Test Name Description Steps
TEST #4
User Interface
Input Voltage and
Communication
(same for L/R
oven)
This test is used to check the
UI board(s) input voltage and
communication. The UI board
operates at 14 VDC from the ACU.
In the case of a double oven range,
the F6E0 UI communication error
is only triggered by the secondary
(left) oven UI board. Therefore, this
test is used for the F6E0 as well as
no response on the (right) UI.
Examples:
1. 14 VDC Input
2. F1E0
3. F6E0
1. Unplug range or disconnect power.
2. Open console assembly to access the user interface.
3. Verify that all connectors are inserted all the way into the user interface board(s).
4. Disconnect the J4 connector from the User Interface board.
5. Use black probe on J4-4, red probe on J4-1, to measure the resistance on the board.
If it’s out of range 5.2K±2 KΩ, the user interface board is improperly functioning.
6. Use black probe on J4-4 and red probe on J4-3 in the board, to measure the resistance. If it’s out
of range 2K±1 KΩ, the user interface board is improperly functioning.
7. Plug in J4 connector.
8. Connect voltmeter between J4-4 (GND) and J4-1 (14 VDC). Plug in range or reconnect power.
If DC voltage is not present, unplug range or disconnect power and run test #1 to check if DC
voltage is provided by ACU from P9.
If DC voltage is present, unplug range or disconnect power and go to step 9.
9. Reassemble all parts and panels. Plug in range or reconnect power.
10. Wait 3 minutes before checking if there is an error.
If there is an error, go to service mode to check if the error code is F1E0 or F6E0 again.
