RECOMMENDED CORRECTIVE ACTION PROCEDURE
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 1000Ω and 1200Ω . 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
1000Ω and 1200Ω . 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).
