What dr Means
dr is a second, separately-displayed code LG's error-code list documents with the identical description it gives for Ad: the door motor doesn't reach its maximum or home position within 5 seconds. LG treats Ad and dr as two distinct code entries in its own documentation even though the underlying description is the same, so both are kept here rather than merged.
Common Causes of dr
- Auto door motor mechanism has failed or is obstructed
- Physical obstruction in the door's travel path
- Door motor wiring fault
🔧 One Safe Check You Can Try
As with Ad, rule out a physical obstruction in the door's travel path before assuming a hardware fault.
⚠ Why You Shouldn't Go Further Than That
- LG documents no troubleshooting steps beyond the obstruction check - this is an auto-door mechanism fault, not a homeowner repair.
- Forcing the door mechanism by hand when the motor is genuinely faulted can damage the drive components further.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
