Shut off the circuit breakers to the range for about 2 minutes to reset the microprocessor in the Range. Depending on what you were trying to set when the problem occurred - avoid doing the same thing. In my case if I selected Bake\475 degrees or higher it would hang up with a code F13. If I used any temperature below 475 it was okay. This is a common problem and it doesn't sound like customers are getting much satisfaction. Hope this helps! Truly, Ticked Off!
