6.
Disconnect connector J8 from the Copernicus Appliance Manager.
Measure the resistance between connectors J8‑2 and P5‑1. It should be
500 Ω to 3000 Ω at 77°F (25°C).

If the resistance check is outside the range, replace the door latch
assembly.
8.
Verify that the resistance between connectors J8‑2 and P5‑1 is 500 Ω to
3000 Ω at 77°F (25°C).
9.
If all checks were correct, replace Copernicus Appliance Manager.
10. Reassemble all parts and panels before operating.

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 Convect element (16.6 Ω to 18.4 Ω)
3.
If there is a short to ground, replace the corresponding element.
