LG Dryer Error Code LE

LG Dryer Error Code: LE — What It Means and Why It Happens

The LE error on an LG dryer stands for a motor-related fault (often reported as a “locked motor” or “motor error”). It appears when the dryer’s control detects that the motor cannot spin normally or the motor’s rotor/tachometer signal is missing or out of range. Causes range from a seized drum, broken or slipped belt, worn drum rollers or idler pulley, to a failing drive motor, damaged wiring, or a faulty control board.

User impacts can include the dryer failing to tumble, longer drying cycles, loud grinding or squealing noises, repeated cycle stoppages, blown thermal fuses, tripped breakers, and in worst cases overheating or burning smells. Because the motor is an electrical and mechanical component, continuing to run the dryer with a suspected motor fault can increase the risk of fire or further damage to the appliance.

Common Causes

• Seized or jammed drum (foreign object stuck between drum and tub)
• Broken, frayed, or slipped drive belt
• Worn or seized drum rollers, bearings, or axle
• Faulty drive motor (electrical failure or seized rotor)
• Faulty motor tachometer or rotor position sensor
• Damaged or loose wiring harness or connector to the motor
• Faulty main control board not reading motor signals correctly
• Overheating / failed thermal fuse or thermostats causing irregular behavior
• Obstructed venting causing the dryer to overwork and trigger errors

Troubleshooting Steps

1. Power cycle: Unplug the dryer or switch off its breaker for 1–5 minutes, then restore power. This clears transient errors and is the simplest first step.
2. Inspect lint filter and vent: Remove lint from the lint trap and check the exhaust vent for blockages. Restricted airflow can cause the dryer to overwork and reveal motor issues.
3. Try to rotate the drum by hand: With the dryer unplugged, open the door and manually turn the drum. It should rotate smoothly with light resistance. Stiff or stuck rotation indicates a mechanical obstruction, seized rollers, or bearings.
4. Check for foreign objects: Look between the drum and the cabinet for coins, buttons, or fabric caught in the drum seal or blower wheel area.
5. Inspect the drive belt: Remove the front or back panel (follow model-specific instructions) to visually check for a broken or slipped belt and confirm correct routing and tension.
6. Examine drum rollers/idler pulleys: Look for flat spots, heavy wear, or seized bearings. Replace worn rollers or pulleys if they don’t spin freely.
7. Check motor for free spin: With power disconnected, try to spin the motor shaft. A motor that won’t turn or is noisy is a likely failure and usually requires replacement.
8. Inspect wiring and connectors: Check the motor wiring harness and control board connectors for loose pins, corrosion, or burnt wiring. Reseat connectors securely.
9. Run the dryer’s diagnostic mode: Many LG models have a self-test or diagnostic mode that will display error codes or help isolate motor vs. control board faults. Consult your model’s service manual for the sequence.
10. Test components (if you’re experienced): Use a multimeter to check motor windings, continuity of thermal fuses/thermostats, and resistance of the tachometer sensor. If you’re not comfortable with live electrical testing, skip this and call a technician.
11. Replace suspect parts: If testing or inspection points to the motor, belt, bearings, or sensors, replace the defective components. After replacement, clear codes and run a test cycle.
12. When to call a professional: If the motor is noisy, will not spin, or you find burnt wiring or control board damage, contact an authorized appliance repair technician—motor and electrical repairs carry safety and warranty considerations.

Maintenance / Prevention Tips

• Clean the lint screen after every load to maintain airflow and reduce strain on the motor.
• Inspect and clean the dryer vent and exterior vent hood at least every 6–12 months.
• Keep the dryer area free of lint buildup around and behind the unit.
• Avoid overloading the dryer — heavy loads increase motor and belt stress.
• Check the drum seal occasionally for trapped objects and remove foreign debris.
• Listen for unusual noises (grinding, squealing) and address them promptly.
• Have drum rollers and idler pulleys inspected and replaced if worn (every few years in heavy-use homes).
• Replace belts at first sign of fraying or glazing to avoid sudden failures.
• Ensure the dryer sits level to prevent uneven wear on rollers and bearings.
• Use the correct vent length and diameter — long, twisting vents increase resistance.
• Use professional installation for gas dryers to ensure proper venting and clearances.
• Schedule periodic professional maintenance if the dryer is used heavily (e.g., laundromats or large families).
• Don’t run the dryer when you’re away for extended periods; catch problems early by monitoring cycles.
• Replace thermal fuses and thermostats with OEM or recommended parts when they fail to keep the dryer safe.

FAQs

Conclusion & Safety Notice

The LE code indicates a potentially serious motor-related problem. If basic checks (power cycle, lint and vent cleaning, manual drum rotation) don’t resolve the code, stop using the dryer and arrange a repair. Motor and electrical faults can present fire and shock hazards; if you are not comfortable performing safe electrical and mechanical diagnostics, call a certified appliance repair technician or contact LG support. Always disconnect power before opening panels and replace parts with manufacturer-recommended components.
