Hey guys i have the tailgator pitboss and if i go from 350 to 200 or even 250 the grill will go into shut down mode and will quit working. It does this from time to time, not all the time, most of the time it will work fine . i usually unplug it and wait a bit then plug back in and it is fine. Also the other day i was cooking pizza on it at 300 and the whole grill was a ball of flames. Good thing i was watching it to put it out. Is my problem the control board?
