Insufficient voltage to dryer

Est. Cost
What's Happening
The dryer detects insufficient voltage. LG electric dryers require a 240V connection. This often happens when plugged into a 120V outlet, or when one leg of the 240V circuit has tripped at the breaker panel.
How to Fix It
Check your breaker — both breakers for the dryer circuit must be ON. Verify the dryer is plugged into a 240V outlet (not 120V). If voltage is correct at the outlet, the power cord connections inside the dryer may be loose.
Frequently Asked Questions
What does nP mean on an LG dryer?
nP stands for No Power — the dryer isn't receiving the correct 240V needed to operate. It's usually a breaker or outlet issue, not a dryer problem.
How do I fix the nP error on my LG dryer?
Check that both breakers for the dryer circuit are ON. Verify the outlet is 240V. If one breaker tripped, reset it. If voltage is correct, check the power cord connections inside the dryer.
Can a tripped breaker cause an LG dryer nP error?
Yes. Electric dryers use two breakers (240V). If one trips, the dryer gets only 120V, which triggers the nP error. Check both breakers in your panel.
