I'm a 56 yr. old female with disability in one of my hands but is was so easy due to instructions that I wish I had called ApplianceParts first but I will forever recommend them for every thing they supply parts for...After calling manufacturer and researching web for days I changed the thermostat as was told by troubleshooting info from another repair forum instructed it was a fairly cheap part so I thought it was worth a try but no dice still the same thing. I went back to web and found ApplianceParts and called the person on the phone told me with knowledge that only two things control the problem I was having. The thermostat was the first thing and control board the second thing I ordered part and 30 minutes later my oven was working again.
