Mine has started losing set point constantly. My last two cooks were only 1 and 2 hours long and I lost set point in both, and twice in the two hour cook. I also had a timer going in one and it was removed when the set point was lost. Most of the time I’ve had this happen the grill stays at the previous set temp, though I have been monitoring more regularly to make sure set temp back since I did have a time where it also stopped feeding pellets and grill went out completely before I caught it. No low temp warning. Right now I can’t trust my grill to do any longer cooks unless I’m able to constantly monitor it. I guess I need to call Weber as I submitted a ticket a couple weeks ago and haven’t heard back. Maybe was lost in the intertubes.
