I just remodeled the kitchen, moved the oven/range back in, plug it in and I get an F20 error. Nothing will work but the clock. I can use the controls and they seem to think that the oven turns on, but it doesn't get hot. Also, the burners won't turn on unless the oven is on (they don't actually turn on either, but the display will say they are on).

This is a Kenmore model 790.9912 3405 and is 18 months old. I've tried resetting the breaker, unplugging and replugging, I even took off the back panel and blew out dust with my compressor, hoping that would help. Is this f20 error something I can fix?

Noteworthy - I did use the oven self-cleaning feature about 2-3 weeks ago. After reading the horror that can wreak upon the electronics that'll be the last time!
