NOTE: Before starng any test, cycle power to the oven (power o, wait 10 seconds, then power

on).

PROCEDURE: Before proceeding, verify the error code by entering the Diagnoscs Menu and

selecng “Error Diagnoscs”.

1. Enter the Diagnoscs Menu and select “Component Acvaon”. Touch or scroll to “Door

Latch Motor,” then touch “OK.” Touch “Latch Door.” Wait at least 15 seconds, then check

if latch status changes on screen. If status does not change, unplug microwave oven or

disconnect power and go to Step 2. If status changes, unplug microwave oven or disconnect

power and go to Step 5.

2. If the oven door did not unlatch, unplug connector P3 and check for connuity (on the latch

wire) between P3-5 and P3-7.

3. Disconnect J8 connector from Copernicus ACU.

4. Measure the resistance between connectors J8-2 and P5-1. It should be 500Ω to 3000Ω at

77°F (25°C).

5. If the resistance check is outside the range, replace the aected door latch assembly. Verify

that the error is gone.

6. Reassemble all parts and panels.

7. Plug in microwave oven or reconnect power.

8. Enter the Diagnoscs Menu and select “Component Acvaon”. Check the door status on

the screen by opening and closing the oven door.

9. If status does not change, unplug the oven or disconnect power.

10. Check for connuity with door open and closed at P3-5 to P3-6. Door open = innite

resistance. Door closed = zero resistance.

11. If connuity check is not correct, replace the door latch assembly. If all checks were correct,

replace Copernicus ACU.

12. Reassemble all parts and panels before operang.

13. Plug in microwave oven or reconnect power.

14. Verify operaon is normal. Enter the Diagnoscs Menu, select “Error Diagnoscs”, and clear

the history.
