1.
Unplug range or disconnect power.
2. Inspect control board connector P10 for a backed out terminal
or loose connection. If found, reconnect or replace harness and
go to Step 10. If not, go to Step 3.
3. Disconnect control board connector P10. Measure resistance
across P10-3 and P10-4. At room temperature, the thermal
sensor should read between 1000 and 1200 . Reconnect
P10. If test results are good, go to Step 4. If test results are not
correct, go to Step 9.
4. Replace all parts and panels before operating.
5.
Plug in range or reconnect power
6. Enter a cook function (i.e., Bake). If the error code doesn't
reappear after 20 seconds, go to Step 13. If the error code
reappears, go to Step 7.
7. Unplug range or disconnect power.
8. Replace main control and go to Step 10.
9. Inspect connection at main oven thermal sensor. Disconnect
and measure resistance across thermal sensor terminals. At
room temperature, the thermal sensor should read between
1000 and 1200 . If resistance measured out of range, replace
thermal sensor. If resistance measured within range, replace
harness.
10. Replace all parts and panels before operating.
11. Plug in range or reconnect power
12. Enter a cook function (i.e., Bake) and verify the error code
doesn't reappear after 20 seconds.
13. Verify operation is normal. Enter the diagnostic mode to view the
"Faults" screen. Press START TIME or DELAY START to clear
each Fault code(s).
