F6 E0 means that you are having a Lost Communication Error between the appliance; unfortunately this is the worst error code you can get on this model because there is no way to test for which part is definitely bad. You'll need to uninstall the oven and remove the top panel and the left side panel. make sure the wires are secure going from the interface control board to the program manager board on the left side of the oven. If it checks good, you'll need to make a guess and just replace one of the control boards because one of them is bad and you can't test to see which one is faulty.
Here is the actual tech manual instructions for that code:
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 manager.
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 EEPROM VERSIONS.
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 ohms. If any of these measurements exceeds 5 omhs, 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 1 minute.
- 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.
Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using Fixya, and have a nice day.
