What Does Error Code PS Mean on a LG Dryer?

Power supply error — improper voltage at the cord or terminal block.

The control monitors incoming line voltage across both hot legs of the 240V supply. PS fires when it detects an out-of-range or absent voltage condition — most often a power cord wired incorrectly, a loose or burnt terminal-block screw, or one hot leg missing from a half-tripped double-pole breaker or a faulty outlet. Unlike nP (no power/plug detection), PS indicates the dryer is receiving power but the voltage present is improper or incomplete for normal operation.

Models affected: LG electric dryers with 240V terminal-block wiring
What owners report: Owners commonly report PS right after installation or after moving the dryer, which points to a miswired or loose cord at the terminal block. It can also appear seemingly at random when one side of the breaker trips, and many find a quick win by simply cycling both halves of the double-pole breaker fully off then on.

What Causes Error Code PS?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Power cord miswired or loose at terminal block 40% of cases
  2. 2
    Loose/burnt terminal block connection 30% of cases
  3. 3
    One 240V leg missing (breaker/outlet) 25% of cases
  4. 4
    Damaged power cord 5% of cases

How to Fix LG Dryer Error Code PS

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check the breaker

    Confirm BOTH halves of the dryer's double-pole breaker are on. A half-tripped breaker leaves one leg dead.

  2. 2

    Inspect the cord and terminal block

    Unplug, remove the terminal cover, and check that the cord wires are tight and undamaged on the block.

    ⚠️ Unplug the dryer before removing the terminal block cover.
  3. 3

    Verify outlet voltage

    Have an electrician confirm 240V across the legs and 120V each leg to ground at the outlet.

How to Reset Error Code PS

Reset both halves of the breaker and confirm the cord is tight at the terminal block, then restart.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

Frequently Asked Questions

Can I keep using my LG Dryer when error PS appears? +
It is not advisable. The dryer may still power on, but running it while PS is active can worsen the power fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes PS on a LG Dryer? +
Across reported LG dryer repairs, the most frequent is power cord miswired or loose at terminal block (40% of cases), loose/burnt terminal block connection (30%), then one 240V leg missing (breaker/outlet) (25%). Check them in that order before replacing any parts.
PS keeps coming back after a reset — what should I check next? +
A reset only clears the stored PS fault; if it returns, the power problem is still present. Move on to the physical checks — check the breaker, then inspect the cord and terminal block — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix LG Dryer error PS? +
A DIY repair typically runs $0–$40 in parts, versus $150–$300 for a professional service call, so handling it yourself saves around $150. Expect the work to take roughly 30–60 minutes.
Which LG Dryer models show error PS? +
PS is documented on LG electric dryers with 240V terminal-block wiring. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
