How do I fix error code C-d1 on a Samsung ovens & ranges?

1. undefined: Disconnect power. Remove harness connected with lock motor. 2. undefined: Check micom switch (COM-NO). Measure resistance of lock motor coil: normal is 1750-1850 ohms at room temperature. 3. undefined: If motor coil resistance is abnormal: replace micro switch or lock motor. 4. undefined: If motor resistance is OK, check oven sensor. 5. undefined: Check if 120V AC is supplied to the motor and it is working. 6. undefined: If 120V not present, check wire harness connection to CN300 of main PCB. 7. undefined: Measure resistance at CN300 of main PCB (COM-NO: infinite ohms at room temperature). COM wire = white, NO wire = white. 8. undefined: If CN300 resistance is abnormal: replace main PCB or solder if pattern is damaged. 9. undefined: Check whether door locking switch is working normally. Normal voltage = AC 120V.

Error Code C-d1

Door locking error — door lock motor or switch malfunction during self-clean locking sequence

Moderate

Address soon - your appliance may not work properly

What This Means

Harness not connected with door lock switch and motor; Door lock motor coil resistance out of range; Door lock motor not receiving 120V AC; Door locking switch failure; Wire harness not connected to CN300 of main PCB

How to Fix

1
Disconnect power. Remove harness connected with lock motor.
2
Check micom switch (COM-NO). Measure resistance of lock motor coil: normal is 1750-1850 ohms at room temperature.
3
If motor coil resistance is abnormal: replace micro switch or lock motor.
4
If motor resistance is OK, check oven sensor.
5
Check if 120V AC is supplied to the motor and it is working.
6
If 120V not present, check wire harness connection to CN300 of main PCB.
7
Measure resistance at CN300 of main PCB (COM-NO: infinite ohms at room temperature). COM wire = white, NO wire = white.
8
If CN300 resistance is abnormal: replace main PCB or solder if pattern is damaged.
9
Check whether door locking switch is working normally. Normal voltage = AC 120V.
