I've had an 820 model for about a year and use it 1 or 2 times a month. I want to love this grill, but I've had to replace my controller twice already and now the 3rd one had died on me. I submitted a case 3 weeks ago, with a follow-up two weeks ago and now a 3rd one today, with NO response. I've also called their tech support 3 times and, after being on hold for an average of 1 hour and 10 minutes each time, I was ultimately disconnected. Is anyone else having a problem with this?
