I was using my range and heard a pop and saw a flash. It came from the left front element. Took the cover off and the simmer control board and cooktop lockout board were scorched. Got online and found other people had this problem. I didn't see any other damage. I replaced the boards and plugged it in. The display started flashing a f40 code. Found this was the cooktop lockoutboard. I also noticed the display was very dim. Checked the voltage at the plug and range and had 242 volts at both. I smelled something getting hot, and unplugged it. On the big display board there is what looks like a small coil or transformer. This is what was getting hot. It is held to the board with a tie strap. All the cooktop elements worked but not the elements in the oven. Could it be that the display board is bad. Any help would be appreciated. Thank you.
