What we can confirm
Code nP, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
nP
This is the honest version of the commonest dryer complaint — it runs and everything comes out cold. On an electric machine it points straight at the 240-volt supply, and the usual cause is half of a double breaker that has tripped: the motor runs on one leg, the element needs both, so the machine looks alive and heats nothing. After that it is the thermal cutoff, which is a safety part that opens when a blocked duct has overheated the machine, and only then the element itself.

What it narrows down to
The machine is tumbling but no power is reaching the heat

What else belongs to the dryers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
The cycle was interrupted by the power going away
Not an error — the panel is locked
The machine has no numbers to show you, so it reports by which lights blink
The sensor that measures the dryer's heat is out of range
The machine cannot confirm the door is closed
The drum is not turning when the machine asks it to
The machine is measuring how blocked its own exhaust is, and reporting a percentage
A ventless dryer cannot get rid of the water it has taken out of the load
The sensor that decides when the load is dry is not reporting
A machine with a steam cycle cannot get the water it needs
The dryer reports by which indicator lights blink rather than by a number

What nP means on this make
This is the honest version of the commonest dryer complaint — it runs and everything comes out cold. On an electric machine it points straight at the 240-volt supply, and the usual cause is half of a double breaker that has tripped: the motor runs on one leg, the element needs both, so the machine looks alive and heats nothing. After that it is the thermal cutoff, which is a safety part that opens when a blocked duct has overheated the machine, and only then the element itself.
The other ways LG prints this one
nP · nE · nF · NP
LG publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with — OE, E03 and E21 are one condition on a washer, and Er dS, F dS and r dS are one sensor on different evaporators. They are one page here, so whichever of them you searched for, this is the right page.
Where this appears, and why not to clear it
On the appliance's own display. LG reports errors two ways: machines with a digital display show a code, and the laundry machines without one blink their indicator lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power. On a refrigerator you can also force the last code back onto the display by holding Freezer Temperature and Express Frz together for three seconds — LG documents that, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.
What to do about it
- Go to the breaker panel, switch the dryer's double breaker fully OFF and then ON again.
- Clean the lint screen and check the duct behind the machine and the vent outside.
- Run a heated cycle and feel the exhaust at the vent outside after ten minutes.
- If it is still cold, book it — a thermal cutoff that has opened means something restricted the air, and both need fixing.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 419-0291 and describe what the panel is doing before booking anything.
