What causes the np error?
- Power cord wired incorrectly at the terminal block
- One leg of the 240V supply lost (tripped breaker)
- Blown house fuse
- Faulty wall outlet
- Loose connections at the terminal block
How to fix LG np — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Check both breakers
An electric dryer needs 240V from a double breaker. If one side tripped, the dryer runs but never heats. Flip the dryer breaker fully off, then back on.Safety warning: If the breaker trips again immediately, stop and call an electrician. - Power reset the dryer
Unplug the dryer for a minute and plug it back in firmly. A loose plug can cause the same symptom. - Inspect the power cord connection
With the breaker OFF, remove the terminal block cover on the back and check that the cord wires are tight and on the correct terminals per the manual.Safety warning: Turn the breaker off first and verify no power before touching the terminal block. If you are unsure, call an electrician.
When to call a technician
- The breaker trips repeatedly
- You see burning or melting at the outlet or cord
- The terminal block looks burnt
- There is no 240V at the outlet
Frequently asked questions
My dryer runs but there is no heat. Is that nP?
It fits perfectly. The motor runs on 120V, but the heater needs the full 240V.
Can a tripped breaker cause nP?
Yes, it is the most common cause. Dryers use a double breaker, and one side can trip silently.
Is nP the dryer's fault?
Usually not. It points at the house wiring, breaker, or the cord connection, not the heating element.
