Error Code F10

Door Lock Failure — Door locking motor failed to complete lock or unlock operation

What This Means

Loose or disconnected wiring at door locking motor or micro switch; Defective door locking micro switch; Failed door locking motor; Loose CN02 connector on Main PCB; Failed Main PCB (door lock relay)

How to Fix

1. 1

   Disconnect power.

2. 2

   Check terminal looseness of micro switch and door locking motor connectors at the latch drive assembly (rear of range). Reconnect if loose — this resolves many F10 errors.

3. 3

   Test door lock micro switch resistance: Door latch open = continuity (below 2 ohm); Door latch locked = infinite. Micro switch holds position for 13 seconds during lock/unlock. If abnormal, replace micro switch.

4. 4

   Measure door locking motor resistance: normal approximately 2.6 kohm (flow chart) / 3.9 kohm ±10% (component test). Abnormal: infinite (open) or below 5 ohm (shorted). If abnormal, replace the door locking motor.

5. 5

   Check CN02 connector on Main PCB for looseness. Reconnect if loose.

6. 6

   If all above are normal, replace the Main PCB.
