Howdy all, I have a Landman smokey mountain series electric smoker. Smoking some ribs today and when I turned on the smoker for the preheat it beeps at me and displays "err2." I have smoked on the unit about eight times since getting it new for Christmas this last year. This is the first problem I have had. The unit seems to heat fine, but the beeping is driving me to drink Can't find my manual and I will call support on a business day, but was curious if anyone has seen this error before?
