What's Happening
The oven exceeded its maximum safe temperature due to a control board failure. A welded relay on the control board keeps the heating element energized continuously, causing uncontrolled heating. This is the most serious oven error.
How to Fix It
Disconnect power immediately. Once cooled, the control board needs replacement since a welded relay is an internal board failure that can't be repaired. Do not attempt to use the oven until the board is replaced.
