Last month oven showed E2 F3 for any temp over 400. Checked resistance on both sensors every 50 degrees. Found issue with bottom sensor. Replaced it. Still got E2 F3. Replaced top sensor. Still getting E2 F3 for any temp above 400. Tech sheet states "replace control". Is this part number 4453608 on the diagram? Any other suggestions before I spend $$ would be appreciated.
Update: I removed the control unit (easy) and sent it to CoreCentric Solutions in IL. They repaired it in less than a week. I installed it and tested it to 475. So far so good. I will update if something changes.
