Whirlpool Gold Oven Error code E6 F2

I have a WhirlpoolGold double electric wall oven(upper Convection) stainless/ black. Model#Model GBD307PDS09 Ser#XR2500422. I purchased it new in June of 2004. The oven has started to show error code E6 F2. I reset the clock function and the code goes away, the clock works and everything seems fine for about 1-2 days. Then the error code appears again and I reset the clock again and so on. The oven also seems to be working fine for right now. With Christmas coming I don’t want the oven to stop working in the middle of me cooking Christmas dinner. From what I have read in the threads, I didn’t see this condition or is my oven just starting the problem and it will eventually stop working like the others. I am trying to do this myself and may need some beginner instructions and what part numbers to order and how to expose the parts I need to replace. Please help !!
