AE means the dryer’s main control board and the front display board have lost communication with each other. A loose or corroded wiring connector between the two boards is the most common cause, not a failed board.

LG Dryer Error Code AE (Communication Error)
AE means the main control board and display board have stopped talking to each other, usually a connector issue rather than a dead board.
Meaning
Possible causes
No cause is certain until it has been checked on the appliance.
- Likely Loose or partially unseated wiring harness connector
- Possible Corroded or damaged connector pins
- Possible Main control board failure
- Rare Display or interface board failure
First checks
- Unplug the dryer for 60 seconds to force a full reset, then power it back on.
- If the code returns immediately, unplug and check the wiring harness connectors behind the control panel are fully seated.
- Inspect connector pins for corrosion or bent pins.
- Note whether AE appears constantly or only intermittently, intermittent points more to a loose connector.
What not to do
- Ordering a replacement control board before checking the harness connectors, that's the cheaper and more common fix.
- Repeated power cycling without inspecting the wiring if the code keeps returning.
An error code varies by brand
The same code can have a different meaning depending on the brand and model. Always check your appliance's manual before acting.
