Lost timer beep first and now also microwave beeps. Was going to order control Part Number: AP4588518 planning on removing first to see if it has the speaker on it before I order a $300 part perhaps you could confirm if that is the replace part.
On the back of the display board W10312206 (which is for the oven part of the unit) there is a speaker. Also on the back of control for the microwave W10460454 there is the speaker. If the audible tones for both parts of the unit have stopped then you would need to replace both controls.
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.
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
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
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
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
10. Replace the wiring harness (signal). Ensure all wiring connections are
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

oven UI and the P2 connector on the microwave UI and fully
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.

board if lower oven UI has been replaced.)
