LG Dryer PS Error Code
What it means
LG identifies PS as improper voltage at the dryer power cord; the article notes that reversed white and red terminal-block connections can be a cause.
Try this first
- Check that the dryer power cord is securely connected and installed correctly.
- At the home's electrical panel, turn the dryer circuit breaker off for at least 10 seconds, then turn it back on.
- Make sure the dryer is connected to a grounded outlet matching its 240-volt rating.
- If the supply or cord installation is uncertain, have it checked by a qualified installer or electrician.
- If PS remains after the electrical checks, request appliance service.
Can I keep using it?Do not rely on dryer heat until the power-supply or cord-installation issue has been corrected.
Repair usually required?If the electrical supply and cord installation are correct but PS remains, request dryer service.
