Well, lets see... To start.. I have the 790 model... the first thing that broke was the stoves door feel off... I mean it was not being used at the time (it was off) and the front " metal frame" fell open, then the glass slammed onto the floor. We where lucky as it did not break, so thank god it was not on at 450 then melted the floor. Got that fixed.

 Now, was cooking a Pizza... Took it out to check on it and turn... A loud pop and a spark came from the digital display and the whole thing went off.. HMMM

Called SEARS.. repair guy comes out.... tells me the board was fried "what ever that means"...
