What Does Error AE Mean?

The LG dryer AE error indicates an airflow issue, which can lead to a lack of heat during drying cycles. This error may be due to restricted ventilation or, in heat pump models, a fault in the compressor system. Users may notice the dryer stopping with the AE code displayed, often accompanied by airflow restriction warnings.

Common Symptoms:

  • Dryer stops with AE displayed
  • Possible airflow restriction warnings
  • Occurrence on heat pump dryer models with compressor components

Possible Causes

  • Airflow or ventilation restriction (medium)
  • Compressor or heat pump system fault on heat pump dryers (medium)

How to Fix Error AE

DIY Fix Check and clean airflow components

  1. Disconnect the dryer from power.
  2. Inspect and clean the lint filter.
  3. Check the dryer vent/duct for lint buildup or blockage.
  4. Ensure the exterior vent hood opens freely without obstruction.
  5. Reconnect power and test dryer.

Technician Only Diagnose compressor/heat pump or internal faults

  1. Verify error with diagnostic tool specific to model.
  2. Check compressor or heat pump unit operation (ohm/resistance and proper cycling).
  3. Inspect internal wiring, sensors, and control boards for faults.
  4. Replace defective compressor or related components if confirmed.

Parts needed: compressor/heat pump assembly, control board, vent sensors

🛑 When to Call a Pro:
  • If the error persists after cleaning airflow paths.
  • If the dryer uses a heat pump system and compressor diagnostics indicate a fault.
  • If there are unusual noises, overheating, or performance issues alongside AE.
