent guys. 702-379-7966
