What to check, in order
- Check the plug
The power cord should be pushed firmly into a grounded outlet that matches the dryer's rating plate: 240 V.
- Reset the breaker
Turn the dryer's circuit breaker off for at least 10 seconds to clear any power surge, then back on.
- Have the outlet checked
If it continues, LG suggests a licensed electrician checks that the outlet is supplying the right voltage.
When to call an engineer
If the outlet is fine and nP stays, LG says the dryer needs service.
Good to know
- nP and PS come from LG's US pages, which describe electric dryers on a 240 V outlet.
Quick answers
What does the LG nP error code mean?
The dryer can't detect any current at its heater, so it won't heat. LG says this normally points to the electrical wiring in the home.
Can I fix LG nP myself?
Easy (about 5 minutes). Start with: check the plug; reset the breaker; have the outlet checked. If the outlet is fine and nP stays, LG says the dryer needs service.
Is LG nP worth repairing?
Worth fixing. Often a loose plug or a tripped breaker. If not, the fix is usually in the home's wiring, so an electrician is the person to call first.
