I just opened and set up my brand new Mini Advance. It heats up, fan works, all controls work, but it doesn't turn. I have the tray in correctly, and even tried watching it turn with the lid off. The gear on the end of the motor just does not turn. I've emailed Brinsea customer support, but was wondering if anyone has had similar issues or if I'm doing something stupid? Ive read the manual over and over and can't find anything in it or online.
