Make: KitchaidModel: KEMS308SSS00
Two appliance repair companies. Neither approved Kitchaid service techs. Wrong boards ordered. Gave up.
You are having a communication error between the appliance. 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
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 Ω. If any of
these measurements exceeds 5 Ω, 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.
Here is the breakdown on your unit:
Number 10 is the appliance manager and number 5 is the lower oven interface. Make sure you test all of the pins the way it says in the instructions.
Here are the part numbers you will need:
Appliance Manager - W10119143
Oven Interface - W10118734
