LG Dryer Error Code nP
No current at the heater. nP means no current is detected at the heater, which LG says normally points to the home's electrical supply. Electric dryers need a 240V circuit; if half of it is out, the drum can turn but there is no heat.

- Owner fix: Often fixable with the safe checks on this page. Call a pro if the code comes back.

Likely causes
- A tripped half of the double-pole dryer breaker
- Loose power cord connection
- Outlet not supplying full 240V
Safe checks you can do
Safety: Unplug the dryer before moving it or cleaning the duct. On a gas dryer, do not disconnect or work on the gas line, valve or burner. If you smell gas, leave the house and call your gas company from outside.
- Make sure the power cord is firmly plugged into a grounded 240V outlet that matches the rating plate.
- Turn the dryer's breaker off for at least 10 seconds, then back on.
- If it still shows nP, have a licensed electrician check the outlet. Do not open the outlet or the terminal block yourself.
When to call a pro
- The outlet checks out and the dryer still will not heat
- Any time you smell burning or gas, see sparks, or would need to open a panel
