I stumbled on one of these at Goodwill the other day.  It looked like it may have been used once, and the price tag was only $40, so I had to take a chance on it.  I took it home, plugged it in, and set the temp and time on it, but it would never get hot.

Anybody else use one of these and may be able to tell me what's going on?  I'm hoping it's an easy and cheap fix, because I'd like to keep it.  I've only got 7 days to take it back to the Goodwill store, though.
