Hello my name isXXXXX will be assisting you with this problem today. Thanks for trusting us to help you with this appliance question.
The repair guy may have been wrong, The meaning of the error code and the corrective actions are listed below.
Bad Micro Identification.
Bad EEPROM Identification/Checksum error.
1. (F10 only) Check 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.
2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply power.
3. (F11, 12 & 13) If fault returns upon power-up, replace EOC.
Basically F10 can mean the oven sensor has failed, This would need to be checked with a ohm meter, If the sensor does not read around 1080 ohms at room temp then it is bad and will need to be replaced....The cost would be allot less.
If the sensor reads on or near 1080 ohms at room temp then yes the control board would need to be replaced.
If you can give me the model number I can look up the part numbers :)
