Howdy! i have had a 40" Masterbuilt Electric Smoker for about 4 months. Used it the other day to smoke some yard bird. When I went to open the unit to take the meat out, I felt like I touched an electric fence. Where ever I touched it, I got shocked. No water near the unit. Cord wasn't in water. Any clues? I am waiting for a call back from customer service at masterbuilt.
