I dehydrate herbs and have only done garlic slices for dried garlic, to save the crop. The bulbs were beginning to sprout and get discolored, so I saved what I could that way.
However, dehydrating garlic requires either a door to close off the kitchen or windows to open. The first day just burned our eyes out.

Or you could put your dehydrator outside for a day. We do this when we make onion powder.

Try setting the dehydrator in the garage for garlic.
Also, try roasting some before drying. It changes the flavor some. I think it tastes better that way, but try it and see.
