Can I fix LG code nP myself?

Start with these safe checks: Make sure the power cord is fully plugged into a grounded 240 V outlet that matches the dryer's rating plate. Turn the dryer's breaker off for at least 10 seconds and back on. If nP continues, have a licensed electrician check the outlet's voltage. If the outlet is fine, request dryer service.

When should I call a technician for code nP?

If nP continues, have a licensed electrician check the outlet's voltage. If the outlet is fine, request dryer service. Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician.
