LG Dryer Error Code PS — What It Means & How to Fix It

What Does This Error Mean?

The PS error means your LG dryer detected a power failure during a cycle. The electricity was interrupted and the dryer stopped mid-cycle. This is usually caused by a power outage or loose plug, not a dryer problem.

Affected Models

DLEX3900B
DLE7300WE
DLGX4201B
Most LG electric and gas dryers

Common Causes

Power outage or brief electrical interruption in your home
Loose power cord connection at the wall outlet
Tripped circuit breaker or blown fuse in the electrical panel
Faulty wall outlet not providing consistent power
Power cord damaged or connections loose at the dryer terminal block

How to Fix It

Check if there was a recent power outage in your area.

If yes, simply restart the dryer cycle. The PS error should clear.
Make sure the power cord is firmly plugged into the wall outlet.

Dryer plugs are heavy and can work loose over time, especially if the dryer vibrates.
Check the circuit breaker panel for a tripped breaker.

Electric dryers use a double breaker (240V). Both sides must be on.
Unplug the dryer for 1 minute, then plug it back in.

This clears the PS error from the display.
Restart your drying cycle as normal.

If the PS error keeps returning without a power outage, the outlet or wiring may need inspection.

When to Call a Professional

If the breaker keeps tripping or the outlet seems faulty, call a licensed electrician. Do not try to repair electrical wiring yourself. A faulty outlet or wiring issue can be a fire hazard. Electrician visits typically cost $75–$150 for a diagnostic.

Frequently Asked Questions

Is the PS error something wrong with my LG dryer?

Usually no — the PS error just means power was interrupted. It is like an alarm clock blinking after a power outage. Just restart your cycle and the error should go away.

Why does my LG dryer keep showing PS?

If there was no power outage, check the plug and circuit breaker. A loose plug or weak outlet connection can cause repeated PS errors. If the breaker trips when the dryer runs, you may have an electrical wiring issue. Call an electrician to inspect the circuit.

Do I need to restart the full drying cycle after a PS error?

Yes — the dryer does not resume automatically after a power failure. You will need to select your settings and start the cycle again. Your clothes may still be damp, so run a full cycle.
