What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Check that the dryer is unplugged or isolated at the breaker before any exterior observation; if power cannot be isolated safely, stay clear and call an electrician.
- Inspect only the visible plug, cord, and outlet without moving the dryer or opening a cover; if any part is loose, hot, scorched, cracked, or damaged, leave power off.
- Compare the outlet type with the dryer's rating plate without electrical testing; if they do not clearly match, contact a licensed electrician or qualified installer.
- Check whether PS appeared from the first use after installation; if it did, keep the dryer off and have the installer verify the cord and supply.
Applicability
Regional guidance · LG 240-volt electric dryers that display PS · United States
LG's US guidance discusses power-cord and 240-volt installation conditions; other dryer formats and markets require their own model-specific electrical documentation.
Reset or retry steps
- A breaker reset cannot prove that the power cord is installed correctly; do not resume operation if PS remains or returns.
- Do not remove the terminal-block cover, move conductors, or follow internal wiring steps as an owner reset.
When to call a technician
- Use a licensed electrician or qualified installer for PS, especially after a new installation or when the outlet, cord, or supply is uncertain.
- Request LG service only after the qualified electrical supply check if PS remains with the correct installation.
- Leave the area and call emergency services for fire, persistent smoke, or active sparking.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Do not keep running a dryer that overheats, smells hot, or has a severe airflow restriction warning.
A restricted vent can increase dryer fire risk; stop if there is burning smell, smoke, or repeated overheating. Persistent headaches, dizziness, nausea, or weakness near a gas appliance can be a carbon monoxide warning: leave the area, ventilate only if safe, and call emergency services or qualified service for a CO check.
- Safe next step
- Stop the cycle, let the dryer cool, clean the lint screen, and check only visible vent restrictions before retrying.
- Stop when
- Airflow stays weak, the dryer overheats, the outside vent cannot open, or gas/electrical supply concerns appear.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Incorrect supply voltage for the electric dryer
- Power-cord installation or terminal connection requiring qualified correction
- Loose, damaged, or mismatched power cord or outlet
- Home branch-circuit issue
FAQ
What does LG Dryer code PS usually mean?
LG documents PS as a warning that the dryer detected improper voltage at the power cord or its installation. Model context matters: LG separates PS, an improper-voltage or power-cord-installation display, from nP, where current is not detected at the heater.
Can I keep using the dryer with code PS?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Do not open the terminal-block cover or rearrange power-cord conductors; this is qualified electrical installation work.
When should I call a technician for LG PS?
Use a licensed electrician or qualified installer for PS, especially after a new installation or when the outlet, cord, or supply is uncertain. A qualified technician may check Power cord, Home dryer outlet or circuit, Terminal block, and Dryer wiring harness against the model's service information before treating any part as failed.
