Frustrated since I am still dealing with the temp going way higher than it is set for and burning food. I did the temp testing over the phone with a tech but they tested at 350 and it went to 400 and they said this is within range so they couldn't send a tech. The issue is when it's set at 400 and goes to 550, but I'll have to do the over the phone temp testing all over again and I haven't had time for that so it's frutrating.
