We love our FEC100, but we've been having some challenges lately. On at least 3 of the last 10 occasions, our smoker comes up to temp and runs well for a few hours but then suddenly dies. On each occasion we've had to use the reset switch to get power back on but I've lost hours of time and it's becoming quite concerning as we don't have the staff to be watching it every 30 mins. Has anyone else had this issue? I am wondering if maybe there's a firmware update I need? ....and if so how and where to get it? TIA!
