What Does Error nP Mean?
The LG dryer error code nP indicates that there is no power detected at the heating circuit, which typically results in the dryer drum spinning without producing heat. This issue is often related to electrical supply problems to the heater circuit. Common symptoms include the display showing 'nP' after a few minutes of operation and the dryer shutting off mid-cycle. Potential causes include loose or improperly connected power wiring, a tripped or weak circuit breaker, or insufficient 240V supply to the dryer.
Common Symptoms:
- Dryer drum spins but no heat
- Display shows nP after a few minutes of run
- Dryer shuts off mid‑cycle with nP
Possible Causes
- No current detected at heater due to electrical supply issue (high)
- Loose or improperly connected power cord or wiring (medium)
- Tripped/weak circuit breaker or partial 240V supply (medium)
How to Fix Error nP
DIY Fix Basic Power Checks
- Ensure dryer is unplugged and then fully re‑seat the power cord into a proper 240 V grounded outlet
- Check home circuit breaker for tripped dryer circuit and reset if needed
- Try a different compatible dry 240 V outlet if available
Technician Only Electrical Supply and Internal Wiring Inspection
- Verify proper 240 V supply at dryer terminals with a multimeter
- Inspect internal wiring harness and connections to heater circuit for continuity and secure attachment
- Test thermal fuse, high‑limit thermostat, and heater element continuity
Parts needed: multimeter, replacement wire/connectors, thermal fuse/thermostat/heater element if faulty
- If you are not comfortable working with high voltage electrical systems
- If proper 240 V power is confirmed at the outlet but nP error persists
- If internal wiring or components beyond the power supply appear damaged
