I have a "lost communication" error code F6 EO shown on the control panel. It shows up on both the oven and the microwave. It happened as I was using the microwave. I hit "stop" on the microwave panel and it cleared the "lost communication" error code message. The microwave has worked fine since. Can you enlighten me as to what is going on? Thanks.

Larry for Model Number KEMS308SSS04

ANSWER Hello Larry. SUGGESTED CORRECTIVE ACTION PROCEDURE PROCEDURE: Before proceeding, perform steps 1 through 3 of “To Enter Diagnostics Mode.” Ensure AM software, UI software and EEPROM CHECKSUM versions appear on the lower text line. If AM software and EEPROM version do not appear, UI and AM may not be communicating. Verify this for the UI. 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 DISPLAYNG THE AM SOFTWARE AND EEPROM VERSION.” 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: 1. Unplug oven or disconnect power. 2. Check both fuses in the microwave module and the fuse located next to the appliance manager. If either is open or disconnected, it will break contact for the communication line and cause this error. 3. Check microwave module appliance manager for damage on corners of board. Broken traces can cause communications failure. 4. Check the harness and probe jack for a short to ground. 5. Replace all parts and panels. Unplug meat probe and plug in oven or reconnect power. If error goes away, the meat probe sensing line is grounded. 6. Unplug oven or disconnect power. 7. Open the back panels and make sure the P6 connector on the appliance manager and the P2 connector on the user interface are fully inserted. If not, plug in connectors and go to Step 9. If fully plugged in, go to Step 6. 8. Visually inspect all of the wires between P6 on the appliance manager and P2 on the user interface. Make sure the 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. Do the same for P6-2 (AM) to P2-2 (UI), P6-4 (AM) to P2-4 (UI), and P6-5 (AM) to P2-5 (UI). All of the checks should result in a reading of less than 5O. If any of these checks fail, go to Step 8. If these checks pass, reconnect P2, then go to Step 7. 9. Replace the appliance manager. Ensure all connectors are properly seated. 10. Replace the wiring harness (signal). Ensure all wiring connections are made. 11. Replace all parts and panels before operating. 12. Plug in oven or reconnect power. 13. Observe for longer than 1 minute. 14. If the error does not appear, initiate a Bake cycle. Let the cycle run at least 1 minute. If no error occurs, cancel the cycle. The problem has been repaired. If the error occurs again, restart the troubleshooting procedure at Step 1 (except in Step 7 replace the user interface board if the appliance manager has already been replaced). If both are replaced, the problem has been repaired. LOWER OVEN UI AND MICROWAVE UI ARE BOTH DISPLAYING AN ERROR: 1. Unplug oven or disconnect power. 2. Open the back panels and make sure the P2 connector on the lower oven UI and the P2 connector on the microwave UI and fully inserted. If they are not, plug the connectors in and go to Step 6. If they are plugged in, go to Step 3. 3. Visually inspect all the wires between P2 on the lower oven UI and P2 on the microwave user interface. Make sure the wires are not cut or pinched. If the wires appear to be intact, perform a continuity check between P2-1 of the lower oven UI and P2-1 of the user interface board. Complete for P2-2 (lower oven UI) to P2-2 (microwave UI), P2-4 (lower oven UI) to P2-4 (microwave UI) and P2-5 (lower oven UI) to P2-5(UI). All the measurements made should be less than 5O.. If any of these check fail, go to Step 5. If these checks pass, reconnect P2 and go to Step 4. 4. Replace the lower oven UI. Ensure all connectors are properly inserted. Go to Step 6. 5. Replace the wiring harness (signal) and proceed to Step 6. 6. Replace all parts and panels before operating. 7. Plug in oven or reconnect power. 8. Observe for longer than 1 minute to determine if error has been repaired. 9. 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 1. (Except in Step 4, replace microwave user interface board if lower oven UI has been replaced.)
