LG Error Code nP
No power to gas valve (gas)
Common Causes
- 1Gas valve failure
- 2Igniter issue
Gas dryer repairs involve natural gas or propane. If you smell gas strongly, evacuate the area, do not operate electrical switches, and call your gas utility emergency line. Never use an open flame to test for gas leaks.
Step-by-Step Troubleshooting
- 1
Verify the gas supply valve (usually located on the gas pipe behind or beside the dryer) is fully open
- 2
Check if other gas appliances in the home are functioning — if not, there may be a gas supply interruption or the main shut-off valve is closed
- 3
Access the gas valve solenoid coils by removing the lower front panel — observe if the igniter glows orange during the heat cycle start
- 4
If the igniter glows but gas does not flow, the gas valve solenoid coils have failed — LG gas dryers have two coils (booster and holding) that must both function
- 5
Test each solenoid coil for resistance — the booster coil should read approximately 300-400 ohms and the holding coil approximately 1000-2000 ohms
Pro Diagnostic Tip
LG gas dryer valve coils have a known failure pattern: the dryer heats initially but stops heating mid-cycle, then works again after cooling down. This is the classic thermal fatigue pattern of the booster coil — the coil works when cool but opens circuit when it heats up from the burner proximity.
