FAILURE ERROR LIKELY FAILURE CONDITION
F6 E1 Over temperature
SUGGESTED CORRECTIVE ACTION PROCEDURE
NOTE: Before starting any test, cycle power to the oven (power off, wait 10
seconds, and power on).
PROCEDURE: Before proceeding, verify the error code by entering the
Diagnostics mode and selecting "Error Diagnostics."
1. Unplug oven or disconnect power.
2. Check for elements shorted to ground. Check resistance of elements:
a. PX4-2 and PX3-2 to check Broil element (13.2 Ω to 14.6 Ω)
b. PX1-1 and PX3-2 to check Bake element (19 Ω to 21 Ω)
c. PX1-3 and PX3-2 to check Upper Convect element (15.2 Ω to 17.3 Ω)
3. If any element is shorted to ground, replace the element.
4. Check for shorted relays.
For Core Models: Disconnect PX1 and PX4 connectors
and check for shorts between:
a. PX1-1 and PX1-2 (Bake relay)
b. PX1-3 and PX1-4 (Up Convect relay)
c. PX4-1 and PX4-2 (Broil relay)

5. If there is a shorted relay, replace the Copernicus Appliance Manager
control. Go to Step 9.
6. If everything is correct, disconnect connector P3 from the Copernicus
Appliance Manager.
7. Measure the resistance of the oven sensor. It should be 1000 Ω to 1200 Ω
at 77°F (25°C).

9. Reassemble all parts and panels before operating.
10. Plug in oven or reconnect power.
11. Enter the Diagnostics menu and select "Sensors & Switches" to verify
that the corresponding oven temperature displayed is correct (ambient
temperature). If not, unplug oven or disconnect power, and replace the
Copernicus Appliance Manager board.
NOTE: On the status screen, the unit of measurement is Celsius.
12. Reassemble all parts and panels before operating.
13. Plug in oven or reconnect power.
14. Verify operation is normal. Enter Diagnostics mode, select "Error
Diagnostics," and clear the history.
