LG Dryer PS Error Code: What It Means & What to Check
Q: My LG dryer is showing PS. What does that mean?
A: On many LG dryers, the PS error code usually points to an improper voltage / power supply problem. This can happen if the cord is miswired at the terminal block, the breaker is tripped/partially tripped, or the outlet voltage is incorrect.
This guide covers homeowner-safe checks you can try first, common causes, and when it’s time to call our friendly technicians in yellow.
Symptoms You May Notice
- PS error code on the display
- Dryer will not start or stops quickly
- Dryer powers on but will not heat/run normally
- Recent installation or cord replacement before the problem started
Safety First (Important)
- Dryers use high voltage. Use extra caution around the power cord, outlet, and terminal block.
- Turn off the breaker before inspecting any cord or terminal block connections.
- If you are not comfortable working around electrical wiring, stop and call for service.
- Do not continue running the dryer if you suspect a wiring issue.
Quick Checks You Can Try First
1) Reset the Breaker Fully
Dryer breakers can partially trip. Turn the dryer breaker fully off, then back on, and try the dryer again.
2) Confirm the Outlet Voltage (Homeowner-Safe if You Have the Right Tool)
If you have a meter and know how to use it safely, confirm the dryer outlet voltage is correct for your dryer setup. If not, this is a good step for an electrician or appliance technician.
3) Ask if the Problem Started After Installation or Moving the Dryer
If the PS code started after a new install, cord replacement, or moving the unit, improper cord wiring at the terminal block becomes more likely.
4) Verify Cord Wiring Matches the Dryer Diagram (Only if Safe and Qualified)
With power off at the breaker, check that the power cord wiring at the dryer terminal block matches the wiring diagram for that model and cord type. Miswiring can trigger PS and create a safety hazard.
Common Causes (What PS Often Points To)
- Improper voltage at the outlet
- Miswired power cord at the dryer terminal block
- Breaker issue (tripped or partially tripped)
- House outlet wiring problem
Likely Parts / Areas a Technician May Check
- Power cord and terminal block wiring
- Terminal block condition (heat damage / loose connections)
- House outlet wiring and voltage supply
- Power input wiring to the dryer
When to Call Beacon
If the PS error returns after resetting the breaker, or if you suspect wiring/voltage issues, it’s best to stop and schedule service. Power supply problems can damage components and may create an electrical safety risk.

Frequently Asked Questions
What does PS mean on an LG dryer?
PS usually indicates a power supply / voltage issue, such as improper voltage, a miswired cord at the terminal block, or a problem with the outlet or breaker.
Can a bad breaker cause an LG dryer PS code?
Yes. A tripped or partially tripped breaker can cause improper power to the dryer and trigger a PS error.
Should I keep using the dryer with a PS error?
No. If you suspect a power or wiring issue, stop using the dryer until the problem is checked. Electrical issues can be unsafe and may damage the dryer.
Can a miswired power cord cause PS after installation?
Yes. If the dryer was recently installed, moved, or had the cord replaced, terminal block wiring that does not match the diagram is a common cause of PS.
Do I need an electrician or an appliance technician?
It depends on the cause. If the issue is in the dryer cord/terminal block, an appliance technician may help. If the outlet wiring or house voltage is the issue, an electrician may be needed.
When should I call for service for an LG dryer PS code?
Call for service if the code returns after a full breaker reset, if the dryer was recently installed and may be miswired, or if you are unsure about safely checking voltage and wiring.
