I have a 820 Pitt boss that is overheating. When i set the temp at 225, the heat continues up to 360 and higher. My pitt bosd is about 4 years old. Reading this post, a lot of you guys have the same problems. I spoke to a customer service tech and he informed that my digital temp panel is bad. Before I purchase a new one, can one of you pitt boss owners let me know if you agree with the tech.
