Failure/Error Display Codes
Suggested Corrective Action Procedure
1.
Press CANCEL>CANCEL>START to enter the Diagnostics Mode and verify the error
code.
2.
If an F1 error code is displayed, unplug range or disconnect power. Replace the oven
control and then go to Step 4.
3.
If an F2 error code is displayed, unplug range or disconnect power. Replace the user
interface (keypad membrane) and then go to Step 4.
4.
Replace all parts and panels before operating.
5.
Plug in range or reconnect power.
6.
Verify operation is normal. Go to the Diagnostics Mode and scroll to the Faults display to
clear faults.
1.
Press CANCEL>CANCEL>START to enter the Diagnostics Mode. At the first screen,
verify the main oven sensor temperature readout. If it is available, verify the warming
drawer sensor temperature readout.
2.
Continue in the Diagnostic Mode to verify the error code.
Oven Temp Sensor
3.
If an F3E0 error code is displayed and the main oven sensor temperature reading is near
room temperature, unplug range or disconnect power. Replace the main oven sensor, as a
failure at high temperature may be the cause of the fault. Then go to Step 9. If the sensor
does not read room temperature, go to Step 5.
4.
If an F3E2 error code is displayed and the warming drawer sensor temperature reading is
near room temperature, unplug range or disconnect power. Replace the warming drawer
sensor, as a failure at high temperature may be the cause of the fault. Then go to Step 9. If
the sensor does not read room temperature, go to Step 5.
5.
Check all sensor connections on the harness and board.
6.
Disconnect sensor from the harness.
Warming Drawer Sensor
7.
Measure the oven sensor resistance (between connector pins). It should read between
1,000 and 1,200 . Measure the resistance from the sensor connector pins to the sensor
casing for a possible short. If the resistance measurement is out of range, or if a short is
found, replace the sensor.
8.
Inspect the wire and connectors from the control to the sensor. If any damage is noted,
replace the harness.
9.
Replace all parts and panels before operating.
10. Plug in range or reconnect power.
11. Verify operation is normal for longer than 1 minute. Go to the Diagnostics Mode and scroll
to the Faults display to clear faults.
