Direct answer
On a supported LG dryer, nP means the dryer is not detecting proper electrical supply. Confirm the power cord is seated and both poles of the dryer breaker are on. Then have the outlet voltage and installation checked; do not use an adapter or extension cord.
What this covers
- LG dryers displaying nP
- The code and product type exactly match the official source
- Customer-accessible checks before component replacement
What it does not cover
- ×A similar code on another manufacturer or appliance type
- ×Codes omitted from the exact model manual
- ×Internal wiring, sealed-panel or live-electrical repair
Confirm nP on the exact model
ReversiblePhotograph the complete display, record the model tag and note the cycle stage. Similar-looking codes can mean different things on another product line.
Check the condition named by the code
ReversibleConfirm the power cord is seated and both poles of the dryer breaker are on.
Correct the remaining user-serviceable cause
ReversibleHave the outlet voltage and installation checked; do not use an adapter or extension cord.
Run one controlled verification
ReversibleRestore correct supply and run a brief timed cycle. Stop for arcing, heat, cord damage or a repeated breaker trip.
