Error codenP
ApplianceDryer
Quick answer
nP on an LG dryer means no current is detected at the heater, which usually points to the home wiring.
Model compatibility: LG reuses codes across series and model years, so nP may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
No current detected at the heater (usually home wiring).
An nP code means the dryer detects no current at the heater. LG says this normally indicates a problem with the electrical wiring in the home, and the dryer may not be heating.
Steps from the manual
Check that the power cord is securely plugged into a grounded outlet that matches the 240 volts on the dryer’s rating plate.
At the home’s main, turn the dryer’s circuit breaker off for at least 10 seconds to clear the power surge inside the breaker.
If nP remains, have the home outlet checked by an electrician to confirm the correct voltage reaches the dryer.
If the outlet checks out and the dryer still is not heating, it needs a repair service.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
