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](/services/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](tel:+13054190291) and describe what the panel is doing before booking anything.
