Thread: KitchenAid Superba KEMS307D8S6 Oven problem

I have a KitchenAid Superba built-in oven/convection oven/microwave.

I noticed that the oven doesn't cook completely so we installed a cooking thermometer to check the temperature. The following scenerio is what we found:

When the oven is set at a set temperature, let's say 400 degrees, it will beep when it has reached that temperature. At that time, our cooking thermometer says it is only 270 degrees. It can take almost 2 hours before that thermometer shows the temperature to be actually 400 degrees, resulting in undercooked food.

I tested to make sure the thermometer was reading right by setting the convection oven to 400 degrees. Within a few minutes both the convection oven and the thermometer show 400 degrees.

That would leave me to believe that something is wrong with the heating element on the oven side.

Occassionally the control panel will show an error code and after clearing it I will have to reset the clock. I have never written it down in the past, but last week I did and it shows what I believe to say "PF id=30"

I had a technician come out today and they don't know what the code means and they were showing readings of over 400 degrees in their tests like it would be burning my food instead of undercooking. I believe in this particular instance I have a faulty repairman and not an overcooking oven. However, since he was of no help I need to know what this code means and if it is related. He is wanting me to replace the main control panel and I don't want to just throw money at the problem. I want to fix it right. Any help would be greatly appreciated!
