Vinnie we’ve had an American Harvest dehydrator for years and have been dehydrating everything from sweet potatoes - nice thin slices on a mandoline - to bags of Vidalia onions when the local Shriners sell them.
The only thing we didn’t have good luck with was bananas. I’d suggest if you are interested in trying again, start with something easy like thin apple slices or celery or onions.
When we first tried the dehydrator, we purchased this book and love it: http://www.amazon.com/The-Dehydrator-Bible-Includes-Recipes/dp/0778802132/ref=sr_1_1?ie=UTF8&qid=1390781843&sr=8-1&keywords=dehydrator+cookbook
Good luck with yours!
fwiw- Never dehydrate onions and garlic in the same room (closed up because it was winter), as the room storing cloth, or wools and silks for spinning. It took over 2 weeks of constantly changing out bowls of vinegar sitting all around the room to suck the stench from all the fibers.

Guess I’ll have to get up in the attic and dig it out.
