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
- Disconnect the dryer from power.
- Inspect and clean the lint filter.
- Check the dryer vent/duct for lint buildup or blockage.
- Ensure the exterior vent hood opens freely without obstruction.
- Reconnect power and test dryer.
Technician Only Diagnose compressor/heat pump or internal faults
- Verify error with diagnostic tool specific to model.
- Check compressor or heat pump unit operation (ohm/resistance and proper cycling).
- Inspect internal wiring, sensors, and control boards for faults.
- Replace defective compressor or related components if confirmed.
Parts needed: compressor/heat pump assembly, control board, vent sensors
- 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.
