I am getting an error message that blinks F30 EVERYTIME i click bake, broil or anything related to oven, I get nothing when i click clock, meaning i cannot program my clock on the stove at all. I opened the back and found an orange wire that has one side attached to purple wire near the fan. this orange wire has a small hard plastic piece right in the center which was broken-Burned.

I am not sure if that is the problem or how to order this part since I cannot see any electrical wire picture for me to pick the right part to order or know if this is the problem at all. I went to a local appliance store and bought wires for replacement, but did not had the black piece in the center. i am not sure if that is a temperature signal control or what. I really need this stove repair. PLEASE HELP....
