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.
Disconnect connector P3 from Copernicus Appliance Manager, and
measure the resistance of the sensor between P3‑1 and P3‑2. Test for
1000 Ω to 1200 Ω at 77°F (25°C). Check sensor for short to ground. If
checks on sensor are not correct, replace sensor and repeat the checks.

3.
Reassemble all parts and panels before operating.
4.
Plug in oven or reconnect power.
5.
Enter Diagnostics mode and select "Sensors & Switches" to verify if
the temperature shown in the Cavity Temp display is correct (ambient
temperature). If it is, go to Step 8.
6.
If not, unplug oven or disconnect power.
7.
Replace the Copernicus Appliance Manager board.
NOTE: On the status screen, the unit of measurement is Celsius.
8.
Reassemble all parts and panels before operating.
9.
Plug in oven or reconnect power.
10. Verify operation is normal. Enter Diagnostics mode, select "Error
Diagnostics," and clear the history.

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.
Remove meat probe if connected.
3.
Disconnect connector P3 from Copernicus Appliance Manager.

4.
Check connector jack resistance between P3‑3 and P3‑4. If it is not 0 Ω,
the jack assembly is working properly. Go to Step 6.
5.
If it is 0 Ω, change the jack assembly.
6.
Plug in the meat probe and check for short to ground or open.
7.
If checks on meat probe are not correct, replace the meat probe. At 77°F
(25°C), the resistance should be approximately 50 KΩ.
8.
If they are correct, replace the Copernicus Appliance Manager.
9.
Reassemble all parts and panels before operating.
10. Plug in oven or reconnect power.
11. Verify operation is normal. Enter Diagnostics mode, select "Error
Diagnostics," and clear the history. Check the meat probe reading by
entering Diagnostics mode and selecting "Sensors & Switches." The meat
probe should detect the ambient temperature.
