Started a brisket this morning. The element and light is staying on all the time and just wont get to temp. It is now at 220 after 2 hours. I see the rewiring threads but that is usually for a completly dead unit. Mine is just not getting hot all the way. Any ideas what the problem could be. I hope I can get the brisket to 165 then I will wrap it and put it in the oven to finish. I do have my et-732 to double check the temps. No wind and is 40degrees outside now. Never had an issue before.
