I bought this dehydrator as a birthday gift for my husband. As soon as he plugged it in the motor blew up, literally. Nesco did send a replacement and the machine worked great for the next 3 sets of jerky dehydrations. Now, the motor will automatically shut off after about 15 minutes. I wonder if it is overheating and shutting off to protect itself. When working the jerky comes out great, but I have had way too many issues and am junking this machine and switching brands.
