  If the FLOW SENSE indicator shows four bars during the drying cycle on your LG dryer, this indicates restrictions in the external dryer venting, ductwork due to lint buildup or debris, or many turns/restrictions in the ductwork. Consider installing a shorter or straighter duct run. The ductwork should be checked and cleaned soon. The dryer can still be used, but drying times may be longer. Note that if exhaust restrictions are sensed by the FLOW SENSE system, the indicator will remain on for two hours after the cycle ends. Opening the door or pressing the POWER button will reset it.

  If your LG dryer displays PS, PF, or nP, it indicates that the electric dryer power cord isn't correctly connected, or the house power supply is incorrect. It can also mean that a house fuse is blown, the circuit breaker has tripped, or there's a power outage. Check the power supply and the power cord connection to the terminal block, referring to the Connecting electric dryers section of this manual for instructions. Also, reset the circuit breaker or replace the fuse, without increasing its capacity. If there's a circuit overload, have it corrected by a qualified technician.
