Error Code C-d1
Door locking information — door lock motor or switch malfunction
Moderate
Address soon - your appliance may not work properly
What This Means
Harness not connected properly with door lock switch and motor; Door lock motor coil resistance abnormal; Door lock switch not working; Main PCB relay fault
How to Fix
- 1
Disconnect power and open back cover
- 2
Check harness connection to door lock switch and motor
- 3
Remove harness connected to lock motor and measure resistance of lock motor coil (normal: 1750-1850 ohm at room temperature)
- 4
Check microswitch COM-NO contact
- 5
With door lockout operating, measure voltage at door lock motor harness connector (normal: AC 120V)
- 6
Measure resistance at CN300 of Main PCB (COM-NO: infinite ohm at room temperature)
- 7
Replace micro switch or lock motor if faulty
- 8
Repair damaged harness or replace Main PCB if relay is faulty
