C-d1
Door lock
1 .
Disconnect power . Open the back cover .
Check whether harness has been connected with door
lock switch and motor .
2 .
Confirm resistance value of door lock motor is
correct(R=1750~1850Ohm) .
3 .
With door lockout activated, measure voltage of harness
connector plugged into door lock motor .
(Normal Voltage : AC 120V)
4 .
Check whether door locking switch is working normally .
“C-d1”
* Disconnect power .
* Disconnect harness connected to a Lock motor .
* Door lock position switch check (door open: com-NO)
* Measure resistance of Lock motor Coil.(1750~1850Ω
at the room temperature)
* Check whether voltage(AC 120V) is supplied
to lock motor and motor operation .
* Check whether wire harness is connected
normally into CNS300 on main PCB .
* Measure resistance of CNS300 on main pcb .
(COM-NO: ∞ at the room temperature)
* COM : orange color
* NO : yellow color
* Repair damaged harness or Replace .
* Replace micro switch or Lock motor .
