(F10 only) Check *RTD Sensor Probe & replace if necessary. If oven is overheating, disconnect power. If oven continues to overheat when the power is reapplied, replace EOC. Severe overheating may require the entire oven to be replaced should damage be extensive.
most likely its your temperature sensor in this, this is on the back wall inside the oven, you can order this @ http://www.repairclinic.com/SSPartDetail.aspx?s=t-790.9611-%3d%3dei1259650&PartID=1259650 for around $22.00, thanks Bryan
