PSLG Dryer — LG Dryer PS Error Code
Power supply anomaly detected
Severity
Critical
Difficulty
Moderate
Est. Cost
What's Happening
The dryer detected an electrical anomaly in its power supply. On gas dryers, this can mean the gas supply is interrupted. On electric dryers, it may indicate incorrect voltage or a failing power supply circuit on the control board.
How to Fix It
For electric dryers, check that both 240V breakers are ON and the outlet is providing proper voltage. For gas dryers, verify the gas supply valve is open. If power is correct, the main control board may have a power supply circuit failure requiring professional service.
Frequently Asked Questions
What does PS mean on an LG dryer?
PS indicates a power supply problem. The dryer detected an electrical anomaly — either incorrect voltage (electric) or interrupted gas supply (gas models).
How do I fix the PS error on my LG dryer?
Check both 240V breakers for electric models, or the gas supply valve for gas models. If power supply is correct, the control board may need service.
Is PS different on LG gas vs electric dryers?
Yes. On electric dryers, PS usually means a voltage issue. On gas dryers, it can mean the gas supply is interrupted or the igniter circuit has a problem.
