Need some advice on the faulty performance of the controller of my BLUE BLAZING series ANALOG ELECTRIC VERTICAL SMOKER (3-SERIES). Wife bought it approximately 13 months ago on Amazon and it hasn't worked correctly yet. It's my first electric smoker and first Pit Boss product. So far I'm not satisfied. We bought it in April of last year and I started contacting Pit Boss customer service in May and have gotten the run around since. Any advice would be appreciated.
