I have Thermador stainless double ovens. I am getting a failure code of F24. It beeps and will not operate anymore. I was able to turn off and on the breaker and it would reset, but problem is worsening. F24 states "touch input key stuck" and the recommended repair is "replace power delay board and touch panel". I have several questions: 1. is this one part or two parts that need to be replaced? 2. I have part # AP2836639 as a replacement part to order, is this correct?, and 3. I am not an electrician, but I am good at things like this, do you feel I can replace this part on my own? Thank you.
