LG Dryer nP error code
The nP error means your LG dryer cannot detect any electrical current reaching the heating element. This is most commonly caused by a problem with the home's electrical supply rather than the dryer itself — typically a tripped circuit breaker or insufficient voltage at the wall outlet. LG dryers require a dedicated 240V outlet to operate the heater correctly. If the circuit breaker reset and outlet checks do not resolve it a licensed electrician should inspect the home wiring before calling a dryer technician.
Common causes
- Power cord is not securely plugged into the wall outlet
- One leg of the 240V circuit has tripped at the home's main circuit breaker
- Home outlet is not supplying the correct 240V required for the dryer heater
- Power surge caused a fault in the circuit breaker
- Dryer is not connected to a grounded 240V outlet matching the rating plate
How to fix it
-
1
Make sure the power cord is firmly plugged into a grounded 240V outlet matching the dryer's rating plate
-
2
Go to the home's main electrical panel and turn OFF the dryer's circuit breaker for at least 10 seconds
-
3
Turn the circuit breaker back ON and check if the nP error has cleared
-
4
If nP persists the home outlet may not be supplying the correct voltage — contact a licensed electrician to inspect and test the outlet
-
5
If the outlet checks out correctly and nP still shows the dryer itself will need a professional repair service
