Whirlpool oven-microwave combo

I was cooking with my oven set to 300F and the oven switched itself over to the self cleaning cycle. I flipped off the breaker and left it off for 10 minutes and when I turned it back on, it began the self cleaning cycle again. Do I need to replace the microcomputer, or is it something else. The microcomputer is no longer available for this model, is ther another option?

Most likely the problem is a bad microcomputer. Probably it is time for a new oven.
