LG Dryer nP Error Code
No power reaching the heater. Here is what it means and how to clear it, easiest fix first.
The dryer is not detecting current at its heater, so it may tumble but not heat. LG says this usually points to the home's power supply rather than the dryer. A common example is one half of the 240-volt double breaker tripping, or a poor connection at the outlet.
Electric dryers only.
How to fix LG nP
Check the plug
Make sure the dryer's power cord is pushed firmly into a grounded 240V outlet. If water is anywhere near the outlet or cord, switch off the breaker instead of touching the plug.
Reset the breaker
At the main panel, switch the dryer's double breaker fully off for at least 10 seconds, then back on. A breaker that has half-tripped can look on at a glance.
When to call a technician
If the code remains, have a licensed electrician test the outlet voltage. If the house supply is fine and the dryer still will not heat, book a dryer repair.
Parts that commonly cause nP
- circuit breaker
- power cord
- heating element
Order parts by your exact model number so they fit.

Frequently asked questions
What does nP mean on a LG dryer?
The dryer is not detecting current at its heater, so it may tumble but not heat. LG says this usually points to the home's power supply rather than the dryer. A common example is one half of the 240-volt double breaker tripping, or a poor connection at the outlet.
Can I fix LG nP myself?
Often. The first steps above are safe checks a homeowner can do. If they don't clear nP, the cause is likely a worn part that needs replacing.
What if nP keeps coming back?
A code that returns after a reset and the checks above usually means a part is wearing out. Note when nP appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
