What Does Error PS Mean?
The LG dryer PS error indicates a power supply issue, which can prevent the dryer from starting or displaying properly. This error is often related to incorrect voltage levels or miswired power cord connections at the terminal block, such as reversed red and white wires. If the error occurs, the dryer may not operate correctly, particularly during startup or heating cycles, due to unstable or improper voltage.
Common Symptoms:
- PS displayed on the control panel
- Dryer may not start or may stop shortly after starting
- Heating may not work correctly due to improper voltage detection
- Error may occur immediately at startup or when attempting to heat
Possible Causes
- Incorrect or unstable supply voltage to the dryer (voltage too high or too low, or not a proper 240V supply for electric models) (medium)
- Improper power-cord wiring at the dryer terminal block (commonly miswired connections such as red/white reversed or loose terminal connections) (medium)
How to Fix Error PS
DIY Fix Confirm proper power supply and perform safe reset
- Turn the dryer OFF and unplug it.
- Wait 60 seconds, then restore power.
- Verify the dryer is plugged into the correct outlet type (electric LG dryers typically require a 240V outlet; do not use extension cords).
- If PS returns, stop using the dryer and proceed to the next steps (wiring/voltage verification).
Technician Only Measure supply voltage and inspect/repair cord-to-terminal-block wiring
- Measure outlet voltage with a multimeter and confirm it matches the dryer’s required supply (for electric models: correct 240V supply and appropriate leg-to-leg/leg-to-neutral readings).
- Inspect the dryer terminal block wiring: confirm correct wire placement per the installation diagram, ensure terminals are tight, and check for signs of overheating/arcing.
- Correct any miswiring (including potential red/white reversal noted in multiple PS reports) and replace damaged power cord/terminal block if heat damage is present.
- If outlet voltage and wiring are confirmed correct but PS persists intermittently, evaluate harness connections and consider control board voltage-detection issues only after confirming the supply side.
Parts needed: Power cord (3-wire or 4-wire depending on installation), Terminal block, Outlet/receptacle and breaker (house wiring), Wiring harness connections (as needed)
- PS returns immediately after a reset and the outlet is known-good/other 240V appliances work normally
- You see any burning smell, melted wiring, discoloration, or arcing marks near the terminal block or cord
- Breaker trips repeatedly or the outlet shows signs of overheating
- You cannot safely verify outlet voltage or wiring configuration
