Error Code F10

Door lock fail — door lock motor fails to complete lock/unlock cycle; detected when door lock switch does not operate properly after motor rotates twice

What This Means

Failed door lock motor (open or shorted); Failed micro switch (door lock position switch); Loose or disconnected wiring to lock motor or micro switch; Defective relay for door lock on Relay PCB

How to Fix

1. 1

   Plug in the unit and check door lock motor operation by pressing Clock button for 3 seconds (activates lockout); attempt to open the door — if door opens it is a wiring fault, if it does not open check motor

2. 2

   Unplug the unit

3. 3

   Check electrical wiring of relay in Relay PCB, wiring of locking motor and micro switch, and wiring of CN31 on Main PCB; reconnect any loose connectors

4. 4

   Measure resistance of door lock micro switch (normally open type) — with door unlatched: COM to NO should show continuity; in opposite state: infinite; if abnormal, replace the micro switch

5. 5

   Measure resistance of door lock motor — normal approximately 2.6 kOhm; abnormal: infinite (open) or below 5 ohms (shorted); if abnormal, replace the lock motor

6. 6

   If motor and micro switch are normal, replace the Relay PCB

7. 7

   If same phenomenon occurs after replacing Relay PCB, replace the Main PCB
