A few nights ago, the Wife and I were making brownies. After around 28 minutes, according to the timer, I went in to remove said brownies. Before I entered the kitchen, I smelled burnt brownies. Took them out, and checked the temp. Still showing 350*. All of a sudden, a continuous beeper went off, loud as hell. Readout on the stove showed "F-10". Checked the oven with my trusty infra-red t'meter, and it showed 550*. Within 2 more minutes, it climbed to over 666 degrees. Had the Wife call the FD, pronto. They show up 15 minutes later, and the oven finally shut off but the beeper kept screaming. They pulled it out, unplugged it, and said it had experienced thermal runaway. So that's what the F-10 warning was........... Anyone ever had the electrical board on their kitchen stove act this way?
