Error codePS
ApplianceDryer
Quick answer
PS on an LG dryer indicates improper voltage at the power cord, possibly from reversed white and red wires at the terminal block.
Model compatibility: LG reuses codes across series and model years, so PS may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Improper voltage from power cord (possibly white and red wires reversed at terminal block).
A PS code on an LG dryer indicates improper voltage with the power cord. The manual says it could be caused by the white and red wire connections being reversed on the dryer’s terminal block.
What the manual tells you
Check the power cord installation on the back of the dryer and compare it with the owner’s manual installation instructions for the cord.
Make sure the cord is plugged into a grounded outlet that matches the 240 volts on the rating plate.
Turn the dryer’s breaker off for at least 10 seconds.
If the dryer was just installed, call the installer to check the cord installation and the wall outlet. Terminal block wiring is work for the installer or a technician.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
