LG Dryer nP Error Code

No power reaching the heater. What it means, which models show it, and how to clear it, easiest fix first.

LGAll LG dryer codes

nP
Moderate DIY

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.

Difficulty

Start with the safe checks below; a worn part may need replacing.

Safety first: unplug the dryer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG nP

  1. 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.

  2. 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.

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.
