Their boards are junk. Some have been known to magically start in self cleaning mode and run for hours at 500 degrees. There are web pages full of complaints from pissed off, or terrified owners. The Big W does not give a damn about it and will do nothing for those of us who own one. Same goes for the KA dishwasher boards. They are known fire starters. Try cutting the power to it for a few minutes. When you power it back up, it may show a "PF" (power failure) code, it might work, or it might show "F02," which is the code for, "the board is shot." The oven boards cost around $200.00.
