The F2 code indicates a stuck relay. You will have to replace the relay board. It may be a stand alone board or it may be part of the ERC Electronic Range Control. If you know how to check you won't have to call a tech.

This is from manufacture service manual:
-F2- Alarm Heating Mode High Temperature
Is activated when the ERC senses a runaway heat condition or when the temperature exceeds
“runaway limits”. The ERC will beep until the cancel or another function is selected. If the alarm
repeats the F2 alarm check the oven sensor and wiring after fi rst checking for a stuck relay. If alarm
goes away verify the oven will complete a clean cycle without any type of failure.
Another words the problem with oven sensor or relay board.

PROCEDURE: Before proceeding, press OFF, OFF, START to enter Diagnostic
mode and verify the error codes. Ensure AM software, UI software and EEPROM
CHECKSUM versions appear on the lower text line. If AM software and EEPROM
versions do not appear, UI and AM may not be communicating. Verify this for the
lower oven UI and for the microwave (upper oven) UI. The lower oven UI will show
the AM software version for the lower oven appliance manager, and the microwave
UI will show the AM software and EEPROM versions for the microwave appliance
If the lower oven UI is not displaying the AM software version, go to UI IS NOT
DISPLAYING AM SOFTWARE VERSION.
If the upper oven UI is not displaying the AM software and EEPROM versions,
go to UPPER OVEN UI IS NOT DISPLAYING THE AM SOFTWARE AND
If lower oven UI and microwave UI are both displaying an error, go to LOWER
OVEN UI AND MICROWAVE UI ARE BOTH DISPLAYING AN ERROR.
UI IS NOT DISPLAYING AM SOFTWARE VERSION:
A. Unplug oven or disconnect power.
B. Open the back panels and make sure the P6 and P2 connectors are fully
inserted on the appliance manager and on the lower oven user interface board.
- If they are not plugged in, plug in connectors and go to step F.
- If they are plugged in, go to step C.
C. Visually inspect all wires between P6 on the appliance manager and P2 on the
lower user interface.
- Make sure wires are not cut or pinched.
- If the wires appear to be intact, perform a continuity check between
P6-1 of the appliance manager and P2-1 of the user interface board.
Complete for P6-2(AM) to P2-2(UI), P6-4(AM) to P2-4(UI) and P6-5(AM) to
P2-5(UI). All the measurements made should be less than 5 ?. If any of
these measurements exceeds 5 ?, go to step E.
D. Replace the appliance manager. Ensure all connectors are properly inserted.
E. Replace the wiring harness (signal). Ensure all connectors are properly inserted.
F. Replace all parts and panels before operating.
G. Plug in oven or reconnect power.
H. Observe for longer than 1 minute to determine if error has been repaired.
I. If error does not appear, initiate a bake cycle. Let the cycle run for at least
- If no error occurs, cancel the cycle, the problem has been repaired.
- If error occurs again, restart the troubleshooting procedure at step A.
At step D, replace the lower oven user interface board if appliance
manager has already been replaced.
- If both are replaced the problem has been repaired.
Let me know,if needed further assistance.
Hope i helped you.
