1 issue I've been having is the grill starts off fine, but will go out and check on it and the "actual temperature" is showing flashing dashes. The grill is set on 250 and the hopper is full and the temp on the hood says 100-110. Then I got it going again and kept the temp at 250 and the hood said 500 and when I opened it you could see the flames coming out. I'm at a loss. I messed with it for at least an hour and brought the meat inside and threw it in the oven. PLEASE HELP!
