♨️ LG dryer displays dC error (door code)

🔧 Troubleshooting Steps

1. Check the door is fully closed and latched. Press firmly on the door near the latch area
   ✓ Expected: Door latches with audible click
2. Test the door switch (microswitch in the latch) for continuity. Should show continuity when door is closed
   ✓ Expected: Continuity when closed
3. If the switch tests good, check the wiring harness from the door switch to the control board for broken wires (common at the flex point near the hinge)
   ✓ Expected: Wires intact, no broken strands
4. If dC persists with a good switch and wiring, the control board's door switch input circuit may be faulty
   ✓ Expected: Control board input circuit functional
