AE
LG Dryer
Severity: ModerateWhat Does This Error Mean?
The AE error means your LG dryer experienced an auto-restart failure. The dryer attempted to restart after a power interruption but could not complete the restart safely. This is a moderate error — the dryer is protecting itself and your laundry. It is typically caused by power supply issues or a control board communication problem.
Affected Models
- DLGX5002V
- DLE7300VE
- DLHC1455V
- DLEX3700W
- Most LG dryer models with auto-restart feature
Common Causes
- Brief power interruption or power fluctuation interrupted a running cycle
- Home circuit voltage was unstable when the dryer tried to resume operation
- Control board communication error preventing safe restart confirmation
- Door was opened during a cycle and then the auto-restart failed to re-engage
- Software glitch in the dryer's control board firmware
How to Fix It
-
Press the Power button to turn off the dryer completely.
Do not leave the dryer in an error state. Power it off cleanly using the Power button before attempting a reset.
-
Unplug the dryer from the wall outlet for 10 minutes.
This fully drains any residual power from the control board and forces a complete reset of all systems including the auto-restart module.
-
Check your home's circuit breaker for the dryer circuit.
A tripped or partially tripped breaker can cause unstable power that triggers the AE error. Reset any tripped breakers.
-
Plug the dryer back in and start a new cycle from scratch.
Do not try to resume the interrupted cycle — start fresh. Select your cycle settings and press Start to begin a new dry cycle.
-
Monitor the dryer through the new cycle to see if the AE error returns.
If the error only happens when power is interrupted, it may be a one-time event. If it returns on a normal cycle, a control board fault is likely.
When to Call a Professional
If the AE error returns repeatedly after power resets, call a technician. A persistent AE error often indicates a control board communication fault. LG support or a licensed appliance technician can run diagnostic tests. Expect repair costs of $100–$300 depending on whether a control board replacement is needed.
Frequently Asked Questions
What is the auto-restart feature on an LG dryer?
Auto-restart is a feature that automatically resumes a drying cycle after a brief power interruption. Instead of losing your cycle progress during a short outage, the dryer picks up where it left off. If the power was unstable or the interruption was too long, the auto-restart fails and shows the AE error.
Can I disable auto-restart on my LG dryer?
Some LG models allow you to disable the auto-restart feature in the settings menu. Check your dryer's user manual for instructions specific to your model. Disabling it means the dryer won't resume after a power cut — but it also won't show the AE error.
How often does the AE error happen?
For most people, very rarely. It typically happens during storms or when utility power fluctuates. If you see the AE error frequently without any power issues in your home, the control board may have a fault. Frequent AE errors on stable power warrant a professional inspection.
