Hello.

 

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

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 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

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.

 

Here is the breakdown on your unit:

CONTROL PANEL PARTS

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
