Error Code F-10

Door Lock Fail — Door lock motor failure during lock or unlock operation (during self-clean or lockout).

Also displayed as: F-10

How to Fix

1. 1

   Disconnect power to the range.

2. 2

   Check terminal looseness of the micro switch and door locking motor — if loose, reconnect and retest.

3. 3

   Measure resistance of the door lock micro switch (normally open type): door latch open = continuity, door latch locked = infinite. If readings are reversed or both show the same, replace the micro switch.

4. 4

   Measure resistance of the door locking motor: normal is approximately 2.6 kΩ; abnormal is infinite (open) or below 5Ω (shorted). If abnormal, replace the door locking motor.

5. 5

   If motor and switch check normal, check connector CN03 for looseness — reconnect if loose.

6. 6

   If CN03 is normal, check Power PCB voltage outputs at CN13: PIN1(GND) to PIN3 should be approximately 9V; PIN1(GND) to PIN4 should be approximately 4.5V to 5.5V.

7. 7

   If Power PCB voltages are abnormal, replace the Power PCB.

8. 8

   If voltages are normal, replace the Main PCB.
