LG Dryer Error Codes

Below are the most common LG dryer error codes (also applies to Kenmore). Each code includes what it means, step-by-step DIY fixes, when to call a professional, and repair cost estimates.

Safety Warning

3 high-urgency code(s) should be addressed promptly. If you smell gas, hear unusual sounds, or see sparks, turn off the system and call a professional immediately.

Quick Navigation — 10 Error Codes

Code d80 Code d90 Code d95 Code tE Code CL Code nP Code PS Code HS Code FO Code E13

LG Code d80: 80% exhaust blockage — airflow significantly restricted

Medium Urgency
Estimated repair cost: $100 – $250

Common Causes

  • Lint buildup in the exhaust vent duct system
  • Crushed or kinked vent hose behind the dryer
  • Blocked exterior vent hood
  • On gas dryers, may also indicate insufficient gas supply

DIY Troubleshooting Steps

  1. Clean the lint screen thoroughly.
  2. Disconnect the vent hose from the dryer and wall. Use a vent brush to clean the full length.
  3. Check the exterior vent hood for lint, debris, or bird nests.
  4. Ensure the vent hose is not crushed behind the dryer.

Call a professional when: You have cleaned all accessible vent sections but the code persists — professional vent cleaning is needed for duct runs through walls or attics.

LG Code d90: 90% exhaust blockage — dryer beginning to shut down

High Urgency
Estimated repair cost: $100 – $250

Common Causes

  • Severe lint buildup in the vent system
  • Vent duct collapsed or severely kinked
  • Multiple blockages along the vent run
  • Vent run too long with too many elbows

DIY Troubleshooting Steps

  1. Stop using the dryer until the vent is cleaned — this is a fire hazard.
  2. Clean the lint screen. Disconnect and clean the vent hose thoroughly.
  3. Clear the exterior vent hood.
  4. If the vent run is long, consider purchasing a dryer vent cleaning kit with flexible rods.

Call a professional when: You cannot access or fully clean the vent duct — professional dryer vent cleaning is strongly recommended at this blockage level.

LG Code d95: 95% exhaust blockage — dryer shutting down for safety

High Urgency
Estimated repair cost: $125 – $300

Common Causes

  • Near-complete vent blockage — extreme fire hazard
  • Vent duct disconnected inside the wall
  • Vent completely crushed behind the dryer
  • Birds nest or animal debris fully blocking the exterior vent

DIY Troubleshooting Steps

  1. Stop using the dryer immediately — this is a serious fire hazard.
  2. Disconnect the vent hose and check for complete blockages.
  3. Check the exterior vent hood — remove any visible obstructions.
  4. Do not run the dryer until the vent system is fully cleared.

Call a professional when: This level of blockage almost always requires professional vent cleaning. Do not continue using the dryer until a professional has cleared the entire vent system.

LG Code tE: Temperature sensor error — thermistor fault

Medium Urgency
Estimated repair cost: $125 – $275

Common Causes

  • Defective thermistor (temperature sensor)
  • Loose wiring at the thermistor
  • Control board not reading the temperature correctly
  • Restricted airflow causing abnormal temperatures

DIY Troubleshooting Steps

  1. Clean the lint screen and exhaust vent — restricted airflow can cause temperature anomalies.
  2. Unplug the dryer for 10 minutes to reset.
  3. Restart with a timed-dry cycle to test.

Call a professional when: The vent is clear and the code persists — the thermistor needs professional testing and replacement.

LG Code CL: Child lock / control lock active — buttons disabled

Low Urgency

Common Causes

  • Control lock feature was accidentally activated
  • Button combination pressed unintentionally

DIY Troubleshooting Steps

  1. Find the control lock button on your model (often labeled with a lock icon).
  2. Press and hold it for 3 seconds to unlock.
  3. On some models, press and hold the Dry Level button for 3 seconds.
  4. Once CL disappears, the controls are unlocked.

Call a professional when: This is not a repair issue. No service call needed.

LG Code nP: No power to gas igniter — gas supply issue (gas dryers only)

Medium Urgency
Estimated repair cost: $150 – $350

Common Causes

  • Gas supply valve turned off
  • Gas line issue or low gas pressure
  • Failed gas igniter or gas valve solenoid
  • Gas supply interrupted

DIY Troubleshooting Steps

  1. Check that the gas supply valve behind the dryer is in the fully open position.
  2. Verify other gas appliances in the home are working to confirm gas supply.
  3. Unplug the dryer for 5 minutes, then try again.
  4. If gas was recently turned off for service, the line may need to be purged.

Call a professional when: Gas supply is confirmed on but the dryer will not ignite — the gas igniter, flame sensor, or gas valve solenoids need professional replacement.

LG Code PS: Power supply error — electrical issue detected

High Urgency
Estimated repair cost: $100 – $300

Common Causes

  • One leg of the 240V circuit lost (tripped breaker)
  • Loose power cord connection
  • Faulty wall outlet
  • Power cord damage

DIY Troubleshooting Steps

  1. Check the electrical panel — turn the dryer double-pole breaker fully OFF then back ON.
  2. Ensure the power cord is fully plugged into the outlet.
  3. Inspect the power cord prongs for damage or burn marks.
  4. For gas dryers on 120V, check the standard outlet and breaker.

Call a professional when: The breaker keeps tripping or you see burn marks on the plug or outlet — call an electrician.

LG Code HS: Humidity sensor error — moisture sensor fault

Medium Urgency
Estimated repair cost: $125 – $300

Common Causes

  • Dryer sheet residue coating the moisture sensor bars
  • Failed humidity/moisture sensor
  • Loose wiring at the sensor
  • Control board fault

DIY Troubleshooting Steps

  1. Locate the moisture sensor bars inside the drum (two metal strips near the lint trap). Clean them with rubbing alcohol and a soft cloth.
  2. Run a timed-dry cycle to bypass the sensor and test if the dryer otherwise works.
  3. Unplug for 10 minutes to reset.

Call a professional when: Cleaning the sensor bars does not resolve the code — the humidity sensor or control board needs professional replacement.

LG Code FO: Duct blockage — flow sense warning

Medium Urgency
Estimated repair cost: $100 – $250

Common Causes

  • Lint buildup in the vent duct
  • Crushed vent hose
  • Blocked exterior vent

DIY Troubleshooting Steps

  1. Clean lint screen before every load.
  2. Disconnect and clean the entire vent hose.
  3. Check exterior vent hood for blockages.
  4. Replace flexible foil vent with rigid metal duct for better airflow.

Call a professional when: All accessible vent sections are clean but the warning persists — professional vent cleaning is needed.

LG Code E13: Slow drainage (combo washer/dryer models)

Medium Urgency
Estimated repair cost: $150 – $325

Common Causes

  • Clogged drain pump filter
  • Kinked drain hose
  • Blocked drain system

DIY Troubleshooting Steps

  1. Clean the drain pump filter.
  2. Check drain hose for kinks or blockages.
  3. Run a drain cycle to test.

Call a professional when: Drain paths are clear but water remains — the drain pump needs replacement.
